i o 146042i o 146042
Opfindelsen angår en maskine af den i indledningen til krav 1 angivne art.The invention relates to a machine of the kind specified in the preamble of claim 1.
Med den kendte maskine af den omhandlede art kunne man ikke arbejde automatisk med tilstrækkelig nøj-5 agtighed, idet der under arbejdsgangen opstod uheldige ændringer i diameteren af røret, specielt siloen, der skulle fremstilles. Længden af røret, henholdsvis højden af siloen var begrænset af den af den kendte maskine fremstillede fals og de forskellige radiale stillinger af de op 10 til hinanden liggende vindinger. Den kendte maskine krævede derfor en løbende overvågning af fremstillingsprocessen, som forudsatte veltrænet personale, og ændringer i rørets eller siloens diameter under fremstillingsprocessen kunne ikke ganske udelukkes. Ved den kendte maskine har man alle-15 rede forsøgt at overvinde de forekommende ulemper ved frem stilling af et rør med stor diameter ved at forstærke falsestationens falsevalser og ved at forøge antallet af false-valsepar i denne station. Disse foranstaltninger har imidlertid ikke i tilstrækkelig grad ført til det Ønskede resul-20 tat, og desto mindre jo tykkere blikbåndet måtte vælges og jo større højden og diameteren af siloen, der skulle fremstilles, var. Den nævnte kendte maskine er omtalt i tidsskriftet "Blech", 1971, nr. 8, sicfe-332 og 333.With the known machine of the kind in question, it was not possible to operate with sufficient accuracy automatically, since during the work process, adverse changes in the diameter of the pipe, especially the silo to be manufactured, occurred. The length of the pipe, or the height of the silo, respectively, was limited by the seam made by the known machine and the different radial positions of the adjacent windings. The known machine therefore required continuous monitoring of the manufacturing process, which required well-trained personnel, and changes in the diameter of the pipe or silo during the manufacturing process could not be completely excluded. In the known machine, attempts have already been made to overcome the disadvantages of producing a large diameter tube by reinforcing the folding rollers of the folding station and by increasing the number of false-roll pairs in this station. However, these measures did not sufficiently result in the desired result, and the less the thickening tape had to be selected and the greater the height and diameter of the silo to be manufactured. Said known machine is mentioned in the journal "Blech", 1971, No. 8, sicfe-332 and 333.
Med den foreliggende opfindelse er det tilstræbt 25 at opnå en bedre beherskelse af profileringen af kanten af blikbåndet, der skal vikles til et rør, og affalsningen af blikbåndets over hinanden liggende vindinger end ved den kendte maskine, samt at gøre det muligt at holde en forud fastlagt diameter af røret eller siloen inden for snævre grænser.It is an object of the present invention to provide a better control of the profiling of the edge of the tin tape to be wound into a tube and the peel-off of the superimposed turns of the tin tape than of the known machine, and to enable a prior art to be maintained. fixed diameter of the pipe or silo within narrow limits.
30 Dette er ifølge opfindelsen opnået ved at udføre maskinen som angivet i krav l's kendetegnende dél.This is achieved according to the invention by operating the machine as set forth in the characterizing part of claim 1.
Ved hjælp af grænseafbryderne kan drivmotoren eller den ene af drivmotorerne for blikbåndet styres således, at der ikke opstår nogen diameterændringer af røret eller 35 siloen under fremstillingsprocessen.By means of the limit switches, the drive motor or one of the gaze belt drive motors can be controlled so that no diameter changes of the tube or silo occur during the manufacturing process.
Krav 2 angiver en foretrukken videreudvikling af ma-Claim 2 indicates a preferred further development of the machine.

2 U6042 skinen ifølge opfindelsen. I praksis styres profileringsstationens motor, og således at denne motor bringes til stilstand, når den yderste afbryder påvirkes af blikbåndet, og således at motoren sættes i gang, så snart den indre afbryder på-5 virkes af blikbåndet. Falsestationens drivmotor, som i blikbåndets fremføringsretning er anbragt efter grænseafbryderne inden for rammen, kan imidlertid også styres af grænseafbryderne, og i så fald er forholdet omvendt. Ved denne styring opnås en ensartet tilførsel af blikbåndet til falsestationen, 10 således at der over hele røret fås en i hovedsagen ensartet formet fals, og således at også den forud fastsatte diameter af røret kan holdes inden for forholdsvis snævre grænser.2 U6042 shin according to the invention. In practice, the profile of the profiling station is controlled, so that this motor is brought to a standstill when the outer switch is affected by the gaze band and so that the motor is started as soon as the internal switch is actuated by the gaze band. However, the drive station's drive motor, which is positioned in the direction of the conveyor belt after the limit switches within the frame, can also be controlled by the limit switches, in which case the relationship is reversed. In this control, a uniform supply of the tin strip to the socket station 10 is obtained so that a substantially uniformly shaped seam is obtained over the entire tube and so that the predetermined diameter of the tube can also be kept within relatively narrow limits.
Anvendelsen af et udligningsarrangement som beskrevet i krav 3 tjener ligeledes til at løse den opgave at holde dia-15 meteren af røret, som skal fremstilles, mest : muligt konstant, idet rørets diameter ved hjælp af udligningsarrangementet kan ændres inden for bestemte grænser. Disse ændringer gennemføres på den måde, at rørdiameteren svinger mindst muligt. Krav 4 og 5 angiver fordelagtige videreudviklinger af udligningsarran-20 gementet.The use of an equalizing arrangement as described in claim 3 also serves to solve the task of keeping the diameter of the tube to be manufactured as constant as possible, since the diameter of the tube by means of the equalizing arrangement can be changed within certain limits. These changes are implemented in such a way that the tube diameter oscillates as little as possible. Claims 4 and 5 indicate advantageous developments of the equalizing arrangement.
Til opnåelse af en rørdiameter, som svinger inden for så snævre grænser som muligt, kan maskinen ifølge opfindelsen være udstyret med de i krav 6 til 8 angivne træk, idet valserne ifølge krav 6 og 7 er indbyrdes indstille-25 lige, og en drivmotor for en støtterulle, ifølge krav 8, kan styres. Denne drivmotor styres på tilsvarende måde som profileringsstationens motor, når den i blikbåndets fremføringsretning ligger foran afbryderne, og på tilsvarende måde som falsestationens motor, når den i båndets frem-30 føringsretning ligger efter afbryderne. Drivmotoren for støtterullen kan også tjene til at assistere drivmotorerne for profilerings stationen og falsestationen, således at der . til "opskruning" af siloen kan være mere end to motorer til rådighed. Dette er især en fordel ved fremstilling af si-35 loer med stor højde og/eller stor diameter. Ved hjælpIn order to obtain a pipe diameter which swings within as narrow limits as possible, the machine according to the invention may be equipped with the features specified in claims 6 to 8, the rollers according to claims 6 and 7 being mutually adjustable and a drive motor for a support roller, according to claim 8, can be controlled. This drive motor is controlled in a similar manner to the profiling station motor when it is in the direction of advance of the tire band in front of the switches, and in a similar way to the motor of the folding station when it is in the forward direction of the belt after the switches. The drive roller drive motor can also serve to assist the drive motors of the profiling station and the folding station so that there. for "screwing up" of the silo more than two engines may be available. This is particularly advantageous in the production of large-height and / or large-diameter screens. Through

Et som helhed med 1 betegnet ringformet stel omfatter en øvre ring 2 og en nedre 3. Hver af ringene 2 og 3 er dannet af adskillige i håndterbare stykker opdelte ringsegmenter. Den 30 øvre ring 2 og den nedre 3 er ved hjælp af i ens indbyrdes afstand anbragte lodrette søjler 4 med rektangulært eller rundt, hult tværsnit forbundet med hinanden i nogen indbyrdes afstand. Ved den i fig. 1 viste udførelsesform findes der 10 søjler, og både den øvre ring og den nedre ring er opdelt i hver tre 35 stykker.A ring-shaped frame as a whole 1 comprises an upper ring 2 and a lower 3. Each of the rings 2 and 3 is formed of several ring segments divided into manageable pieces. The upper ring 2 and the lower 3 are arranged by means of equally spaced vertical columns 4 having rectangular or round, hollow cross-sections connected to each other at some mutual distance. In the embodiment shown in FIG. 1, there are 10 columns and both the upper and lower rings are divided into three three pieces.
På hver af søjlerne 4 er der svingeligt hen mod indersiden af det ringformede stel.1 lejret en svingningsarm 5 med i hovedsagen vandret akse. Svingningsområdet for svingningsarmen er begrænset af en laske 6, der har et langstrakt hul til 4On each of the columns 4 a pivoting arm 5 with a substantially horizontal axis is pivoted towards the inside of the annular frame.1. The pivotal region of the pivot arm is limited by a groove 6 having an elongated hole for 4

På den frie ende af hver svingningsam 5 er der drejeligt lejret en støtterulle 7. Til støtterullen 7 kan der høre en på den samme svingningsarm 5 anbragt modrulle 8, der hindrer 5 en løftning af falsen på det rør, som skal fremstilles. På en af søjlerne er der anbragt en radialt indadragende konsol 9, der i radial afstand bærer to endeafbrydere 10 og 11.On the free end of each pivot shaft 5 a pivot roller 7 is pivotally mounted to the pivot roller 7 there may be a counter roll 8 located on the same pivot arm 5 which prevents 5 a lifting of the seam on the pipe to be manufactured. On one of the columns is arranged a radially inwardly extending bracket 9, which carries two end switches 10 and 11 at a radial distance.
På indersiden af det ringformede stel 1 er der i nærheden af en af støtterullerne 7 anbragt en profileringssta-10 tion 15, som i hver af to planer har otte samvirkende valsegrupper, specielt valsepar med akser, som står vinkelret på den skruelinie, der skal fremstilles, og af disse viser fig. 3 det femte øvre og nedre valsepar 18 og 19. I stedet for en særlig foroven anbragt valse med omtrent lodret akse 15 . kan der også anvendes to valser med omtrent vandret akse, så at tre valser samvirker indbyrdes. Valserne i profileringsstationen 15 er således udformet og anbragt, at sidekanterne af et blikbånd bukkes svarende til fig. 8-13.On the inside of the annular frame 1, adjacent one of the supporting rollers 7 is arranged a profiling station 15, which in each of two planes has eight cooperating roller groups, in particular roller pairs with axes perpendicular to the helical line to be manufactured. and of these, FIG. 3 shows the fifth upper and lower roller pairs 18 and 19. Instead of a specially placed roller with approximately vertical axis 15. For example, two rollers with approximately horizontal axis can be used so that three rollers interact. The rollers in the profiling station 15 are designed and positioned so that the side edges of a tin strip are bent according to FIG. 8-13.
Som vist i fig. 3, er over hinanden beliggende, koaksialt 20 anbragte valser placeret på samme omtrent lodrette aksler 22 og . 23. Mens akselen 22 er stationært anbragt mellem en afdækningsplade 24 og en grundplade 25, kan akselen 23 indstilles på tværs af sin akse, idet der med henblik herpå findes et indstillingsarrangement i området ved lejet. Indstillingsarrangementet har 25 et på afdækningspladen 24 eller grundpladen 25 fastgjort U-for-met stel 26, mellem hvis ben en bøsning, der er indrettet til optagelse af et leje, og hvis ydre omkreds er kvadratisk, er forskydelig i vandret retning. Til begrænsning af bøsningen 27rs forskydningsbevægelse bort fra akselen 22 anvendes en i stellet 26's 30 skiver indskruet stilleskrue 28. Lejerne ved akselen 23's to ender er indstillelige på samme måde.As shown in FIG. 3, coaxially located rollers 20 are located on one another on the same approximately vertical shafts 22 and. 23. While the shaft 22 is stationary disposed between a cover plate 24 and a base plate 25, the shaft 23 can be adjusted across its axis, for this purpose there is an adjustment arrangement in the region of the bearing. The adjusting arrangement 25 has a U-shaped frame 26 fixed on the cover plate 24 or the base plate 25, between whose legs a bushing adapted to receive a bearing and whose outer circumference is square is displaceable in the horizontal direction. To limit the shear movement of the sleeve 27r away from the shaft 22, a set screw 28 screwed into the discs of the frame 26 is used 30. The bearings at the two ends of the shaft 23 are adjustable in the same way.
Afdækningspladen 24 og grundpladen 25 er som vist i fig.The cover plate 24 and the base plate 25 are as shown in FIG.

Hvis der i stedet for en valse med omtrent lodret 5 akse findes to eventuelt indstillelige valser med omtrent vandret akse, når en herunder eller herover anbragt omtrent lodret aksel kun omtrent hen til ringsegmentet 33. En sådan kort aksel er indstillelig i forhold til ringsegmentet 33 på samme måde, som akselen 23 er indstillelig i forhold til 10 ringsegmentet 32 eller 34.If, instead of a roller with approximately vertical axis, two optionally adjustable rollers having approximately horizontal axis are provided when an approximately or equal axis is placed only approximately to the ring segment 33. Such a short axis is adjustable relative to the ring segment 33 of in the same way that the shaft 23 is adjustable relative to the ring segment 32 or 34.
De omtrent lodrette aksler er hver ved deres nederste ende forsynet med ens tandhjul, idet tandhjulene på sammenhørende akselpar, f.eks. på akslerne 22 og 23, er i indgreb med hinanden. Mellem to i indbyrdes indgreb værende tand-15 hjulspar er der indkoblet et mellemtandhjul 43 på en sådan måde, at alle tandhjulene ved fremdrivning af ét af mellem-tandhjulene over et drivhjul 44 for et drev 45 i fællesskab kan fremdrives ved hjælp af en trinløs styrbar drivmotor 46.The approximately vertical shafts are each provided at their lower end with identical sprockets, the sprockets of associated shaft pairs, e.g. on the shafts 22 and 23 are engaged with each other. Between two mutually engaged toothed pairs of wheels, an intermediate gear 43 is engaged in such a way that all the gears can be propelled jointly by means of a stepless steerable gear by propelling one of the intermediate gears over a drive wheel 44 for a drive 45. drive motor 46.
Ved hver af de to sider med størst areal af profile-20 ringsstationen er der anbragt et løbehjul 48, som kan hæves og sænkes, og som er drejeligt lejret i en U-formet slæde 49, der ved hjælp af en stilleskrue 50 kan løftes og seenkes.At each of the two sides with the largest area of the profiling station there is arranged a raised and lowered impeller 48 which is pivotally mounted in a U-shaped carriage 49 which can be lifted by means of a set screw 50 and seenkes.
Slæden 49 føres i en T-formet udsparing i en føringsbane 51. Profileringsstationen 15 står under driften på sin grundplade 25 25 og kan gøres transportabel ved hjælp af løbehjulene 48.The carriage 49 is guided in a T-shaped recess in a guide track 51. The profiling station 15 is in operation on its base plate 25 and can be made transportable by means of the impeller 48.
Falsestationen er vist i fig. 4 og 5. Den er anbragt på et skråt, ringsegmentformet bord 54, der skråner i sin længderetning svarende til stigningen af en skruelinie og på tværs heraf, som omtalt i det følgende. På bordet 54 er der anbragt fire 30 falseenheder 55, der alle, bortset fra deres falsevalser 56 og 57, er ens udformet, se fig. 5. Mellem en bunddel 58 og to sidevægge 59 og 60 er der anbragt et overførselsdrev, som har en i hovedsagen lodret drivaksel 61 med et drivkædehjul 62 og et keglehjul 63, som er i indgreb med et på en i hovedsagen 35 vandret anbragt aksel 65 anbragt keglehjul, der på sin herfra bortvendende ende bærer falsevalsen 56. Falsevalsen 57 er udrejeligt anbragt på en fjernt fra denne valse svingeligt lejret aksel 66, der over et tandhjulsdrev 67 er forbundet med akselen 65, og hvis svingningsstilling er indstillelig ·< 146042 6 o ved hjælp af en mod sidevæggen støttende stilleskrue 68, idet den øjeblikkelige stilling af falsevalsen 57 i forhold til falsevalsen 56 afhænger af falsens tykkelse.The folding station is shown in FIG. 4 and 5. It is arranged on an oblique, ring-segmented table 54, which slopes in its longitudinal direction corresponding to the rise of a helical line and across it, as discussed below. On the table 54 are arranged four 30 folding units 55, all of which, apart from their folding rollers 56 and 57, are similarly shaped, see fig. 5. Between a bottom portion 58 and two side walls 59 and 60, a transfer drive is provided which has a generally vertical drive shaft 61 with a drive sprocket 62 and a cone wheel 63 which engages a shaft 65 arranged horizontally sprocket 57 is pivotally disposed on a distal shaft 66 which is pivotally mounted from this roller, which is connected to shaft 65 by a gearwheel 67 and whose pivot position is adjustable. by means of a set screw 68 supporting the sidewall, the instantaneous position of the seam roll 57 relative to the seam roll 56 depending on the thickness of the seam.
Hældningen af bordet 54 i radial retning har en sådan 5 størrelse, at vinkelhalveringslinien mellem akserne for akslerne 65 og 66 i den i fig. 5 viste stilling for falsevalserne 56 og 57 i hovedsagen ligger vandret. Herved opnås, at falsevalserne 56 og 57 kun ligger an mod falsen ved de mod hinanden vendende sider, mens de øvrige dele af falsevalserne 56 og 57 ligger 10 i nogen afstand fra det rør eller den silo, som skal fremstilles.The inclination of the table 54 in the radial direction is of such magnitude that the angular half-line between the axes of the shafts 65 and 66 in the embodiment shown in FIG. 5 for the seam rollers 56 and 57 in the main case is horizontal. Hereby it is achieved that the seam rollers 56 and 57 abut only the seam at the opposite sides, while the other parts of the seam rollers 56 and 57 lie at some distance from the pipe or silo to be manufactured.
Falsestationen 53 kan drives af en drivmotor 69, der over kæder driver de enkelte falseenheder 55, idet der mellem hver to falseenheder og mellem en falseenhed og motoren er indkoblet et spændehjul 70. Drivmekanismen er således ud-15 formet, at hver kæde kun forbinder to kædehjul indbyrdes, idet der ved hver af de op mod drivmotoren 69 beliggende falseenheder 55 er anbragt to drivkædehjul 62 over hinanden.The latching station 53 can be driven by a drive motor 69 which drives over the individual false units 55 over chains, a clamping wheel 70 being connected between each two false units and between a false unit and the motor. The drive mechanism is designed so that each chain connects only two sprockets 55, two driving sprockets 62 superposed on each of the counterpieces 55 located against the drive motor 69.
I falsestationen 53 frembringes de i fig. 14-18 viste falseforbindelser.In the folding station 53, the ones of FIG. 14-18 showed folding connections.

Maskinen kan ved hjælp af få håndgreb adskilles i let transporterbare dele, idet det ringformede stel 1 adskilles, og profileringsstationen 15 og falsestationen 53 fjernes fra det ringformede stel, hvorved bøjlerne 72 kan fjernes fra 10 bordet 54.The machine can be separated into easily transportable parts by a few handles, separating the annular frame 1 and removing the profiling station 15 and the folding station 53 from the annular frame, whereby the shackles 72 can be removed from the table 54.
Ved profileringsstationen 15 er der anbragt en vinde 83, som tjener til optagelse af en rulle blikbånd. Til føring af blikbåndet inden indløbet i profileringsstationen 15 findes der ved den mod vinden 83 vendende sidevæg af profilerings-15 stationen 15, hvilken sidevæg har et i hovedsagen lodret forløbende, langstrakt hul, et føringsarrangement, der har en ved denne side svarende til højden indstillelig, specielt med et langstrakt hul forsynet føringsplade, på hvilken et øvre føringsorgan og et nedre føringsorgan 84 for blikbåndet er an-20 bragt fortrinsvis indstilleligt. Ved hjælp af føringsorganerne kan den rigtige bredde af den fals, som fremstilles i profileringsstationen 15, indstilles. Føringsorganerne rager ca. 30 cm frem over føringspladen og når omtrent hen til den første valse, idet det nedre føringsorgan 84 som vist kan rage yder-25 ligere frem. Ved hjælp af føringsorganerne kan blikbåndet ved indløbet i profileringsstationen 15 trykkes nedad eller opad. Føringsorganerne kan være udformet lige eller krumme samt være anbragt skråt. Vinden 83 har på sin stationære del en i retning mod det ringformede stel 1 åben begrænsningsring 85, der omgi-30 ver blikrullen i nogen afstand fra denne og hindrer en for kraftig diameterforøgelse af blikrullen, når drejebevægelsen af denne forsinkes.At the profiling station 15 there is arranged a winding 83 which serves to receive a roll of tin tape. For guiding the gaze band before the inlet into the profiling station 15, there is provided at the side wall facing the wind 83 of the profiling station 15, which sidewall has a generally vertical extending elongated hole, a guide arrangement having a height adjustable at this side , in particular with an elongated hollow guide plate, on which an upper guide member and a lower guide belt 84 for the tin strip are preferably adjustable. By means of the guide means the correct width of the fold produced in the profiling station 15 can be adjusted. The guide members project approx. 30 cm forward of the guide plate, reaching approximately to the first roller, the lower guide member 84 as shown further projecting. By means of the guide means, the gaze band can be pressed downwards or upwards at the inlet of the profiling station 15. The guide means may be straight or curved and may be inclined. The wind 83 has on its stationary part a restriction ring 85 open in the direction of the annular frame 1, which surrounds the eye roll at some distance from it and prevents excessive diameter increase of the eye roll when the rotational movement thereof is delayed.
I fig. 7 er der vist en fremdrivelig, på en akse 87 monteret støtterulle 70, som ved hjælp af en drivmotor 88, 35 hvis omdrejningstal er trinløs indstilleligt, kan drives rundt via en ikke vist kilerem.

Med henblik på fremstilling af en silo samles maskinen på et til siloen indrettet monteringssted, såsom en betonplade, på den i fig. 1 viste måde, idet afstanden mellem de to ringe 10 2 og 3 i det ringformede stel 1 fortrinsvis er større end den dobbelte stigning af skruelinien for det rør, som skal fremstilles, mens den af rullebanen bestemte bane for blikbåndet i profileringsstationen forløber i ringe afstand fra den af støtterullerne 7 bestemte skruelinie. Den øverste ring i det ring-15 formede stel 1 kan også forløbe som en skruelinie, idet de hen over hinanden forløbende ender kan være forbundet indbyrdes ved hjælp af en lodret forbindeisesstøtte. Den øverste støtterulle 7 ligger fortrinsvis i en højde, som mindst svarer til det dobbelte af stigningen af det rør, som skal fremstilles. 20 Båndets bane inde i profileringsstationen 15 er således udformet, at båndets rande bukkes svarende til fig. 8-13, mens den mellemliggende del af båndet bøjes svarene til diameteren af det rør, der skal fremstilles.For the purpose of manufacturing a silo, the machine is assembled at a mounting site arranged for the silo, such as a concrete slab, in the manner shown in FIG. 1 in that the distance between the two rings 10 2 and 3 in the annular frame 1 is preferably greater than the double increase of the helical line of the pipe to be manufactured, while the path of the gaze band in the profiling station in the profiling station runs at a small distance. from the helical line defined by the support rollers 7. The upper ring of the annular frame 1 may also extend as a helical line, the transverse ends of which may be interconnected by means of a vertical connecting support. Preferably, the upper support roll 7 is at a height equal to at least twice the rise of the tube to be manufactured. 20 The web of the tape inside the profiling station 15 is designed so that the edges of the tape are bent according to FIG. 8-13, while the intermediate portion of the tape bends to the diameter of the tube to be manufactured.
Blikbåndet, der kommer fra vinden 83, føres til 25 profileringsstationen 15 og bæres derefter som vist i fig. 6 ved sin øverste bukkede rand af støtterullerne 7, idet disses øversté krans altid ligger an i området ved det bukkested, som er beliggende ved rørets lodrette væg. Blikbåndet føres med sin nederste ende ind mellem endeafbryderne 10 og 11, 30 af hvilke den ydre endeafbryder 10 formindsker omdrejningstallet for profileringsstationen 15's drivmotor 46, mens endeafbryderen 11 forøger omdrejningstallet for denne motor, hvorved der opnås en styring svarende til omdrejningstallet af drivmotoren 69 for falsestationen 53. Efter endeafbryderne 35 10 og 11 føres det ved begge sine kanter bukkede blikbånd gennem falsestationen, hvor de mod hinanden vendende kanter af 0 146042 9 blikbåndet efter i forvejen at være bragt i indbyrdes indgreb; som vist i fig. 14/forbindes fast med hinanden ved falsning, som det er vist i fig. 15-18, så snart der ligger to vindinger over hinanden.The tin strip coming from the wind 83 is fed to the profiling station 15 and then carried as shown in FIG. 6 at its uppermost curved edge of the supporting rollers 7, the uppermost wreath of which is always in the region of the bending point located at the vertical wall of the tube. The tin strip is inserted with its lower end between the end switches 10 and 11, 30 of which the outer end switch 10 decreases the speed of the profiling station 15 of the profiling station 15, while the end switch 11 increases the speed of this motor, thereby obtaining a control corresponding to the speed of the drive motor 69 53. After the end switches 35 10 and 11, at each of its edges, tin strips are passed through the folding station, where the opposite edges of the tin strip are previously interposed; as shown in FIG. 14 / is firmly connected to each other by folding, as shown in FIG. 15-18 as soon as two turns are over.
5 Røret eller siloen fremstilles på den nævnte måde kon tinuerligt, idet røret svarende til sin højde langsomt skrues opad. Så snart den ønskede højde af røret er nået, afskæres det plant forneden. Profileringsstationen 15 og vinden 83 fjernes fra det indre af det ringformede stel 1, og også de ind-10 vendigt beliggende dele af falsestationen 53 og udligningsarrangementet 73, 74a samt konsollen 9 med endeafbryderne 10 og 11 fjernes. Derefter sænkes røret ved drejning i den modsatte retning, indtil det står på underlaget.5 The pipe or silo is manufactured in the said manner continuously, with the pipe corresponding to its height slowly being screwed upwards. As soon as the desired height of the pipe is reached, it is cut flat down. The profiling station 15 and the wind 83 are removed from the interior of the annular frame 1, and also the internally located portions of the folding station 53 and the compensating arrangement 73, 74a and the bracket 9 with the end switches 10 and 11 are removed. Then lower the tube by turning in the opposite direction until it is on the ground.
Den grafiske fremstilling i fig. 19 viser gunstige 15 falsebredder F i mm som funktion af diameteren D i m af røret i afhængighed af tykkelsen af blikbåndet, idet kurven a gælder for en bliktykkelse på 1-2,5 mm, kurven b for en bliktykkelse på 2-5 mm og kurven o på en bliktykkelse på 4-8 mm. Afvigelser på + 50% fra de angivne værdier er mulige.The graphical representation of FIG. 19 shows favorable 15 seam widths F in mm as a function of the diameter D in of the tube depending on the thickness of the tin strip, the curve a applies to a sheet thickness of 1-2.5 mm, the curve b for a sheet thickness of 2-5 mm and the curve o at a thickness of 4-8 mm. Deviations of + 50% from the specified values are possible.
