Description

       

   <EMI ID=1.1> 

  
Cette invention a pour objet des perfectionnements apportés

  
aux machines tordre.

  
l'un des perfectionnements a pour but d'obtenir l'arrêt

  
automatique et individuel de chaque broche lorsque le fil on

  
l'un des fils du toron qui y est formé se casse,en même temps

  
que le rouleau de pression de la paire de rouleaux d'entrainement correspondante se soulevé. De cette manière on évite toute

  
perte de fil du fait de l'enroulement de celui-ci sur le rouleau

  
de pression et on obtient que le fil que l'on fabrique est

  
complètement uniforme et possède le même nombre de brins. 

  
Un autre perfectionnement se rattache à la construction de la broche, qui est indépendante, de la poulie recevant le mouvement de commande et à laquelle elle est réunie par un simple embrayage conique à friotion quand elle tourne avec celle-ci, mais qui s'en sépare lorsque cela est nécessaire pour le toron;

tue automatiquement quand le toron ou l'un des fils qui le constituent se casse ou se relâche. En outre, ce perfectionnement

  
 <EMI ID=3.1> 

  
ne et automatique de toutes les parties de la broche qui l'exigent, l'huile circulant constamment en direction ascendante et descendante.

  
Les machines à tordre pourvues de ces perfectionnements, :
en outre des avantages dérivant directement de ceux-ci et qui  ont déjà été signalés, présentent l'avantage très important que

   <EMI ID = 1.1>

  
The object of this invention is improvements made

  
to twist machines.

  
one of the improvements aims to obtain the stop

  
automatic and individual of each spindle when the wire is

  
one of the threads of the strand formed therein breaks, at the same time

  
that the pressure roller of the corresponding pair of feed rollers is raised. In this way we avoid any

  
loss of thread due to its winding on the roller

  
of pressure and we obtain that the wire that we manufacture is

  
completely uniform and has the same number of strands.

  
Another improvement relates to the construction of the spindle, which is independent of the pulley receiving the control movement and to which it is joined by a simple conical clutch with friction when it rotates with it, but which does not. separates when necessary for the strand;

  
 <EMI ID = 2.1>

  
automatically kills when the strand or one of its constituent wires breaks or slackens. In addition, this improvement

  
 <EMI ID = 3.1>

  
and automatic of all parts of the spindle that require it, the oil circulating constantly in upward and downward direction.

  
Twisting machines fitted with these improvements:
furthermore, advantages deriving directly from them and which have already been pointed out, have the very important advantage that

  
 <EMI ID = 4.1>

  
will be described below, they can be used simultaneously as doubling machines, so that both operations

  
 <EMI ID = 5.1>

  
china, oe which represents a saving of time, a saving of manpower, a reduction in the price of the mechanical installation and a reduction of. the location occupied by it.

  
The attached drawings represent, in a somewhat schematic form, an exemplary embodiment of the improvements! indicated above ..

  
 <EMI ID = 6.1> <EMI ID = 7.1> FIG. 2 is a sectional view of the brocade oonstrui ... te according to the invention; and Figure 3 shows the bushing separated from this pin.

  
 <EMI ID = 8.1> shown in the drawings for clarity - for routing

  
 <EMI ID = 9.1>

  
 <EMI ID = 10.1>

  
 <EMI ID = 11.1>

  
provided in the vertical direction with a hole in which is mounted a thread guide II, through which passes the thread which, coming from the

  
 <EMI ID = 12.1>

  
son rests by its lower part on a part which forms fins or arms 12, which is mounted on an axis 13, extending along the machine and rotating continuously as long as it is in operation.

  
 <EMI ID = 13.1>

  
by means of a connecting rod 14, to another rod 15 whose axis of rotation is at 16 and which, at one of its ends, forms a fork 17 which acts on a conical clutch of the spindle with the motrioe pulley corresponding 18. At the opposite end

  
 <EMI ID = 14.1>

  
of each spindle, in the way which will be deorite hereinafter.

  
In addition, this rod 15 is subjected to the action of a spring 21 via a connecting rod 22 and a rod 23 whose axis of rotation is at 24 and is located on a support 25 forming body with the frame 3 of the machine.

  
This device works as follows:
When the machine is running normally, the assembly deorit remains as shown in the drawing, i.e.

  
 <EMI ID = 15.1>

  
raised so that part 12 can rotate freely. If this thread becomes loose or slack, the thread guide II falls out and one of the <EMI ID = 16.1>

  
abutment, so that the rod 15-17 lifts the pin 2 which then

  
 <EMI ID = 17.1>

  
the pressure water 5 which loses its contact with the lower roller 4.

  
After reattaching the broken wire, to

  
 <EMI ID = 18.1>

  
machine and runs in a uniform way; as long as it

  
 <EMI ID = 19.1>

  
 <EMI ID = 20.1>

  
of the threads which one wants to join together breaks, one will also obtain and in the manner indicated in detail the stop.de.la corresponding pin.

  
 <EMI ID = 21.1>

Claims

freely on an extension 27 formed by the support 28 of

spindle. This pulley extends to its upper part

by a tronic body 29 on which fits another piece 30 of corresponding inner surface and forming a body

ment an annular oanal 31 in which the fork fits

axis by a part 32. To obtain the lubrication of the

it turns, the rod 2, present on its part which fits

in the corresponding bearing 33 a helical groove

34 by means of which the lubricant is returned to the part

along the extension 27, which, for this purpose, has striations

indicated in 36, and, gathering in an oanal 37 formed by

the piece 27 on which the lower end of the

part 33 by the holes 38 made at the bottom of the aforesaid oanal.

In addition, in the upper part of the part 30 are formed holes 39 for air circulation.

The refinements may vary

in their practical embodiments, according to the types, olasses and systems of twisting machines to which they are applied,

and according to the pin systems used for this purpose.

CLAIMS:

essentially consist in that each of the pins is

independent of the corresponding pulley which receives the control movement, the connection of these two components being effeo- <EMI ID = 29.1>

for each spindle an articulated system thanks to which, when the strand or one of the wires which form the latter breaks, automatically disengages the spindle and its pulley, and thereby also the stoppage of the spindle and at the same

of the corresponding pair of drive rollers.

2, .. Improvements to twisting machines, characterized in that the movement of the artioulé system which actuates the clutch of each spindle and its corresponding pulley and which lifts the pressure roller, is produced by an axis arranged all along of the machine and rotating in a uniform way as long as the machine is running, and in oe only on this axis and

for each spindle is mounted a part which forms protrusions

or fins and above which is disposed an oscillating part which carries the thread guide, which is held in a raised position as long as the thread passes through its thread guide, while if the thread breaks, the guide- son falls down and hits one of the fins of the part receiving a rotational movement, which by its movement causes the part to move in 'la-

spring and thereby disengage the corresponding spindle and lift the pressure roller.

3.- Improvements to the following spindles.

of the friction surface of the pulley on the rotating part, improvements consisting essentially in that one

helical groove by which the lubricant is ascended to the upper part of the part on which the pulley is mounted and then spreads along the friction surface until it arrives at the lower part of the pulley in a channel in which the edge of the latter fits in and in which holes are made through which the oil passes again inside the spindle support, and only in the upper part of the part which forms the clutch oonic with the pulley are made holes of communication with the atmosphere. "

consist essentially of that the oscillating part mentioned in claim 2 has an appropriate number

from this part and at an appropriate distance from the corresponding drive device a second fixed yarn guide in which the yarns coming from the aforementioned yarn guides gather, for the purpose of using the twisting machine; thus arranged, simultaneously as a doubling machine with two, three or more strands.

5.- A twisting machine in substance as described above and shown by way of example, in the accompanying drawings.
