"Carrying bag with handle, method of making them and device for the implementation of the process "

The invention relates to a carrying bag Mt handle, primarily Made in plastic material, intended for multi-purpose use, especially for delivery by the large Goods transactions to their customers in order to include the purchased goods. It is obvious that their prime costs must be reduced to a minimum, which is also due to a special manufacturing process and by a device is achieved that is attached to the automatic and semi-automatic welding and manufacturing machines for bags used at the time and through which the

Process can be realized.

The handle of the carrier bag consists of two flat, identical, mutually conformable half-handles, one with one wall of the pocket, the other connected to the other wall is, each half-handle has a part protruding from the pocket, with an opening for the insertion of the fingers is provided, as well as a not protruding part, which with the Side wall of the bag is connected. The carrier bag is "characterized in that the mentioned, not protruding part of the Handle essentially has a U-profile and with the outstanding Part forms a complementary part and this so that several Handles can be cut from a strip without waste and the connection to the pocket wall along the named U-profile, i.e. parallel to the opening as well perpendicular or approximately perpendicular to the opening itself, for the purpose Achievement of an increased resistance to departure and consequently an increased carrying capacity of the bag takes place; one of the two openings ! furthermore has a corresponding tongue, which by the partially Cutting the opening itself is obtained, said Tongue, after being bent around 180, is used for this purpose to hold back the other half-grip compared to the first and to make it easier to grip the handle with your fingers

According to the present invention, the method of manufacture is of the present carrier bag characterized in that:

- assumed a pair of stripes to form the half-grips

- that the advance of the above-mentioned pair of strips with the intermittent Feed movement of the material used to produce the pockets is synchronized and in its context the two openings inside the half handles and the two half handles themselves are cut!

- that in the superposition point of the two strips with the to Formation of the pocket certain material during the standstill phase of the intermittent movement, the welding of the half handles done with the walls of the pocket;

- that the separation of the finished carrier bag by the above automatic or semi-automatic machines.

Referring to Fig. 1 up to and including ^F ± g x 5, the carrier bag consists of the body 1 made of thermoplastic material (Fig. 3) and of the half handles 2-3 (Figs. 1-2-3) made of thermoplastic material Cardboard or other material coated with thermoplastic films

The two half handles 2-3 are of the same shape and have a special profile, which has a part ABCD (Fig. 1 and 3) that protrudes over the pocket and has an opening k for inserting the fingers, as well as a part that does not protrude from the pocket EFGH which is attached to one wall 1 * or to the other I ″ (FIG. 3) in the pocket 1β%;

The not outstanding part EFiSH essentially has a U-Prof il up and forms a fermentation with your dominant part ABCD and züar so that several handles from one strip starting from öiiiie waste can be cut ^

The U-profile also fulfills the very specific task of connecting each half-handle with the outer pocket _} and this not only runs parallel to the opening U (Fig. K) but also along the lines Ik and LN perpendicularly to the said

Opening k , whereby the resistance to departure is noticeably increased

The mentioned connection along the line MILN is made by welding, especially since the half-handles are made of thermoplastic material or made of material which is coated with thermoplastic films was, exists

Another detail of the handle described is that one of the handles, for example the half-handle 3 along the side OP, adheres the tongue k * , which is obtained as a result of only partial cutting of the opening k by folding the tongue 180 in the direction of the arrow 26 (Fig * 5) are "fie two half-handles combined and thereby the hand touch facilitates f sd ie support surface with respect to the fingers undergoes characterized an enlargement" while the pressure on the same, due to the quantity of the stored in the pocket Vare is decreased *

The method * the subject of the present invention, for the preparation the bag described above results from the following operations ι

for bags and, if this is tubular, in the longitudinal direction in the above-mentioned pair of strips 17-18 facing fold line is cut open *

- that the advance of the above-mentioned pair of strips 17 * 18 is synchronized with the intermittent advance movement 31 of the material 1 »-1" used to produce the pockets and, in connection with this, the two openings k inside the half-handles and the two half-handles 2-3 themselves / get cut!

- that, in the superposition point 33 (. ^F ig 6) of the two strips 17-18 nit the particular to form the bag material (l '-L *) during the standstill phase of the intermittent movement of the welding of the half-handles (2-3) nit the walls the bag takes place

In this context, it is assumed that the two parts 1 * -1 »(Fig. 6) of the tubular film _t A ** ^for forming the walls of the pocket is intended by the automatic or semi-automatic machine mentioned at the beginning of the production process and in Bexug are folded onto the bottom of the pocket so that the two drawn-in V-shaped parts l ^tN are formed with apex XY as in Fig. 6 and Flg. 3 is shown.

The device according to the present invention for the implementation of the method just described is shown in FIG. 7.8. This includes two roles kl-hZ ^ of which two are different

mutually distant, to form the two half-grips 2-3 starred · Unwind strips 17-18.

The cutting tools 43-44 are used to make the opening 4 the half handle 2 of one strip and the partial opening Cut 4 from half-handle 3 of the other strip by the tongue 4 * (Fig. 5) with the half-handle itself along the side OP (Fig. 4) remains connected.

After the above-mentioned son's operations, the rollers approach the two strips 17-18. The organs 7-8-15 determine the intermittent feed movement of the strips 17-18, which are introduced at the level of the openings of the walls 1'-1 ^N in the form of a tube, moving in the direction of arrow 31 (FIG. 8) *

The organs 7-8 (Fig. 7) consist of two pushers, soft alternatively operated. As soon as the pusher 8 has lowered onto the pair of strips 17-18, the compressed air piston causes it 15 a partial advance in the direction of arrow 30 of the two strips 17-18 on the one hand, and a partial » Advancing the above-mentioned pusher 8 on the other hand, while. the pusher 7 remains lifted.

As soon as the organs 8 and 15 have reached the end of their path, the pusher 7 lowers, the pusher 8 lifts off and turns eo as well as the piston 15 ■ back to the starting position.

With the lowering of the cutting elements 43-44, the piston provided with the shaped blade 10 and epee blade 14 also lowers at the same time 9 and performs the separation of the two half-handles according to the

Profile ABCD »Consistent with profile ES ¹ CrH of the adjoining half-handle. At the same time, the jaws 11-12 weld the half-handles with the corresponding walls of the bag.

The welding of the sides of the bag as well as the separation of the manufactured pocket take place simultaneously with the welding process by the welding jaws 11-12 «
