/ Bags or carrier bags made of thermoplastic plastic film connected to a chain. \

The invention relates to a chain Bag ouer T: agetaschen made of thermoplastic plastic film, with the two on top of each other Foil layers at intervals corresponding to the length of the bag are provided with a bottom seam weld at right angles to the film tube and on one side next to the Bottom seam welding in a foil layer Cross cut to create a bag filling opening is in progress.

Carrying bags or carrier bags have so far been produced in such a way that they arise individually and in pieces. 1. They are stacked on top of each other and Transported to the place of use. The disadvantage is that uie carrying bags for packing the contents by hand need to be opened. Also is the grasping of the individual

Bags by hand to take from a pile., comparatively cumbersome. Especially in self-service shops, where the purchased goods are previously packed by hand in bags at the checkout, this requires a lot of time, which delays the handling of customers.

The invention is based on the object of eliminating the disadvantages described above and a carrier bag system and to create a packaging system, which is characterized by further advantageous properties excels. To solve this problem, in the case of a bag chain or carrier bag chain, the at the beginning mentioned type proposed according to the invention that in the area of the filling opening through both bag walls There are punched holes throughout and next to and parallel to the bottom weld a transverse perforation opposite the transverse severing cut is present in the coherent film layer is, through the remaining webs of which the individual bags or pockets are connected to one another.

The proposal according to the invention thus includes the production and design of bag or pocket chains, wherein the pockets are also provided with filling openings in the contiguous arrangement. The individual pockets

S92653326.10.72

can be detached from the belt \ of the pockets by applying low tensile forces. The inventive

Proposal now solves various problems by producing finished bags that are, however, connected Problems. Stacking the bags is simplified because the bags are connected. So let yourself be stack in close proximity to each other in various ways.

It is particularly advantageous if they can be wound up into a roll. The proposal according to the invention includes Furthermore, that the pockets, even connected to form a band, can be filled individually, so that the It is possible to separate the pockets from the tape of the pockets only after they have been filled.

The invention can be implemented in a wide variety of pocket designs. Particularly The invention is advantageous in connection with the further measure that starting from a hose made of thermoplastic plastic film punched handle holes attached to both carrier bag walls in the area of the filling opening and the carrier bags be provided with a bottom weld, in close connection to the transverse to the hose Bottom weld seam on one hose wall

perforated across the width of the tube and the other opposite The hose wall is provided with a separating cut across the width of the hose, the thus obtained, Finished bags connected by the webs of the perforation, stacked to save space and ready for use transported and there the pockets in the perforation line are separated from the .. Band aer Tascr.en.

The measure described above includes. That the pockets are made starting from a tube, whereby the tube can be blown, but can also be formed in such a way that, starting from a flat sheet, it is turned over to form a half tube and the edges that are then attached are welded together to form a tube. If, according to the proposal according to the invention, the finished _{carrier bags are wound together to form a P 1} oil and this supply roll is transported to the place of use and the individual carrier bags are separated from the belt of the bags with the unwinding of the supply roll, then it is particularly advantageous that with the Unwinding the supply roll, the carrier bags are filled and the carrier bags are separated from the tape of the carrier bags by tearing them off after they have been filled in the perforation line. Advantageously in connection with this measure is after a

are supported on respectively assigned rollers 36 to 6c located outside the hose. This carriage y \ is available in order to insert the aforementioned side folds 22 and 2 ^ on one side and 24 and 25 on the other side in connection with side swords (not shown). The carriage ^ 4 is extended by a plate or the like frame yj. At its end there are two cutting counter-supports, namely the upper cutting counter-support yo, which interacts in connection with the cutting knife 4o arranged outside the S -hlauchwandung Ij5 and the lower cutting counter-support 39. » which interacts in connection with the perforation knife 4l arranged outside of the hose wall 12. Following this cross-cutting and cross-perforation, the cross-weld 11 is carried out with the hose moved in the indicated arrow direction 42 over the two welding bars 4j> and 44, which, viewed locally, however, in the indicated direction of movement of the hose, lies in front of the cross-cut and the cross-perforation 14, as is also shown in FIG 5 shows.

FIG. 7 shows, as a modification of FIG. 4, that the supply roll 26 is unwound in connection with a deflection roll 45, in order to always have the same distance between the chute 28 and the bag opening. There is also a feed belt 46 for the filling material 27. Furthermore, the deflection roller 45 is advantageously designed as a feed roller, which the interconnected carrier bags intermittently each by their length transported forward.
