Problems solved by technology

This of course leads to very large distances between the two hose pieces inside the device, so that the production capacity of the device is often not fully utilized

Embodiment Construction

[0037] figure 1 The individual steps, as carried out in the bag manufacturing device 1 , are schematically shown for processing the textile tube into a bag.

[0038] First the textile hose 2 is fed into the bag manufacturing device 1 . This is advantageously carried out by unrolling the textile hose forming the coil 3 in the unrolling device 4 . Subsequently, the hose 2 is so-called opened in the opening station 5 . In this case, the fabric hose is guided around an internal tool which separates the two layers from one another so that the layers are separated if they are bonded to one another in one of the production steps of the hose. Only when the layers are separated can it be ensured that subsequent production steps can be carried out as specified. Subsequently, the mutually separated material layers of the hose overlap one another again.

[0039] The textile hose is now fed to the transverse cutting device 6 , which divides the textile hose into individual hose parts. ...

Abstract

The invention relates to a device for producing bags (1) preferably comprising fabric made of stretched strips of plastic and consisting of two layers of material, one over the other. Such a device comprises: an unwinding device (4) from which tubular material or strip-like material, from which a tube can later be made, can be unwound and displaced in the longitudinal direction (z); a detaching device (6) by which means pieces of tubing (18) can be detached from the tubular material (2); and transfer means (42) by which means the individual pieces of tubing supplied in the longitudinal direction can be transferred onto a continuous transversal transport device (x-direction) or taken by said transversal transport device. The transfer means (42) comprise at least one driving element (29) by which means each piece (18) of tubing can be gripped. The at least one driving element (29) can be held at least in the moment of the piece (18) of tubing.

Description

technical field [0001] The invention relates to a device for producing bags according to the preamble of claim 1 and a method for producing bags according to the preamble of claim 12 . Background technique [0002] Such devices are known and have been commercially available for a long time. Such devices usually firstly comprise a separating device in order to separate the incoming textile hose, which can also be coated, into hose pieces. The hose part comprises two overlapping material webs, which can each consist of a plurality of layers. In addition, the hoses are each clocked forward in their longitudinal direction by the length of the hose piece. Subsequently, the hose piece is separated from the hose, that is to say separated. This is usually accomplished with a cutting tool such as a knife. However, other separation methods and associated devices are also conceivable. [0003] Each hose piece produced in this way is then taken up by at least one conveying device i...
