DEVICE AND METHOD FOR PRODUCING BAGS

摘要

The invention relates to a device for producing bags (1) from pieces (13) of tubing which can be transported in a transport direction (x) transversally to the longitudinal direction of the pieces of tubing by means of the device (1). The pieces (13) of tubing preferably comprise a fabric consisting of stretched plastic strips (2) and consist of two layers of material arranged one above the other. The device comprises the following components: at least one element (8) for opening an end (13) of a piece of tubing, by which means part of the end of the piece of tubing can be folded back onto a wall of the piece of tubing in order to open the end, such that said opened end can be attached to a bottom; and at least one pressure means for pressing at least parts of the opened end against a counter-layer in order to form fold edges. At least one transport means (30) is used to transport the piece of tubing in the direction of transport (x) once an end of said piece of tubing has been opened and before the action of the pressure means.
