Abstract

The invention relates to a device for opening tubular bag shapes which are open at at least at one end, comprising at least one slide which can be introduced into an open end of a bag between the bag walls, in order to at least partially fold over at least one end area of a bag wall. According to the invention, the at least one slide (3) can be moved in and out of the bag end to be opened by means of at least one, driven cam (9) which can be moved along a predetermined path (8) and which engages with the slide (3). The slide (3) preferably takes a circular path (4), said circular path comprising a section which runs parallel to a bag-transporting device. The speed of transportation of the bags (2, 2a) on the conveyor device (1) and that of the slide (3) around the circular path are equal.
