Abstract

The invention relates to a device for producing corner foldovers on tubular bag bodies using a folding tool, which can be introduced into a bottom opening of a bag body to produce a corner foldover. To increase the throughput and the reliability of the device, a linear transport system is provided with at least one mover, the folding tool being fastened to the at least one mover.
