Abstract:
1. A bag making device for cross base bags in which tube sections for the bags are processed, comprising: a plurality of working stations that perform different working steps on the tube sections, at least one of the working stations being equipped with a tool that is mounted on a tool roller and that passes through a working position associated therewith during each rotation of the tool roller, at least one conveyor system that conveys the tube sections through the working stations, the conveyor system including cable cord belts that are driven by drive wheels having a larger diameter than the tool roller, and a drive system that drives the drive wheels and the tool roller such that one tube section passes through the at least one working station each time the tool roller completes a rotation and such that an angular speed of the drive wheels is less than an angular speed of the tool roller; wherein the drive wheels are driven by a transfer of torque from a line gear in communication with a bevel gear that is in communication with a planetary gear that is in communication with the drive wheel.
