Abstract
A bag-making device for cross base bags limits the number of quality defects resulting from the fabrication tolerances of the conveyor belt.The device has working stations that perform working steps on bag tube sections during the bag making operation. At least one working station is equipped with a tool that is mounted on a tool roller and that runs through its working position during each rotation of the roller. The bag-making device has a conveyor system that conveys the tube sections through the working stations with conveyor belts, and a drive system that drives conveyor drive wheels and the tool rollers such that the drive wheels are driven with lesser angular speed than the tool rollers.
