Abstract
A positive drive mechanism for use in a sheet folding apparatus includes a motor drive, a torque-limiting device coupled to the motor drive, a drive pulley coupled to the torque-limiting device, and a plurality of idler pulleys. Each of the idler pulleys is coupled to a drive shaft which supports a fold roller. A non-slip positive drive member operatively engages portions of the drive pulley and the plurality of idler pulleys. A sheet is fed into the folder and between the fold rollers in order to fold the sheet. In the event that the sheet becomes jammed between the fold rollers, the torque-limiting device operates to release the torque transmitted from the motor drive to the drive pulley.
