Abstract:
An improved machine moves signatures to a work station, stitches the signatures and then moves the signatures away from the work station. The machine includes a conveyor belt assembly having upper and lower belts which grip a signature. The signature is gripped between a lower run of the upper belt and an upper run of the lower belt. When the signature has been moved to the work station, at least central portions of the lower run of the upper belt and the upper run of the lower belt are separated to release the signature. The released signature is accurately positioned relative to a stitcher mechanism by a register assembly which moves the signature relative to the separated upper and lower belts. Once the signature has been stitched, the lower run of the upper belt and the upper run of the lower belt are closed to grip the stitched signature and move it away from the work station. In order to promote accurate positioning of the signature relative to the stitcher mechanism, the upper and lower belts are not driven when they are separated.
