Abstract: An apparatus calipers a signature delivered from a hopper into a collating pocket movable past the hopper. The apparatus comprises a light source and a member supported on the pocket and movable with the pocket relative to the hopper and movable past the light source to interrupt light from the light source. The member moves past the light source to interrupt the light from the light source when a signature is delivered from the hopper into the pocket. A sensor senses non-interrupted light from the light source when the member moves past the light source. The amount of non-interrupted light from the light source is outside of a predetermined range when a misfeed occurs from the hopper into the pocket. Preferably, the member includes a shaft supported on the pocket for rotation about the longitudinal central axis of the shaft and a plate connected to one end of the shaft. The shaft rotates about its longitudinal central axis when a signature is delivered from the hopper into the pocket. The plate moves past the light source to interrupt the light from the light source when the shaft rotates about its longitudinal central axis.
