ABSTRACT:
An improved signature stacking apparatus includes an assembly which feeds signatures across a stack of signatures toward a register surface. As the signatures are moving toward the register surface, they are engaged by a precompressor assembly which applies a force to a leading end portion at each of the signatures in turn to urge the signature forwardly against the register surface and to press the leading end portion of each signature downwardly against other signatures in the stack of signatures. The precompressor assembly incudes a pair of arcuate paddles which extend outwardly from a rotatable hub. The speed of rotation of the hub is such that outer side surface areas of the paddles are moving at a speed which is greater than the speed of movement of the leading end portion of the signatures. Therefore, upon engagement of an outer side surface area of a paddle with a signature, the signature is accelerated toward the register surface. At the same time, the paddle applies a downward force against the leading end portion of the signature to press the signature downwardly toward the stack of signatures.
