ABSTRACT:
A machine for collating signatures has a pair of side-by-side gathering chains as well as feeding apparatus along the chains, with each feeding apparatus being adapted to open signatures and deposit them on the chain along that apparatus, so that the signatures accumulate on the chain in a saddle format. The compiled signatures are trimmed as they pass along the chain, and at the end of the chain they are discharged into a layup unit where they are turned from a vertical disposition to a horizontal disposition. The layup unit has at the end of each gathering chain a pair of high friction belts which come together at a nip into which the chains project the compiled signatures. The belts grip the compiled signatures near the folds in those signatures and move the depending portions of the signatures against and over a bar which deflects the depending portions laterally and into a horizontal disposition. The two sets of belts in the layup unit discharge the signatures onto a shingling conveyor in two rows, and on the shingling conveyor they overlap in a shingled condition. The shingling conveyor directs the shingled signatures into two stacking machines which arrange them in stacks that are conveniently removed and otherwise handled. The collating machine is very compact and requires a minimum of personnel to operate. Indeed, a single attendant may load the feeding apparatus for both gathering chains.
