Apparatus and method for continuous stacking of signatures using opposed floating conveyors
First Claim
1. A signature stacker adapted to the production of stacks of one or more incoming streams of lapped signatures comprising:
- A. a stacker frame having input and output ends;
B. a signature crusher station which is mounted adjacent the input end;
C. a compression conveyor station which is mounted on stream with the crusher station, said compression conveyor station including opposed floating conveyors, at least one conveyor being compressed in contiguous opposition to the other;
said conveyors defining by means of plural rollers a support path for one conveyor to effect an arcuate upward transition from the signature crusher station;
D. a signature receiver station, located on stream of the compression conveyor at the output end of the stacker, said receiver guiding successive signatures into stacking registry with one another;
E. means activating the crusher and conveyor stations.

Abstract
Apparatus and method for continuous collecting, compressing and stacking folded multiple sheet signatures from a press fly end, wherein horizontally conveyed, overlapped signatures are stream-transferred from in-feed to vertical stacking position, the apparatus being characterized by a crusher station and a floating compressor station the latter of which has opposed tensioned conveyor belts which are retained in a face to face uniformly flat, negative angular relationship by multiple series-mounted rollers. The rollers are in compression contact with uppermost floating conveyor belts whereby compression is obtained through the signatures indirectly to tensioned lower conveyor belts, the signatures being thus continuously moved in a stream from a precise, endwise overlapping relationship, to a vertical endwise stacked relationship within a stacking receiver. To enhance the transfer function, a signature kicking apparatus engages each signature as it emanates from the floating conveyors, thereby forcing the signatures vertically upward against a stripper bar in the receiver.
