ABSTRACT:
A quarter folder machine for accepting half fold signatures and converting them into quarter signatures. The machine receives half signatures in an incoming shingle running at relatively low velocity, strips and accelerates the signatures to travel seriatim in a high speed stream which passes through camming and crimping means to create the quarter fold. A decelerating and re-shingling section then converts the stream back into an output shingle which runs at relatively low linear velocity but at a high rate in terms of signatures per hour--for transport to some subsequent processing device. The machine is characterized by a very high throughput rate. It is flexibly adjustable to match to the velocity of and setback of an incoming shingle from various sources, and yet to determine by choice the setback and velocity of the output shingle.
