ABSTRACT:
A feeder device for supporting and unwinding web material from a supply roll in a folding machine. The device is supported by a carriage mounted for reciprocating movement on the machine and includes a conveyor of the driven belt type operatively attached to one end of the carriage. A portion of the conveyor is inclined downwardly and cooperates with supporting surfaces of a selectively movable loader device, mounted on the opposite end of the carriage, to form a hopper-like cradle for supporting a supply roll of web material in position while unwinding the web material and advancing the same to the machine's worksurface where it is caused to be folded into superposed layers.
