Abstract: A machine for laying out flat sheets made from tubular fabric in which a horizontal cross bar is hingedly connected to a supporting frame and is in contact with the fabric being fed, so that variations of the tautness of the fabric causes the cross bar to pivot and change the speed of a variable speed drive motor, thereby changing the rate of feed of the fabric.

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.

Abstract: An apparatus attached to the movable carriage of a folding machine for depositing supply rolls of web material into the machine's roll supporting cradle. The apparatus includes a roll elevator frame and a roll guide frame pivotably attached to the carriage with a drive unit operatively connected to the elevator frame for raising and lowering both frames simultaneously between preselected positions. The drive unit pivots the elevator frame and supply roll carried thereby upwardly to a position where the roll is transferred to the roll guide frame and continued upward movement of the frame causes the supply roll to move along the guide frame and then into the machine's cradle.
