A system for forming a block of folded material, and a method for folding material into a block. The system includes a folding mechanism, a lifting element receiving and supporting the block of folding material, a press acting on the block to compress an uppermost layer of the web material onto the block, a sensor detecting a degree of compression in the block, and an actuator capable of moving the the lifting element relative to the folding mechanism. The actuator moves the lifting element in response to the degree of compression in the block. The folding mechanism is made up of a pair of mutually parallel and counter-rotating cylinders between which the continuous web of material is fed. A grip and a pushing device are formed on each of the cylinders, and are are positioned such that as the cylinders rotate, the pushing device from one cylinder pushes material into the grip of the other. |
