Block formation system and method for controlling the folding of a block
First Claim
1. A system for forming a block of folded material, comprising:
- a folding means between which web material is passed for folding the web material into a block;
a pressing means for pressing layers of the web material into a block;
a lifting element receiving and supporting the block;
a moving means for moving the lifting element relative to the folding means; and
a controlling means for controlling the moving means as a function of degree of compression in the block.

Abstract
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.

10. A method for controlling the folding of material into a block, comprising the steps of:
-
feeding web material to a folding device;
folding the web material in a zigzag manner, thus building a block of folded material on a lifting element;
compressing an uppermost web layer onto the lifting element with a press;
measuring a degree of compression in the block; and
controlling relative movement of the lifting element with respect to the press based upon the measured degree of compression. - View Dependent Claims (11, 12, 13, 14, 15)

16. A system for forming a block of folded material, comprising:
-
a folding mechanism which folds a continuous web of material into a block, the folding mechanism including a pair of mutually parallel and counter-rotating cylinders between which the continuous web of material is fed, a grip formed on each of the cylinders, a pushing device formed on each of the cylinders, the grips and pushing devices are positioned such that as the cylinders rotate, the pushing device from one cylinder pushes material into the grip of the other;
a lifting element receiving and supporting the block;
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 in response to the degree of compression in the block. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25)
