Abstract:

A method of automatic in-line forming of a material stack comprising the steps of feeding a base in sheet form or from a roll to a predetermined position, simultaneously feeding a first layer from a first roll for placement on one side of the base in sheet form and a second layer from a second roll for placement on the opposite side of the base in sheet form. The base, the first layer from the first roll, and the second layer from the second roll are moved together to a cutting station and are advanced a predetermined length. The first layer and the second layer are cut together to the predetermined length to form the desired stack, with the base between the first and second layers. In another aspect, the invention comprises apparatus for automatic in-line forming of a material stack comprising a main frame, a conveyor on the main frame for feeding a base material. A first layer of material is fed from a first roll onto one surface of the base material. A second layer of material is fed from a second roll to the opposite surface of the base. A third roll can be provided from which a third layer is fed onto the first layer. Pinch rollers are provided for moving the base material, the first layer, the second layer and the third layer to a cutting station. A gripper mechanism is associated with the pinch rollers for pulling out a predetermined length of material to be cut when the pinch rollers are released. A fixed blade is provided on one side of the stack and a movable blade is provided on the other side of the stack. The movable blade cooperates with the fixed blade for cutting the predetermined length of material together to form the desired stack of material on both sides of the base material. Controls are provided for coordinating the operation of the pinch rollers, the gripper mechanism, and the fixed and movable blades.
