ABSTRACT:
An apparatus acts upon an extrudate rope to form individual elements of predetermined size and shape which are separated from one another by a predetermined space. A die is used having a predetermined shape with indentations therein to press the extrudate rope against a support at predetermined locations. A conveyor belt is used to carry the extrudate rope in one direction, and the die is supported such that during the pressing operation the die forward speed matches the extrudate rope forward speed. A supporting table underlies the conveyor belt. At least two shims are placed under the conveyor belt on either side of the path of the extrudate rope and underlying the path of the die so that portions of the extrudate rope which are pressed beneath the die are forced from under the die toward the indentations formed in the die so as to minimize waste of portions of the extrudate rope.
