ABSTRACT:
The present invention is a pair of split dies comprises of a pair of fixed die halves, with each fixed die half having an associating movable die insert. The pair of split dies are separated from each other in order to admit a cutting blade therebetween and a variable width opening is formed between each of the fixed die halves and their associating movable die inserts. The movable die inserts move toward the fixed die halves and thereby decrease the width of the openings in response to cam means attaching to the blade which engage movable cam tracks located on the movable die inserts opposite the openings. The openings close on tubing located within the openings so that the tubing is held stationary on either side of where the blade cuts the tubing. The movable die inserts move away from the fixed die halves and thereby increase the width of the openings in response to disengagement with the cam means. When the cam means are disengaged from the movable die inserts, die springs located in spring pockets provided in the fixed die halves push the movable die inserts away from the fixed die halves, thus releasing the tubing and allowing it to move quickly through the openings as the dies are repositioned on the tubing for the purpose of making another cut.
