ABSTRACT:
A blade setting tool assembly for clamping a plurality of heat seal and cutting blades within a blade retaining channel of a three blade seal bar is disclosed. The blade setting tool assembly includes a blade positioning block having an upwardly directed blade positioining slot extending along its length to receive the exposed blade edges. A pair of mounting straps fixed to the blade positioning block extend upwardly along opposite sides of the block and include upper ends terminating above the height of the blade seal bar. The strap upper ends are each formed with a slot open to one of the vertical edges thereof to receive opposite end portions of an eccentric roller extending between the upper ends. Rotation of the roller causes an eccentric or throw portion thereof to firmly press against the top surface of the blade seal bar to transmit clamping pressure which firmly seats the blades within the channel with the exposed blade edges pressed against the blade positioning slot bottom into a desired profile relationship. Existing screws are then used to tighten the clamping bar portions of the blade seal bar together to firmly clamp the blades within the blade retaining channel. A method of properly positioning and clamping plural blades along their entire length with the blade setting tool assembly of the invention is also enclosed.
