Abstract: An apparatus for controlling operation of a processing machine has a computer preferably with a computer aided design program configurable to model a kinematic velocity profile of a point of interest on a machine to be controlled. A graphical user interface on the computer enables an operator to select desired velocity points for a motor drive controlling motion of the point on the machine. A curve fit is applied to the velocity points to realize a desired velocity profile for the motor drive and the point on the machine. The desired velocity profile is then integrated and scaled in order to obtain a scaled velocity profile that realizes an actual, or target displacement of the point as dictated by operation of the machine. By controlling operation of elements of a machine with velocity profiles, coordination of associated elements and points on the machine can be visualized by an operator selecting the velocity points for each drive of the machine. A method for implementing same is also disclosed.

Abstract: In accordance with one aspect of this invention an improved trim press is taught for use in separating molded articles from a web of material. The trim press includes a frame, a drive motor carried by the frame, a first platen carried by the frame, and a second platen carried by the frame and configured to be moved in reciprocation relative to the first platen. A first flywheel assembly is provided on the trim press having a weight with an eccentric mass, the weight being driven in rotation by the motor and coupled to drive the second platen via at least one kinematic linkage. The trim press also includes a second flywheel assembly having a weight with an eccentric mass, the weight being driven in rotation by the motor and coupled to drive the second platen via at least one kinematic linkage.
