Abstract
A precut die apparatus arranged and adapted for use in a thermoform-trimming method and system to produce plastic molded articles, and to the method and system in which the apparatus is employed. The precut apparatus is positioned, in the method and system, between the form press and the trim station. The precut apparatus is arranged to precut, in a desired and selected manner, the thermoformed sheet material containing thermoformed articles therein, about the periphery of the thermoformed articles. The precut provides for a bridged and joining area of the sheet material to allow for slight movement and adjusting of the molded articles for precise alignment in the punch and die trim step of the thermoforming and trimming operation.
