Abstract
An apparatus for making accurate cuts in thermoformed articles projecting vertically above a generally planar sheet of thermoformable material includes a base plate having a lower surface, at least one pair of knives being mounted to the lower surface of the base plate to depend therefrom and being capable of limited movement, each knife having a cutting portion and a guiding portion, the guiding portion of each knife being angled relative to the longitudinal axis of each knife and being divergent from the adjacent knife. Each pair of knives is disposed on the base plate, and the base plate is disposed relative to the sheet of thermoformable material so that thermoformed articles advanced toward the apparatus will engage the guiding portions of the knives and cause the knives to slidingly contact sides of the articles, and upon lowering the base plate toward the sheet, the cutting portions of the knives are positioned to create score lines in the sheet which are substantially flush with the sides of the articles.
