Abstract
An apparatus for cutting the bottom disc used in the manufacture of disposable drinking containers. A web of foam plastic container bottom material is fed through a rotary cutting die. Discs of foam plastic material are then sequentially positioned so that they can be affixed to container sidewalls which are moving in seriatim fashion past the cutting apparatus. The direction of movement of the web of foam plastic material through the cutting apparatus is periodically reversed so that the maximum number bottom discs can be cut from the web of material. The method of moving the web of material in an intermittent flow plus the movement of the severed discs is also set forth in detail.
