Abstract
An apparatus for cutting and dispensing segments of thermoplastic material into receptacles such as crowns, particularly into those having relatively high sidewalls, includes a conveyor for conveying the crowns through a passageway at predetermined speeds, an extruder for extruding thermoplastic material through a discharge opening, a rotary knife having blades for cutting the extruded material into segments and depositing the segments into the receptacles as they are conveyed through the passage, and a drive system for rotating the blade in response to the conveying of the receptacles. The output or driven shaft of the drive system is coupled to the rotary knife and intermittently rotates 180 degrees at a time at a speed which is twice that of the input or drive shaft, thereby avoiding contact of the knife blades with the receptacle sidewalls and ensuring clean cutting of the thermoplastic material even at low speeds of closure conveyance.
