Abstract: A baler for baling polystyrene material which has high bulk and low weight for subsequent recycling. The baler includes a ram which provides significant penetration over repeated cycles to compress the polystyrene into a bale, which is subsequently ejected through a bale door of the baler. The baler can either be manually controlled or automatically controlled, such as by an algorithm stored in programmable logic controller. Feedback systems measure the length of travel of the ram and the pressure of the ram determine the status of baling operation, and can automatically provide for ejection of the baled material. The bale can either be manually strapped, automatically strapped, and in some events, no strapping of the bale is required. The polystyrene material is chopped by a chopper system on the baler to break the material into smaller sections for baling. The baler has been specially designed to uniformly densify and bale most poly foam materials in a high production environment.

Abstract: A baler for baling polystyrene material which has a high bulk and low weight for subsequent recycling. The baler includes a ram, to compress the material past its form memory, which provides significant penetration over repeated cycles to compress the polystyrene into a bale, which is subsequently ejected through a bale door of the baler. The baler can either be manually controlled or automatically controlled, such as by an algorithm stored in a programmable logic controller. Feedback systems measure the length of travel of the ram and the pressure of the ram to determine the status of the baling operation, and can automatically provide for ejection of the baled material. The bale can either be manually strapped, automatically strapped, or no strapping of the bale may be required. The polystyrene material is chopped by a chopper system on the baler to break the material into smaller sections for baling. The baler also includes a vertical tamper to tamp the polystyrene down into the baling chamber.

Abstract: A baler for recyclable materials and any other materials. The baler includes a power unit. An operator console on a deck at a front of a hopper, which provides for operator observation and operation through a high tech control system. Material is fed into the hopper, such as by a conveyor. A compression chamber under the hopper and a bale chamber is at a forward end of the baler for baling of the materials and subsequent discharge by an ejection ram across a bale run-out table for later disposition. A control system provides the capability of automatic control for the baler, as well as diagnostic assistance when necessary. The baler is also the primary building block for a completely automated municipal recycling facility (MRF). The baler can bale such materials as corrugated cardboard, news print, magazines, computer paper, flattened cans, round cans, plastic bottles, scrap aluminum, scrap copper, aluminum radiators, as well as any other miscellaneous materials required for baling on a real time basis.

Abstract: In an apparatus for preparing absorbent pad lined packaging trays, means sense the tail end of a liner supply that is to be discarded, determines and cuts off the length thereof, withdraws the cut off length from the line of machine operation and feeds into such line the lead position of a fresh liner supply. Other means denest a supply of flanged trays to be pad lined by at least two denesters that comprise synchronized, vertically oriented rotary bodies that during parts of a single rotation each have a bottom laterally extending plate that supports the bottom-most tray of a stack, an upper laterally extending plate that supports at tray flanges the next in line tray to be denested an a laterally extending, vertically inclined cam plate that is adapted to ride on the upper flange surface of a tray that is in the process of being denested to thereby forcibly eject same.
