The glass processing apparatus can also comprise a second processing apparatus positioned to receive the second protective layer and produce a second processed product different than the first processed product, from the second protective layer. In some embodiments, methods for processing glass with a glass processing apparatus.

An apparatus for melting and dispensing thermoplastic material is provided that includes an un-heated hopper having an inlet for receiving particles of a thermoplastic material and an outlet for discharging the particles and a heated manifold including at least one cavity formed therein and having an inlet and an outlet the inlet communicating with the outlet of the hopper for receipt of the particles from the hopper. The hopper is disposed external of the heated manifold. The heated manifold is effective for melting the particles into molten thermoplastic material therein. The apparatus further includes a pump having an inlet in fluid communication with the cavity. An outlet of the pump is in fluid communication with an inlet of a dispenser and an outlet of the dispenser is effective for dispensing the molten thermoplastic material therethrough.

The invention relates to a method and to an assembly for recycling plastic materials, comprising the following processing steps: a) reprocessing the raw material, wherein the material, if necessary, is comminuted and brought into a fluid-like form and heated and permanently mixed, while preserving the lumpiness and pourability thereof, and optionally the viscosity thereof is increased and/or it is degassed, softened, dried and/or crystallized; b) melting the reprocessed material, at least so much that filtration is possible; c) filtering the melt in order to remove impurities; d) homogenizing the filtered melt; e) degassing the homogenized melt; and f) discharging and/or subsequently processing the melt, such as by granulation, blown film processing, with said processing steps being carried out consecutively in the order listed.

Systems, feeder devices and methods for moving particulate hot melt adhesive from an adhesive supply to an adhesive melter. A feeder device includes a body having an inlet and an outlet, and an interior communicating with the inlet and the outlet. The inlet is configured to receive particulate hot melt adhesive from an outlet of the adhesive supply, and the outlet is configured to provide particulate hot melt adhesive to an inlet of the adhesive melter. The feeder device further includes a mechanical agitator positioned in the interior for urging the particulate hot melt adhesive in a flow direction toward the outlet.

A fluid delivery device is provided. The fluid delivery device includes a melter having a loading chamber and a hopper disposed in communication with the loading chamber, the loading chamber having one or more heating elements. The hopper includes a second heating element. The melter also includes a container handling system for lifting a container a predetermined height and moving the container from a position remote of the melter to a position within the loading chamber. The container includes contents stored within. The heating elements heat the contents so that the contents may be received in the hopper. The hopper may continue to heat the contents to provide a fluid. The fluid may be discharged from the hopper by way of a pump assembly. A pressure of fluid may be regulated at the pump assembly.

A melter for preparing a molten medium, in particular for preparing a molten adhesive, has a melting tank that has a melting chamber for receiving and melting a medium to be melted. The melter has a heating device for heating the melting chamber. The melting chamber has an upper chamber section and a lower chamber section. The melting tank has a dispensing opening that can be fluidly connected to a delivery device for delivering the molten medium. The melting tank further has a drain opening. The dispensing opening and the drain opening open into the lower chamber section. The melter further has a closure body for closing the drain opening. In a closed position, the closure body closes the drain opening and an end section of the closure body projects into the lower chamber section.

A compostable material and methods of forming the same are described. The compostable material includes about 90% to about 99% by weight of a compostable polymeric material and a nucleating agent. The compostable material has a degree of crystallinity of about 5% to about 45%.

A method of producing thermoplastic resin composite material in which a main base material containing thermoplastic resin and a sheet-like shaped auxiliary base material are integrally molded and are made into composite material. The production method includes the steps of: heating the auxiliary base material (step S1); disposing the heated auxiliary base material in a mold (step S2); disposing the main base material in the mold via the auxiliary base material (step S3); closing the mold, and pressing together and integrally molding the auxiliary base material and the main base material (step S4); and taking out the integrally-molded thermoplastic resin composite material from the mold.

A thermoplastic extrusion vehicle for continuous processing of thermoplastic material used for applying lines and stripes to a roadway. Heated oil from a burner is directed to a common reservoir having a section for oil distributed to the extremities of the vehicle and a main section for heating of melting kettles; the common reservoir having a divider wall capable of maintaining two different temperatures within the reservoir. A programmable logic controller displays and records the mil thickness of lines that is calculated according to the volume of material consumed at the rate of application based upon the speed of the vehicle.
