Systems, devices, and methods are described for extruding materials. In certain embodiments, one or more hollow billets are loaded onto an elongate mandrel bar and transported along the mandrel bar to a rotating die. The billets are transported through fluid clamps, which engage the mandrel bar and provide cooling fluid to the mandrel bar tip, and through mandrel grips, which engage the mandrel bar and prevent the mandrel bar from rotating. One or more press-rams advance the billets through a centering insert and into the rotating die. A quench assembly is provided at an extrusion end of the extrusion press to quench the extruded material. A programmable logic controller may be provided to control, at least in part, operations of the extrusion press system.

The machine comprises a rotary feeder configured to receive the first tubular body and the second tubular body; wherein the first tubular body and the second tubular body are secured to one another separately in a single coaxial direction in the rotary feeder; and wherein the two tubular bodies make up separators of the pallets. The machine also comprises a robotic arm configured to transfer the two tubular bodies in pairs from the rotary feeder to an area above a transport table on which a first base of the pallet rests; so that one of the end portions of the second tubular body fits into an opening of the first base; wherein the robotic arm places the first tubular body around the second tubular body.

A method is shown for fusing sections of thermoplastic pipe together to construct continuous pipelines. A pipe loader arm is provided which can be attached to the mobile sub-frame of any number of commercially available fusion machines. The pipe loader arm scoops up and loads a new section of thermoplastic pipe to be fused into the fusion machine by feeding the pipe in an axial direction, rather than lifting the new section of pipe with a crane and vertically feeding it into the fusion machine. An exit-end support can be used to gradually lower the growing pipeline to the ground after the fusion step. The method described herein greatly reduces the time and increases the ease in which sections of pipe are fused to grow pipelines, while additionally making the process safer and protecting newly-made pipe joints from rough handling.

An apparatus is provided for forming a composite laminate. The apparatus comprises a mandrel having a surface on which the composite laminate can be formed. The apparatus further comprises an application surface and a conveyor configured to move a composite material piece that has been cut to a desired shape to the application surface. The apparatus also comprises an actuating mechanism for, when actuated, lifting the application surface upward towards the mandrel to apply the composite material piece to the surface of the mandrel to form at least a portion of the composite laminate on the surface of the mandrel.

Packaging systems with a rotatable table top held by a rotatable column, a plurality of circumferentially spaced apart clipper assemblies held at respective clipper stations provided by the rotatable table top, plurality of spaced apart pneumatic valves under the table top in fluid communication with the clipper assemblies, and at least one of: (a) a clipper reset cam assembly held under the rotatable table top with first and second reset cams cam that selectively automatically engage the pneumatic valves as the table rotates; and (b) a clipper trigger cam assembly held under the rotatable table top circumferentially spaced apart from the clipper reset cam assembly with first and second trigger cams that selectively automatically engage the pneumatic valves as the table rotates.

A dosing device for dosing plastic material, comprising an extrusion head that has a dispensing opening commonly called a die and a punch extending into the dispensing opening, coaxially thereto, for continuously extruding a plastic material in the form of a tubular or annular body, and a cutter for separating a dose of said plastic material in the form of a tubular or annular section. The cutter includes at least two elements having at least one cutting edge extending on either side of the dispensing opening and secured to a driver for symmetrically moving the at least two elements in relation to a longitudinal axis of the extruded tubular body until the tubular body is severed by said at least two elements in order to form a dose.

The invention relates generally to injection mold components, and more specifically an injection mold material flow channel configured with at least one fin projecting inwardly from an inner surface of the melt channel. An injection molding insert may be made for insertion within a flow path of an injection mold components and include a substantially tubular body defining a channel; and at least one fin projecting inwardly from an inner surface of the channel.

A guide mandrel is provided for machine insertion of plastic or rubber tubes into a shaping mold. The guide mandrel includes a rigid rear portion and a flexible front end portion, the flexible front end portion including an elastic front end member. A rear end of the guide mandrel is configured for mounting of the guide mandrel in a device for automatic insertion of the plastic or rubber tubes into a shaping mold. A device for automatic insertion of straight plastic or rubber tubes into a shaping mold using the guide mandrel is also provided.
