The present invention discloses a system and a method for manufacturing fittings and connections for biaxially-oriented plastic tubes in an integral way from straight preformed tubes, with the possibility of adjusting and distributing the thicknesses as well as adjusting the specific stretching in the different areas of the fittings, allowing them to be reinforced or optimized during the method itself and without causing an increase in the production time or an increase in the raw material used, such that it allows for the manufacture of fittings of different geometric shapes (curves, tapers, couplers, branches, etc.)

A workstation for a film-processing packaging machine defines a film transport plane in which the packaging film can be transported. In addition, the workstation comprises an electrically operable heating assembly. The latter in turn comprises an electrically conductive planar resistance heating element which in a plane parallel to the film transport plane has dimensions that are greater by a factor of at least 5, preferably at least 10, than in a direction perpendicular to the film transport plane. The resistance heating element is arranged between a heating plate and a clamping plate. The disclosure also relates to a packaging machine with such a workstation and to a method for operating such a workstation.

A super absorbent polymer drying apparatus is disclosed. The super absorbent polymer drying apparatus is a drying apparatus equipped with a conveyor for drying the super absorbent polymer, and may include: a conveyor for transferring the super absorbent polymer; and a hot air supply part for supplying dry hot air to the conveyor, wherein the conveyor may include a plurality of conveyor beds connected to each other in a bent state, a link connecting part for connecting between the plurality of conveyor beds, and a driving part for driving the conveyor beds.

Disclosed are a pouch film shaping apparatus including a preheating lamp configured to preheat a metal barrier layer of a pouch film in order to increase stretching force of the pouch film and a pouch film shaping method.

A system for controlling the temperature of a film before and/or during application, the system including: a heat source for heating a film; and stretch rollers; wherein the heat source heats the film from an ambient temperature to a temperature from about 2° C. to about 40° C. above the ambient temperature, wherein the film is heated prior to or simultaneous to being stretched by the stretch rollers, and wherein the ambient temperature is below 15° C. The preheating system may be used to enhance binding and sealing properties of stretch films used for wrapping palletized products in a reduced temperature environment. Other embodiments of the preheating film system, and methods for its use, are described herein.

A method is provided for forming a near-net thermoplastic composite component includes co-spraying a mixture comprising a thermoplastic polymer material and a chopped reinforcing material deposited onto at least one region associated with a tool having a first temperature and defining a near-net component shape. The mixture and adjacent tool is heated to a second temperature while the mixture is on the tool. The first temperature is below the solidification temperature of the thermoplastic polymer material and the second temperature is above the solidification temperature. Then, the mixture is exposed to a negative pressure to promote removal of gases from the mixture and put under compressive force to densify the mixture. The thermoplastic polymer material melts and flows. The tool is cooled to the first temperature and removing the mixture to form the near-net thermoplastic composite component having randomly oriented chopped reinforcement material distributed within a thermoplastic polymer matrix.

A hopper charged with a powder material, a screw arranged below the hopper and exposed at a supply port formed at the bottom of the hopper, and a rolling element in contact with the screw at the supply port are provided. The rolling element is larger than a space between end portions of the supply port and a screw groove of the screw.

A polymer-sheathed multi-filamentary strand for use in braided covers for wiring harnesses intended for use in challenging embodiments comprises a core of glass filaments wrapped in an aramid yarn, and sheathed in a siloxane-modified polyetherimide polymer. Shielding against electromagnetic interference may also be provided.

A method for forming a composite part of a gas turbine engine. The method includes assembling the composite part of a first composite material and a second composite material. The second composite material defines an outer surface of the composite part, and is selected to be curable at a cure temperature generated by heat from operation of the engine. The first composite material is selected to have an operating temperature limit less than the cure temperature. The method includes placing the composite part within the engine so that, in use, the second composite material is cured by exposure to the heat generated from operation of the engine. The second composite material thermally shields the first composite material from the heat generated from operation of the engine. The method includes operating the engine to cure the second composite material.

A method for manufacturing a connector-integrated resin tube includes: a fitting step in which an end portion of a resin tube material including a straight tube portion is fitted into an end portion of a connector of a tubular shape; a joining step in which the end portion of the resin tube material and the end portion of the connector that have been fitted are joined by laser welding; a heating holding step in which a posture holding die including a bending processing portion for bending processing of the straight tube portion is used to hold the straight tube portion in a heated and bent state at the bending processing portion of the posture holding die; and a cooling step in which the straight tube portion is cooled.
