A modular plastic pipe formation apparatus, wherein at least two components of the pipe formation apparatus are disposed with respect to at least one or more respective modules.

A system for manufacturing a thermoplastic prepreg includes a double belt mechanism that is configured to compress a fiber mat, web, or mesh that is passed through the double belt mechanism, a resin applicator that is configured to apply monomers or oligomers to the fiber mat, web, or mesh, and a curing oven that is configured to effect polymerization of the monomers or oligomers and thereby form the thermoplastic polymer as the fiber mat, web, or mesh is moved through the curing oven. The double belt mechanism compresses the fiber mat, web, or mesh and the applied monomers or oligomers as the fiber mat, web, or mesh is passed through the curing oven so that the monomers or oligomers fully saturate the fiber mat, web, or mesh. Upon polymerization of the monomers or oligomers, the fiber mat, web, or mesh is fully impregnated with the thermoplastic polymer.

A method for the production control of an extruded plastic product with the following steps: recording at a first measuring point a first actual temperature of a measuring area provided on the plastic product, recording a second actual temperature of the measuring area at a second measuring point which is arranged at a distance from the first measuring point in a direction of extrusion of the plastic product, determining a setpoint temperature of the measuring area at the second measuring point, and outputting information on whether the second actual temperature is inside or outside a prescribed tolerance range of the setpoint temperature.

A rubber member molding method for molding a rubber member having a belt shape by attaching rubber discharged from a die to a molding surface while relatively moving the die and the molding surface in a direction along the molding surface, the rubber member molding method includes setting, as an abutting position, a position where a first one of the die and the molding surface is moved in a direction of moving closer to a second one and abuts on the second one before start of molding, and setting, as a molding start position, a position where the first one is moved from the abutting position in a direction of moving away from the second one by a desired thickness of a rubber member at the start of molding.

The invention relates to a device for producing plastic pipe from a molten plastic tube. The device comprises a injection head for connection to an extruder for the extrusion of the molten plastic tube and several molding jaws in each case having a molding surface for the molding of the extruded molten plastic tube, which, for molding the extruded molten plastic tube, are arranged, in each case in pairs, guided by means of a drive device along a molding path in the production direction of the extruded molten plastic tube. The molding surface in each case partially encircles a receiving space for receiving the molten plastic tube. According to the invention, at least one of the molding jaws has a sensor device which comprises at least one sensor with a data-capturing sensor head, which is arranged such that its capture area comprises an area of the molding surface and/or an area of the receiving space.

This invention relates to a roofing, cladding, or siding module, comprising an underlapping region extending from a head edge of the module and an exposed region extending from a foot edge of the module. The length of the foot edge defining the length of the module. The underlapping region is adapted to be substantially covered by the exposed region of an adjacent or overlapping module when installed on a building surface. The module is formed of at least one layer of extruded material. The layer so formed comprises at least 40% w/w filler and/or reinforcement, and one or more polymer(s).

This invention provides for a component forming a part of a breathing tube, or forming the breathing tube, for example as a part of a breathing circuit for respiratory therapy. The component comprising a tubular body having a foamed wall. The foamed wall can be formed from extrusion of a single extrudate. The foamed wall is of a sufficient minimum optical transparency such that, in use, there is enabled the visual detection of a liquid (or condensate that may have formed) within the tubular body.

A process produces an electrical line which extends in the longitudinal direction and the line has a line core and an outer shell. In a continuous shaping process, individual shell portions of the outer shell are formed successively by surrounding the line core with a curable plastic substance. In at least one portion, the outer shell is produced having a cross-sectional geometry which can be varied in the longitudinal direction of the line.

Subject matter of the present invention is a method of applying coating layers (9) to a substrate (1, 11, 21, 31), wherein the substrate (1, 11, 21, 31) is drawn through a coating chamber (2) containing a pressurized coating agent (3) being liquefied or softened by means of a thermal exposure, wherein the substrate (1, 11, 21, 31) is drawn through a drawing tool (8), wherein the coating agent (3) serves as a lubricant between the drawing tool (8) and a surface of the substrate (8) and wherein at the same time the coating layer (9) is applied to the surface of the substrate (8). Subject matter of the invention is also a corresponding apparatus for applying a coating layer (9) to a substrate (1, 11, 21, 31). By means of the invention coating layers can be applied to a substrate in an efficient and economical way.

In the manufacture of double-walled corrugated extruded pipe it is desirable to form an integral connecting cuff that is of a single wall thickness and typically of a large diameter. The mold blocks and process parameters for forming of the cuff as part of an otherwise double-walled pipe requires a transition as the cuff moves past the die outlets. The present invention allows for accurate sensing and control of air pressure and temperature as the cuff moves past the die outlets. Improvements in both the die tooling and the method of manufacture are disclosed.
