The invention relates to a molding composed of extruded foam, wherein at least one fiber (F) is present with a fiber region (FB2) within the molding and is surrounded by the extruded foam, while a fiber region (FB1) of the fiber (F) projects from a first side of the molding and a fiber region (FB3) of the fiber (F) projects from a second side of the molding, and the extruded foam is produced by an extrusion process comprising the following steps: I) providing a polymer melt in an extruder, II) introducing at least one blowing agent into the polymer melt provided in step I) to obtain a foamable polymer melt, III) extruding the foamable polymer melt obtained in step II) from the extruder through at least one die aperture into an area at lower pressure, with expansion of the foamable polymer melt to obtain an expanded foam, and IV) calibrating the expanded foam from step III) by conducting the expanded foam through a shaping tool to obtain the extruded foam.

A method for producing a tube, which includes: extruding a melt-fabricable fluororesin from a mold of an extruder into a form of a tube, leading the extruded melt-fabricable fluororesin to a cooling device to cool the extruded melt-fabricable fluororesin, and winding a resulting cooled tube onto a winding reel using a winding device. A gas is fed from a head end of the tube wound onto the winding reel into a hollow of the tube, the gas in the hollow is allowed to pass through a gas-introducing entrance of the mold and then through a gas-discharging hole of the mold to discharge the gas outside, thereby allowing the gas to flow along the hollow, and an internal pressure of the hollow is kept higher than atmospheric pressure and lower than 0.5 kgf/cm.sup.2.

A weatherable, low heat build-up capstock system comprising an acrylic cap, a pigment system that is IR transparent to a greater degree than existing pigment systems, an IR reflective substrate, and an extrusion system for same.

The present invention relates to a molding made from foam, wherein at least one fiber (F) is partly within the molding, i.e. is surrounded by the foam. The two ends of the respective fibers (F) that are not surrounded by the foam thus each project from one side of the corresponding molding. The foam comprises at least two mutually bonded foam segments.

A lamella block is provided for a calibrating device for calibrating an extruded profile, wherein the lamella block includes a carrier structure and a lamella structure, and wherein the lamella structure has a plurality of lamellae, which are spaced apart from each other by grooves and arranged in a longitudinal direction (L) of the carrier structure. Neighboring lamellae of the lamella block are arranged laterally offset to each other in the longitudinal direction (L). Also provided is a method for manufacturing the lamella block mentioned above, as well as a calibrating device, which includes a plurality of the lamella blocks mentioned above.

A device for cutting a preferably thick-walled, extended pipe to length, has at least one cutting tool and a receiving unit for the cutting tool. The cutting tool is radially movable in relation to the extrusion axis and is rotatable via further means about the pipe to be cut to length, in order to cut the pipe to length. The receiving unit may be connected by means of a receiving disc to a sleeve via a ring element, wherein linear guiding elements are arranged on said sleeve parallel to the extrusion axis, and wherein at least four linear guiding elements are evenly distributed around the circumference of the sleeve.

Disclosed are various embodiments of an extruded expandable barrier, and various processes and systems for manufacturing the same. Using various extrusion processes to form an extruded expandable barrier allows for a reduction in tooling costs while also allowing more flexible barrier designs. Such designs can be specifically tailored for a particular cavity or cavities to ensure that the barrier fills the cavity after expansion. In addition, design changes can occur with little to no tooling changes.

A method for using the quantity of heat output from an extrudate during a cooling operation in an extrusion process, wherein a fluid, in particular air, is guided along the extrudate and/or through the die counter to an extrusion direction, at least some of the heat from the extrudate and/or the die is transmitted to the fluid, the heated fluid is supplied from a first sub region of a process chain, comprising at least one die, a calibrating and cooling device and a take-off apparatus, via a connecting region, preferably consisting of at least one connecting pipe, to a second sub region of the process chain, comprising at least one suction apparatus. In the connecting region, an extraneous fluid can be added to the heated fluid in order to reduce the actual temperature of the heated fluid at least below a predetermined maximum value before said fluid is supplied to the second sub region of the process chain.
