An extruder has a valve assembly configured to move pins to open and close the nozzles in a multi-nozzle extruder head independently. The pins of the valve assembly that are driven by actuators into and out of engagement with nozzles in the extruder head are positioned within sleeves that extend between the valve assembly and the extruder head. A gap is provided between the extruder head and the end of the sleeves proximate the extruder head to enable thermoplastic material leaking from the extruder that contacts the pins to remain in a melted or plastic state so the thermoplastic material does not interfere with the movement of the pins.

The invention relates to a belt roller system for applying a surface structure in a floor panel or wall panel, said system comprising at least one upper endless belt and at least one lower endless belt, wherein each belt is rotatable around at least two pulleys, and at least one drive unit for rotating the upper endless belt and/or the lower endless belt. At least part of the upper endless belt comprises a surface structure and/or at least part of the lower endless belt comprises a surface structure. The upper endless belt and the lower endless belt are positioned substantially parallel to each other such that a panel can be transported between the upper endless belt and the lower endless belt such that the surface structure of the upper endless belt and/or the surface structure of the lower endless belt is transferred into the panel upon transport of the panel between said upper endless belt and said lower endless belt.

A system for manufacturing a composite part including a conductive flexible facesheet and an automated tape layup (ATL) machine for laying up composite tape onto the facesheet that is laid flat on a flat surface. The system also includes a curved tooling surface for transferring the facesheet with the composite material thereon to the curved tooling surface for attachment of substructures and curing into the composite part. System may also include insulation placed below the facesheet and insulation placed above the composite material, as well as a source of electricity and heat for heating the conductive facesheet to cure, melt, or fuse the composite tape and substructures without heating the tooling surface and other tooling used in the composite curing process. Heating of the facesheet may be performed using joule heat provided by a single turn transformer inducing current to conductive wires attached at opposing ends to the facesheet.

High-frequency welding method for welding an accessory to a substrate by high-frequency welding machinery which includes a female mold, having a cavity formed by a profile having substantially the same shape and dimensions as the accessory, and a male mold, having a relief formed by a profile having substantially the same shape and dimensions as the accessory. The method includes: mounting the female mold on a movable upper plate of the machinery and the male mold on a fixed lower plate of the machinery, or vice versa, such that the profile of the cavity is aligned in a closure direction of the molds with the profile of the relief. The method further includes: positioning the accessory on the relief or in the cavity; positioning the substrate above the accessory; moving the upper plate towards the lower plate; supplying high-frequency welding energy to the upper plate and/or to the lower plate.
