Abstract: Disclosed herein is a method of preparing a molding containing a structured polysiloxane layer as outermost layer, by using a molding composition (M) to prepare a sheet, film or foil (1), engraving a structure into the surface thereof by means of a laser (2), applying a polysiloxane (PS) onto the surface thereof (3), curing the (PS) to obtain a cured (PS) layer (4), adhering at least one fiber containing material onto the cured (PS) layer obtained with at least one adhesive (A1) (5), and removing the obtained stack including the at least one fiber material adhered to the cured (PS) layer via (A1) from the laser-engraved sheet, film or foil to obtain the molding containing the cured and structured (PS) as outermost layer of the molding, the cured (PS) layer having the negative of the laser engraved structure of the sheet, film or foil (6).

Abstract: The invention relates to a process for the production of multilayer composites and to a production plant (12, 60) for this purpose. The multilayer composites comprise at least one substrate web (64, 66), at least one bonding layer, and at least one polyurethane layer which has capillaries which extend through the entire thickness of the at least one polyurethane layer. First, at least one polyurethane layer is produced in a matrix (15), with passage through at least one coating unit (26, 30) and through a plurality of heating units (24, 28, 32). The matrices (15) thus treated are then introduced (76) into an input point (74) of a transfer section (60) for substrate web (64, 66). A structured side (78) of the matrix (15) is applied onto the substrate web (64, 66) passing continuously through the transfer section (60).

Abstract: A foaming agent charging and mixing device comprises at least one mixing device and one foaming agent metering device, wherein the foaming agent charging and mixing device may be arranged between an plasticating screw and a mold. In order to improve the foaming agent charging and mixing device in a manner that the mixing with foaming agent is facilitated and at the same time a risk of obstruction of the foaming agent metering device is avoided, the foaming agent metering device is alternately opened and closed through the mixing device during operation thereof for supplying foaming agent to the plastic melting.
