Abstract: The invention relates to a method by which stitch openings in the area of a seam in a plastic skin (10), in particular a PVC or TPU skin, are sealed, said PVC or TPU skin being provided for a foamed part. Foamed parts of this type are used especially as interior fitting parts, e.g. as a dashboard, in the field of automobile manufacturing. The invention further relates to a PVC or TPU skin comprising a seam of said type.

Abstract: The present invention relates to a method for producing a negative skin and a tool. Such a tool can be used, for example, in the automotive industry.

Abstract: The invention relates to a method for producing a component, said method comprising the steps of: providing a dimensionally stable carrier which comprises a first through-opening and a second through-opening; attaching the dimensionally stable carrier to a first mould half, wherein a sprue cavity is formed in the region of the first through-opening on the side of the dimensionally stable carrier facing the first mould half and an overflow chamber is formed in the region of the second through-opening; positioning a second mould half such that a cavity connecting the first through-opening and the second through-opening is formed at least in sections between the second mould half and the dimensionally stable carrier, and introducing a material into the sprue cavity.

Abstract: An infrared welding device comprising a machine base (1) having at least two workpiece supports (2) for two workpieces, the distance of which is variable, as well as at least one infrared radiator (3) fixed at a movable tool holder (4) of the machine base (1) and introducible into the gap of the workpieces formed by the distance of the workpiece supports (2). The distance of the workpiece supports (2) from each other and the relative assignment of the tool holder (4) are adjustable by a program control, wherein the workpiece supports (2) and the tool holder (4) may be assembled to form a welding module (7) transportable as closed unit (7) and may be connected with the machine base (1) by means of quick-action couplings (6).

Abstract: A sealing device for a gap between two adjacent machine parts, including at least one inflatable, elastically stretchable tube, which is fitted into a groove in the sidewall of one of the machine parts, and which, when inflated, may, be positioned against a surface of the other machine part, which borders on the gap on the side opposite the groove, at least one end of tube (2) being provided with a circumferential, turned-inward portion (6, 16) that engages its interior, into which a supporting member (5, 15) is inserted on the inside.
