摘要： An improvement for attaching fastener strips to other objects wherein a strip of fastener material is formed into the surface of urethane foam or the like during molding in a mold. The fastener material comprises a backing strip having an outer surface adapted to mate with the foam material during molding and a fastener strip having an outer surface comprising one-half of a fastening system such as hook and loop fastening material. The backing strip and the fastener strip are attached to one another with their respective inner surfaces in face-to-face relationship with their outer surfaces facing outward. The fastener material fits within a longitudinal groove in the mold and the backing material overlaps the groove. The invention comprises an improved apparatus including a backing strip that is wider than the fastener strip and provides exposed strips on both sides of the fastener strip. A pair of strips of polyethylene film is attached to the exposed strips only along lines adjacent the edges of the fastener strip and forms two unattached gasket strips for contacting the mold and preventing entry of the foam-forming liquid into the groove.

摘要： A mold component for forming a foamed part with a three-dimensional shape includes a magnetic block having a first face that defines a curved three-dimensional surface with a hook strip-receiving recess positioned above the magnetic block. The magnetic block is configured to be placed in a mold with a hook strip placed in the hook strip-receiving recess. The hook strip has a ferrous metal-containing component such that the magnetic block attracts and holds the hook strip with the hook strip conforming to the curved three-dimensional surface. Characteristically, the mold component is configured to be applied in a molding process to mold the three-dimensional shape in the foamed part wherein the hook strip attaches to a trim cover.

摘要： A three-dimensional mesh-like body is disposed on a molding face of a lower mold onto which a liquid raw material of flexible foam is poured. An upper mold is laid over the lower mold to form a cavity, a projection projected on the upper mold toward the cavity is contacted with the three-dimensional mesh-like body, and the three-dimensional mesh-like body is fixed. The three-dimensional mesh-like body is attached and fixed to a front surface of a pad main body, so that the three-dimensional mesh-like body can be prevented from being displaced with respect to the pad main body. Moreover, the position of the three-dimensional mesh-like body can be prevented from being displaced in the process of foaming the liquid raw material because of the projection, and a vent hole can be formed on the pad main body. As a result, a sweaty feeling can be suppressed.

摘要： Method for producing an SMC multi-layer component in a production process. The component has a sandwich structure. At least one foam material layer (3) is embedded between two SMC cover layers (2, 2′). An insert layer arrangement comprising at least one first and one second SMC semifinished product cover layer (2, 2′) is positioned in a press mold comprising a punch (1) and a die (1′). A first and a second SMC semifinished product cover layers (2, 2′) are shaped into two SMC cover layers (2, 2′) by applying pressure to the layer arrangement. Curing of the first and the second SMC semifinished product cover layers (2, 2′) is initiated. The punch (1) and the die (1′) are moved away from each other, until the distance provided therebetween corresponds to a thickness of the SMC multi-layer component to be produced. A foaming process of a material (3′) that can be foamed, which is provided between the two SMC cover layers (2, 2′) is initiated, producing the foam material layer (3). After the foaming has ended, the SMC multi-layer component is removed from the press mold.
