Abstract: An apparatus for manufacturing a plastic molded part. A plasticized plastic composition is fed to the open mold cavity defined between a lower and an upper mold half. At least one web and perhaps two webs of decorative material to be applied to the molded part extend across the mold cavity. The closing of the mold halves presses the plastic composition against the web or webs. There is at least one two-part clamping frame for resiliently holding the web of decorative material by clamping it outside the mold cavity, so that the web can slip with respect to the composition as the mold halves move together. One clamping frame half is developed with an immersion edge which defines a side edge of the mold cavity and with a cutting plane spaced from the immersion edge a distance sufficient that the frame half also serves as an ejector for the molded part from the mold cavity as the mold halves open apart.

Abstract: A process for the production of a cover unit with a seal for vehicle roofs in which a cover part, such as a glass cover part, a cover support and a profile part, having a replacement seal receptacle are inserted in a mold having an upper part and a lower part. The profile part is spaced from the cover part and the support leaving edge gaps which are filled by introducing an elastomer therein to connect this assembly to a cover unit. The profile part is attached and aligned, in a preferred embodiment, by attaching projections on the upper part and/or lower part of the mold depending on its position in the production of the cover unit. A peripheral seal can be molded on the profile part.This peripheral seal can be removed from the profile part, so that the seal receptacle of the profile part can be used to insert a replacement seal.

Abstract: A hollow injected shaped body of synthetic plastic is produced by injecting a predetermined quantity of a synthetic plastic melt into a multi-part mold, and forming the melt to the shaped body by a gas under pressure. After bringing the synthetic plastic melt into the mold cavity, the gas is injected into the synthetic plastic melt, then after overcoming the shaped body wall it flows into an overflow chamber from it into a gas circulation system so that during the forming of the melt a hollow formed in the shaped body is continuously supplied with the gas until rigidification of the shaped body.

Abstract: A winter sport device includes a pair of elongated parallel skids, a user support upwardly spaced from the skids, and an arrangement mounting the support on the skids for tilting movement of the support about a first axis parallel to the elongation of the skids and for simultaneously converting the tilting movement into a corresponding tilting movement of the skids about a second axis paralleling the first axis.
