Abstract: The invention relates to a method for manufacturing a moulded article from a first rubber polymer, which moulded article comprises an insert from a second rubber polymer The method comprises at least the steps of providing a vulcanizing mould with mounting means for the insert, arranging an at least partially vulcanized insert in the vulcanizing mould using the mounting means, adding the first rubber polymer to the vulcanizing mould in unvulcanized state and vulcanizing the moulded article at a suitable vulcanization temperature and subsequently removing the moulded article, with the proviso that prior to step C) at least that side of the insert which comes into contact with the first rubber polymer during step C) is provided with a reactive mixture comprising free radicals. The method is particularly suitable for the manufacture of rubber tyres and spoilers with a coloured insert.

Abstract: A method of producing a bent rod includes impregnating fibers (1) with resin (2), introducing the impregnated fibers into a flexible plastic tube (3), bringing the flexible plastic tube to a desired bent form and crosslinking the resin with the fibers to produce the rod with the desired bent shape. The flexible plastic tube is formed from a material that has a very low friction coefficient and the flexible plastic tube remains in its position after the crosslinking to permit sliding movement of the bent rod relative to an adjacent structure.

Abstract: A wing element (W) on the spoiler (S) of a motor vehicle is characterized in that the lower side (U?, U?) of the wing element is provided in a manner to substantially planar below a limit speed and therefore has a small end surface in the direction of travel of the motor vehicle, and an aerodynamic profiling of the lower side, and therefore an increased end surface, is provided above said limit speed.

Abstract: An air-conducting device for a motor vehicle has an operating element and a spoiler lip extending completely or partly over the vehicle width, by means of which operating element the spoiler lip can be displaced from a moved-in inoperative position into a moved-out operative position, and which spoiler lip comprises an elastic and extensible material. For achieving a sufficient stiffness of the spoiler lip, it is provided that the spoiler lip is made of a fiber composite material matrix which is extensible and elastic. The fiber composite material, in addition, has a first fiber group with fibers embedded in the matrix which are essentially inextensible and extend transversely to the direction of the vehicle width and the direction of the width span of the spoiler lip. The matrix further includes a second fiber group with fibers which are elastic and extend in the direction of the vehicle width.

Abstract: An air-conducting element for a motor vehicle has an operating element and a flow-conducting element extending completely or partly over the vehicle width. The flow-conducting element can be displaced by the operating element from a moved-in inoperative position into a moved-out operative position. The flow-conducting element comprises an elastic and extensible material as well as, in a area of its free end, in a duct, a bending-elastic element which extends in the transverse direction of the vehicle and is displaceably accommodated in the duct. For an improved guidance of the bending-elastic element in the duct, it is provided that—viewed in the transverse direction of the vehicle—the bending elastic element, at least in sections, is supported by at least one guiding device arranged in the area of the free end of the flow-conducting element with respect to the wall bounding the duct.

Abstract: A backrest is especially provided for passenger vehicles and is constructed basically continuously and executed as an extruded hollow profile with at least one profiled chamber. In order to attain a high absorption of force through the backrest, the direction of extrusion of the extruded profile runs in the direction of the backrest height.

Abstract: The invention enables production of polymer fibrids comprising a polyester which is injected as a low-viscosity jet into a shear field formed by liquid jets, torn apart by the liquid jets and formed into fibrids having a fibril length of from 0.1 to 5 mm by cooling, crystallization and orientation.
