Abstract: A sun visor for vehicles is formed of a sun visor body constructed of plastic foam which is stiffened by a two section stiffening wire. The sun visor is supported by a mounting housing, located at one corner of the sun visor body. The mounting housing receives a sun visor support shaft. An outer support pin which can be detachably connected to a support member of the vehicle is located longitudinally opposite of the mounting housing. The mounting housing defines a first insertion opening into which is plugged one end of one of the stiffening wires and a second insertion opening which accommodates a leaf spring which bears on the sun visor support shaft. The outer support pin and the mounting housing have additional insertion holes which enable rapid connection of the stiffening wire sections to the outer support pin and to the mounting housing by plugging of the components into one another. The two stiffening wire sections are further utilized to conduct electrical power to a sun visor lamp.

Abstract: A wind-up apparatus for forming laps comprises a first winding roller, a second winding roller, a lap bobbin tube and a plurality of, for instance four, calender rolls. The calender rolls serve for consolidating a fiber layer into a windable fiber web. Each calender roll of the predetermined number of calender rolls has a predetermined rest position and an operating position. A guide structure is provided for the calender rolls to enable the calender rolls to be movable within a given mobility range defined between the rest position and the operating position. The guide structure comprises force-producing elements for moving the calender rolls into the predetermined rest position thereof.

Abstract: A sun visor for vehicles is provided at one corner thereof with a mounting housing for connecting the sun visor to a sun visor shaft which is mounted to the vehicle. The mounting housing is embedded in the plastic foam material of the sun visor and is secured to a stiffening wire insert which extends therethrough. A first insertion opening is defined in the mounting housing for receiving the stiffening insert and a second insertion opening is provided for supporting a leaf spring and for receiving the sun visor shaft. The spring bears against the shaft to prevent unwanted rotation of the sun visor about the shaft.

Abstract: A wind-up apparatus for forming laps comprises a first winding roller, a second winding roller, a lap bobbin tube and a plurality of, for instance four, calender rolls. Each calender roll is movably mounted at each of its opposite ends by means of a spring pair receiving the calender roll. Each spring pair is fixedly connected at one end to a bearing member of the related calender roll and at its other end by means of a carrier to side walls of the wind-up apparatus. A piston of a pneumatic cylinder moves the calender rolls from a rest position, in which there is a spacing D between the calender rolls and a spacing E between the last calender roll and the first winding roller, into a working position in which the calender rolls are pressed against one another in the absence of an intervening fiber layer. The position of the calender rolls in their rest position is maintained by the spring pairs.
