Title: Method for the continuous direct coating of chipboard and apparatus for preparing the surface of the chipboard
IPC: B27N7/00
Filed: 1993-04-01
Abstract: The invention relates to an apparatus which is particularly suitable for preparing the surface of a continuously produced chipboard for direct coating with decorative foils or papers, and a method which uses this apparatus for continuous in-line direct coating. The apparatus substantially consists of a thin support on which diamond powder is galvanically bound, and which is pressed by compressed air against the chipboard. At the same time, the support is oscillatingly moved transversely to the direction of advance of the chipboards. The result is a minimal removal of material. The method comprises arranging the apparatus described above directly behind the outlet of the twin-belt press producing the chipboard, so that the surface of the boards is ground while they are still hot. This is immediately followed by an unreeling station for the decorative foils or papers and a twin-belt press for pressing together the chipboard and decoration.

Title: Tensioner for belt or chain pulleys esp. for use in motor vehicles
Inventor: WILHELM MANFRED DIPL ING
IPC: F16H7/08
Filed: 1994-03-04
Abstract: The tensioner has a one-piece guide plate (2) and support (3) forming a hollow hub, with an end plate (18) and a bolt for fixing the position of the rotation centre of the tensioning pulley (5) via an eccentric (11).

Patent DE-4417807-A1 (DE)
Title: Image-recording device
Inventor: TAKAHASHI MITSURU
IPC: G03G15/01
Filed: 1994-05-20
Abstract: An image-recording device has an intermediate transfer belt which can be rotated or moved to and fro. Before the belt is rotated or moved backwards and forwards in order to produce a composite toner image, it is set in motion in the direction which is opposite to the image-producing direction. As a result, both during the forward and also during the backward movement, the belt has essentially the same deviation. The device consequently ensures images of high quality by preventing individual toner images from not coinciding due to the deviation of the belt.

Abstract: A covering rail (20) fits over the L-section base rail (10), and has a portion (30) bearing against the flooring (B). Two flanges (24, 26) extend downwards from this rail, and accommodate the vertical flange (14) on the base rail between them. Holding devices such as screws (40) secure the rails to each other via their flanges. The beam thickness of the vertical base-rail flange (14) is at the most double that of its horizontal one (12), but less than the width of the gap between the flanges on the covering rail. A channel (42) is thus formed between the flanges, and in which the screws etc. engage. One of the covering rail flanges can bear flat against the base-rail one, the inserted screws clamping them together. The inner face of the base-rail flange can contain parallel lengthwise grooves of the same pitch as the screw threads.
