Abstract: The present invention relates to a vehicle test bench for calibrating and/or testing systems of a vehicle which comprise at least one camera. The vehicle test bench has a target position for the vehicle. At least one surface that reproduces an image display and/or shows an image display is assigned to the cameras of systems to be tested. A plurality of elements that absorb stray light are provided, which elements each consist of a wall-like boundary of the vehicle test bench, which reduces penetration of light into the vehicle test bench. A plurality of wall-like boundaries results in lateral delimitation of the vehicle test bench on all sides.

Abstract: The invention relates to a method for repairing a printing roller having a roller base body made (10) of plastic or a plastic compound material. Into the two end regions (14) of the roller base body, bearing support members (16) are inserted, said bearing support members being connected to the roller base body (10) by bonding. Due to the occurrence of high stresses during the operation of the printing roller, inner surfaces (24) of the bearing support members (16) may be damaged. The damaged bearing support members (16) will be milled on their inner surfaces (24). Then, a respective sleeve (32,44) is inserted into the bearing support members (16). The inner surfaces (36) of the sleeves (32,44) serve for taking up outer bearing rings (26) of the roller bearings supporting the printing roller. The invention further relates to a printing roller with inserted sleeve (32,44).
