Abstract: A fastener for fastening a component having a mounting hole has an essentially U-shaped clamping region that at least partially grips around the component and has two opposing legs that are connected together as a single piece by a connecting region. The legs are provided with through holes that serve to accommodate a pin or stud that passes through the mounting hole of the component. A nut is attached to a first leg on the side facing away from the second leg such that the connection between the first leg and the nut can be released by a separating force acting on the nut.

Abstract: Device (1) for manufacturing plastics films from a plastics melt and having a roll frame (3) in which at least one chill roll (2) is rotatably mounted, an exchangeable part of the device (1), for pressing the plastics melt against the chill roll (2) mounted in the roll frame (3) and for chilling the same, being attachable to the roll frame (3) and for the manufacture of plastics films with different characteristics, various modules (10) being provided as the exchangeable part, so that the device (1) allows different plastics films to be made by means of different manufacturing methods.

Abstract: Device (1) for use in a roll frame (10) for the manufacture of a plastics film, having a continuous band (2), looped around at least two deflection rolls (3, 3′), for pressing the plastics film against a roll (9) of the roll frame (10), the two deflection rolls (3) being rotatably mounted on both sides in lateral bearing devices (5, 5′) and fastening means are provided for fixing the deflection rolls (3, 3′) in a bearing device (5) and the other bearing device (5′) is pivotably mounted for the exchange of the continuous band (2); and a process for changing a continuous band (2) for pressing a plastics film against a roll (9) and for cooling the same, which is looped at least around two deflection rolls (3) rotatably mounted in lateral bearing devices (5, 5′), the deflection rolls (3, 3′) being fixed in a bearing device (5). Fastening means of the other bearing device (5′) are released and the other bearing device (5′) is pivoted.
