Abstract: A horizontal injection molding machine includes two platens, of which one can be a fixed or a moving platen and the other a moving platen, with the platens moving on horizontal columns, and a mold half carrier which is rotatably supported by a turntable and carries mold halves for injection molding tools. A yoke extends between the upper columns for movement along the upper columns. The mold half carrier has on its top side a pivot pin which engages in an opening of the yoke. This arrangement eliminates or at least reduces forces on the columns due to weight and torques.

Abstract: A clamp-type locking mechanism has a driven element rotatably arranged with respect to a holding element and having ramps which together with a track of the holding element define clamping gaps for receiving spring-loaded clamp rollers. An adjustment element is swingable to a limited extent with respect to the driven element and provided for rotation in unison with the driven element, with the adjustment element having engagement members for moving the clamp rollers out of their clamping gaps. Located between the driven element and the holding element is a friction device for transmitting a friction moment. In order to maintain a correct friction moment during wear of the friction device, a spring mechanism is provided by which the friction device is biased with its friction surface against the holding element.

Abstract: A winch, includes a housing which receives therein a rotatable rope drum moveable in a longitudinal direction between two end positions through operation of a gas-actuated piston. A spindle, mounted in fixed rotative engagement to the rope drum and extending in coaxial relationship thereto, carries a nut which is securely fixed to the housing for guiding the spindle in the longitudinal direction. Arranged coaxially between the piston and the rope drum is a pivot bearing which includes two bearing rings arranged side-by-side in a direction of a rotation axis of the pivot bearing, whereby, during operation, an end face of the rope drum rests upon one of the bearing rings, and the piston rests on the other one of the bearing rings.
