Title: Printing machine sheet cutting and folding mechanism - has collector roller with perforator and cutting roller with single and double cutters
Inventor: JESCHKE WILLI
IPC: B41F13/64
Filed: 1980-09-03
Abstract: The sheet cutting and folding system at the delivery end of a printing machine includes a collector cylinder (5) and cutting cylinder (6) underneath a funnel through which the printed web (1) passes. The web is pulled by a pair of rollers (4) and guided around the collector cylinder which has a perforator (10) projecting from its surface. The cutting cylinder which rotates against it, has a cutting blade (14) diametrically opposite a double cutting blade (13). The double blade can cut a strip which has been perforated from the cut sheet, which is afterwards removed before the folded sheet is released.. The mechanism is for cutting double pages forming four sides of e.g. brochures. The system can include an adhesive applicator which is operated cyclically so that multiple page sections can be built up. The perforator enables a collector roller with a hardened surface to be used, without being out of balance so that oscillation is not generated. The position of the cut is accurately maintained.

Inventor: THOLEN PAUL
IPC: F01P7/10
Filed: 1980-02-27
Abstract: An air-cooled internal combustion engine equipped with a hydronamic retarder is combined with a cooling system for the hydronamic retarder fluid. The system comprises a cooling air shroud for directing cooling air past the engine in cooling relationship thereto and a cooling air fan for pushing air through the shroud. The system further includes a retarder oil cooler located upstream from the fan remote from the engine and circuit means are provided for circulating retarder oil through the cooler. Exhaust valves are provided in the shroud and are positioned for diverting at least a portion of the cooling air flow from the shroud when the valves are open. Thus, the overall pressure loss of the system may be decreased and the total flow of cool air through the cooler may correspondingly be increased to increase the cooling efficiency in the cooler.
