Patent DE-4138652-A1 (DE)
Title: Gap measuring method for CF friction polishing machine - involves allowing water or compressed air to flow through gap between container wall and baseplate and measuring flow rate
Inventor: MOELLER FRANK
IPC: B24B31/108
Filed: 1991-11-25
Abstract: Between the container and baseplate is a gap (3) whose breadth can be adjusted. Below the baseplate is a bottom chamber (4) connecting to the container space (5) by way of the gap. A test medium, water or compressed air, is caused to flow through at least part of the gap between the container and baseplate whilst the machine is empty and the baseplate at rest. The resistance and rate of flow vary with the gap, allowing the gap to be calibrated and measured. Alternatively, the bottom chamber can be filled with water and the machine tipped on its side. The time taken for the water level to drop a given distance forms the basis for measuring the gap. ADVANTAGE - Damage to machine is prevented. Method is simple and adaptable to automation.

Title: Apparatus for adjusting sheet stops
Inventor: KRATZSCH ACHIM
IPC: B65H9/04
Filed: 1993-07-31
Abstract: On known sheet feeders for gatherer-stitchers, it is characteristic to have to dismantle the sheet stops, which is time-consuming, and replace them by special stops if it is necessary to set them obliquely, for example for aligning separated, cross-folded printed sheets before they are discharged to the associated gathering chain. Owing to the arrangement of the sheet stops on a stop strip mounted so as to be pivotable and retainable in the feeder frame, according to the invention, it is possible to pivot all the sheet stops simultaneously into the intended oblique position thus obviating the need for any dismantling and assembly effort and thus having a positive effect on the production flow of the gatherer-stitcher. The apparatus for adjusting sheet stops is used on sheet feeders for gatherer-stitchers for aligning separated folded sheets before they are placed on a conveying chain.
