Patent DE-2708806-A1 (DE)
Title: Fabric section separation - has vibration to pull separated section clear and tear the melted holding threads
Inventor: EHEMANN KURT
IPC: D06H7/22
Filed: 1977-03-01
Abstract: In sepg. fabric sections from each other, where they are held together by threads which melt, heat is applied to melt these threads to allow accelerated rollers to pull the separate section out while slower rollers tend to hold the unsepd. section back. After heat has been applied to melt the holding threads, vibration is applied to the material so that the sepd. section is thrown upwards to tear the molten threads. The process gives a clean sepn. of longer fabric sections, so that no finishing is required for the edges.

Title: Jacquard pattern operation - using pneumatic pressure on pattern card for selective operation on hydraulic pistons
Inventor: BOCK LOTHAR DIPL ING
IPC: D03C3/22
Filed: 1978-01-18
Abstract: The pneumo-hydraulic system to carry the required movements from the data on the pattern programme of a Jacquard machine generates a pressure cushion in a pneumatic pressure unit which is fed through the control drillings to a programme punched card. The perforations in the card allow pressure to pass through at only certain points, giving selective operation of a hydraulic system according to the patterning. The exerted pressure acts on pistons so that they act on volumes of hydraulic oil as pressure columns, and displace cylinders in a movement which activates the selected patterning components. The system gives a direct action on the operating components according to the pattern, there are no intermediate stages in the operation or linkages so that operating noise levels are low, and the system requires little maintenance and servicing.
