Title: Spinning frame - has computer control to link process timing to doffing mechanism
Inventor: BEYER RUDOLF DIPL ING
IPC: D01H9/04
Filed: 1991-03-01
Abstract: A ring spinning frame is controlled by a processor to produce a full cop, which is exchanged for an empty tube by a mechanism working in conjunction with a conveyor. Doffing and transport is controlled by the processor to co-ordinate with the start and end of the  cop spinning process. The frame is double sided, with a computer (CNC) and display (18) coupled to the drivers, with feedback from linear sensors, to give precise positions of the spindle bank (1) ring bank (37) as also the extension of the cop change mechanism (4). This is raised from a position below the spindles by a motor (7) to drive a shear style mechanism to lift the equipment in preparation for doffing. Then the pneumatic device (10) actuates the cop change (3) by removing a cop from the spindle (35) and placing a tube (33) from the conveyor (39), which is driven along to a suitable location for the changeover, by the motor (44). Synchronisation and control of the necessary drives is contained in the processor and programs (12). ADVANTAGE - Doffing procedure is accelerated, and esp. movements of the cop change mechanism.

Title: Stenter frame - has high pressure air circulation in enclosure for fabric
Inventor: PABST MANFRED
IPC: F26B21/00
Filed: 1992-08-26
Abstract: On a stenter frame the fast moving stretched textile fabric is subjected to a force of warm air. This may be directed from one or both sides, through orifices, and the air pressure is increased by means of an air injector jet. Typically, the fabric (1) in the roll is held across the width by grips, or a pinned plate (2) attached to the chain drive (3), which conveys the fabric along the frame. The box surrounding the fabric at the top (4) and bottom (6) has numerous orifices (5). This is part of the air circulation system, which is developed by the injector jet (7), forcing air along the passages (9,10). A flap (11) can direct the pressure into the area of most requirement. In this manner the air is forced through the fabric in direction (12) or reflected from the fabric in direction (13,14) and this current is circulated through the heat exchanger (15). A suction is developed between the heat exchanger and the injector (7). These may be incorporated in both the top and bottom box, with separate air intake and exhaust. ADVANTAGE - The ventilator system is replaced in a reduced space by a high performance drying equipment, based on the air injectors.
