Patent DE-4021590-A1 (DE)
Title: Wind off creel frame for tyre cord loom - has automatic tension regulation equipment which has extendable holding arm for threading eye
Inventor: HAUERS LEONHARD
IPC: B65H57/26
Filed: 1990-07-06
Abstract: The warp creel on a tyre cord loom has a thread tension regulator. Cross bars which hold the tension eyes, advance in the loom direction as the reel unwinds, and is reduced in diameter. The creel is arranged on a frame (1) with a series of support pillars in rows to hold the spindles on each side for the reels (2,3,4) to be mounted. Attached to the pillars are rollers in pairs, with the space between them occupied by sliding bars (6, 7) and these are joined at one end near the loom by a vertical bar (8). The winding mechanism (9, 10) is fitted to draw the series of bars (7) back or forward. This may have a controlled motor drive, by which the system becomes automatic. Cross brackets reach from the bars (7) horizontally, and above each reel on each side of the support pillar. On the brackets another smaller bar holds the threading eyelets for each reel, and one eyelet behind another, as are the reels in the creel. When the reels are full, each eyelet is above and close to the reel. As the reels unwind, the eyelets are drawn forward by the mechanism, which sustains the angle from reel to eyelet, thus keeping the tension constant. Also taken into consideration is the weight of the reel itself which changes during wind off. USE - The tension in the threading eye is altered by extending the arm on which it is held, as the thread continues to unwind. This creates a different angle of the thread to the eye, and allows for reduction in weight of the reel.

Patent DE-4201639-A1 (DE)
IPC: G01N3/56
Filed: 1992-01-22
Abstract: Simulation apparatus for testing material and lubricant properties of homokinetic joints uses test specimens (13, 15) with original geometries or parts taken from original joints. The apparatus has a holding device (11) able to be inserted in a press (60), in particular of a conventional four-ball apparatus, to hold a test ball (33) securely with pro-tension between two test specimens (13, 15) with ball race channels (13a, 15a) with channel bases intersecting at 90 DEG in plan view. The ball race channels (13a, 15a) are able to move relative to each other in two directions perpendicular to each other and to a pre-tensioning direction so that rolling and sliding movements superimposed one on the other occur between the ball and ball race channels, in a manner similar to the original joints. The high loading of the test specimens which can be achieved allows particularly short test times under conditions close to reality, at the same time with low structural expenditure. A holder (31) for specimen (15) is rotatably mounted eccentrically of a drive member (41) so that when the latter is rotated by a motor (77) the specimen (15) moves in a circular path. <IMAGE>
