Patent PT-1425155-E (PT)
Inventor: KELLER GERHARD
IPC: B29C53/52
Filed: 2002-09-09
Abstract: A method for controlling the edges ( 7, 7 ') of a foil strip guided in a shaping funnel of a device producing tubular bodies from the foil strip by an overlapping weld seam using a guide wedge, the strip being then welded. According to the invention, after welding, the method consists in using a linear infrared sensor for measuring and evaluating a temperature profile perpendicular to the overlapping weld seam. In case of variation relative to the specific real profile, a signal is automatically transmitted to rotate the shaping funnel with the guide wedge, the welding being produced by the high frequency (HF) and the temperature profile being measured directly after welding.

Abstract: PCT No. PCT/CH95/00264 Sec. 371 Date Aug. 5, 1996 Sec. 102(e) Date Aug. 5, 1996 PCT Filed Nov. 13, 1995 PCT Pub. No. WO96/19602 PCT Pub. Date Jun. 27, 1996A lever (30) is pivotably mounted about ax axis Z on a carrier journal (24) which is pivotable about an axis X and with which electromagnets (46, 48) cooperate. The lever carries a thread-receiving member (20) and is under the effect of a tension spring (42). When the thread is intercepted by the thread-receiving member during the forward rotation of the cop, there follows a deflection of the thread-receiving member, which takes place with the tension spring being tensioned at the same time and which is caused by the thread, on a path approximate to the movement of the traveller on the ring. The tensioned tension spring pivots the thread-receiving member during the paying-out of thread which occurs as a result of the subsequent reverse rotation of the cop. As a result of the intermediate blocking about one of the axes, the thread-receiving member moves on a path lying approximately in a tangential plane relative to the ring. Starting from the old traveller retained on the ring, the thread is stretched on a threading-in zone extending in this plane. During the attachment of the new traveller onto the ring, the thread is grasped on the threading-in zone and is thereby threaded into the ring.
