Filed: 1992-09-14
Abstract: Alternate layers of bundles of hollow yarns (5) and conventional yarns (6) are arranged so that the hollow yarns are wavy or straight while the conventional yarns (6) are wavy. The two sets of yarns (5,6) cross over at several points. When the hollow yarns (5) are wavy, the wave is displaced or of greater wavelength.

Patent DE-4309735-A1 (DE)
Title: Automatic handling machine with a plurality of processing stations
Inventor: MIETHE HARALD DIPL ING
IPC: B25J9/04
Filed: 1993-03-25
Abstract: The invention relates to an automatic handling machine with a plurality of processing stations, which is used in the processing industry. In particular, it is used in those branches of industry in which piece goods have to be moved and accumulated or distributed. The basic problem is to achieve a technical improvement of automatic handling machines or palletising machines which work on the principle of rotation about a vertical axis. This problem has been solved by the use of rotary unions. The constructive incorporation of such a rotary union takes place at the interface of stationary and rotating structural elements. Its technical object is the supply and discharge of gaseous and/or liquid media as well as electrical currents. At the same time, the internal design of a rotary union makes it possible to transfer the media and currents without loss during any rotation of the part connected to the rotating structural elements. It thereby becomes possible to bring about angles of rotation of all orders of magnitude up to the extreme value of  phi  = +/- n . 360 DEG . Under these preconditions, palletising machines or automatic handling machines can be designed in control terms in such a way that the path which is the shortest in each case from one processing station to the next is covered. Wasted time is thereby eliminated and the performance of the machines is effectively increased. <IMAGE>
