Title: Heat-shrink end cover prodn. - by applying heat-activated adhesive inside heat-shrink tube, inserting plug into one end and heating to fuse adhesive and shrink it
IPC: H02G15/04
Filed: 1990-09-11
Abstract: Heat-shrink end caps produced to seal off the ends of substrates, using a heat-reactive adhesive coating on the inside surface of the cap. In the process a plug is inserted into the end of an expanded heat-shrink tube of any desired length, and that end of the tube is heated so as to shrink the tube firmly round the plug. The plug is pref. made of a plastic or elastic material. More specifically, the heat-shrink tube (1) with its coating of adhesives (2) of e.g. even a series of adhesive strips arranged longitudinally on the i.d. of the tube (1), alternatively, the tubing can be coated e.g. spirally by a revolving extruder head. The plug (3) is inserted into the end. Where that end (12) is subjected to focussed heating it shrinks round the plug (3) and the melted adhesive coating (2) flows to give a good bond to the plug by applying the pressure of the shrinkage effect. The adhesive is activated only at the heated area. it can be utilised elsewhere at a later stage. ADVANTAGE - The method dispenses with any need to apply an adhesive afterwards. A range of cross-section sizes of substrate can be covered with a single size of cap. (4pp Dwg.No.1/2)

Title: Automatic sliver supply
Inventor: KRIEGLER ALBERT
IPC: B65H67/04
Filed: 1990-11-08
Abstract: To lay a sliver automatically at the feed of a textile machine, eg drawing unit, spinner, knitter, the end of the sliver is brought to a defined holding position to be taken as the start of the sliver for transfer to the feed machanism. The end of the sliver is first brought to a ready position before moving to the holding position. The ready or holding positions can be at the supply can in the centre or at its circumference. The sliver end in the can or extending downwards has a min length of 100 mm and a max length of 200 mm. When the can is being filled, the last section of sliver is taken as the start and placed in a ready position so that it is correctly placed when the can is moved into the holding position for the required feed unit. The sliver movement into the can, on filling, is ended after the can has been moved clear of the filling station to be laid at the trailing side of the can to be secured in place during the can movement to the textile machine. The can is not allowed to rotate until it is at the holding position. At the ready and/or holding positions, the start of the sliver is laid on a defined path in a preset length to be clamped near the start end while the sliver has axial movement at the trailing end of the path.  The sliver is positioned above the textile machine feed  from the can in the holding position, and clear of any other slivers. The start of the sliver is prepd and is given a partic starting length while any section which varies from nominal thickness is severed, or the length is achieved by drawing the sliver apart.
