Ernst -üchalke twisting mill, Langweid-Foret, via Augsburg 2 elastic lap supports for treating yarns .

The invention relates to an elastic bird carrier in the form of an overlapping with ihi * en lianteli '&. naern Luise for treating yarn. Las hay exists in that the two overlapping jacket insides in the overlapping area by means of a projection and circumferential groove interlock, which, in addition to limiting the shrinkage, also enables the spring sleeve to be pretensioned will.

Ext iriding offers considerable advantages: The shrinkage takes place under a very even counterpressure, which is determined from the outset by a desired, adjustable pretension; the degree of shrinkage can be adjusted to a certain HbB. A very uniform crsm quality is achieved, which can represent the desired optimum in terms of color absorption capacity and elasticity, for example when you are working on twine made of synthetic fibers, such as nylon, fsestewsr or the like. thinks. The pre-tensioning force applied to the new tube ensures that there is sufficient resistance when the yarn is wound up, without any breakdowns occurring. The outer surface of the sleeve does not have any recesses or interruptions at which it could get caught or become wavy, as is the case with known spring sleeves. The construction of the new case is simple despite the excellent properties mentioned above. The fact that the new lap carrier holds the thread against a uniform tension during the tailing, which is already present when the coffin is wound up due to the pretension fixed by the contact of the projection on one of the daifsaigsnut, a particular advantage of the invention lies in the uniformity of the Treatment of the Saras.

Claims (2)

The excellent properties of the new sleeve justify the economic use of expensive high-quality stainless steel alloys, such as those on the market as non-rusting nickel steels and the like, or spring steels equipped with a stainless surface or other resilient, corrosion-resistant, permanent materials that ensure that the fibers do not during the fixing process yellow. An exemplary embodiment of the invention is shown in the drawing. The sleeve 1 is open; their jacket edges overlap at 2. The outer overlap piece has a pin 3 inside which protrudes into a circumferential groove 4 of the inner overlap piece. As a result of a given bias, the pin 3 is already tight on one end of the good in the drawn furthest open position. Against this bias resistance, the wound laser must shrink, the two overlapping ends being pushed further into one another until the pin 3 comes to rest on the other end of the lut 4 and thus any further shrinkage is eliminated. The degree of shrinkage is thus precisely determined by the length of the skin and can consequently be as desired. can be set. Grooves 5 lying transversely to the yoke direction at a distance of approx. 0.5 to 1.0 centimeters prevent the thread from being shifted or drawn in when it is wound up. 1. Elastic winding support in the form of a themselves with their Sheath overlapping sleeve for the treatment of yarns, characterized in that the two overlap The inner sides of the jacket interlock in the overlap area (2) by means of the projection (3) ″ and the circumferential groove (4), which, in addition to limiting the shrinkage, also enables the iWerhülae (1) to be pretensioned. 2. Elastic winding support, essentially as described and shown.
