Riemohen for drafting equipment from spinner eimaeohiinen

The innovation concerns an apron for drafting systems of spinning and twisting machines.

Technical leather is generally used for the aprons of the drafting systems of spinning and twisting machines »where the aprons preferably run with their meat side on profiled surfaces of upper and lower rollers. The aprons are subject to a relatively large amount of wear and tear occurring lliprieb, so that a relatively frequent renewal this strap is necessary if a proper spinning process is to be guaranteed.

All belts for drafting _{devices of spinning machines (} also known as plastic belts, which are made in the form of a tube and cut from this tube) have become known. However, it has been shown that plastic belts cannot be used in all cases as a substitute for leather belts, quite apart from the fact that the production of the plastic straps is very expensive because of the accuracy required.

Ss has therefore already been proposed, for example the flesh side of a cylinder leather with a rubber elastic \ To coat material that penetrates the surface of the leather and can thus achieve a firm hold on the leather. These straps have the advantage that they have a longer stability own, but still the ones for drafting systems from spinning machines retain special advantageous properties of the leather. Since such aprons for drafting systems from However, spinning machines are very expensive to manufacture, the present innovation is based on the task of remedying this create and develop a strap that generally has the properties of the coated leather straps, but nevertheless can be manufactured very easily and cheaply.

Based on the knowledge that sea is necessary for this purpose ) will be to use a material that has roughly the same physical properties as leather, the innovation is marked by a P ^ netstoffsträgerschicht, which is preferably in the type of a gap yderimitation formed and on both sides with a thin layer of rubber elastic material is provided. The plastic carrier layer can expediently consist of a thin one Plastic fiber fleece exist, which or the like by binders. is held together. It has proven to be particularly advantageous if a binder - applied to the nonwoven fabric -

Worn Lateocachioht intended _for the vulcanized 1st «Bel

this carrier layer can be made of rubber "" elaetlsohem material directly and without the addition of a Adhesive are applied »whereby they are in the surface of the Plastic carrier penetrate well and create an intimate connection with the frägersohioht can achieve. The new strap points on these catfish a good shelf life and large Abrlebfestlgkelt on.

Sine example of execution of a strap ^ for Streokwerke from A model of the spinning mill according to the wage is attached *

From this model it can be seen that an atdiäohat with latex sprayed fiber fleece, which is then calendered and in the process has been vulcanized, in a later operation with a thin layer of rubber-coated material on both sides was provided. This layer can be made of latex, for example consist of Butadlen-Aorylnitrll-Mlsohpolymerlsaten. Bs kttnnt « but also a layer of polyurethane or ethylene vinyl acetate to be applied «The applied latex coating is not needed more detachable from the carrier layer.

The strap itself is made by cutting out a strip and gluing it together. Sa offers the advantage, as can be seen from the model, that there is no joint at the glue point. With the bonding of the carrier layer, a very intimate connection can still be achieved. As gummielaetiaelie layer comprises a synthetic rubber is used as _t in this abrasion skill iat greater for straps of Streokwerken best.
