Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Es ist bereits bekannt, Manchons bzw. Trockenfilze für die Papierfabrikation o. dgl. dadurch herzustellen, daß Fließbänder in mehreren, sich kreuzenden Lagen zu einer Walzenform gewickelt und sodann verfilzt werden. Durch dieses Verfahren werden jedoch ungleichmäßig starke und dichte Manchons o. dgl. hergestellt, deren Fehler nur mühsam und meistens nur unvollständig ausgebessert werden können. Dieser Nachteil wird gemäß der Erfindung dadurch beseitigt, daß zur Herstellung des Manchons o. dgl. Garne aus verfilzbarem Fasergut verwendet werden. Diese werden ebenfalls walzenförmig in mehreren, sich kreuzenden Lagen gewickelt und sodann untereinander verfilzt.It is already known that manchons or drying felts for paper manufacture o. by producing conveyor belts in several intersecting layers to form a roller shape wrapped and then matted. However, this process will become uneven Strong and dense Manchons o. The like. Manufactured, their faults only with difficulty and mostly can only be repaired incompletely. This disadvantage becomes according to the invention thereby eliminating the fact that for the production of manchon o. The like. Yarns from feltable Fiber material can be used. These also become cylindrical in several intersecting ones Wrapped layers and then felted together.

Bei Ausführung dieses neuen Verfahrens werden zweckmäßig zuerst stärker gedrehte Fäden aus verfilzbarem Fasergut über eine oder mehrere Walzen schraubenförmig gewickelt und zwar dicht oder locker nebeneinander in zwei oder mehreren, sich gegenseitig kreuzenden Lagen. Sodann werden weniger und zuletzt, zur Bildung der äußeren Schicht des Manchons o. dgl., ganz wenig gedrehte oder gegebenenfalls bloß genitschelte Garne verwendet, die dicht nebeneinandergelegt werden, wonach das Ganze in üblicher Weise verfilzt wird. Dadurch wird ein Manchon o. dgl. von vollkommen gleichmäßiger Oberfläche hergestellt, dessen innerer Teil aus zugfesteri Fäden besteht, so daß der Manchon auch einer starken Spannung nicht nachgibt. Bei der Wicklung werden vorteilhafterweise gleichzeitig mehrere nebeneinander geführte" Fäden aufgewickelt. When executing this new method, it is advisable to first turn more heavily Threads made of feltable fiber material wound helically over one or more rollers and that close or loosely next to each other in two or more mutually crossing Locations. Then less and finally, for the formation of the outer layer of the manchon or the like, very little twisted or if necessary, only nitled yarns are used, which are laid close together, after which the whole thing is matted in the usual way. This makes a manchon or the like of Made of a perfectly even surface, the inner part of which is made of high tensile strength threads exists, so that the Manchon does not give in to even a strong tension. When winding a plurality of "threads" guided next to one another are advantageously wound up at the same time.

Selbstverständlich können zur Herstellung des ganzen Manchons o. dgl. auch gleich stark, und zwar mittelmäßig oder ganz schwach gedrehte Garne verwendet werden, wobei das so hergestellte Erzeugnis ebenfalls eine gleichmäßige Stärke und Dichte und eine ziemlich hohe Zugfestigkeit aufweist.Of course, for the production of the whole manchon or the like, you can also use the same strength, medium or very weakly twisted yarns are used, whereby the product thus made also has a uniform thickness and density and a fairly has high tensile strength.
