Description
Weichwalze für Glätt- und Prägezwecke für Textil- und Papierkalander bestehen aus einem Metallkern mit seitlichen Verschlusscheiben, zwischen welchen sich die elastische Masse befindet. Diese besteht vielfach aus Textilfasern, die in Form von Gewebe oder Geflechten auf den Metallkern aufgebracht und unter hohen Druck an einer homogenen Masse verpresst werden. Die Herstellung solcher Walzen wird durch die erforderlichen maschinellen Vorarbeiten, z.B. das Weben und Flechten, sehr verteuert.Soft rolls for smoothing and embossing purposes for textile and paper calenders consist of a metal core with lateral locking disks, between which the elastic mass is located. This often consists of textile fibers that are applied to the metal core in the form of fabrics or braids and pressed together to form a homogeneous mass under high pressure. The production of such rolls is very expensive due to the necessary preliminary mechanical work, e.g. weaving and braiding.
Es wurde nun gefunden, dass an Stelle der bisher üblichen Gewebe oder Geflechte auch ungeformtes Fasermaterial zur Herstellung von Weichwalzen benutzt werden kann, z.B. Kämmlinge, Textilfäden u.dgl., die allein oder vermischt zur Anwendung kommen können. Dieses Material wird innerhalb einer dem Walzendurchmesser entsprechenden Form um einen Kern gelegt, und zwar so, dass die Fasern oder Fäden sich gewebe- oder geflechtartig kreuzen. Durch das spätere Pressen entsteht eine innige Verbindung des Textilmaterials, welche die eines künstlichen Gewebes oder Geflechtes noch übertrifft. Ein geeignetes Verfahren zur Herstellung solcher Walzenbeläge besteht darin, dass das lose Textilmaterial zunächst in genügender Dicke flach ausgebreitet und dann zusammengerollt wird, worauf diese Rollen um einen Kern gelegt oder gewickelt werden. Auf diese einfache Weise erzielt man eine gewebe- oder geflechtartige Kreuzung und innige Verbindung des Fasermaterials.It has now been found that, instead of the previously usual fabrics or braids, unformed fiber material can also be used for the production of soft rolls, e.g. noils, textile threads and the like, which can be used alone or mixed. This material is placed around a core within a shape corresponding to the roller diameter, in such a way that the fibers or threads cross each other in a woven or braid-like manner. The subsequent pressing creates an intimate connection of the textile material, which even surpasses that of an artificial fabric or braid. A suitable method for producing such roller coverings is that the loose textile material is first spread flat to a sufficient thickness and then rolled up, whereupon these rolls are turned a core can be laid or wound. In this simple way, a fabric-like or braid-like crossing and an intimate connection of the fiber material is achieved.
