Abstract

The rubberised woven strips are composed of strong wefts and weaker warps, forming woven strips at least 10 m long.

Description

Gegenstand der vorliegenden Erfindung ist die Verwendung von gummierten Gewebestreifen bestehend aus einem starken Querfaden und einem schwachen Längsfaden als Einlage von Handläufen.The present invention relates to the use of rubberized fabric strips consisting of a strong cross thread and a weak one Longitudinal thread as a handrail insert.

Derartige gummierte Gewebestreifen bewirken als Einlage von Handläufen die geforderte Quersteifigkeit, ohne die gleichzeitig geforderte Elastizität zu beeinträchtigen.Such rubberized fabric strips act as an insert of Handrails meet the required lateral stiffness without the one impair the required elasticity.

Derartige gummierte Gewebestreifen werden bisher hergestellt, indem Gewebebahnen mit einem starken Faden als Kette und einem schwachen Faden als Schuß ein- oder zweiseitig gummiert und quer zur Gewebebahn in Streifen der gewünschten Breite geschnitten werden, woraufhin sie in an sich bekannter Weise in den Handlauf mit eingebaut und letztlich einvulkanisiert werden (siehe US 5 255 772 A).Such rubberized fabric strips have so far been produced by weaving webs with a strong thread as a chain and a weak thread as a weft gummed on one or two sides and across cut into strips of the desired width for the fabric web be, whereupon they in a known manner in the handrail with built in and ultimately vulcanized (see US 5 255 772 A).

Derartige gummierte Gewebestreifen stehen somit nur als relativ kurze Stücke zur Verfügung, deren maximale Länge bestimmt wird durch die Breite der ursprünglich eingesetzten Gewebebahnen.Such rubberized fabric strips are therefore only relative short pieces are available, the maximum length of which is determined by the width of the fabric webs originally used.

Es ist somit bisher notwendig, bei der Herstellung von Handläufen diese gummierten Gewebestreifen anzustückeln, wobei eine Überlappung genauso vermieden werden soll wie eine Lücke zwischen den beiden Schnittkanten des Streifens. Dies ist ein Aufwand, der nur durch sehr präzise und manuelle Anstückelung bewältigt werden kann. Dieser Aufwand ist ein wesentlicher Kostenfaktor und führt darüber hinaus bei nicht präziser Durchführung zu Schwachstellen im fertigen Handlauf. So far it has been necessary in the manufacture of handrails to patch these rubberized fabric strips, one Overlap should be avoided just like a gap between the two cut edges of the strip. This is a Effort that only through very precise and manual incrementation can be dealt with. This effort is essential Cost factor and also leads if the implementation is not precise weak points in the finished handrail.

Es besteht somit das Bedürfnis nach gummierten Gewebestreifen bestehend aus einem starken Querfaden und einem schwachen Längsfaden, die in Längen von mindestens 10 Metern vorliegen, und vorzugsweise sogar die Länge des gesamten Handlaufs aufweisen.There is therefore a need for rubberized strips of fabric consisting of a strong cross thread and a weak one Longitudinal threads that are at least 10 meters long and preferably even have the length of the entire handrail.

Es ist jetzt gelungen, derartig lange gummierte Gewebestreifen herzustellen, indem als Gewebebahn ein Material verwendet wird, dessen schwache Fäden die Kette und starke Fäden den Schuß bilden. Derartige Gewebebahnen können nach der Gummierung in Längsrichtung zu sehr langen gummierten Gewebestreifen geschnitten werden. Die Herstellung von derartigen Gewebebahnen ist zwar schwieriger und aufwendiger als die bisher übliche Herstellung von Gewebebahnen mit starken Fäden als Kette und schwachen Fäden als Schuß. Der Aufwand der Herstellung von Gewebebahnen der umgekehrten Struktur ist aber gerechtfertigt durch den Gewinn an Qualität und die Einsparung an Herstellkosten beim Einbau von daraus hergestellten gummierten Gewebestreifen in Handläufen. Außerdem sind diese gummierten Gewebestreifen gut einsetzbar bei der Herstellung von Förderbändern und Autoreifen.It has now succeeded in making such long rubberized strips of fabric by using a material as the web of fabric, its weak threads the warp and strong threads the weft form. Such webs of rubber can in Cut lengthwise to very long rubberized fabric strips become. The production of such fabric webs is true more difficult and expensive than the usual production of fabric webs with strong threads as a chain and weak threads as a shot. The effort of making fabric sheets reverse structure is justified by the profit in quality and the saving in manufacturing costs during installation of rubberized fabric strips made from it in handrails. In addition, these rubberized fabric strips can be used well in the production of conveyor belts and car tires.

Bei der Verwendung von derartig gummierten Gewebestreifen ist es somit möglich, Handläufe herzustellen, deren Einlage nur noch ein einziges Mal oder sehr selten unterbrochen ist, nämlich dort, wo die beiden Enden des Handlaufes miteinander verbunden sind oder längere Stücke von mindestens 5 bis 10 Metern mit verwendet werden.When using such rubberized strips of fabric it is therefore possible to produce handrails, the inlay of which is only is interrupted once or very rarely, namely where the two ends of the handrail are connected are or longer pieces of at least 5 to 10 meters with be used.

Claims (2)

  1. Use of rubber-coated woven fabric strips as inlays of handrails, characterized in that rubber-coated woven fabric strips with a length of at least 10 meters having been cut lengthwise after the rubber coating are used which consist of a strong crosswise thread which causes crosswise stiffness and a weak lengthwise thread, wherein said strong thread is the weft and said weak thread is the warp.
  2. The use according to claim 1, characterized in that said woven fabric strip has the same length as the handrail.
