Patent number: 9714483Abstract: An endless fabric belt for use in a paper, cardboard or tissue machine has machine-direction threads and cross-machine-direction threads. At least part of the threads are yarns composed substantially of a thermoplastic polymer material which is transparent for light of a wavelength. The fabric belt is a flat-weave with two front-side ends that are subsequently connected by bringing together end sections of the machine-direction threads in pairs with the formation of junction points and are woven with cross-machine-direction threads, forming a seam region. A material-to-material bond is formed in the seam region by absorbing light at the wavelength at yarn contact points. In the seam region, a plurality of spaced-apart, strip-shaped fabric sections are formed, in which the junction points and the yarn contact points which are connected to one another are arranged, and one strip-shaped fabric section without junction points is formed between two immediately adjacent fabric sections having the junction points.Type: GrantFiled: April 18, 2013Date of Patent: July 25, 2017Assignee: Voith Patent GmbHInventors: Michael Straub, Robert Eberhardt
