Abstract
An industrial textile belt, a method for making it, and its use. The belt includes a seam with joining ends that can be joined together so that the belt becomes an endless loop. The joining ends have seam areas with cross-machine direction wear yarns on their machine surface. The wear yarns receive wear stress when the belt slides against the support surface of a processing device.
Claims10
An industrial textile belt for the processing of pulp or mass, the belt having a machine-direction width and a cross-machine direction length as well as a machine surface on the processing device side and a product surface on the processed mass side;
- and the belt comprises:
- several machine-direction yarns;
- a first joining end and a second joining end, the joining ends comprising seam areas with a machine-direction length;
- connecting elements at the outermost ends of the seam areas, whereby the joining ends of the belt are joinable to each other to form an endless structure;
- and wherein the machine surface of the seam area has at least one cross-machine direction wear yarn that covers the entire width of the belt in cross-machine direction and that is arranged into the basic structure of the belt but is functionally an extra wear-receiving yarn in respect of the basic structure of the belt;
- and the machine surface of the seam area has wear mass that covers at least part of the yarns of the seam area.
A method of manufacturing an industrial textile belt, the method comprising:
- forming a belt having a machine-direction length and a cross-machine direction width as well as a machine surface on the processing device side and a product surface on the processed mass side;
- weaving the basic structure of the belt from several machine-direction yarns and several cross-machine direction yarns;
- forming on the belt a first joining end and a second joining end as well as seam areas on both joining ends;
- arranging at the joining ends connecting elements for joining the belt into an endless loop;
- arranging on the machine surface of the seam area at least one cross-machine direction wear yarn to extend over the entire cross-machine direction width of the belt, the wear yarn being arranged into the basic structure of the belt but being functionally an extra wear-receiving yarn in respect of the basic structure of the belt;
- and applying wear mass to the seam area for covering at least part of the yarns of the seam area.
