  • Clothing and method for producing a clothing
    Patent number: 11332854
    Abstract: A clothing, in particular a drying wire, for a machine for producing a fibrous web, such as a paper or cardboard web, is a planar textile structure from yarns which intersect in a machine direction and in a cross-machine direction. The planar structure has two edges oriented in the machine direction and two edges oriented in the cross-machine direction. The clothing is joinable along the edges oriented in the cross-machine direction in the machine so as to form an endless belt. The clothing is only calendered by introducing energy in peripheral regions which extend along the edges oriented in the machine direction and/or along the edges oriented in the machine cross direction, on account of which in the peripheral regions the MD yarns are welded to the CMD yarns, and the thickness and/or permeability of the clothing are/is reduced.
