Woven fabric belt device
View Patent ↗The woven fabric belt device includes a connecting device ( 7 a ′; 7 b ′) located at at least one end of the woven fabric belt ( 20′, 21 ′). The connecting device is connectable to another connecting device ( 7 b ′; 7 a ′) of the same belt or of another one through a detachable connecting means ( 9 ′). A number of certain longitudinal yarns ( 2′, 2 ″) are removed or extend from the fabric ( 20 ′) along a section ( 4′, 4 ″) assigned to the end of the woven fabric belt. According to the teachings of the invention, the removed or extending sections ( 4′, 4 ″) of the longitudinal yarns ( 2′, 2 ″) are arranged so as to rest on at least one side of the woven fabric belt ( 20′, 21 ′) in a region located in front of the connecting device ( 7 a ′; 7 b ′) so that a support ( 10′; 10 ″) for protecting the connecting devices ( 7 a ′; 7 b ′) Is provided when the woven fabric belt travels over a working area (AF).
