Strip with fabric having exactly two layers of fabric

Abstract

A belt, in particular a drive belt, is proposed having a woven fabric (G) as a traction layer, said fabric comprising two woven fabric layers, which are interlaced together. Both woven fabric layers have plain weaves. Such a belt transmits high tractive forces, while remaining flexible at the same time.

1 . Drive belt having as a traction layer a woven fabric (G), which comprises exactly two layers of woven fabric ( 1 , 2 ), which are interlaced together, characterized in that at least one of the woven fabric layers ( 1 , 2 ) has a plain weave, a derived plain weave, a mixed plain weave or a satin weave.  
     
     
         2 . Drive belt according to  claim 1 , wherein the other woven fabric layer ( 2 , 1 ) has the same type of weave.  
     
     
         3 . Drive belt according to  claim 1 , wherein the other woven fabric layer ( 2 , 1 ) has another type of weave.  
     
     
         4 . Drive belt according to any one of  claims 1  to  3 , wherein the smallest weave unit (P 1 ) of the woven fabric is constructed according to the pattern shown in FIG. 11 of the drawings,  
       where the columns each represent the warp threads (K 1 , K 2 , K 3 , K 4 ) and the rows each represent the weft threads (S 1 , S 2 , S 3 , S 4 ), and where in the columns alternately a warp thread (K 1 , K 3 ) of one layer ( 1 ) is arranged next to a warp thread (K 2 , K 4 ) of the other layer ( 2 ) and where in each of the rows a weft thread (S 1 , S 3 ) of one layer ( 1 ) is arranged next to a weft thread (S 2 , S 4 ) of the other layer ( 2 ), and where a dark field in this pattern denotes that the warp thread passes over the weft thread and where a light coloured field in this pattern denotes that the warp thread passes under the weft thread.  
     
     
         5 . Drive belt according to any one of  claims 1  to  3 , wherein the smallest weave unit (P 2 ) of the woven fabric is constructed according to the pattern shown in FIG. 9 of the drawings,  
       wherein the columns each represent the warp threads (K 1 , K 2 , K 3 , K 4 ) and the rows each represent the weft threads (S 1 , S 2 , S 3 , S 4 ) and where in the columns alternately a warp thread (K 1 , K 3 ) of one layer ( 1 ) is arranged next to a warp thread (K 2 , K 4 ) of other layer ( 2 ) and where in each of the rows a weft thread (S 1 , S 3 ) of one layer ( 1 ) is arranged next to a weft thread (S 2 , S 4 ) of the other layer ( 2 ), and where a dark field in this pattern denotes that the warp thread passes over the weft thread and where a light coloured field in this pattern denotes that the warp thread passes under the weft thread.  
     
     
         6 . Drive belt according to any one of  claims 1  to  3 , wherein the smallest weave unit (P 3 ) of the woven fabric is constructed according to the pattern shown in FIG. 10 of the drawings,  
       wherein the columns each represent the warp threads (K 1 , K 2 , K 3 , K 4 ) and the rows each represent the weft threads (S 1 , S 2 , S 3 , S 4 ) and where in the columns alternately a warp thread (K 1 , K 3 ) of one layer ( 1 ) is arranged next to a warp thread (K 2 , K 4 ) of the other layer ( 2 ) and where in each of the rows a weft thread (S 1 , S 3 ) of one layer ( 1 ) is arranged next to a weft thread (S 2 , S 4 ) of the other layer ( 2 ), and where a dark field in this pattern denotes that the warp thread passes over the weft thread and where a light coloured field in this pattern denotes that the warp thread passes under the weft thread.  
     
     
         7 . Drive belt according to any one of  claims 1  to  6 , wherein the woven fabric (G) contains electrically conducting fibers.
