Patent ID: 7267219

Claim:
Conveyor belt comprising a layered composite of: i) a textile ply ( 1 ) with a first ply surface ( 11 ) and a second ply surface ( 12 ); ii) a first plastic layer ( 2 ), which adheres to the first ply surface ( 11 ), of a thermoplastic plastic with a creeping strength v k of at the most 0.005 at 30° C., which contains at least 70 percent by weight of a non-crosslinked thermoplastic with a creeping strength v k of at the most 0.005 at 30° C.; and iii) a second plastic layer ( 3 ), which adheres to the second ply surface ( 12 ), of a thermoplastic plastic with a creeping strength v k of at the most 0.005 at 30° C., which contains at least 70 percent by weight of a non-crosslinked thermoplastic with a creeping strength v k of at the most 0.005 at 30° C.; with the proviso that the quotient r v gives a value in the range of 5 to 25 according to the following Formula (I): r V = V B ⁢ ρ T G T - 1 , ( I ) wherein V B denotes the volume per unit area of the said layered composite and ρ T denotes the density of the textile ply ( 1 ), and G T denotes the weight per unit area of the textile ply ( 1 ).
