Abstract

Abstract Abrasive belt with an abrasive-grain layer on a base containing a textile material, and with a joint extending transversely to its longitudinal direction. The latter contains a joining strip in a rebate on the side of the base facing away from the abrasive-grain layer. A set of parallel threads of the textile material extends transversely to the joint. To increase the quality of the joint, the textile material used is one in which the set of parallel threads forms a non-interwoven layer. This thread layer is arranged on the side of the textile material facing the abrasive-grain layer. This layer is held together by a further layer arranged on its side facing away from the abrasive-grain layer. Since the rebate is located in this further layer, the threads responsible for transmitting the longitudinal tensile forces and extending transversely to the joint remain unaffected.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 139 words
An abrasive belt with a layer of abrasive grains (1) on a support comprising a textile material and with a joining seam (4) extending transversely to the longitudinal direction thereof and which comprises a coupling band (5) in a recess on that side of the support remote from the layer of abrasive grains, wherein a bundle of mutually parallel threads (2) of the textile material extends transversely to the joining seam (4), characterised in that the bundle of mutually parallel threads (2) forms a non-woven layer which is disposed on that side of the textile matrial nearest to the layer of abrasive grains (1) and which is held together by a further layer (3) provided on the side thereof remote from the layer of abrasive grains and in which further layer the recess for the band coupling is situated.
Claim 2
Dependent Claim 139 words
An abrasive belt with a layer of abrasive grains (1) on a support comprising a textile material and with a joining seam (4) extending transversely to the longitudinal direction thereof and which comprises a coupling band (5) in a recess on that side of the support remote from the layer of abrasive grains, wherein a bundle of mutually parallel threads (2) of the textile material extends transversely to the joining seam (4), characterised in that the bundle of mutually parallel threads (2) forms a non-woven layer which is disposed on that side of the textile matrial nearest to the layer of abrasive grains (1) and which is held together by a further layer (3) provided on the side thereof remote from the layer of abrasive grains and in which further layer the recess for the band coupling is situated.
Claim 3
Dependent Claim 19 words
An abrasive belt according to Claim 1, characterised in that the textile material is formed by a stitched fabric.
Claim 4
Dependent Claim 37 words
An abrasive belt according to Claim 1 or 2, characterised in that the bundle of mutually parallel threads (2) is formed by the warp threads extending longitudinally through the textile material, and a joining seam is provided.
Claim 5
Dependent Claim 52 words
An abrasive belt according to Claim 1 or 2, characterised in that it is in the form of a wide abrasive belt with a plurality of joining seams and the bundle of mutually parallel threads (2) extending transversely to the joining seam is formed by the weft threads of the textile material.
