Estimating the term…
Abrasive belt with an abrasive-grain layer on a base containing a textile terial, 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.
An abrasive belt with an abrasive-grain layer on a base containing a textile material, and with a joint which extends transversely to the longitudinal direction of the belt and which 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 extending transversely to the joint, characterized in that the set of parallel threads (2) forms a non-interwoven layer which is located on the side of the textile material facing the abrasive-grain layer (1) and which is held together by a further layer (3) which is arranged on the side of the textile material facing away from the abrasive-grain layer and in which the rebate for the joining strip is located so that the layer of parallel threads remains intact.
