Claim:
Method for the manufacture of a reinforced diamond-coated cable for cutting structures and materials of steel, concrete, steel and concrete, stone materials or the like, in which the said diamond-coated cable comprises a plurality of outer strands ( 101 ) preferably of metal material such as steel or the like wound in a helix around a possible inner central strand ( 201 ) and a series of sheaths ( 2 ) inserted along the said outer strands ( 101 ) bearing projecting members of strongly abrasive material such as industrial diamonds or the like on the outer profile ( 202 ), characterised by the following stages: a) at least partly unwinding the outer strands ( 101 ) between each pair of successive sheaths ( 2 ′ 2 ″) so as to space them apart to create a free space ( 3 , 3 ′) between the outer strands ( 101 ) and the central strand ( 201 ), b) inserting a rigid mechanical interference member ( 4 , 6 ) in the space between one outer strand and the other and in the said free space ( 3 , 3 ′) to create an enlarged zone of suitable diameter (D) between each pair ( 2 ′, 2 ″) of successive sheaths, c) again helically winding the outer strands ( 101 ) around such rigid mechanical interference member ( 4 , 6 ).
