Abstract

A spiral wire, comprising adjacent thread spirals (1) positioned in pairs with loops thereof interlapping to form transverse rows of loops in the wire, and linking threads (2) inserted in the rows of loops. The opposite ends of the spiral wire are interconnected by means of a seam thread (2A) into an endless wire. In order to make it easier to insert the seam thread, a clearance (X) is provided between the interlapping loops (1Aa) of the two spirals (1A) forming the seam position, which clearance extends in the direction of the seam thread so that the loops are able to yield with respect to each other in that direction. The spirals of the seam portion are preferably made of a thinner thread, a thread having a flat cross-section or interconnected with a sparser spacing of the loops.
