Abstract:
1. A transfer device intended for transferring a reinforcing ply having the overall shape of a non-rectangular parallelogram and containing reinforcing threads with ferromagnetic properties making a given acute angle with the longitudinal direction of the said reinforcing ply, comprising at least two transfer belts which overlap over a given length 1 and are separated by a given and small-sized distance e, each of the belts comprising a magnetized region of trapezoidal shape, the bases of which are parallel to the longitudinal direction of the belts and are intended to hold the reinforcing ply firmly against the moving surface of the said transfer belts, wherein, in the region of overlap of the belts, the side of the trapezium connecting the two bases of the magnetized region of the second belt forms an angle a 2 with the longitudinal direction which is smaller than or equal to 90°, and the side of the trapezium connecting the two bases of the magnetized region of the first belt forms an angle a 1 with the longitudinal direction which is smaller than the angle a 2 , and wherein the magnetized regions of the two belts do not overlap, so as to form a non-magnetized region positioned in line with the region of overlap of the transfer belts.
