A device for manufacturing a reinforcing ply N by assembling lengths of strip cut at an angle, comprising: a feed means (300) for delivering a strip (B), an assembly belt (101), a transfer means (200) for conveying onto the assembly belt a given length of straight-grain strip in a direction (AA′) comprising a retaining wall (211), parallel to the planes of the assembly belt (101) and of the feed means, and a first face (211a) of which is intended to come into contact with the surface of the strip, in which device the feed means (300), the transfer means (200) and the assembly belt (101) are fitted with magnetic means. The retaining wall (211) is able to move up and down and back and forth, and the magnetic means are adjusted so that when the device is in operation: in the lowered position, the said magnetic means of the transfer means (212) exert on the metallic threads of the strip a magnetic field of a strength higher than the strength of the magnetic field exerted by the magnetic means (102, 103, 104) positioned on the feed means (300), in the raised position, the said magnetic means of the transfer means (212) exert a magnetic field of a strength weaker than the strength of the magnetic field exerted by the magnetic means positioned on the assembly belt (101). |
