METHOD FOR MANUFACTURING A WEB OF LOOP MATERIAL AND BAND OF LOOP MATERIAL OBTAINED BY SAID METHOD

摘要

The present invention relates to a method of manufacturing a strip (1) of loop material, such as in particular a conveyor belt, a conveyor, a transmission belt or the like, in which the ends of said strip are assembled by interlocking two serrations (2a, 2b) of complementary shape, connected by at least one transverse locking rod (3) inserted through transverse orifices (2d) formed in the teeth of the serrations. This method is characterized in that it comprises a step in which to make the transverse orifices (2d), one slices longitudinally each end (la, lb) of said strip (1) to separate the upper face of the lower face of said strip (1) in a junction zone extending over a width at least equivalent to the area occupied by said transverse orifices (2d) to be made, at least one transverse pin (7) is provided in the junction zone of each ends (1a, 1b), reassembling the upper and lower faces of said strip in said junction area to reconstruct the ends (la, lb) of said strip (1), then removing said transverse pin (7) forming said transverse holes (2d).
