摘要:
The invention concerns a process for preparing a ribbon of reinforcement strands or filaments associated on each of its faces with a polymeric binder, said ribbon having a given width substantially constant over its entire length, in which the strands or filaments extend in a direction parallel to the length of the ribbon, wherein it comprises the following steps: a) adjustment of the ribbon width to the desired width thanks to a dimensioning device, b) association of the ribbon on each of its faces with a polymeric binder allowing the assurance of a homogenous cohesion of the ribbon, such that the total weight of the binder does not exceed 25% of the total weight of the obtained ribbon, as well as the ribbons obtainable by such a process.
