Concentrated Reinforcing Bars And Method For Making Same
A process for manufacturing rods of reinforcement concentrates, a device for implementing the process, and products obtained. The method includes heating and shaping at least one bundle of strands having more than 70% by weight of reinforcing material and a moisture content of at least 0.1% before being cut up into rods.
1 - 7 . (canceled)
8 . A process for manufacturing rods of reinforcement concentrates, comprising:
heating and shaping at least one bundle of strands having more than 70% by weight of reinforcing material and a moisture content of at least 0.1% before being cut up into rods.
9 . The process as claimed in claim 8 , wherein at least some of the strands are composite strands formed from reinforcement filaments, or glass filaments, and filaments of at least one thermoplastic organic material.
10 . The process as claimed in claim 8 , wherein:
the bundle of strands furthermore undergoes a sheathing by passing through a die fed with at least one organic material, or with at least one organic material and at least one additive.
11 . A device for implementing the process as claimed in claim 10 , comprising:
one or more means for providing at least one bundle of strands;
at least one means for heating the bundle;
at least one shaping device;
at least one sheathing die; and
at least one cutting device.
12 . A reinforcement concentrated rod having a reinforcement content of greater than 65% by weight, reinforcements being bonded together or embedded in at least a first organic material sheathed with at least a second material.
