COMPOSITE REINFORCEMENT PRODUCTION LINE Russian patent published in 2006 - IPC E04C5/07 

FIELD: building, particularly production of pre-stressed reinforcing elements of material other than metal.

SUBSTANCE: production line comprises bobbin carrier with bobbins wound with roving, leveling device, annealing chamber, impregnating bath with tightening means, squeezing means, forming unit, transversal winding means, polymerization chambers, reinforcement reeling-on and cutting units and pulling means. The forming unit is made as matrix having longitudinal channels, arranged upstream of transversal winding zone and spaced a distance equal to (1-10)d from braid thread winding point, wherein d is reinforcement diameter. The squeezing means is made of elastic resilient material and is installed downstream of impregnating bath having tightening means. The tightening means is provided with tightening mechanism and is arranged in impregnating bath over polymeric binder surface. The leveling device is of comb-like type and has number of slots, which is not less than number of matrix channels. Matrix includes 2-10 channels uniformly distributed around central guiding means. Matrix guiding means is made as a cone or truncated cone and provided with additional channel. The squeezing means is made as a plate of elastic resilient material having cuts, wherein number of cuts is equal to number of matrix channels. The leveling device is formed of metal wire. Tightening means control mechanism is installed over impregnating bath. Production line also has winding braid removal unit, which takes winding braid from load-bearing rod. The removal unit is arranged downstream of polymerization chamber. Extrusion nozzles with heating members are eliminated from the production line.

EFFECT: simplified structure, increased output, provision of non-metal reinforcement with distinct periodical profile, increased mechanical-and-physical and reinforcing properties, accelerated forming operation due to prevention of friction between roving and extraction nozzle surfaces.
