DEVICE FOR IMPREGNATION OF COMPOSITE MATERIAL REINFORCEMENT WITH BINDER Russian patent published in 2009 - IPC B29B15/10 

FIELD: technological processes.

SUBSTANCE: invention concerns impregnation of cellular and porous materials, particularly of fabric, bands, strings. Device for impregnation of composite material reinforcement by a binder includes sealed case with tank for excessive binder collection under it. Work gas feeding collector, binder feeding collector, valve of work gas discharge from sealed case, reinforcement feeding roll, and impregnated reinforcement receiving roll are mounted on the case. Reinforcement receiving roll with anti-adhesive coating applied to its external cylindrical surface is mounted at the point of reinforcement input into the sealed case above the tank for excessive binder collection. To apply binder onto reinforcement, one or more binder pulverisers are set around the roll with anti-adhesion coating, gas-feeding nozzle axes of pulverisers cross rotation axis of the roll. Binder pulverisers are connected to work gas feeding collector by work gas feeding hoses and to binder feeding collector by binder feeding hoses. Rolls for regular distribution of binder over reinforcement are set below the roll with anti-adhesive coating, further rolls and sponges for excessive binder expression are mounted, and calibration rolls are mounted at the output of the sealed case.

EFFECT: regular distribution of binder in composite material reinforcement.
