Cladding device used for multilayer composite braided fiber ringlike bands

The invention discloses a cladding device used for multilayer composite braided fiber ringlike bands. The device comprises a rack, a cladding die, a tensioning and hauling bracket, torpedo-head spreaders and a pair of hauling and conveying rollers, wherein the cladding die is fixed to the rack, the tensioning and hauling bracket faces directly the cladding die and is slidably arranged on the rack; the torpedo-head spreaders are arranged on the tensioning and hauling bracket and separate the multilayer composite braided fiber ringlike bands; hauling and conveying rollers are connected to the tensioning and hauling bracket through shafts and drive the separated multilayer composite braided fiber ringlike bands to penetrate through the cladding die. By means of the device, the multilayer composite braided fiber ringlike bands are evenly coated with polyurethane internally and externally through the die, and a high pressure resistant polyurethane water band pipe which is smooth and flat in internal surface and external surface is produced out.
