PERFORATED HOSES, AND APPARATUS AND METHOD FOR PRODUCING SAID PERFORATED HOSES

摘要

An apparatus and method for manufacturing a perforated hose is provided for producing hoses made of PE fabric or LLDP vinyl materials. The hose provides multiple perforations on the surface arranged in certain patterns. The apparatus for manufacturing a perforated hose comprises: a raw fabric roll (110, 210), a printing unit (140, 240), a perforating unit (150, 250), a hose forming unit (160, 260), a final product reel (119, 219) and set of auxiliary rollers (171~178, 271~278). A perforation is performed by utilizing a laser beam emitted from a laser beam generating unit (152, 252), inducing the laser beam lengthwise and widthwise along the surface of the hose to concentrate on the surface of the raw PE knitted fabric and LLDP vinyl materials, and forming various patterns of perforations on the surface of the hose.
