FIELD: processing of plastics and composition materials, namely processes and equipment for making plastic tubes with colored stripes. SUBSTANCE: method comprises steps of preparing melt and pressing out tubular blank; supplying preliminarily prepared colored strip film to outer surface of tubular blank and realizing its contact with tubular blank at calibrating in such way that to depress colored film into outer surface of tubular blank; using vacuum calibrating device made of two portions for calibrating blank; keeping evacuation degree in first portion of calibrating device lower than in second portion at least by 1.25 times; cooling tubular blank for forming monolithic structure of tube with colored film depressed into its surface. Apparatus for performing the method includes extruder with head, vacuum calibrating device, reels with colored film wound onto them, guides for strip films and unit for cooling tube. Reels with wound film are arranged on calibrating device. Guides for colored film are mounted on end surface of calibrating device turned to head of extruder. EFFECT: uniform feed of colored films, formation of monolithic structure of tube and film, elimination of exfoliation of film from outer surface of tube. 14 cl, 7 dwg
