Spirally wound tube rolling mechanism - has corrugated strip guide roller set with variable angle plane to produce various diameter tubes

摘要

The mechanism uses corrugated strip for producing spirally wound tubes of various diameters. The mechanism consists of base plate (2) on which the rolling assembly (3) is mounted. The rolling mechanism consists of ring-shaped carrier plate (4) with supporting rollers (5) rotating on the circumference of the tube (1) to be rolled. On the inlet point of the strip (8) the rolling mechanism has two intake rollers (9,10) which are driven and act on the edges of the strip (8). The inner intake roller (9) is fitted on the outside of the rolling mechanism and roller (10) is positioned on the external area of the roller mechanism. The mechanism is fitted with drive rollers (18) acting on the edges of the strip. The angle alpha enclosed by the strip and the connecting line of two opposite roller centres is smaller than ninety degrees.
