1459653 Supporting and conveying a spirally wound tube KURARAY CO Ltd 6 Nov 1974 [7 Nov 1973] 48027/74 Heading F2P Apparatus for supporting and conveying a tube 8 formed from a helically wound strip and having a helical seam, comprises two or more parallel spaced apart shafts, 11, each supporting a plurality of support rollers 12, each support roller having its axis adjustably inclined relative to the longitudinal axis of the shaft 11, on which it is supported. The support rollers 12 are positioned by stop means 13 on the shafts 11 and may be tilted by tilt rollers 14 which abut one side of their respective support rollers. The bore of each support roller 12 has a curved surface (121) (Fig. 5, not shown) the curvature of which depends on the thickness of the roller. Each support roller is adjusted to a tilt position such that its angle of tilt relative to the tube 8 is the same as that of the helical seam of the tube. Tilt rollers 14 are mounted on members fixed to a slide bar 19 movable along a slide 9 and their position relative to the slide 9 is fixed by a bolt 20 which locks the bar 19 relative to the slide 9. Movement of the slide bar 19 along the slide 9 prior to locking by said bolt, moves the tilt rollers simultaneously and each support roller is tilted to the same angle. In a further embodiment (Fig, 8, not shown) resilient members (24) such as springs are incorporated on shafts 11 to help maintain the support rollers 12 in their tilted positions. The tilt rollers 14 may be fitted to a shaft (21) and a threaded portion (23) connects said shaft to a handle (22). By rotating the handle (22) the shaft (21) is moved in a direction parallel to the longitudinal axes of the tube 8 and shafts 11 and dependent on the direction of rotation of said handle, and the angle of tilt of the support rollers 12 is adjusted accordingly. One or more of the shafts supporting the support rollers 12 may be driven and suitable drive arrangements comprising belts and pulleys are disclosed in the Specification.
