ABSTRACT:
The invention provides a method and apparatus for the manufacture of helically wound paperboard tubes having a highly uniform outside diameter. The method of the invention involves the application of controlled compressive force to at least one of the paperboard plies fed to a helical winding operation in order to control the thickness of the ply or plies and thereby control the outside diameter of the helically wound tube. In one preferred apparatus embodiment of the invention, the compressive force applied to the paperboard ply is applied via a pair of cooperating compression rolls. The nip between the two cooperating rolls is controllably varied by mounting one of the rolls for rotation about a shaft which is rotatable about an eccentric axis which is parallel to and offset from the axis of rotation of the roll. The rotation of the shaft thus causes the roll to move toward or away from the other cooperating roll and thereby varies the nip spacing between the rolls.
