摘要： A chuck assembly for insertion into the core of a paper windup roll to assure uniform winding and unwinding. The chuck assembly includes a shaft which has an axis coinciding with the desired axis of rotation of the core and bearing means which support the shaft for rotation therein. At the end of the shaft there is a stub shaft of reduced diameter which is received within a chuck having an axial bore therein. The bore is sufficiently larger in diameter than the diameter of the stub shaft to permit limited relative movement. The chuck further has a tapered wedge at its forward end which is arranged to fit tightly within the core and resilient spring means are provided to accommodate the relative movement between the stub shaft and the larger diameter bore in which it is located.

摘要： Noise-causing vibrations in the span of a tensioned web running over and away from an arcuate guide surface area of a circular perimeter fixed guide bar at a speed such that in the off-running angle between the web and the curved perimeter of the bar, air moving in the direction of the web in such angle would tend to follow the curvature of the bar (Coanda effect) and cause splitting of the air between the web and the bar, inhibited by locating spoiler means in a plane extending substantially tangentially from the off-running side of the arcuate guide surface area. The spoiler means is desirably in the form of one or more ribs providing surface in the tangential plane. Where the web span runs between spaced fixed circular perimeter bars, spoiler means may also be located in a plane extending substantially tangentially toward the on-running side of the arcuate guide surface of the bar located at the downstream end of the span.

摘要： A method and mechanism for winding a roll from a continuous traveling web including first and second parallel winder drums supporting the wound roll and one or more rider rolls on top of the roll being wound with the rider roll circumferential location being changed during the winding of the roll to compensate for the changing spring constant of the roll being wound, and in one form applying a force with a second rider roll and in another form with a third rider roll with the rolls being changed in position relative to the roll being wound independent of each other.
