Abstract: The present invention provides an overlay for overlying an edge, corner, or other non-planar extent of an object. The overlay includes first and second longitudinal portions interconnected to one another to form an included angle of generally 90.degree.. The first longitudinal portion has a plurality of segments, each having opposite end walls which form channels between adjacent segments. Each channel extends from a front channel opening to a longitudinally offset rear channel opening. Due to the channels between the segments, the segments are free to move relative to one another as the overlay is manipulated to conform to the non-planar extent of the object to be protected. At least some partial overlap always obtains between adjacent pairs of the segments so that the overlay provides protection irrespective whether it is overlying a non-planar extent which is generally concave or generally convex in shape.

Abstract: Apparatus for forming a convolute paper tube on a winding mandrel, including means for conveying a sheet of paper from a gluing and cutting apparatus longitudinally of the winding mandrel, with an edge of the paper sheet engaged in a longitudinal slot in the mandrel, to a position where the sheet edge is fully engaged with the mandrel suitably for winding. The conveying means includes a belt conveyor for slidable frictional engagement of the paper sheet to convey the paper sheet into winding position while being slidable with respect thereto so that the paper can remain in proper winding position while in continuing contact with the moving conveyor belt. Support wires, guides, trim rolls, and a stop are also provided in the apparatus for controlling the pick up, transport, alignment, and terminal position of the sheet.
