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. A method is provided for feeding paper sheets to a convolute paper tube winding mandrel including the steps of feeding the end of a web of paper into slidable frictional engagement with a conveyor belt, cutting the web at a predetermined length from the end to form a sheet of paper and release the sheet for transport by the conveyor, transporting the sheet by slidable frictional engagement with the conveyor longitudinally of the elongated winding means while in side-edgewise engagement with a longitudinal slot therein, and halting the sheet while in full length edgewise engagement with the elongated winding means.
