A surface winder includes first (20) and second (22) winding rolls for winding a web on a center member, a stationary surface (27) spaced from the first winding roll for rolling a center member on the stationary surface, and a pinch pad (24) for pinching the web against a pinch surface upstream of the center member (c) and thereby severing the web. The first winding roll is provided with a high friction surface, and only a short length of web needs to be stretched between the pinch surface (25) and the first roll to tension and sever the web. The severed web is wound on the center member (c) as the center member rolls on the stationary surface.

An apparatus and method for sharpening a disc blade includes a grinding wheel mounted on a housing. The housing is mounted on a drive shaft so that the housing rotates with the drive shaft but can move axially relative to the drive shaft. A transversely extending projection on the housing extends into a space between two axially spaced spacers on the drive shaft. A spring is positioned between each spacer and the projection for resiliently biasing the housing in an axial direction.

Infeed apparatus for multi-level delivery of convolutely wound logs which includes a plurality of log supporting wheels (38) rigidly mounted on a cross shaft (35) with each of the wheels having a periphery interrupted by a plurality circumferentially spaced inwardly extending pockets (41-44), alternate (42, 44) of the pockets being constructed for upper level delivery and the remaining for lower level delivery (41, 43), each of the pockets having a trailing rear wall (64, 72) extending radially outward and a forwardly extending flat wall, (66, 73) the lower level pockets additionally having a generally radially extending forward, leading wall (71).

A web-winding apparatus includes a winding roll for contacting a web, a camshaft which is axially mounted in the winding roll, and push rods which engage the camshaft and which are radially movable by the camshaft to latch and unlatch web-engaging devices on the winding roll. The web-engaging devices can include transfer pins, cutoff blades, and transfer pads. The camshaft is normally rotated at the same speed as the winding roll by a servo motor, and the camshaft is rotated relative to the push rods when the servo motor changes the speed of the camshaft relative to the winding roll.
