A wrapping paper is applied to the roll and crimped over interior roll headers inserted at the ends of the rolls. Grooves are cut along the side edges of the wrapping paper to reduce the amount of wrapping paper overlap and indentations in the ends of the paper rolls caused thereby.

Abstract: A tiltable table has a pneumatic actuator and a locking system for establishing and maintaining a table position. The locking system is operated by an air cylinder that engages a dog with a ratchet plate secured to the table. The ratchet permits the table to be raised but not lowered while locked. The ratchet must be unlocked before the table can be lowered. The dog is spring-biased to locking position, and is air-operated for release against the action of the biasing spring. On lowering the table, air from the actuator can be used to unlock the ratchet. The air can be permitted to escape through a restriction orifice at a slow enough rate to maintain sufficient air pressure to keep the locking system disengaged, but sudden release of all the air pressure will again permit the spring to re-lock the system to prevent a downward slamming of the table surface.

Abstract: A process for sealing roof seams in a corrugated sloped metal roof comprises applying elongated strips of a flexible hot melt thermoplastic bituminous composite material to the seams and the edges of the roof surface immediately adjacent thereto but not over the whole roof surface. The bituminous composite material has an elevated operating temperature of about 500.degree.-600.degree. F. or greater. The bituminous composite material is heated to at least a point wherein the material becomes soft and semi-molten so as to conform to the surface of the roof and the convolutions of the corrugations and bonds to the roof surface. Prior to applying the bituminous composite material, a compatible metal primer is applied to the roof seams. The bituminous composite material is troweled into shape while it is still hot. An alternative application method comprises applying the material between overlapping roof sheets.

Abstract: A shoe sole comprises an outsole having a recess formed in the upper surface and an insert formed of resilient material that fits in the recess. The insert has a plurality of longitudinally spaced, downwardly extending transverse ribs extending across the underside of the insert. The ribs are formed of at least two lengths, with longer ribs alternating with shorter ribs in a regular pattern along the longitudinal length of the insert. The ribs are formed in a wavy sinusoidal pattern across the width of the shoe and the individual ribs are formed in sinusoidal vertical patterns, so that each individual rib has downwardly extending portions of different lengths that repeat in a pattern across the width of the shoe. The varying lengths of the ribs provide a first cushioning rate for initial compression of the insert, while the shorter portion of the ribs provide a graduated increase in spring resistance upon further compression of the ribs.
