Abstract: An improved paper band delivery assembly for reliable high speed delivery of a turn-up paper band across a moving web of paper being wound onto a spool. The turn-up paper band is made ready for a turn up procedure by coiling a predetermined length of paper band suitable for a particular machine and retaining the coiled paper band in a reservoir pending deployment across a spool for a turn up procedure. The paper band may be coiled via manual operation or via automated operation. Coiling apparatus may be modularly replaced on a paper making machine. The coiled paper band may be supported within the reservoir on rollers, pins, or other items conducive to fast and reliable uncoiling.

Abstract: A core for winding sheet material is proved. The core comprises a cylindrical tube having a longitudinally oriented slot formed therein, and a strip of soft material located in the slot. Because of the geometry of the slot and the strip, the strip may be softer in the central region but firmer where the core transitions from the relatively soft strip to the relatively hard tube. The leading edge of the sheet material imbeds itself into the soft central region of the strip as additional layers are wound around the core.

Abstract: A machine (1) includes an unwinding section (3) for unwinding parent reels (Ba, Bb) of web material (N), an unwinding section (3) for unwinding parent reels (Ba, Bb) of web material (Na, Nb), and at least one winding station (15). The winding station in turn includes a winding device (41, 51), to which a longitudinal strip (S) of web material is fed. In the winding station, a respective spool (B) of web material is formed. The winding station (15) further includes: a cutting device (81, 83) for the longitudinal strip (S), to cut the longitudinal strip (S) transversely, thus forming a tail edge, which remains on the spool (B) under formation, and a leading edge; and a holding device (85) for holding the leading edge of the longitudinal strip (S), to transfer the leading edge onto a tubular winding core (T) of a new spool to be wound.
