A roll of label web and method utilize a length of first label web having a plurality of longitudinally spaced adhesive-backed labels removably attached to a substrate wound around a tubular core in such a manner that a first and last label of the first label web are fully intact and usable. The leading and trailing ends of the first label web are cut between labels. The trailing end of the first label web is releasably attached to the core by double-sided releasable adhesive tabs that allow the trailing end of the first label web to pull free from the core for printing the last label. The leading end of the first label web is temporarily secured to the roll by adhesive tabs that are removable without damaging the first label of the first label web.

The present application relates to a tab roll replacing device and a winding apparatus. The tab roll replacing device includes an unwinding mechanism; a roll mechanism, including a transfer plate, a first floating clamping assembly, a second floating clamping assembly, and a first fixed clamping assembly; a cutting mechanism for cutting off a tab material strip clamped by the first floating clamping assembly and the first fixed clamping assembly, or the second floating clamping assembly and the first fixed clamping assembly; and a strip splicing mechanism for connecting the tab material strip output by the unwinding mechanism.

Improved apparatus and methods of operating a turn up apparatus on a paper machine to improve the performance of a paper machine turn up process is presented. The apparatus may include a cross track with an internal slot for a paperband to move upon and affixed a surface that is proximate to the first internal slot. The first apron may lie across a surface above a location for the paperband and interact with the paperband when the paperband is pulled out of the apparatus during a turn-up operation. An apron tensioning device may provide an additional force against an edge of a surface of the apron. A curved track may hold the paperband at an angle to an axis of the cross track, and the paperband feeding device may advance the paperband during a portion of a turn-up operation.

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.

A method for producing coreless roll paper includes a winding step in which paper 11 is wound on a shaft 20 in a roll shape, and an extracting step in which the shaft 20 is extracted from roll paper 12 to form a center hole 13. The shaft 20 includes a body part 22 having grooves 23, and a sleeve 30 is put on and fixed to the body part 22. In the winding step, the paper 11 is wound on the sleeve 30.

A paper tape turn-up construct including a cover flap and a multi-bend structure to both protect an adhesive layer and to build an optimized elevated structure to present the adhesive layer during initiation of the paper web turn up process. Methods and apparatus to form the constructs and apply the constructs to paper production equipment are also included. The multi-bend paper turn up construct includes layers of adhesive and pulpable substrate with strategically located release materials, such as silicon that enhance a bridging of a gap between a rotating paper web and an empty spool surface.

The invention relates to a winding machine for winding material webs, in particular foils or films, wherein the winding machine comprises a feeder system with a first belt feeder which, during the winding of the material web around a winding core in a first direction, wraps itself at least partially around the material web. The feeder system comprises a second belt feeder which is suitable for winding the material web in a second direction around the winding core.

The machine (1) comprises 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 comprises 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 comprises: a cutting device (81, 83) for the longitudinal strip (S), to cut the longitudinal strip (S) transversally, 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.
