In a turn-up method for a reel-up for reeling of fiber webs, a web travelling in direction (S) is cut by two water jet nozzles moving in a transverse direction in relation to the web travelling direction (S). Two cuts (C1, C2) are formed by two water jet nozzles starting from the edges of the web (W) and moving to the web center where the cuts (C1, C2) cross or meet forming a V-shaped tail end (V1). After the cuts the movement of the water jet nozzles is stopped and after the return movement of the water jet nozzles, cutting is started again from the center toward the edges so that the web W is cut by two cuts (C3, C4) and a substantially V-shaped beginning end (V2) to the web W is formed and between the cuts (C1, C2) for the tail end (V1) and the cuts (C3, C4) for the beginning end (V2) there is formed one web reject part (R) with two substantially V-shaped cuts. A turn-up device for a reel-up for reeling of fiber webs has two water jet nozzles, in which the cutting by the water jet nozzles (10,12) may be stopped between cutting of a tail end (V1) and cutting of a beginning end (V2) for a selected time for forming only, wherein there is one reject part (R) in the turn-up and the cross-direction travel distance (L1, L2) of each nozzle is substantially shorter than the width (L) of the web (W).

The invention relates to a spool for winding a fibrous web, the lateral surface of which is formed by a coated spool core. The aim of the invention is to improve the winding quality by the fact that the outer lateral surface is formed by a plurality of separate coatings which are arranged axially next to one another, of which at least two adjacent coatings are made of different materials.

A machine forms a roll of convolutely wound web material. The machine includes a winding apparatus configured to receive a mandrel and the web material and wind the web material around the mandrel. A pulling device pulls the mandrel longitudinally to remove the mandrel from the roll after forming the roll. The machine further includes a restraint that engages the peripheral surface of the roll when the mandrel is pulled longitudinally to remove the mandrel from the roll. A method is also provided. In one aspect of the method, a web material is wound around a mandrel to form a roll of convolutely wound web material. The mandrel is pulled longitudinally after the step of winding the web material around the mandrel. The periphery of the roll is restrained from moving axially when the mandrel is pulled longitudinal. The mandrel is then removed from the roll.

A clasp is configured to engage an end of a tube. The clasp has a shaft that is insertable into a tube. The clasp includes a housing with clamping blocks that are spaced circumferentially around the shaft. The clamping blocks are moveable between a disengaged position in which the clamping blocks are spaced radially outwardly from the shaft at a distance sufficient such that a tube is insertable between the shaft and the clamping blocks, and an engaged position in which the clamping blocks are positioned radially inward of the disengaged position toward the shaft and are configured to press a tube disposed between the blocks and the shaft against the shaft. The clasp has at least one actuator engageable with at least one clamping block of the plurality of clamping blocks to move the at least one clamping block between the disengaged position and the engaged position.

The invention relates to a method of threading a fibrous web (W) onto a circular cylindrical object (3, 19) in a reel-up (2) for a paper-making machine (1). The reel-up (2) comprises an endless flexible belt (6) mounted for rotation along a predetermined path of travel. The endless flexible belt (6) is positioned adjacent the circular cylindrical object (3, 19) during winding and the fibrous web (W) residing on the outside surface (8) to engage the circular cylindrical object (3, 19) during winding such that the endless flexible belt (6) is deflected from the predetermined path of travel. When a fibrous web (W) is to be threaded onto the circular cylindrical object (3, 19), the circular cylindrical object (3, 19) is placed at a distance from the endless flexible belt (6) such that the endless flexible belt (6) is no longer deflected from the its path of travel. A narrow tail (17) is cut from a fibrous web (W) that is to be threaded and the narrow tail (17) is advanced on the outside surface (8) of the endless flexible belt (6). The circular cylindrical object (3, 19) is moved towards the endless flexible belt (6) such that the circular cylindrical object (3, 19) comes into contact with the narrow tail (17) and an adhesive substance is applied to the to the narrow tail (17) such that the narrow tail (17) will adhere to the circular cylindrical object and starts to be wound on the circular cylindrical object (3, 19), whereafter the narrow tail (17) is widened. The invention also relates to a reel-up (2) capable of carrying out the method.

A method for securing a web end of a paper web on a first drum during a change of drum, the method includes passing the web end through a nip between a Pope roller and the second drum and applying adhesive to an area of the web end on a downward-rotating area of the Pope roller after the web end is passed through the nip.

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.
