Disclosed is a cutting apparatus for a roll zebra. The cutting apparatus includes: a main body portion; a mounting portion provided at one side of the main body portion to wind or unwind a fabric; a cutting portion provided at one side of the main body portion to cut the fabric with a required length; and a discharge portion provided at one side of the main body portion to convey the fabric cut by the cutting portion to the outside. The cutting portion includes a longitudinal cutting portion cutting the fabric in a longitudinal direction, and a transverse cutting portion cutting the fabric in a transverse direction.

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 packaged flexible film is described. The packaged flexible film includes (i) a cylindrical core having an outer surface; (ii) a supply of flexible film wound about the core with a leading edge adjacent the outer surface and forming a connection ridge along the outer surface; and (iii) a cover strip comprising a compressed compressible cover material covering said connection ridge. Also described are a packaging system for flexible film and a multilayer flexible film packaging tape.

A dispenser housing for dispensing a multi-layer tape transfer tape used in a paper web turn-up operation, the transfer tape being the combination of a tape substrate coated on one side with a web grabbing adhesive and on the other side with a mounting adhesive and an affixed cord or cordlike feature, and a release liner having a release liner substrate fully coated on a first side with a release layer and zone-coated on a second side with a release layer, the transfer tape being wound onto a single spool with the release liner facing inward and the mounting side adhesive facing outward, such that buckling is precluded when the transfer tape is unwound from the spool.

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 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.

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.

Equipment for removing paper from parent reels used for the production of paper logs of paper material, including a support system adapted to support an exhausted parent reel, where the exhausted parent reel includes a tubular core on which residual paper to be removed is wound, and including removal capabilities for removing the residual paper from the core when the exhausted parent reel is placed on the support system. The removal capabilities include a suction cylinder having a horizontal axis onto which the paper is transferred by effect of the contact between the suction cylinder and the exhausted parent reel and by effect of the rotation of the suction cylinder around the horizontal axis.
