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 invention relates to a holding system for holding sheet material for plotters characterized in that it comprises at least one substantially tubular side holding element (1), at least part of the external surface (2) thereof being tapered. Furthermore, said side holding element (1) comprises a longitudinal opening (7) and has internal chamfers at one of its ends (4). As a result of the thickness and the tapering of the external surface thereof, the side holding element hold the sheet material and, simultaneously, ensures that there is a gap between the winder tube and the sheet material wound on said tube, which facilitates its removal from the tube.

A core prevents a battery separator wound there a round from moving and becoming misaligned on an outer circumferential surface of the core in a widthwise direction of the core. The core allows a separator to be wound around the outer circumferential surface thereof and is made of resin. The core includes a groove formed on the outer circumferential surface thereof, the groove extending in a direction substantially equivalent to a circumferential direction of the outer circumferential surface.

A coiling device includes a coiler (1) having a coiling mandrel (3) for coiling a metal strip (2) which is fed (x) to the coiler (1), and a coiling swing arm (4) having a front and a rear pressure roller (5, 6) and a deflection plate (7). A swing arm drive (8) lines up the coiling swing arm (4) with the coiling mandrel (3) and is driven away from the coiling mandrel (3). An upper duct flap (9) upstream of the coiler (1) in the feed direction (x) for guiding the metal strip (2). A flap drive (10) for positioning the upper duct flap (9) such that, when the coiling swing arm (4) is lined up with the coiling mandrel (3), the upper duct flap is arranged between the coiling mandrel (3) and the front pressure roller (5) of the coiling swing arm (4) or is arranged upstream of the front pressure roller (5) of the coiling swing arm (4). In the first-mentioned case, the metal strip (2) is deflected around the coiling mandrel (3) only by the rear pressure roller (6) and the deflection plate (7) of the coiling swing arm (4) and, in the last-mentioned case, additionally also by the front pressure roller (5).

Provided is a glass roll (1), including: a winding core (2); a film body (F), which is taken up into a roll shape by the winding core (2), and includes a glass film (3) and a scattering prevention film (7) having a smaller width than the glass film (3); and flanges (8) which are mounted to the winding core (2), and which are arranged on both sides of the film body (F) in a width direction. The film body (F) includes a detachable displacement prevention film (6) on a termination end portion side of the glass film (3) in a take-up direction. The displacement prevention film (6) includes a wide portion (6a) having a lager width than the glass film (3).

The invention pertains to the field of industrial machinery for converting paper and/or for processing strip materials, and relates to a paper mill rewinder for forming reels of paper strip material, in particular, but not exclusively, tissue paper, of conventional or structured type, non-woven, TAD (Through Air Drying), or other similar materials characterized by having a very light weight and low density, with continuous, or non-stop, reel change device. Said rewinder (1) comprises: a supporting frame (3); feed means (4) for a winding rod (A); a main forming cradle (C1) for a reel (B) around said winding rod (A), comprising a first (5) and a second (6) winding roller; means for unloading (7) said reel (B) once formed; a control unit, a secondary pre-forming cradle (C2) for said reel (B), comprising a third winder roller (8) and lateral supporting means for said reel (B); means for transferring said reel (B) from said secondary pre-forming cradle (C2) to said main forming cradle (C1), where said transfer takes place without interruption to the winding, of the strip (N) onto said rod (A).

The invention relates to a method for introducing a material web into a corrugating device having a corrugating roller for generating from the material web a corrugated web. The method comprises the step of attaching at least one double-sided adhesive tape piece which has a first adhesive face and a second adhesive face that is opposite the first adhesive face to the material web by means of the first adhesive face upstream of the corrugating device of the material web, and guiding the material web through the corrugating device in such a manner that the second adhesive face adheres to the rotating corrugating roller while entraining the material web for introducing the material web.

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.

Said rewinder (1) comprises: a supporting frame (3); feed means (4) for a winding rod (A); a main forming cradle (C1) for a reel (B) around said winding rod (A), comprising a first (5) and a second (6) winding roller; means for unloading (7) said reel (B) once formed; a control unit, a secondary pre-forming cradle (C2) for said reel (B), comprising a third winder roller (8) and lateral supporting means for said reel (B); means for transferring said reel (B) from said secondary pre-forming cradle (C2) to said main forming cradle (C1), where said transfer takes place without interruption to the winding, of the strip (N) onto said rod (A).

Improved object wrapping materials exhibiting a number of beneficial properties to overcome prior deficiencies are provided. Such properties include the inclusion of a separation interface overlay that allows for greater rigidity at the leading and trailing edges of such wraps. Also, the inclusion of shear-reducing wrap material portions is described, as well as recoil reduction structures within the leading edge regions. Furthermore, core adhesive additions allow for greater resiliency to the base wrap material as it unwinds therefrom, reducing potential waste wrap products by permitting greater amounts of wrap materials in use. Other considerations include the ability, through proper configuration designs, to position a wrap separation indicator within a certain range of distances from the trailing edge, thereby providing greater reliability of wrap application device disengagement during wrap application. Such benefits are thus supplied individually and in tandem for improved versatility and utility of such wrap materials.
