Provided is a glass film-resin composite body which makes it possible to obtain a long-length (e.g., 500 m or more-long) glass roll. The glass roll with resin film comprises a glass film, and a resin film laminated to at least one surface of the glass film through an adhesive, wherein a creep amount a of the adhesive is 50 m or less, as measured after applying a tensile shear load per unit area of the adhesive of 5 g/mm.sup.2, to the resin film for 48 hours, in a state in which the glass film is fixed in 23 C. and 50% RH.

The invention relates to a method of winding and packaging wide wallpaper, which is wound around a roll on a winding and rotary device, followed by packaging wallpaper in containers for transportation or storage. In the first embodiment of the invention, in the presented process, winding of the wallpaper (3) is carried out onto a winding and rotation mechanism, made in the form of a finished hollow closed cylindrical tube (1) of flexible material, equipped with a valve (2) for supplying and discharging air from it. At the same time, the valve (2) is fixed on one of the tube bases (4). Along the length of the pumped cylindrical tube (1) is fixed the edge of the wallpaper (3) and wound it on the tube (1) until a roll of the required length is obtained. In the second embodiment of the invention, the tube for wallpaper winding is formed from a part of a whole piece of wallpaper material (6) separated from the edge (7) in the form of a fold along the width of the wallpaper. The selected part of the wallpaper material, corresponding to the diameter of the tube (9) being created, is laid in width in two layers and fastened along the perimeter of the formed sides. The valve (10) is installed on one of the bases of the cylindrical tube (9) formed when air is pumped. The rest of the whole piece of wallpaper is wound on the tube (9) until a roll of the required length is obtained. Further, in both embodiments of the described method, the air is released from the tube through the valve to form a flat rectangular structure in the form of wallpaper layers with a tube placed inside. The resulting structure is laid into several layers for packaging in containers and subsequent storage and transportation. Flexible materials such as paper, vinyl, PVC, polyethylene and others are used as material for the manufacture of the tube.

Winding apparatuses for winding sheet material and related methods are disclosed herein. The winding apparatuses can include a set of winding drive rollers. Each drive roller of the winding drive rollers can have drive wheels spaced apart along the respective drive roller with a winding zone between the winding drive rollers. The winding apparatus can also include a feed system positioned before the set of the winding drive rollers for moving sheet material along a travel path in a machine direction into the winding zone.

The present invention provides rolled products, such as spirally wound rolls of bath tissue comprising a plurality of separably joined sheets, that may be repeatably and reliably dispensed by a user with a single hand. Single handed dispensing of the rolled products is facilitated by the web having a ratio of detach strength, typically having units of grams (g) to cross-machine direction (CD) tensile, having units of grams per 76.2 mm, of 0.65 or less, such as from about 0.10 to 0.65. In this manner rolled bath tissue products may have a CD tensile from about 400 to about 1,000 g/76.2 mm and a detach strength from about 100 to about 500 g.

Production of a passivation layer from at least one mass, the mass forming a tearable protective layer for a first side surface of an adhesive roll after drying and/or after a chemical reaction. Performing the passivation of a side surface of an adhesive roll more quickly and also in a simpler manner is provided by a method having the following steps: a) applying at least one first layer of the mass to a surface or to both surfaces of a production base for the passivation element, the layer adhering to the production base; b) at least partially drying and/or curing the layer to form a passivation layer. Production of a passivation element by a passivation layer is achieved by at least one of the following steps: cutting the passivation layer to size with or without the production base and/or removing part of the passivation layer from the production base as the passivation element.

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.
