A roll (10) of glass ribbon (20) and an interleaf material (40) disposed in alternating layers, wherein a layer of the interleaf material is pinned to an adjacent layer of the glass ribbon by an electrostatic force that is of a value so that a shear force required to cause slip between the interleaf material and the glass ribbon is greater than or equal to 10 times that required to cause slip between them when not electrostatically pinned together. Methods for winding and unwinding the roll, as well as an apparatus for winding the glass ribbon and interleaf material into a roll, are also disclosed.

Method for controlling the feed of semifinished products in a tyre building process, said method comprising: feeding a semifinished product (10) into a building station (30) adapted to build, through said semifinished product (10), a structural component of a tyre; performing, in an acquisition zone (AZ), a verification to verify the presence of at least one defect of said semifinished product (10); generating a notification signal (NS) as a function of said verification; activating, as a function of said notification signal (NS), a discard device (60), configured for discarding at least one portion of said semifinished product (10) comprising said at least one defect.

A rolled graphite sheet includes a rod-shaped body and a graphite sheet having a length of 1 m or more and a width shorter than the length. The graphite sheet is wound around the rod-shaped body and is rolled in a length direction. When a length direction-end of the graphite sheet is pulled with a force of 1.5 N/cm in a direction parallel to a tangent of a cross-sectional circle of the rolled graphite sheet while fixing the rod-shaped body, the end moves 5 mm or less in the direction parallel to the tangent of the circle.

A method of manufacturing a glass roll, includes: a forming step (S1) of forming, while conveying a glass film, the glass film by a downdraw method; a temporary rolling step (S3) of rolling the glass film while superposing a protective film on the glass film at a downstream end of a path of the conveying in the forming step (S1), to thereby manufacture a source glass roll; and a main rolling step (S4) of unrolling, while conveying the glass film to a downstream side, the glass film from the source glass roll, and then rerolling the glass film while superposing a protective film on the glass film at a downstream end of a path of the conveying, to thereby manufacture a glass roll. Higher tension in a rolling direction is applied to the glass film in the main rolling step (S4) than in the temporary rolling step (S3).

Systems and methods for batch processing glass substrate webs are disclosed. In one embodiment, a method of processing a glass substrate web includes applying a spacer layer to at least one of a first surface or a second surface of the glass substrate web, and rolling the spacer layer and the glass substrate web to form a spool. The spacer layer is configured such that a gap exists between the first surface and the second surface of the glass substrate web within the spool. The method further includes applying a fluid to the spool such that the fluid surrounds the spool and is disposed within the gap between the first surface and the second surface within the spool.

Web-wound rolls with a web edge treatment by printable adhesive compositions and processes to make the same are provided. The web-wound rolls include a substrate web having at least two web edges. One or more quantities of adhesive are disposed and subsequent curing adjacent to one or both of the web edges. The substrate web is wound upon itself in multiple revolutions about a central core, and each revolution is held substantially separate from the next by the adhesive.

A manually-operated dunnage conversion apparatus includes a housing with an outlet opening, a supply of slit sheet stock material supported within the housing for dispensing from the outlet opening, and a pair of opposed expansion members rotatably coupled to the housing for rotation about respective, parallel expansion axes between the supply and the outlet opening. The expansion members are biased towards each other via a biasing member to provide a gripping force on sheet stock material fed therebetween to apply friction to the sheet stock material that causes the sheet stock material to expand in length and thickness as an operator pulls the sheet stock material from the outlet opening in the housing. With the possible exception of the biasing member, the apparatus may be made of paper-based products, making the apparatus recyclable, reusable, and composed of a renewable resource, as well as inexpensive to manufacture.

A method and apparatus is disclosed for preparing release paper rolls of adhesive duct insulation material which are stackable and non-adherent to each other. The adhesive insulation material contemplated is the type used for sealing crevices and spaces in air cooling and leaking systems generally referred to as Heating, Ventilation and Cooling systems, or HVAC. The apparatus and method disclosed dispenses strips (16) of the adhesive insulation material onto release paper (20) generally silicone coated on at least one side, leaving a marginal tab (30) which is then bent upwardly to contact each alternate side face (32) of the insulation strips (16) to protect them from adhering to each other when placed in a shipping container. This system thus avoids the need for inserting a sheet of interface paper between the rolls to prevent them from sticking to each other.

A sheet material conveying device unwinds from a roll body a sheet-shaped member constituting a membrane electrode assembly and conveys the sheet-shaped member. The sheet material conveying device is equipped with a suction member that moves the sheet-shaped member, and a negative pressure supply unit that supplies a negative pressure to the suction member. The suction member is constituted by a porous body capable of sucking under the negative pressure one surface of the sheet material having been unwound from the roll body and is movable in a conveying direction.

A guide film supply mechanism feeds a guide film toward a winding mechanism. The guide film is a film in which a pair of supports, which is long in the longitudinal direction of a base film and is thicker than a product film, is disposed on both side portions of the upper surface of the base film that is formed to have a width larger than the width of the product film. A product film supply mechanism feeds the product film toward the upper surface of the guide film. The winding mechanism forms a film roll by winding the product film for each guide film. The tension of the product film is set to be smaller than the tension of the guide film.
