A method of grooving a durable transfer roll core may comprising loading the durable transfer roll core onto a grooving apparatus and grooving a main surface of the durable transfer roll core via engagement with one or a plurality of cutting tools of the tooling section of the grooving apparatus.

A roll and a method for producing a roll which are capable of effectively preventing tunneling are provided. A roll includes a core having a tubular shape and a laminate wound around the core. The laminate includes a process film, a surface coat layer, a substrate layer, an adhesive layer, and a release liner, in this order, in a laminating direction. The process film is formed from at least one member selected from polyethylene terephthalate (PET), polyolefins, and polyvinyl chloride (PVC). The surface coat layer is formed from a fluorine resin. The release liner is formed from polyethylene terephthalate (PET). The core is formed from an acrylonitrile-butadiene-styrene copolymer resin (ABS) or polypropylene (PP).

Disclosed is a tubular core on which sheets of metal or other material can be wound and supported, for shipment, handling and dispersal, and a method for forming the core. The core comprises a metal sheet or strip which has a rectangular-ribbed cross-sectional profile comprising rectangular, flat ribs, and which is wound spirally into a tubular configuration. The core is formed by passing the strip through a plurality of roll-forming stands, to progressively form sections of the ribs and progressively define the sections into the rectangular ribbed profile in which the flat ribs collectively form a support surface for the sheets which are to be wound on the core.

The present disclosure is directed to a core-roll that contains areas of anti-slip material and methods of making the core-roll. The core-roll has one or more anti-slip zones to allow a continuous paper web to be wound around the core without the need for additional physical restraint to keep the paper from shifting laterally along the core. In another embodiment, the disclosure describes a parent roll having an anti-slip core-roll that does not interfere with other operations that occur during converting.

An improved core for mounting on one or more core engaging elements such as a pair of chucks and a method of making an improved core are provided. The core is adapted to wind and unwind material thereon. The core may comprise a high coefficient of friction coating disposed on the inner surface of the core to improve the core-chuck interaction. The inner surface may be mechanically or chemically treated to improve core-chuck interaction.
