A roll of grid material for mine roof support, and a mining machine in combination with such a roll, in which the roll has bands of adhering material injected or otherwise forced into the roll in spaced locations along the roll's width. The adhering material interconnects the overlapped layers within the roll and is sufficiently strong to hold the grid material in the rolled configuration for transport and storage, and yet is readily pulled apart in response to sufficient manual or mechanical pressure applied against the roll, or tension applied to the unwound portion thereof, so as to enable the grid material to be incrementally unwound and installed in the mine. The rolls can be installed using a range of mining machines without need for any specialized dispensing or other apparatus mounted on the machine and without the need for any mechanical device to control unwinding.

The invention relates to a rolled up thin glass composite comprising a thin glass film and at least one further layer (10, 11, 20, 30) applied over the surface of one side of the thin glass film, wherein the at least one further layer (10, 11, 20, 30) is applied to a radially outer side of the rolled up thin glass film and the at least one further layer (10, 11, 20, 30) contains a desiccant which protects the thin glass film against stress corrosion cracking. The invention also relates to a method for storing a thin glass film by providing a thin glass film, applying at least one further layer (10, 11, 20, 30) over the surface of at least one side of the thin glass film, wherein a desiccant which protects the thin glass film against stress corrosion cracking is added to the at least one further layer (10, 11, 20, 30) and a thin glass composite composed of the thin glass film and the at least one further layer (10, 11, 20, 30) is rolled up in such a way that the at least one further layer (10, 11, 20, 30) is applied to a radially outer side of the rolled up thin glass film.

A stretch film supply roll used in stretch wrapping palletized loads includes a plurality of lengths of stretch film wound into a roll form and joined to one another using a plurality of lap seals that forms a continuous web of stretch film on the roll form. Such a stretch film supply roll may be useful, for example, in reuse applications where stretch film is reused multiple times to wrap different loads. In some instances, the lengths of stretch film may have been used to previously wrap different loads, and in some instances, the lengths of stretch film may have differing characteristics such as materials and/or thicknesses.

The present application describes a roll of paper products that may be compressed and subsequently provided in a non-circular dispenser. The roll of paper products is coreless, rolled with a specific tension and has a specific center diameter so as to enable individual paper products to be dispensed from the center of the roll even when compressed.
