Abstract
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 so that the roll is self-resistant to unrolling. Also provided is a method of making such a roll including the steps of winding a length of polymeric mesh material into a roll and applying an adhering material to the mesh material. The adhering material has sufficient strength to hold the roll in a wound configuration and prevent the roll from free-wheeling or unwinding due to the roll's own physical properties.
