Abstract: The disclosure is for an apparatus and a method of adhering particulate matter to limited areas of adhesive on a moving web and enabling the use of a very limited amount of particulate matter so that material costs are minimized. The path of a moving web with zones of adhesive and with previously supplied loose particles is shaped to form a trough with substantially vertical sides, so that gravity clears the web of excess material as the web moves down and up through the trough. Meanwhile, the particles falling from the web, go into the bottom of the trough where they stay until they stick to a following portion of the web which has adhesive. The loose particles are thereby immediately recycled for use, without any exposure to other contaminating materials, and the amount of particulate material used approaches the ideal quantity which would be needed to cover only the adhesive areas.

The grip is usable in rainy conditions.
