Abstract
The invention resides in a system and method of tensioning a net comprising a frame having at least two opposing frame members and a net extending therebetween. The net is made from material of cords of a water soluble yarn capable of high shrinkage rates when wetted with water and dried. A tensioning device may be provided along one of said frame sides for causing tensioning of localized regions in said mesh after said mesh is wetted with water. The invention further resides in a method of tensioning a net to a frame having at least two opposing frame members and the net extending therebetween such that by sizing the net larger than said frame and mounting the net onto the frame such that the border is located outside of the frame and wetting the net and allowing it to dry, the net shrinks around the frame taking up play otherwise existing prior to the wetting step.
