Abstract
Abstract An L-shaped extruded edge-protector section for the strapping of articles, stacks or the like, has along the inner or outer surfaces of the respective flanges, respective adhesive strips while the opposite surfaces having longitudinal recesses so that when the edge-protectors are stacked, the adhesive strips are received with clearance in the recesses of adjacent edge-protectors. The edge-protectors when stacked thus do not adhere to one another even though masking strips are not provided for the adhesive strips.
