Abstract
This invention describes a hook design for the hook portion of a hook and loop fastener system, and the hook strip made up of a multiplicity of such hooks projecting from a common base. The hook design encompasses a thickened stem portion projecting from the base and connecting to lobes of a crook portion at a neck. The stem portion is substantially thicker than the crook portion and terminates at the neck. The lobes and the stem are tapered whereby the hook can be easily withdrawn from its mold cavity during the molding operation. The hook is characterized by improved engageability and closure performance.
