SPLIT HOOK FASTENER

摘要

The present invention provides a method for forming preferably a unitary polymeric hook fastener(20) comprising a flexible backing(22), and a multiplicity of spaced hook elements(9) projecting from the upper surface of the unitary backing(22). The hook elements(9) each comprise a stem portion(24) attached at one end to the backing(22), and a head portion(21) at the end of the stem portion(24) opposite the backing(22). The head portion(21) projects in different directions for some adjacent hook members(9) which adjacent hook members(9) each have a flat face(35,36) which flat faces(35,36) are mutually opposing in face to face relation.
