Abstract

See full text

A hook fastener portion including a thin strong flexible plate like backing and a multiplicity of resiliently flexible spaced hook members projecting at generally a right angle from an upper surface of the backing. The hook members each comprise a stem portion attached at one end to the backing and a head portion at the end of the stem portion opposite the backing that is flush with the stem portion on two opposite sides, projects past the stem portion on two opposite sides, and has a rounded surface opposite the stem portion to help the head portion enter between loops in a loop fastener portion. The hook members are more easily and firmly engaged with many types of loop fastener portions than the hook members on known commercially available hook fastener portions, in large part because they are very small compared to them, and the hook portions do not have an abrasive feel when contacted by a persons skin.
