Abstract
A plastic spacer/riser to increase useable height of a reclosable fastening system, such as 3M™ Dual Lock™ or Velcro® hook and loop products. The spacer/riser is adapted to be held in place on an external substrate with hot-melt glue, sonic welds, pressure-sensitive adhesives, acrylic foam tape, or screws.
Claims20
A method of fabricating a riser/spacer device, comprising the steps of:
- softening plastic in an extruder as said plastic is forced though said extruder by an extruder screw toward a die;
- shaping said softened plastic in said die;
- holding the shape of said plastic with shaping tooling and guides as said softened shaped plastic exits said die in a continuous length until said softened shaped plastic is cooled and set to a required shape and dimensions of said riser/spacer device;
- and
- maintaining the size of the plastic riser/spacer device by a ratio between the amount of plastic being forced through said die and the speed of a haul off apparatus pulling the plastic riser/spacer device away from said die and through shaping tooling and guides.

A riser/spacer device for use with a reclosable fastener, comprising, in combination:
- a riser/spacer device a having a first predetermined overall height, and first and second predetermined portions;
- said riser/spacer device having a rectangular structure including at least one hollow portion which extends the complete length of said rectangular structure parallel to the central elongated longitudinal axis of said rectangular structure;
- a reclosable fastener having a second predetermined overall height, and selectively closable and releasable first and second mating portions;
- said reclosable fastener comprises strips of flexible plastic covered with interlocking heads which fasten securely when pressed together;
- said first mating portion of said reclosable fastener being secured to said first predetermined portion of said riser/spacer device;
- said first predetermined overall height of said riser/spacer device plus and said second predetermined overall height of said reclosable fastener being determined by a gap to be filled between first and second substrates;
- said second predetermined portion of said riser/spacer device being connected to said first substrate;
- and
- said second mating portion of said reclosable fastener being connected to said second substrate.
