Abstract
Abstract A resin cladding is extruded onto a base strip 10 that is assembled into a cushioned automotive pull strap handle. This is done by feeding a continuous length of base strip 10 through an extrusion mold 12 that forms a continuous resin cladding 13 surrounding base strip 10 and providing raised shoulders 15 extending along longitudinal side edges of strip 10. Discrete strips 30 are cut from continuous strip 10 and resin cladding 13 is cut and stripped away from end regions 31 of discrete strips 30. Apertures 33 are punched in end regions 31 and discrete strips 30 are assembled into strap handles. Resin cladding 13 can also be cut and stripped away from end regions 31 before discrete strips 30 are cut from continuous strip 10.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
111 words
A method of extrusion cladding onto a base strip for assembly into a cushioned automotive pull strap handle, said method comprising: a. feeding a continuous length of said base strip through the die of an extrusion coating means; b. extrusion cladding a resin material surrounding said base strip and providing raised shoulders extending along longitudinal side edges of said strip; c. cutting discrete strips from said continuous strip; d. cutting and stripping away said resin material of said cladding from end regions of said discrete strips; e. punching apertures in said end regions for said discrete strips; and f. assembling said discrete strips within a cover to form said strap handles.
Claim 2
Independent Claim
111 words
A method of extrusion cladding onto a base strip for assembly into a cushioned automotive pull strap handle, said method comprising: a. feeding a continuous length of said base strip through the die of an extrusion coating means; b. extrusion cladding a resin material surrounding said base strip and providing raised shoulders extending along longitudinal side edges of said strip; c. cutting discrete strips from said continuous strip; d. cutting and stripping away said resin material of said cladding from end regions of said discrete strips; e. punching apertures in said end regions for said discrete strips; and f. assembling said discrete strips within a cover to form said strap handles.
Claim 3
Dependent Claim
41 words
The method of claim 1 including cutting said discrete strips while said continuous strip advances from said extrusion coating means, and stripping said resin and punching said apertures while said discrete strips advance along a path transverse to said continuous strip.
Claim 4
Dependent Claim
36 words
The method of claim 1 including incorporating a blowing agent into a portion of said resin material of said cladding on the side of said continuous strip opposite said raised shoulders to provide a foamed cushion.
Claim 5
Dependent Claim
17 words
The method of claim 1 including recycling and reextruding said resin material stripped from said end regions.
Claim 6
Dependent Claim
41 words
The method of claim 4 including cutting said discrete strips while said continuous strip advances from said extrusion coating means, and stripping said resin and punching said apertures while said discrete strips advance along a path transverse to said continuous strip.
Claim 7
Dependent Claim
36 words
The method of claim 5 including incorporating a blowing agent into a portion of said resin material of said cladding on the side of said continuous strip opposite said raised shoulders to provide a foamed cushion.
Claim 8
Independent Claim
121 words
A method of extruding cladding onto a base strip for assembly into a cushioned automotive pull strap handle, said method comprising: a. feeding a continuous length of said base strip through the die of an extrusion coating means; b. extrusion cladding a resin material surrounding said base strip and providing raised shoulders extending along longitudinal side edges of said strip; c. cutting and stripping away said resin material of said cladding from end regions of discrete strips to be cut from said continuous strip; d. cutting said discrete strips from said continuous strip in said end regions where said resin material of said cladding is stripped away; and e. assembling said discrete strips within a cover to form said strap handles.
Claim 9
Independent Claim
121 words
A method of extruding cladding onto a base strip for assembly into a cushioned automotive pull strap handle, said method comprising: a. feeding a continuous length of said base strip through the die of an extrusion coating means; b. extrusion cladding a resin material surrounding said base strip and providing raised shoulders extending along longitudinal side edges of said strip; c. cutting and stripping away said resin material of said cladding from end regions of discrete strips to be cut from said continuous strip; d. cutting said discrete strips from said continuous strip in said end regions where said resin material of said cladding is stripped away; and e. assembling said discrete strips within a cover to form said strap handles.
Claim 10
Dependent Claim

Claim 12
Dependent Claim
36 words
The method of claim 7 including incorporating a blowing agent into a portion of said resin material of said cladding on the side of said continuous strip opposite said raised shoulders to provide a foamed cushion.
Claim 13
Dependent Claim
16 words
The method of claim 10 including forming apertures in said end regions of said discrete strips.
Claim 14
Dependent Claim
17 words
The method of claim 11 including recycling and reextruding said resin material stripped from said end regions.
