Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
145 words
Apparatus for extruding a unitary strip with a plurality of spaced cords including an extruder screw, a die operatively associated with said screw separable into a portion including cord guiding means and a portion including strip sizing means, said cord guiding means having a plurality of spaced openings disposed in a single plane, said strip sizing means including movable members disposed in a single plane defining the thickness of said strip and a movable member disposed adjacent to said other members defining the width of said strip, means for adjusting the position of said movable members with respect to each other to change the dimensions of the opening through said strip sizing means, and said cord guiding means and said strip sizing means defining a cavity for the flow of plastic material around spaced cords advancing through said die to deliver therefrom a unitary strip.
Claim 2
Dependent Claim
