Abstract
Abstract An apparatus for making embossed strips of extruded thermoplastic resins such as vinyl resins to close manufacturing tolerances in which heated plastic is extruded in the form of a strip with an undercut portion or rib which must be controlled closely in its cross-sectional dimensions, the rib and adjacent surfaces of the strip being cooled by immersion in a bath of liquid while the remainder of the strip, in a plastic state, is passed in contact with an embossing roll to apply a pattern to it, the entire strip thereafter being cooled by immersion in a bath of liquid to prevent flow or recovery of the plastic from marring the pattern applied by the embossing roll.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
122 words
Apparatus for producing an article having a sharply defined pattern on at least one surface and a rib of predetermined crosssectional shape and dimensions on another surface thereof, comprising an extruder for extruding a continuous strip of heated thermoplastic resin having a rib on one side and an opposite surface, a container For cooling liquid adjacent to said extruder, a cover for said container for supporting said strip for sliding movement therealong and having a slot therein for receiving said rib for immersion in said liquid, a movable embossing member above said cover for engaging said surface of said strip, means containing cooling liquid for immersion of said embossed strip therein adjacent to the end of said cover remote from said extruder.
Claim 2
Dependent Claim
122 words
Apparatus for producing an article having a sharply defined pattern on at least one surface and a rib of predetermined crosssectional shape and dimensions on another surface thereof, comprising an extruder for extruding a continuous strip of heated thermoplastic resin having a rib on one side and an opposite surface, a container For cooling liquid adjacent to said extruder, a cover for said container for supporting said strip for sliding movement therealong and having a slot therein for receiving said rib for immersion in said liquid, a movable embossing member above said cover for engaging said surface of said strip, means containing cooling liquid for immersion of said embossed strip therein adjacent to the end of said cover remote from said extruder.
Claim 3
Dependent Claim
30 words
The apparatus set forth in claim 1 in which said embossing member is a roll having a pattern-forming periphery spaced from said cover and side flanges slidably engaging said cover.
Claim 4
Dependent Claim
17 words
The apparatus set forth in claim 2 in which said cover is composed of highly thermal-conductive metal.
Claim 5
Dependent Claim
133 words
Apparatus for producing a strip article from thermoplastic material having on at least one surface thereof a well-defined pattern, comprising: means for extruding a heated continuous strip of said material; means for supporting a first portion of said strip remote from said one surface while said strip is still heated and for permitting relative movement of said strip as it is extruded, said means having an opening therein, means for contacting a second portion of said strip remote from said one surface through said opening in said supporting means with a fluid cooling medium for cooling at least said portion without substantially cooling said one surface; and means for embossing the pattern on said one surface while said first portion is supported by said supporting means and said one surface is still heated.
Claim 6
Dependent Claim
133 words
Apparatus for producing a strip article from thermoplastic material having on at least one surface thereof a well-defined pattern, comprising: means for extruding a heated continuous strip of said material; means for supporting a first portion of said strip remote from said one surface while said strip is still heated and for permitting relative movement of said strip as it is extruded, said means having an opening therein, means for contacting a second portion of said strip remote from said one surface through said opening in said supporting means with a fluid cooling medium for cooling at least said portion without substantially cooling said one surface; and means for embossing the pattern on said one surface while said first portion is supported by said supporting means and said one surface is still heated.
