Abstract
Abstract There is disclosed a syntehtic plastic sheet material having differentially colored bands made by a method which utilizes an extrusion die block having a chamber in which is disposed a pair of sleeve members. The matrix resin is supplied to the die block chamber and the differentially colored matrix resin flows towards the discharge openings from the sleeve members and encapsulates the differentially colored resin issuing therefrom. The bands of differentially colored resin are deposited at two different depths within the matrix resin with the bands at one depth being disposed in a first angular orientation and the bands at the second depth being at another angular orientation so that the bands appear to intersect and provide a grid pattern.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
154 words
Differentially colored extruded synthetic thermoplastic sheet material comprising a matrix of synthetic thermoplastic resin and a multiplicity of bands of differentially colored thermoplastic resin encapsulated therein, some of said bands extending at a first angular orientation relative to the longitudinal axis of said sheet material and at a first depth within said matrix, and the others of said bands extending at a second angular orientation relative to said longitudinal axis of said sheet material opposite to that of said first angular orientation and at a second depth within said matrix spaced from said first depth so as to visually appear to intersect with those of said first orientation when said bands are viewed through a face of said sheet material, a multiplicity of bands of each orientation being provided across the width of said sheet material, said bands being substantially uniform in area across the width of sheet material and substantially free from smearing.
Claim 2
Dependent Claim
154 words
Differentially colored extruded synthetic thermoplastic sheet material comprising a matrix of synthetic thermoplastic resin and a multiplicity of bands of differentially colored thermoplastic resin encapsulated therein, some of said bands extending at a first angular orientation relative to the longitudinal axis of said sheet material and at a first depth within said matrix, and the others of said bands extending at a second angular orientation relative to said longitudinal axis of said sheet material opposite to that of said first angular orientation and at a second depth within said matrix spaced from said first depth so as to visually appear to intersect with those of said first orientation when said bands are viewed through a face of said sheet material, a multiplicity of bands of each orientation being provided across the width of said sheet material, said bands being substantially uniform in area across the width of sheet material and substantially free from smearing.
Claim 3
Dependent Claim
53 words
The sheet material in accordance with claim 1 wherein the bands of one angular orientation are of a first color distinct from that of the matrix and the bands of the other angular orientation are of a color distinct from that of the matrix and of the bands of the first angular orientation.
Claim 4
Dependent Claim
16 words
The sheet material in accordance with claim 1 wherein said grind pattern provides a basketweave design.
Claim 5
Dependent Claim
21 words
The sheet material in accordance with claim 1 wherein the bands vary in appearance along the length of the sheet material.
