Abstract
Abstract Webs including warp elements formed by multiply splitting an elongate sheet os plastics material are woven by disposing a warp beam carrying the unsplit sheet with its axis at an acute angle to the direction of the warp elements in the woven web so that the packing density of the elements in the web exceeds that of the elements as split from the sheet.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
111 words
A weaving loom for transforming sheet material into a woven web, comprising a. a warp beam for carrying a roll of sheet material, said warp beam being mounted for rotation about an axis; b. dividing means for dividing the sheet material into a plurality of strips; and c. forming means for forming said strips into a plurality of warp ends for the web, said warp ends all extending in a single predetermined direction inclined at an acute angle with the rotational Axis of the warp beam, whereby the packing density of the ends in said predetermined direction exceeds the packing density of the strips as they are divided from the sheet.
Claim 2
Dependent Claim
111 words
A weaving loom for transforming sheet material into a woven web, comprising a. a warp beam for carrying a roll of sheet material, said warp beam being mounted for rotation about an axis; b. dividing means for dividing the sheet material into a plurality of strips; and c. forming means for forming said strips into a plurality of warp ends for the web, said warp ends all extending in a single predetermined direction inclined at an acute angle with the rotational Axis of the warp beam, whereby the packing density of the ends in said predetermined direction exceeds the packing density of the strips as they are divided from the sheet.
Claim 3
Dependent Claim
35 words
The weaving loom claimed in claim 1, characterized by said sheet material being drawn from a plurality of warp beams of which the axes of rotation are inclined at acute angles to said predetermined direction.
Claim 4
Dependent Claim
29 words
The weaving loom claimed in claim 1, characterized in that the axis of said warp beam lies in a plane parallel to but displaced from that of said web.
Claim 5
Dependent Claim
27 words
The weaving loom claimed in claim 2, characterized in that the axis of each said beam lies in a different plane parallel to that of said web.
Claim 6
Dependent Claim
28 words
The weaving loom claimed in claim 2, characterized by including two said beams of which the axes are inclined at equal but opposite angles to said predetermined direction.
Claim 7
Dependent Claim
29 words
A weaving loom as claimed in claim 2, characterized by including a plurality of said warp beams disposed with their axes mutually parallel and in the same vertical plane.
Claim 8
Dependent Claim
58 words
A weaving loom as claimed in claim 1, wherein the forming means includes an eyelet bar pierced by a multiplicity of apertures and disposed in the plane of the web and at said acute angle to said predetermined direction, in that said warp material passes from said beam to said web through individual eyelets in said eyelet bar.
Claim 9
Dependent Claim
38 words
A weaving loom in accordance with claim 1 characterized by a further beam disposed with its axis perpendicular to said predetermined direction, and in that further warp filaments are led into said web from said further warp beam.
Claim 10
Independent Claim
95 words
The method of weaving a web including warp elements formed by splitting sheet material, said warp elements extending generally in a predetermined direction in said woven web, which comprises the steps of: a. disposing said sheet material in a roll mounted for rotation about an axis inclined at an acute angle to said predetermined direction; b. leading said sheet material from said roll to divider means whereby said sheet is longitudinally divided into a multiplicity of said warp elements; and c. leading said warp elements through individual apertures in an eyelet bar into said web.
Claim 11
Independent Claim
95 words
The method of weaving a web including warp elements formed by splitting sheet material, said warp elements extending generally in a predetermined direction in said woven web, which comprises the steps of: a. disposing said sheet material in a roll mounted for rotation about an axis inclined at an acute angle to said predetermined direction; b. leading said sheet material from said roll to divider means whereby said sheet is longitudinally divided into a multiplicity of said warp elements; and c. leading said warp elements through individual apertures in an eyelet bar into said web.
Claim 12
Dependent Claim
30 words
The web weaving method of claim 9 wherein the sheet material is made of polyethylene film having a width of approximately 1 meter and a thickness of approximately 25 microns.
Claim 13
Dependent Claim
26 words
The web-weaving method of claim 9 wherein the width of the woven web is not greater than one-hundredth that of the sheet material forming the warp.
Claim 14
Dependent Claim
27 words
The web-weaving method of claim 9 wherein the width of the woven web is not greater than one two-hundredth that of the sheet material forming the warp.
