Abstract
Abstract The invention relates to a method of forming a shoe lining. The aim of the invention is to produce a shoe lining which can be connected to the upper and accurately brought into line with the regions of the foot which are to be protected more simply and cheaply than has been possible heretofore. This aim is accomplished by forming a shoe lining comprising providing a web of material including a first layer of weldable foam material and a second dense layer of weldable material overlying the first area, effecting a pressing and heating treatment over a substantial area of the first layer to fuse the foam and make this area dense, while leaving a portion of the first layer untouched to form a cushion.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
103 words
A method of forming a shoe lining from a web of material including a first layer of weldable foam material and a second dense layer of weldable material overlying said first layer, the improvement to effect a pressing and heating treatment over a substantial area of said first layer to fuse the foam and make this area dense, while leaving a portion of the first layer untouched to form a cushion, wherein said web is formed by heating a foaming material in a mould to provide said first layer, and said second layer being formed by fusing at the wall of the mould.
Claim 2
Independent Claim
103 words
A method of forming a shoe lining from a web of material including a first layer of weldable foam material and a second dense layer of weldable material overlying said first layer, the improvement to effect a pressing and heating treatment over a substantial area of said first layer to fuse the foam and make this area dense, while leaving a portion of the first layer untouched to form a cushion, wherein said web is formed by heating a foaming material in a mould to provide said first layer, and said second layer being formed by fusing at the wall of the mould.
Claim 3
Independent Claim
94 words
A method of forming a shoe lining from a web of material including a first layer of weldable foam material and a second dense layer of weldable material overlying said first layer, the improvement to effect a pressing and heating treatment over a substantial area of said first layer to fuse the foam and make this area dense, while leaving a portion of the first layer untouched to form a cushion, wherein the pressing and heating operation is effected by a combined punching and welding tool which simultaneously punches the lining from the web.
Claim 4
Independent Claim
94 words
A method of forming a shoe lining from a web of material including a first layer of weldable foam material and a second dense layer of weldable material overlying said first layer, the improvement to effect a pressing and heating treatment over a substantial area of said first layer to fuse the foam and make this area dense, while leaving a portion of the first layer untouched to form a cushion, wherein the pressing and heating operation is effected by a combined punching and welding tool which simultaneously punches the lining from the web.
Claim 5
Independent Claim
92 words
A method of forming a shoe lining from a web of material including a first layer of weldable foam material and a second dense layer of weldable material overlying said first layer, the improvement to effect a pressing and heating treatment over a substantial area of said first layer to fuse the foam and make this area dense, while leaving a portion of the first layer untouched to form a cushion, wherein a material web, such as tricot, is positioned on the side of said first layer remote from said second layer.
Claim 6
Independent Claim
92 words
A method of forming a shoe lining from a web of material including a first layer of weldable foam material and a second dense layer of weldable material overlying said first layer, the improvement to effect a pressing and heating treatment over a substantial area of said first layer to fuse the foam and make this area dense, while leaving a portion of the first layer untouched to form a cushion, wherein a material web, such as tricot, is positioned on the side of said first layer remote from said second layer.
Claim 7
Independent Claim
118 words
A method of constructing a shoe upper provided with a lining in the heel zone from a web of material including a first layer of weldable foam material and a second dense layer of weldable material overlying said first area, comprising the following steps: a. effecting a pressing and heating treatment over a substantial area of said first layer to fuse the foam and make this area dense, while leaving a portion of the first layer untouched to form a cushion; b. connecting said area to the exterior of the upper, near the top edge of the heel zone thereof; and c. folding said lining inwardly so that the cushion lies within the heel area of the upper.
Claim 8
Independent Claim
118 words
A method of constructing a shoe upper provided with a lining in the heel zone from a web of material including a first layer of weldable foam material and a second dense layer of weldable material overlying said first area, comprising the following steps: a. effecting a pressing and heating treatment over a substantial area of said first layer to fuse the foam and make this area dense, while leaving a portion of the first layer untouched to form a cushion; b. connecting said area to the exterior of the upper, near the top edge of the heel zone thereof; and c. folding said lining inwardly so that the cushion lies within the heel area of the upper.
Claim 9
Independent Claim
91 words
A method of constructing a shoe upper provided with a lining in the heel zone from an integral web of material including a first layer of weldable foam material and a second dense layer of weldable material overlying said first area, comprising the steps of effecting a pressing and heating treatment over a substantial area of said first layer to fuse the foam and make this area dense, while leaving a portion of the first layer untouched to form a cushion; and connecting said area to the exterior of the upper.
Claim 10
Independent Claim
91 words
A method of constructing a shoe upper provided with a lining in the heel zone from an integral web of material including a first layer of weldable foam material and a second dense layer of weldable material overlying said first area, comprising the steps of effecting a pressing and heating treatment over a substantial area of said first layer to fuse the foam and make this area dense, while leaving a portion of the first layer untouched to form a cushion; and connecting said area to the exterior of the upper.
Claim 11
Dependent Claim
13 words
A method according to claim 5 in which said second layer is non-porous.
Claim 12
Dependent Claim
39 words
A method according to claim 5 in which said web is formed by heating a foaming material in a mould to provide said first layer, and said second layer being formed by fusing at the wall of the mould.
Claim 13
Dependent Claim
30 words
A method according to claim 5 in which the pressing and heating operation is effected by a combined punching and welding tool which simultaneously punches the lining from the web.
Claim 14
Dependent Claim
28 words
A method according to claim 5 in which a material web, such as tricot, is positioned on the side of said first layer remote from said second layer.
Claim 15
Dependent Claim
20 words
A method according to claim 5 in which the fused dense area of said first layer completely surrounds the cushion.
