Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
119 words
A method of manufacturing a welted article of footwear comprising the steps of attaching a sole-shaped board to one side of a flexible insole formed with an extended marginal portion so that the insole projects laterally beyond the board, securing an elongated projection on the other side of said insole to follow the contour of the edge of the insole but spaced inwardly therefrom, securing the projection to the inwardly pulled margin of a lasted upper and to the inner margin of a welt, and applying an outsole to the lasted upper-insole-welt unit, the sole-shaped board being detached from the insole subsequently to the securing of the projection to the upper and removed from the interior of the article.
Claim 2
Independent Claim
119 words
A method of manufacturing a welted article of footwear comprising the steps of attaching a sole-shaped board to one side of a flexible insole formed with an extended marginal portion so that the insole projects laterally beyond the board, securing an elongated projection on the other side of said insole to follow the contour of the edge of the insole but spaced inwardly therefrom, securing the projection to the inwardly pulled margin of a lasted upper and to the inner margin of a welt, and applying an outsole to the lasted upper-insole-welt unit, the sole-shaped board being detached from the insole subsequently to the securing of the projection to the upper and removed from the interior of the article.
Claim 3
Independent Claim
132 words
A method of manufacturing a welted article of footwear comprising the steps of temporarily attaching a stiff sole-shaped support board to one side of a soft flexible insole formed with an extended marginal portion so that the insole projects laterally beyond the board, securing an elongated flexible projection on the other side of the insole by means of an adhesive to follow the contour of the edge of the insole but spaced inwardly therefrom, stitching the projection to the inwardly pulled margin of a lasted upper and to the inner margin of a welt, positioning a resilient filler layer in the space bounded by the projection, applying an outsole to the lasted upper-insole-welt unit, and detaching the sole shaped board from the insole and removing it from the interior of the article.
Claim 4
Independent Claim
132 words
A method of manufacturing a welted article of footwear comprising the steps of temporarily attaching a stiff sole-shaped support board to one side of a soft flexible insole formed with an extended marginal portion so that the insole projects laterally beyond the board, securing an elongated flexible projection on the other side of the insole by means of an adhesive to follow the contour of the edge of the insole but spaced inwardly therefrom, stitching the projection to the inwardly pulled margin of a lasted upper and to the inner margin of a welt, positioning a resilient filler layer in the space bounded by the projection, applying an outsole to the lasted upper-insole-welt unit, and detaching the sole shaped board from the insole and removing it from the interior of the article.
Claim 5
Dependent Claim
26 words
A method according to claim 2, wherein the edge of the support board is used as to guide the application of the projection to the insole.
