Abstract

Aspects hereof relate to an apparatus and method for coupling a cemented upper to a sole of an article of footwear. Pairs of clamps secure a sole at a forefoot region and a heel region to prevent movement of a location of the sole upon application of a perimeter deforming force. Perimeter deforming implements apply such force to a bottom surface of the secured sole causing the perimeter of the top surface of the sole to splay open outwardly from the longitudinal axis of the sole. While the top surface of the perimeter is splayed, a cemented upper is caused to contact the top surface of the sole in a longitudinal direction from the heel end to the toe end. Once in place, the force on the bottom surface of the secured sole and the clamps is released leaving the top surface of the sole properly adhered to the upper.

First claim

What is claimed is:

1. A manufacturing apparatus for an article of footwear, comprising:
first and second pairs of clamps that secure in place a sole of the article of footwear, the first pair of clamps cooperating to secure a ball region of the sole and the second pair of clamps cooperating to secure a heel region of the sole; and
first and second perimeter deforming implements that, when initiated, apply pressure to a bottom surface of the secured sole causing a lateral rim and a medial rim of a perimeter of a top surface of the secured sole to open outwardly from a central longitudinal axis of the sole.

2. The manufacturing apparatus of claim 1 , wherein the first pair of clamps includes a medial clamp positioned at the ball region of a medial edge of the sole and a lateral clamp positioned at the ball region of a lateral edge of the sole.

3. The manufacturing apparatus of claim 2 , wherein the second pair of clamps includes a medial clamp positioned at the heel region of the medial edge of the sole and a lateral clamp positioned at the heel region of the lateral edge of the sole.

4. The manufacturing apparatus of claim 1 , wherein the first perimeter deforming implement is positioned within the ball region of the sole, and wherein the second perimeter deforming implement is positioned within the heel region of the sole.

5. The manufacturing apparatus of claim 4 , wherein the first perimeter deforming implement and the second perimeter deforming implement are positioned at or near the central longitudinal axis of the apparatus.

6. The manufacturing apparatus of claim 1 , wherein when the first and second perimeter deforming implements are initiated, the pressure applied to the bottom surface of the secured sole causes a convex curvature of the bottom surface of the secured sole surrounding each of the first and second perimeter deforming implements.

7. The manufacturing apparatus of claim 1 , further comprising a reducing element secured to a top surface of each of the first and second perimeter deforming implements, the reducing element having a smaller top surface area than a surface area of the top surface of the first and second perimeter deforming implements.

8. The manufacturing apparatus of claim 1 , further comprising a toe securing element that secures in place a toe end of the sole.

9. The manufacturing apparatus of claim 1 , wherein at least one of the first pair of clamps and the second pair of clamps is movable in one or both of a lateral direction and a longitudinal direction to accommodate a plurality of articles of footwear of varying sizes.
