Abstract
An apparatus is disclosed for a point lasting machine to fold over an edge of a shaft of a shoe or of a shoe upper at a ball and joint part of a last of the machine. The apparatus includes movable presser members for applying pressure against opposite side surfaces of the last when the shaft or upper is positioned thereon. Associated bands are connected to the presser members respectively for folding over the shaft edge against an underside of an insole of the shoe and for holding the shaft edge in its folded position against the insole. Preferably, the bands are fabricated from an elastic material. Each band extends transversely from its associated presser member for positioning against the respective shaft and shaft edge. A tensioning device is connected to each band for tensioning the band against the associated shaft and shaft edge to fold and hold the shaft edge. Preferably, each presser member includes an elastic member, such as a cushion, disposed at its working end, where the associated band is laid over and extends partially around the cushion.
