Abstract
A single-station combined toe and side lasting machine comprises pulling over instrumentalities 20, 22 for tensioning an upper over its last, toe lasting instrumentalities, including toe wipers 38, toe pad 48 and toe band 50, a heel support 56, two adhesive applying nozzles 28 and side lasting instrumentalities 114 constituted by two lasting rollers 176. In operation, with the upper tensioned, first the shoe is clamped by the toe lasting instrumentalities and heel support to allow adhesive to be applied progressively along opposite side portions from the toe to heel breast. Then the lasting rollers operate progressively from the ball region to the heel breast, and, when the rollers have cleared the ball region, the inwiping movement of the toe wipers is completed. The nozzles and side lasting rollers are mounted on a common carriage 26 which moved rectilinearly, supports 116 for the rollers being mounted for movement thereon about three perpendicular axes 82, 122, 140. The rollers are also supported by carriers 174 on said supports for pivotal movement about a further axis 170. In this way, the rollers can follow the contour of the shoe bottom and also the angular relationship of t…
