Abstract
A side (or heel seat and side) lasting machine comprises two lasting rollers (232; 232') arranged one at either side of a shoe support (20) by which a shoe is supported bottom up. Each roller (232; 232') has a helical rib arrangement (294) which, when rotated while in pressing engagement with the shoe bottom, effects an inwiping movement on the lasting marginal portions of the shoe upper. The rollers (232; 232') are inclined to the longitudinal center line of the shoe support, with their free ends directed heelwardly; the acute angle subtended between each center line and the roller axis of rotation is in the order of 50.degree. to 62.degree., preferably 57.degree.. The lasting rollers (232; 232') are of non-metallic material, preferably synthetic polymer or ceramic material, and have a single helical rib the pitch of which is in the range of 10 to 15 mm.
