Machine for lasting side portions of shoes

The machine comprises a shoe support (10) and two side lasting instrumentalities (20), each of which comprises a fluid bag assembly (40) which, in a tilted position (determined by an abutment 44), is moved into engagement with a shoe, whereafter, by continued inward movement, the bag assemblies (40) are caused to pivot (or roll) upwardly and over the shoe bottom edge, thus to urge the shoe upper around the feather edge of the last and against the insole. The bag assemblies are inflatable, a higher air pressure being applied, so as to apply bedding pressure to the lasting margin, after the assemblies (40) have moved fully inwardly.
