Automatic machine to carry out machinings on the edge and bottom of footwear, of the type comprising a plurality of working stations (I,II,III) arranged according to a circular path, along which move the shoes to be machined mounted on lasts (F), one of said stations being used for the operations of loading the shoe to be machined and unloading the finished shoe. In this machine, said circular path extends on a vertical plane.

The invention relates to a rotary preforming machine particularly suitable for the shaping of uppers before the operation of injecting the soles. The machine comprises a stepwise rotary carousel (4) on which a series of openable upper-holder lasts (6) is perimetrally fixed. Each last (6) has a series of holes (10) connected to a water vapor generator by means of tubes. The rotating carousel (4) co­operates with at least two consecutive fixed workstations (12), each comprising a movable carriage (16) guided so as to slide around the upper-holder last (6) which is located thereat by the movement of the carousel (4). Elements (23,24) for beating uppers fitted on the lasts (6) are coupled to the movable carriage (16).

Machine with various operative functions for the processing of shoes comprising:

an oscillating column (11) equipped with centering and supporting members (14, 16) of the shoes (10); a first operating head (2) equipped with rotating abrasive belt (3), suitable for the removal of tufts, precarding and preparation of the shoes (10): a second operating head (22) for pressing and rear rotating carding, comprising surface carding rollers (24) moved by a motor (23) and a lateral shaped felling roller); and a third lateral front oscillating operating head (29) for carding and felling, comprising shaped rollers (31, 31′, 31˝, 31˝′) moved by a movable motor (30); said operating heads and said column being mounted on a same supporting structure (1).
