An apparatus for roughing and subsequently applying adhesive to selected portions of a shoe upper, e.g. marginal portions of the bottom of a lasted shoe, has a camera (C) by which the roughed region is scanned and, from such scanning, the extent and also degree of rough are determined and stored as digitised information. From this information firstly the acceptability of the roughing operation is determined, by comparison with a stored model, and secondly the path along which adhesive is to be applied is established so as to ensure that adhesive is applied only to the roughed region.

The apparatus carries out a roughing operation on an edge of an upper (2) mounted on an insole (3) and supported on a movable last (1). The horizontal movements of the roughing brush (56) are determined beginning from a tracer (68) in contact with the edge to be roughed through a potentiometer, an electropneumatic transducer and a cylinder-piston unit, whose movable element operates the brush supporting arm.

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).

The present invention relates to a machine for the roughing of uppers for items of footwear before the operation of injection-molding the sole. The machine comprises overturning means suitable for enclosing said upper (10) fitted on a last (4) of the mold so as to leave unaffected the lower region and the region of the lateral profile to be roughed. A pair of tracer mills (34) is rigidly associated with a movable support which can be moved away from and toward the upper. The mills are rigidly associated with guiding and translation means which move them so as to abrade, in combination, the entire profile of the upper which is left free by the means which enclose it.

A fluffing and carding device for shoe soles comprises a supporting block (1) having incorporated therein a plurality of pneumatically or hydraulically controlled plungers (3), whose rods (4) project from the block (1). The sole (22) is pressed by the plungers (3) against a rigid pressing plane (18). A fluffing and carding unit (20) is disposed at an opening (19) of the pressing plane (18). The supporting block (1) is carried by a carriage (16) adapted to move parallel to the pressing plane (18) so that the whole surface of the sole (22) to be worked comes in contact with the fluffing and carding unit (20).

Machine for performing a progressive roughing operation on shoe bottoms has a three-axis computer controlled stepping motor arrangement (144, 84, 122) for moving two rotary radial roughing tools (168) along a predetermined path in relation to the shoe bottom being operated upon. The tools (168) are also mounted on a common sub-frame (156, 158,160) for pivotal movement about a transverse axis (154) which extends tangential to the shoe bottom engaging portion of the operating surface of the tools, again by computer-controlled stepping motor (232). Grinding stones (630) are provided for grinding the tools (168), and a further stepping motor (186) operates to move the tools (168) relative to the sub-frame (156,158, 160) to maintain the shoe bottom engaging region of the operating surface of each tool in the datum plane in which said transverse axis (154) lies.

A painting system for painting a shoe sole portion of a shoe is disclosed, the painting system comprising: a jig adapted to hold the shoe sole portion in a fixed position when the jig is in a closed position such that only a side surface of the shoe sole portion is exposed; a painting station adapted to paint the exposed side surface of the shoe sole portion while being held by the jig, wherein the painting station is controlled by a computing device having a predefined painting path associated with the jig; and an opening station having an opening mechanism adapted to translate movement of the jig into an opening force that transitions the jig from the closed position to an open position.

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.

A rotary tool machine (10) for processing peltry and footwear items (24) is described, comprising a base (12), at least one motor (18, 18a), and means (48, 50, 54, 56, 58, 60) for transmitting the rotary motion from said at least one motor (18, 18a) to at least one corresponding tool holder shaft (20, 20a), characterised in that it has means (30, 32, 34) for adjusting the height of said at least one tool holder shaft (20, 20a).

An apparatus for shoe manufacture has been conceived which is provided with a shoe-supporting device (3) operatively in engagement with a support frame (2) and with a head block (6) carrying at least one first and one second working tools (7,8) arranged to operate on a shoe (5), as well as actuating means (12) associated with the frame (2) and activated to enable a relative displacement between the shoe-supporting device (3) and the working tools (7,8).

The presence of more than one tool on a single work head allows accomplishment of a machine adapted to perform different working typologies on the shoe (5).

Process for the treatment of shoe soles through ultraviolet radiation combined with ozone. The treatment is applicable to the surface of sole materials which are used in the shoe making industry in order to improve their adhesion properties with various adhesives. The treatment comprises applying low wave length ultraviolet radiation to the sole material by means of an apparatus having a chamber which contains ozone; introducing the sole inside the chamber; controlled removal of ozone, and a system for expelling the treated sole from the chamber.
