A shoe bottom roughing machine comprises a shoe support (10) and tool supporting means (12) including a tool support member (50) between which and the shoe support relative movement is effected lenghwise, widthwise and heightwise of the bottom of a shoe supported by the shoe support. The tool support member (50) supports a single roughing tool (698) in the form of a rotary radial wire brush and the brush is mounted for swivelling movement about a vertical axis. The machine also comprises dust extraction means including a collecting head (170) connected to a suction source, said head supporting a housing (800) on which is mounted a brush element made up of one or more rows of bristles (810) which surround a region "downstream" of the roughing brush (698), in terms of the direction of rotation thereof, and thus seal said region to form a chamber in which dust and other debris created by the roughing brush can be contained, said chamber being connected through the housing (800) to the collecting chamber (170) and suction source. The brush element (810) also serves to effect a "brushing" action on the shoe bottom during the roughing operation, and thus serves to enhance its cleanliness.

A method for applying glue to an article to a surface (S), which has a layer (L) of a detaching material, includes heating of the surface (S) by a heating plate (20), along a path, which includes substantially the area of the surface (S) to be covered by glue. At the same time, a prefixed pressure is applied to the surface (S) by the same heating plate. The heating and the compression melt the layer (L) of the detaching material together with a surface layer of the body (C ) of the article (F), in order to obtain a mixed layer (LM) having good glue anchoring characteristics. Afterwards, a suitable quantity of glue is applied to the mixed layer (LM) by a nozzle or a holed needle (1, 10).

A combined roughing and cementing machine includes a three position rotary table (12) supporting three shoe clamping (14) assemblies positioned in circumferentially spaced locations for indexing movement around a vertical rotational axis (R) between a loading first position (16), a bottom roughing second position (18), and a bottom cementing third position (20). Roughing and cementing tool heads are stationarily mounted at the respective roughing and cementing locations. This arrangement allows the loading and unloading of the machine to occur independently during the roughing and cementing processes which are on-going at the second and third locations, adding no time to the production cycle.

A roughing machine having a support (68, 72) for supporting bottom-up a shoe assembly (82) formed of a last (84) having an insole (88) located on its bottom and an upper (86) mounted thereon with the margin (90) of the upper (86) secured to the bottom of the insole (88) and roughing tool (74) located above the shoe assembly (82) and yieldably urged downwardly against the shoe assembly (82) so as to rough the upper margin (90) during movement of the support (68, 72) to move the upper margin past the roughing tool (74). The shoe assembly bottom has its heel seat portion (92), its shank portion (94) and its forepart portion (96) lying in different planes. The support (68, 72) is so constructed as to be rockable in such a manner that the heel seat portion, the shank portion, and the forepart portion of the upper margin (90) all lie in horizontal planes during their movement past the roughing tool (74).

An automated system for painting a shoe sole portion of a shoe is provided. The automated painting system is adapted to use a variety of stations and components to automatically paint a side surface of the shoe sole portion while it is secured in a jig, transition the jig to an open position, and remove the painted shoe sole portion from the jig.

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.
摘要:
In the roughing of marginal portions of a shoe bottom using a rotary radial roughing brush (698) the angle of presentation of the operating surface portion of the brush to the shoe bottom marginal portion is such that a longitudinal centre line of the region of contact subtends an acute angle with the perpendicular to the tangent to the shoe edge for each position of the brush in relation to the shoe bottom marginal portion, the region of contact, moreover, lying at the joint-ward side of the perpendicular. This arrangement is especially useful in the inside waist region, especially at the heelward side of the joint region, but is generally applicable both "downstream" and "upstream" of the joint region of the shoe bottom. The acute angle will vary, in particular according to the "spring" of the shoe bottom (i.e. the pitch of the waist region in relation to the forepart region) and is preferably selected by the operator. Where the method is practised in a machine, the machine preferably has a path-determining mode in which the path of the brush along the shoe bottom can be digitised, along three co-ordinate axes and also the angle of swivel of the brush can be determined, as a digitised value, the various digitised values making up a pattern data file for subsequent recall.

A shoe bottom roughing machine comprises a shoe support (10) and tool supporting means (12) including a tool support member (50) between which and the shoe support relative movement is effected lengthwise, widthwise and heightwise of the bottom of a shoe supported by the shoe support. The tool support member (50) supports a single roughing tool (698) in the form of a rotary radial wire brush and the brush is mounted for swivelling movement about a verrtical axis. The various motors (34, 66, 84, 148) for effecting these movements are n.c. motors and a computer control, using programmed instructions, is used for determining the path of the tool along the shoe bottom. For supporting the tool support member (50) for its various movements, a double parallel linkage arrangement (44, 46, 50; 42, 46, 50, 58) is provided which is effective to maintain the tool in its heightwise orientation in relation to the shoe bottom while providing lightness and rigidity for the tool mounting. For effecting rotation of the brush, a single drive belt (122) is provided, driven by a motor (110) which itself is movable to maintain the tension in the belt during widthwise and heightwise movement of the tool support member (50) relative to the shoe support (10).
摘要:
An operating tool, e.g. a rotary radial roughing brush (698), is supported by a tool mounting (692) itself pivotally supported by a tool carrier (682) rotatable about a vertical axis, drive means (680) being provided for effecting such rotation. Height control means (716-724, 740, 742) is also provided, which utilises such rotational movement to vary the heightwise position of the tool mounting (692), and thus of the tool (698) supported thereby, in relation to the tool carrier (682). To this end the drive means includes a rotary spindle and the height control means includes a threaded shaft (716) on which a nut member (740) is carried. The threaded shaft and nut rotate together with the spindle, but the nut can be clamped against rotation; in this way rotation of the shaft (716) together with the spindle is effective to cause heightwise movement of the shaft also to take place.
