A system (100) for simultaneously generating a digital bite line and a visible bite line for use in assembling a shoe (110). The system (100) includes: a turntable (160) that receives a shoe sole assembly (114) and rotates at a known rate; a press (130) that applies a predetermined pressure to a lasted shoe upper (112) to engage the lasted shoe upper (112) with a shoe sole assembly (114) retained upon the turntable (160), the press (130) operable to apply the predetermined pressure to the lasted upper (112) while the shoe sole assembly (114) and lasted upper (112) are rotated, and a stylus assembly (150) comprising a marking tip (201) that contacts the shoe upper (112) at a junction line (116) between the lasted shoe upper (112) and the shoe sole assembly (114) and a digital bite line creation unit that communicates measurements of the location of the stylus assembly (150) to a computing device (105) to generate a digital bite line representative of the measurements made of the location of the stylus assembly (150).

There are provided a shoe upper and a method of manufacturing the shoe upper, in which a mesh part is not manufactured separately from the upper when the shoe upper is made, but the mesh part is formed simultaneously with the upper when fabric for the upper is woven, so that an additional operation of sewing or gluing the mesh part on or to the upper is not required. The mesh part may be formed simultaneously with the base part when the shoe upper is manufactured, so that an additional operation of attaching the base part to the mesh part by sewing or adhesion is not required, thus being capable of enhancing productivity, keeping quality consistent, and improving marketability.

A footwear parts processing machine comprises a powered head (11) served by a first carriage (13) supporting a footwear part, a powered head (12) served by a second carriage (14) supporting a footwear part and a powered device (15) for transfer of a footwear part from one of said carriages at an unloading position. Advantageously the two heads (11,12) are side-by-side and the respective carriages (13,14) run along parallel guides (24,25) to each move between a working position (26,27) opposite the respective head and a transfer position (28,29) opposite the transfer device (15) and in its unloading position the transfer device unloads the footwear part in one of said carriages.

Zum Auftragen von Schmelzklebstoffen auf Schuhböden oder Sohlen bei der Schuhherstellung ist ein Klebstoff-Auftragkopf (13) vorgesehen, der einen beheizbaren Grundkörper (28) mit einem mit Klebstoff beaufschlagbaren Kanal (29,42,41,38) aufweist, an dem ein in Betrieb vibrierender Finger (14) gehalten ist. Der Finger (14) dient dem Klebstoffauftrag und weist dazu einen stirnseitig mündenden Kanal (38) auf, durch den der Schmelzklebstoff auf den Schuhboden geführt wird. In Betrieb massiert der Finger (14) den Schmelzklebstoff in die zu beschichtende Lederoberfläche ein. Der erkaltete Schmelzklebstoff ist inaktiv und kann zum Befestigen einer Sohle durch Erwärmen reaktiviert werden.

A carding-cementing machine for shoes comprises a pair of supports (12, 13), each supporting one shoe (14, 15) to be worked. Two working heads (18, 26) are disposed above said supports (12, 13), the first one (18) comprising a carding tool (54) and the second one (26) comprising a cement-delivering tool (56). The supports (12, 13) and the working heads (18, 19) are mutually movable so that the carding tool (54) can travel over a predetermined path on the bottom of a shoe (14) disposed on the first support (12), while the cementing tool (56) can travel over a predetermined path on the bottom of a second shoe (15) disposed on the second support (13). In addition, the mutual positions between the supports (12, 13) and the working heads (18, 26) can be interchanged with each other so as to enable the carding tool (54) to travel over a predetermined path on the bottom of a shoe disposed on the second support (13) while the cementing tool (56) is traveling over a predetermined path on the bottom of another shoe disposed on the first support (12).

The described device is of the comprising a coating head (2) provided with a rotating brush (17) for spreading the adhesive material, in which the coating head comprises a base unit (8), a brush-supporting element (15) slidably engaged to the base unit (8) and spring means (20) acting on the support element (15) and adapted to maintain the brush (17) in a substantially flattened conformation against a component to be cemented.

For controlling the progressive operation of a tool along a predetermined path, wherein at least one operating parameter relating to the operation of the tool can be varied during the progressive operation thereof, a limited number of values for said at least one parameter is pre-set, each value being provided with an identification by which, in a path-determining mode, at each of a plurality of selected points along said path (defined by coordinate axis values for said path) one such value can be selected, the coordinate axis values together with the selected identification being stored for subsequent recall. By way of example, the operating parameter(s) may be the speed of rotation of and/or the pressure applied to a tool of a shoe bottom roughing machine using the speed of rotation of a rotary brush assembly forming part of an adhesive-applying tool assembly and/or the flow rate of adhesive supplied to the adhesive-applying tool in an adhesive-applying machine.

A machine for applying a patch of adhesive onto the bottom of a last (94) comprising an adhesive applying member (89) movable downwardly into engagement with the last bottom and a shifting mechanism (34, 92) operative to so shift the adhesive applying mechanism during its downward movement as to cause the adhesive applying mechanism to engage the last bottom close to the toe end of the last.

A device for removable fastening insoles to corresponding lasts by a strip of adhesive tape, includes means (0) for feeding a tape to a withdrawing station (2), with the adhesive surface of the tape being turned outward. The device includes also means (3) for cutting the tape in the withdrawing station (2). Pliers (2) move vertically from the withdrawing station (2), in which they catch the end of the tape (1), to a lower position, of the adjustable height. A working station (5) is situated beside the path followed by the pliers (2) on the side of the non adhesive surface of the tape. The working station (5) includes a transversal pad (50), moving axially in contrast to the elastic means (56) joined thereto. The working station (5) includes also first sensor means (57a) detecting a predetermined withdrawal of the pad (50) and controlling the cutting means (3) and the pliers means (4), and second sensor means (57b) detecting a predetermined withdrawal of the pad (50), bigger than the previous one, and controlling pushing means co-operating functionally with the pad (50).
