Definitions

  • the present invention relates to a rig for folding the edge of the upper onto a last in a footwear manufacturing machine.
  • machines which provide for the cementing of the edge of the upper to the insole in the area of the forepart of the shoe.
  • Such machines comprise a support on which is positioned a shoemaker's last, to which the insole is applied and onto which the upper is tautened, a series of clasps which grip and stretch the upper, members which secure the last on the support, devices which deposit cement on the insole in the area of the forepart of the shoe, and two articulated plates which provide in said fore-region for the folding of the upper, released by the clasps, onto the insole of the shoe for cementing.
  • the articulated plates have inner edges which interfere with the upper on the last in order to perform the folding.
  • To assist the plates there are provided two opposing lateral pads which are brought against the upper laterally in the middle part of the shoe and which hold the upper pressed against the last in order to aid the folding of the upper by the plates in proximity to this middle region.
  • the reason for this is that the folding of the upper in proximity to this middle region is very critical for the profile which the shoe has in this region and that, especially in certain types of footwear, the rear part is fairly rigid and adversely affects the folding.
  • Document GB-A-1154871 discloses a footwear manufacturing machine comprising a rig for folding the edge of the upper over a last.
  • the folding rig comprises a pair of forepart wipers which are advanced and closed to wipe the upper inwardly over the edge of the forepart of the insole.
  • For lasting the shank portion of the shoe the machine is provided with a pair of lasting units carried on the ends of piston rod extending from fluid operated cylinders.
  • Each lasting unit comprises a resilient band (56) which extends over and between two legs, the band being secured by a clamp.
  • the object of the present invention is to overcome the aforesaid drawbacks.
  • the folding rig illustrated operates in a machine for making footwear of the type indicated in the introduction, that is, one comprising a support on which is positioned a shoe last to which the insole is applied and over which the upper is tautened, a series of clasps which grip and stretch the upper, members which secure the last on the support, and devices which deposit cement on the insole in the area of the forepart of the shoe.
  • the folding rig comprises two plates 10 which articulate around a common centre of rotation and which are actuated by suitable mechanisms, partially visible in the figures, in such a way as to move and rotate, and thus to operate on the forepart of the shoe.
  • each plate 10 has a wedge 11.
  • the folding rig moreover comprises two auxiliary devices 20 arranged on opposite sides with respect to the support on which the last A is positioned.
  • Each device 20 is mounted on a bed 21 of the machine, visible in Fig. 1 only, on which is mounted a pneumatic actuator 22 fitted with an actuating rod 23 operating along a direction X substantially perpendicular to the axis Y of the last A positioned on the support, and in the vicinity of a middle part of the shoe.
  • the rod 23 is integral with a substantially "C"-shaped support 24 mounted perpendicularly to the rod.
  • the bottom arm of the support 24 is fixed to the rod 23, while the top arm of the support 24 carries, elastically, a further arm 25 which extends parallel to the rod 23 towards the last A; in particular, the arm 25 is hinged at 36 in a block 37 at the end of the top arm of the support 24, and a spring 38 mounted on a screw 39 screwed into the block 37 keeps the arm 25 elastically in position.
  • the rod 23 and the arm 25 carry two respective anchoring heads 26 and 27 integrally at their free ends.
  • the ends of a flexible tape 28 are fixed to the heads 26 and 27 in such a way that the tape is tensioned between the said heads.
  • the forward or backward movement of the rod 23 clearly involves an identical movement of the tape 28.
  • a bar 29 parallel to the rod 23 and fitted, in proximity to its other end, with a tooth 30, is fixed to the bottom arm of the "C"-shaped support 24, at one end.
  • an arresting contrivance 31 comprising a pawl 32 intended to interfere with the tooth 30 of the bar 29, actuated by a pneumatic actuator 33 and restored to the rest position by a spring 34.
  • An electronic facility 35 shown diagrammatically in Fig. 1 only, is also envisaged and provides for coordinating the movements of the plates 10, of the auxiliary devices 20 controlling the actuating of the actuators 22 and 33, and of the other members, not illustrated, of the machine.
  • the two tapes 28 are firstly moved forward by the actuators 22, followed by the plates 10, so as to reach, starting from the initial position illustrated in Figs. 1 and 4, an intermediate position illustrated in Figs. 2 and 5.
  • the tapes 28 reach this intermediate position by virtue of the immobilizing of the teeth 30 against the pawls 32. After these operations cement is placed on the insole B.
  • the devices 20 are obviously simple and hence highly reliable.
  • tapes 28 can adapt to lasts of various shape, given their flexibility.
  • the elastic connection of the arms 25 to the "C"-shaped supports 24 makes it possible to compensate for excessive tensions in the tapes 28 during folding.
  • the screws 39 enable the elastic loading of the springs 38 on the arms 25 to be adjusted.
  • the position of the devices 20 on the bed 21 in a direction parallel to the axis Y can be adjusted, by for example connecting the devices to the bed via suitable guides and securing the devices in the preselected position by means of suitable securing members. This adjustment allows adaptation, in addition to that seen earlier, of the devices to lasts of different shapes.
  • the arresting devices 31 turn out to be particularly advantageous for synchronizing the movements of the devices 20 with the movements of the plates 10.
  • the tapes can be replaced with flexible elements which fulfil equivalent functions, supported and propelled in any manner.
  • the tapes can be supported by structures of a layout other than those shown.
  • the structures illustrated turn out however to be particularly simple and effective.
  • actuators may be used, for example hydraulic, electric or other actuators.
  • the tapes can also be elastic and in this case the elastic connection of the arms to the "C"-shaped supports can be dispensed with.
  • the arresting devices can also be omitted in the case in which the electronic facility has suitable sensors to enable it to regulate the movement of the tapes with the movement of the plates.
  • Such securing devices turn out however to be particularly simple and effective.
