Definitions

  • the present invention relates to a process and means for making and using, of footwear bipolar lasts, for shoes and the like, whose polarities are articulated, which are particularly adapted to self extending whereby to stress the shoe or the like being shaped .
  • the present invention relates also the provision of lasts obtained with such process and means and adapted to improve the process for manufacturing shoes and the like, in which they are employed.
  • the lasts for shoes and the like are those tools, difficult to manufacture in itself which, moreover, convey in a process of production, thoroughly determining it.
  • the three realities i) operative arrangement of the last; ii) process and means for its production; iii) process and means for using it.
  • the hinge provided between the two polar bodies, of present lasts for shoes, was relatively cheap, comprising generally one pivot and one spring, shaped substantially as an omega
  • the working of each polar body of each last for shoes, and for its assembling were such and so many to render expensive the arrangement, in its whole, also because, such operations, had to be executed, complying with very strict tolerances and on bodies comprising irregular, heterogeneous and indefinite shapes, particularly unamenable by any mechanical working, in general and in particular to the automatical one.
  • the last instead of determining the shoe shaping process it undergoes it.
  • the invention as claimed is intended to remedy these drawbacks. It solves the problem of harmlessly stressing the shoe or the like being shaped by providing means which are automatizable.
  • the arrangement comprises at least a longitudinal guide, substantially axial, which controls the movement of the shoe last pole members, in a range from 5 mm and 30 mm, keeping them in line and with the same orientation.
  • Such control is provided by a spring which permanently and intensely forces the last pole members to assume a distant position thus shaping the shoe therearound.
  • the guides of the shifting device are at least two and each last pole is provided with an holdable means particularly comprised by a bore.
  • a polygonal cross section or a similar keying therefor is used for maintaining the orientation.
  • a blank body 1, of plastic material, having approximately the shape of a foot and possibly of both feet is provided by moulds 10, 10' (figure 1).
  • the blank body 1 is conventionally placed on a rough shaping machine for lasts of which only the center drill tools 11, 11' (figure 3) and the rough shaping tool 15 (figure 4) are shown.
  • the center drill tools provide the dimples 01, 01' in each end respectively; then the tool 15 provides the rough shaping of last blank body 1" (figure 4).
  • the rough shaped piece is placed on a finishing machine for lasts of which only the centers 14, 14' and the finishing tool 15' are shown.
  • the body 1" is shape finished to provide the semiworked piece 1".
  • the semiworked piece 1Hf is set on an additional finishing machine for lasts of which only the tools 16, 16', 16", are shown, at figure 6.
  • the tool 16 provides the finishing of the forward tapered end by removing the section including the dimple 01; in a second station the tool 16' provides the finishing of the rear end by removing the section including the dimple 01'; according to the present invention in a third station the tool 16" provides the facing of the top side 01" of last which represents an essential reference for the following working setting.
  • the semiworked last 1" of figure 6 is placed on a drilling and capsuling machine of which only a drill 17, a head tool 1T and a wise- chariot 18 for locking and setting the semiworked last, in each of two positions (figure 7 and 8), are shown.
  • a bore is provided by drill 17 (figure 7) and a sleeve 02 is forced therein and in a second stage (figure 8) another bore is drilled and a second sleeve 02' is provided at a calibrated distance from the first one 02 and exactly parallel to same.
  • the semiworked last 1 Hf of figure 8 is set on a special sawing machine of which only a shaft 19, with a pair of disk-like 19', 19' and the wise 18' are shown, in figure 9.
  • the semiworked last duly set and locked, is shown while is being sawn to split the last poles 2, 2' from a short central part 1"", which is discarded.
  • the last forward pole 2 is set on a special horizontal drilling machine of which only the wise 20 and the drill tool 21 are shown.
  • Such forward pole 2' of last is set horizontally locking it with reference to its shape and to the capsule 02 and in this locked condition is bored by the drill 21 to provide the bore 22.
  • the last rear pole Z is set on the special horizontal drilling machine of which only the wise 20' and the stepped drill tool 21' are shown.
  • Such rear pole 2 of the last is set horizontally locking it thereon with reference to its shape and to the capsule 02' and in this locked condition is bored by the stepped drill 21' to provide the stepped bore 22'.
  • the device 333 which controls the shiftable coupling which, according to a preferred embodiment of the present invention comprises: a rod 3, a spring 30, a longitudinal shifting sleeve 33 and a snap ring 03 of coupling.
  • the rod 3 is provided at one end with a cylindrical tang 33" to be coupled with the bore 22", whereby to provide a locked joint therewith.
  • the central part of the rod is polygonal e.g. hexagonal; it is finished as to be shiftable in the sleeve 33.
  • the device 333 is coupled to the poles 2, 2' of the last in assembled condition, i.e. as shown in figures 13, 14 and 15.
  • Such assembling is provided by mounting sequentially on the rod: the snap ring 03, the sleeve 33 and the spring 30.
  • the rear end 33" of device 333 is mounted on the rear pole 2' of the last, by enclosing, between the pole 2' and the ring 03, the spring 30 and the sleeve 33. This is provided by a press of which only the hollow plunger 4 is shown (figure 14).
  • the forward end of device 333 comprised by the sleeve 33, is coupled to the forward pole 2 of the last which is represented by the bore 22.
  • This is provided by a press of which only the plunger 4' is shown (figure 15). Its action is made amenable by the counteraction provided by a rest 4" which is presently removed.
  • a pair of devices 333' are provided, each comprising: a cylindric rod 3', a spring 30', a longitudinally shiftable sleeve 33' and a snap ring 03' of coupling.
  • Each rod 3' is provided at one end with a cylindrical tang' 133" to be coupled with each bore 22" which to any effect is to be considered twice.
  • the central section of each rod is finished so as to be shiftable in each of sleeves 33'.
  • the outer surface of each of sleeves 33' is roughened so as to be lockedly joinable with each of the bores 22.
  • FIG. 19 The way by which the shoe last, according the present invention, can be manipulated by a simple handling device, providing an increased efficiency, in term of stroke and contractibility, i.e., capability of being introduced in and removed from the shoe being shaped, is shown, in a reduced scale, in figures 19 and 20. More particularly, in figure 19 the last 2, 2' is shown in contracted condition and the semifinished shoe 5 is being slipped thereon. Whereas, as shown in figure 20, the last 2, 2' is in an expanded condition and the shoe 5, being shaped thereby, is stressed by one or more springs 30, 30' included in the last to provide a shoe shaping stretching.
  • the device 44 providing the contraction and expanding of the holdable sleeves 02, 02' is very simple and extremely efficient so that even the same process of making shoes results to be improved in that the stretching of members of shoe 5 and in particular its upper occurs in a self governing and permanent way due to the spontaneous action of springs 30, 30'.
