Method and gluing press for gluing shoe soles with upper shoes

The invention relates to a method for gluing shoe soles with upper shoes, in particular for gluing soles in Louis XV shoes and so-called. Shell soles, in which a raised sole edge must be glued to the upper of the upper shoe.

After. German Patent 1,212,445, a mold for Louis XV shoes is already known, in which the sole is to be pressed against the upper and the heel by means of elastic pads. A uniform contact pressure cannot be achieved with this mold despite a very complex mechanism provided for sealing the contact pressure. In particular, simultaneous pressing of the sole to the "Yordercnuh" and to the heel does not appear to be possible. This mold is neither intended nor for gluing peel soles suitable.

It is already known to a great extent that for even distribution of nasty contact pressures3 when the soles are pressed into place on ordinary shoes, leather cushions filled with a pressure medium are added

but could use hit this druoknittel-filled pillow only a contact pressure perpendicular to the running surface of the sole is exerted. For pressing the soles of louis SCV shoes or from shell soles, these essentially flat cushions were not suitable.

The invention is based on the object of a method to find fe, by means of which when gluing soles with upper shoes, also with Louis-ZV shoes and shell soles, regardless of the respective sizes and the respective shape, without a special setting being made must, on all bar areas of the adhesive seam that are directed in the same way an evenly distributed contact pressure is exerted perpendicular to the glue seam and thus on simple white glue presses are in one work step is made possible »

. . In a method for gluing shoe soles with ™ upper shoes by means of a gluing press, the pressure being applied by a pressure medium located in a pressure space closed off in the direction of the shoe sole by a flexible membrane is, the solution according to the invention is <° that one compared to its unloaded state many times over Their dimensions expandable membrane by introducing pressure medium into the pressure space, around the sole and the adjacent sole Sections of the overshoe, if necessary, the entire upper

^ brought to the support without creases and finally by pressing the pressure medium is pressed against the sole and the upper or its sections with pressure.

According to an embodiment of the method according to the invention the membrane is prepared by closing the adhesive press on the sole or on sections of the sole, whereby a Fixation of the sole with respect to the upper shoe is achieved, the sole thus at a change in its position with respect to the Upper shoe is prevented.

Mach of the invention becomes one for practicing the method Glue press with one in the direction of the shoe sole proposed a pressure chamber closed off by a Menbran, in which the Meabran has an extensibility by a multiple of its expansion in the unloaded state, the upper wall the bridge bounded on its underside by the membrane, Raumes as a fixed hood, bell or the like. is formed, to the calibration approximately the same edge from below a bowl with a Device for receiving the overshoe pulled onto a last and the one with the insertion of an adhesive on these attached shoe sole, and on the means for closing and applying the hood to the shell during the Fretting and for removing the hood from the shell for removing and inserting a shoe are provided.

overshoe bait.

Furthermore, according to an embodiment of the invention, it is proposed that the device for ^A ufnähme dee Oberachuhes beeteiht from an opening provided with a sealing bead, at the bottom of the shell "or in the lower part of the hollow body, which is not only a less expensive solution in the manufacture of the gluing press _f but also a simple and secure insertion of the upper shoe is made possible, while the Diohtungewul ^ prevents a passage of the pressurized and stretched membrane or rubber bladder.

Finally, according to one of the above-described alternative embodiments of the invention as a device for The shoe is placed on the bottom of the shell or lower part of the hollow body a pin or the like. zub attaching the last arranged »whereby this solution is particularly in the production Louis XV shoes or other shoes more difficult Shaping is suitable.

In the drawing, the essence of the invention is illustrated; show it:

o Fig. 1 shows a glue press, set up for glue press

of Louis XV shoes, in cut;

Fig. 2 the glue press, set up for glue presses ° of so-called. Shell soles, in section} and

S ¹ Ig. 3 a glue press in which the membrane consists of a rubber bladder, generally a section.

According to Fig. 1 and 2, a glue press for the exercise of the Procedure initially from guide pillars 1, one on these slidably mounted, fixed Raube 2 and a shell 3 or 3 * attached to the guide columns 1. the Hood 2 is on its open side facing the shell 3 or 3 'by means of a frame 4 and Screws 5 held membrane 6 closed, so dad the inner wall of the hood 2 and the membrane 6 one by one the hood 2 provided connection piece 7 with pressure medium represent pressurizable pressure chamber 8 · The membrane 6 has an expandability by a multiple of its expansion in unloaded state. The meeting edge 9 of the hood 2 and edge 10 or 10 'of the shell 3 or .. 3 * are aligned with each other. A holder 11 is also seen on the hood 2, into which one element 12 engages, the other of which End in a manner not shown with an actuating device, for example with a pressure medium cylinder double pressurized pressure medium piston, for closing and opening the glue press is connected.

After Pig. 1 is a device inside the shell 3

Ct 13 for receiving an upper shoe 15 drawn onto a last 14 - here a Louis XV shoe - and one below

^m insertion of an adhesive on this applied shoe sole, provided. Finally, there are 3 entrances and entrances at the bottom of the sohale

Vent openings 17 arranged

Räch Fig. 2 is the shell 3 'with one as an exchange Barer use auegebilden device 18 provided, the one having a through-hole 20 padded with a sealing bead 19. In the breakthrough 20 from above, a strip 14 * 15 * sucked overshoe inserted, on the under insertion a shell sole 21 is placed on top of an adhesive.

Räch Fig. 3, a glue press for performing the method of one of FUhrungesäulen 1 "slidably mounted upper part 22 and a to the FUhrungesäulen 1 ⁿ fixed lower part 23 of a hollow body 22,23 'and, arranged in the upper part 22 of the rubber bladder 24, the interior of a DruckrauB 25. In the lower part 23 of the hollow body 22, 23 designed as an exchangeable insert device 18 ″ is provided, which shows an opening 20 ″ padded with a sealing bead 19 ″, into which an upper shoe pulled onto a strip 14 ″ from above 15 "is used, on which a shell sole 21" is applied with the insertion of an adhesive. On the upper part 22 there are a connecting piece 7 "^ ₃ for the pressure medium and a holder 11" _t in which an element 12 "is used to open and close the Glue press engages.

Then the following mode of action results:

After Pig. 1 is when the hood 2 is lifted off the shell 3,

wherein the pressure chamber 8 is not pressurized and the The membrane 6 is not subject to any stretching, that is to say it shows an approximately level position, the strips 14 with the open Upper shoe T5, a Louis XV shoe, on the under * insertion of a Adhesive a shoe sole 16 is placed on the device 13. Now the hood 2 is placed on the shell 3, whereby the membrane 6 rests on the shoe sole 16 and the heel due to its elasticity and thus a

w pushing the shoe sole 16 is prevented. While the Hood 2 and the shell 3 are kept closed, the pressure chamber 8 is acted upon with pressure medium in such a way that the membrane 6 expands and follows all of its contours to the shoe sole 16 and the upper 13 as well as the the paragraph located thereon without creases. The air located between the membrane 6 and the shell escapes in the process through the 3nt or ventilation openings 17 · Thereupon the pressure medium located in the pressure chamber 8 is pressurized

^ which is now perpendicular to all glued seams that are aligned in the same way directed and comes into effect in all areas with the same contact pressure. This makes it possible for everyone Zones of the adhesive seam, whether on the front shoe or on the bridge

to or at the front of the paragraph, in one go

to glue and to press. Changes in size or shape

^ ° do not require any new setup or adjustment of the . Gluing press »

An alternative procedure is in Pig. 1 illustrated by the membrane 6 shown partially in dash-dot line, Here, the membrane 6 is only so far against the shoe sole 16 and sections of the overshoe 15 * in particular the heel laid out as required for uniform application of the areas exhibiting adhesive seams. Such a limited one The expansion of the membrane 6 enables the membrane to be bonded to be pressed against one another in a completely sufficient manner while protecting it Parts.

After the contact pressure has taken effect in the required amount and time, the pressure chamber 8 is relieved of pressure, if necessary, if this is not already done by the restoring force exerted by the membrane 6, pressure medium is withdrawn from the Druclcrauia -8 and the hood 2 from the Shell 3 lifted off ₉ whereupon the shoe, which is firmly and evenly glued to the shoe sole 16 and is finished with the last 14, is removed. ^

After Pig. 2 corresponds to the procedure and effect essentially the one described above, but here is the

Upper shoe 15 * drawn on the last 14 'with the peeled sole 21 attached with the insertion of an adhesive inserted or placed in the Durohj £ fraction 20 of the insert 18 of the shell 3 *.

The sealing bead 19 not only makes damage to the overshoe 15 * impossible, but also in particular a passage through the membrane 6 b $ i its impact with pressure medium and pressure through gaps between the upper shoe 15 * and the insert 18 prevented. As the Can be seen in the drawing, the membrane 6 comes to support at a relatively low stretch the sealing bead and only a small volume of pressure medium is required to attach the membrane 6 to the shoe sole, in particular the shell sole 21 and the sections of the upper 15 * adjacent to it, free of folds In this way, the time required to apply the membrane 6 can be reduced in a simpler manner Shaped shoes can be kept small without reducing the quality of the adhesive pressing. Rather, it is sufficient here a membrane 6 made of a not so extensible and possibly cheaper material. Second, it is subject to the membrane 6 with only a small amount of required elongation, less fatigue, and its service life becomes conceivable extended.

In Pig. 2 is particularly illustrated how by means of

J _{0 of} the method according to the invention shell soles 21 at the same time

££ Operation and with even pressure on a very simple one Way to be connected.

After Pig. 3, the process and the mode of action essentially correspond to those of Pig. 2, but there is no membrane here clamped on the upper part 22, but a rubber blade 24 or the like arranged in the upper part 22. This rubber bladder 24 when pressurized with pressure medium and with pressure is supported on the upper part 22 and lower part 23 of the hollow body 22, 23 *, so that the contact pressure is essential to the effect on the shoe

sole or shell sole 21 "and the adjacent sections of the Upper shoe 15 "gets, which of course also analogously would apply to a Louie XV shoe. This arrangement has the particular advantage that the rubber bladder 24 very quickly and particularly in the event of damage or otherwise becoming unusable can be exchanged easily.

It is advantageous if the media · to close, pressing and removing the cover 2 with respect to the shell 3 or 3 ¹ and the upper part 22 relative to the lower part 23 consists of the hollow body 22,23 made of a pressure-medium cylinder with double is pressurized pressure medium piston and with the Pressure medium system to act on the pressure chamber 8 or 8 "is connected.
