Device for forming heels on shoes

The invention relates to a device for forming paragraphs on shoes, especially on a machine for attachment of the upper leather on a shoe.

The formation of heels on shoes is known per se Process for which there are numerous machines on the market designed for this purpose. These well-known machines However, they have the disadvantage that they have a low productivity and an operator especially for this operation is required.

The invention is based on the object of the formation of paragraphs on shoes as a separate process and to integrate this process into the shoe manufacturing process.

For this purpose, a device is provided according to the invention, by means of the shaping on a finishing machine continuously with the application process of the upper leather of the paragraph can be made.

An advantage of the device according to the invention is that that the formation of the paragraph takes place directly on the form to be assembled and not on an auxiliary form that is only approximately represents the section of the final shape.

The invention is illustrated below with reference to the drawing, for example explained in more detail. Show it:

Fig.1 schematically shows a side view of a

Assembling machine with a device according to the invention attached to it,

FIG. 2 is a plan view of the device in FIG

Rest position, and

Fig. 3 is a view corresponding to Fig.2 of

Device that is closed during molding.

The device consists of three parts A, B connected to the assembling machine, which are very movable and three-dimensional are adjustable, so that the most favorable position in the work process for different shapes can be taken.

The component A, which performs the formation of the shoulders on the rear part of the mold, is on the rear part of the pusher the Montiermacchine (Fig. 1) assembled while the each other opposite components B laterally on the so-called Plates of the mounting machine are attached. As soon as the upper leather is preassembled on the fitting machine in a known manner the rear pusher moves forward. As soon as the elastic bracket 1 (Fig. 2) with the heel shape comes into contact while the rear pusher continues to press, it deforms and lies down due to the articulation over "the lever 2 so around the shape that he whose outline fits exactly.

Cloicli; '. O: l.tic cylinders 3 and h are set in motion, on the piston rod of which a cushion or molded part 5 or 6 is hinged at the front. The cylinders 3 and 4 press against the corresponding part by means of the cushions 5 and 6

the shape on the side and at the bulge and shape in this way the rest of the paragraph.

The cushions 5 and 6 are shaped and designed so that she . at the end of the operation, the porting of the bracket 1 form in continuous lines, as shown in FIG. 3. Therefore the cylinders 3 and 4 are movable on two vertical axes and can, also automatically, a position in which the cushions 5 and 6 almost touch the ends of the bracket 1.

The cushions 5, 6 and the bracket 1 are made of a suitable elastic material ^{that can be exposed to temperatures of 70 to 80 °} C. without any signs of wear, and has such a hardness that the adaptation to the cut of the shape is favored. It has been shown that silicone rubber has the necessary properties.

The possible automation as regards positioning the cushions 5 and 6 can be carried out in various ways with hydraulic or mechanical means as in the Italian patent application No. 22067 A / 79 dated April 23, 1979 by the same applicant is described.

All of the described movements of components A and B are carried out while the assembling machine is running Duty cycle continues without in any way the The workflow of this machine and thus productivity is impaired.

The heel is formed immediately and without interruption the work cycle of the mounting machine after application of the upper leather on the shape.
