DE1138339B - Method and device for covering shoe heels not made of leather - Google Patents

Description

Heels that were not made of leather were previously concealed in such a way that the back of the heel was exactly the same made and stuck appropriate stains.

Due to its thickness, the leather cover could not cling completely to the heel shape, furthermore, the impact on the heel had to be sanded down so that the bulge would not be too strong across from the insole, and finally the leather cutout ran flush with the front edges of the heel, which is why it peeled off when the sole tongue leather was injured. In addition, this was concealment cumbersome, as it had to be carried out individually and very precisely.

A method of overheating a non-leather heel is also known, in which the heel is placed on a support supported by a surface and on top of one by a Radiator heatable plastic film clamped in a frame having a sealing ring which is used to close off an interior space from the outside air. After completing the interior a vacuum is created in it. The frame is not necessarily a paragraph with double-curved surfaces cannot be covered without wrinkles and it must be a proportionate large vacuum can be established.

It is also known, paragraphs with their back facing upwards with a blank, for example made of plastic, closed by hand or mechanically. cover, with overlaps of the cover on the Edge areas of the heel front and on the heel bed can come to rest. This way of working is cumbersome and therefore expensive.

Finally, it is also known to suck in a heated film and thereby create a paragraph with it is placed on a carrier with its running surface pointing upwards, up to the edge of the heel bed area to cover. With such a method, it is not possible to cover the heels without wrinkles.

According to the invention, compared to the method described in the second paragraph, it is proposed that the heels are placed with their backs facing up on brackets carried by a table and then the table against a further sealing ring provided in the interior approximately to to raise the lower front edge of the paragraphs inevitably led to the fixed frame level moves and thereby the interior space essentially on the remaining between the frame plane and the table Space is restricted.

perfectly covered with a plastic film. It is possible, with the appropriate implementation of the Forming machine and size of the film in one operation at the same time a considerable number to be covered by heels. Also the weighty advantage is achieved that a vacuum only in each case a relatively small space is made, whereby the operating costs are significantly reduced will.

According to a further idea of the invention, it is proposed that the plastic film imitates leather Has grain lines as parallel. These parallel grain lines follow in all paragraphs the inventively performed method an arcuate course, so that the impression of a shoe heel made of leather is awakened.

It is known per se, the individual blanks for

To provide the back of the heel with grain lines that imitate leather, but which do not run parallel.

The invention is also used to carry out the method brought a vacuum forming machine in proposal, the paragraph bracket around a horizontal Axis is pivotable and lockable. This has the advantage that paragraphs of the most varied Height and shape can be swiveled into the best possible position for the film. Even there is the possibility, when using foils with parallel, leather-imitating grain lines, the Adjust the bracket so that the grain lines are parallel to the running surface of the heel after covering get lost.

In the drawing is the device by means of which the covering of heels according to the invention is performed, illustrated.

A known vacuum forming machine with an interior 1 has a table 2 that can be raised and lowered with a suction opening (not shown) and two opposite side walls 3 in which mounts 5 for paragraphs 6 are arranged so that they can be rotated and locked about a horizontal axis 4. Each bracket 5 consists of a plate 7 with two vertical stops 8 and 9, one of which (9) is adjustable and provided with a tip 10 so that heels of different heights can be held properly. An opening 11 of the interior 1 is surrounded by a rubber seal 12, on which a plastic film 15 held by a clamping frame 13 with the interposition of a rubber seal 14 rests. On the underside of the edge of the opening 11 there is another seal 16, against which the table 2 is extended.

Three paragraph brackets are illustrated in the drawing. Of course, their number can, depending on which performance is to be achieved can be completely arbitrary.

How the vacuum forming machine works

The plastic film 15 is on its later inside coated with a primer or solvent, so that the contact adhesive to be applied afterwards is better received. The paragraphs 6 are also coated with an adhesive and in the brackets 5 inserted, in such a way that their back points upwards and the lower heel front rests against the vertical stop 8. The second stop 9 with its tip 10 then becomes the system brought to the front part of the paragraph.

If the paragraph 6 is covered with a plastic film that has a grain, so is its holder 5 in such a way to rotate about the axis 4 and determine that the grain is as parallel as possible to the Tread of the paragraph is applied.

The pretreated plastic film 15 is with the coated inside lying down on the Frame 14 stretched, which, together with the film, forms the air seal of the vacuum forming machine. After heating the plastic film to about 100 to 120 ° by a non-illustrated, over The movable or pivotable infrared radiator arranged on the film is the table 2 against the film extended to the inner seal 16, so that this on the one hand, a vacuum space is formed, which is essentially on the between the frame plane and The remaining space on the table is limited, and on the other hand the heels are pressed into the foil with their backs being covered by the foil. The vacuum is then established, whereby the plastic film also wraps around the edges of the heel. Since the work processes only take a few seconds, is to bring about a faster cooling of the film and thus a faster gluing, afterwards then blown cooling air onto the outer surface of the paragraphs.

Finally, the excess parts of the film are cut out at the edges of the heel.

Claims (4)

PATENT CLAIMS: 1. A method for covering shoe heels that are not made of leather, in which the heels are placed on a support supported by a surface and a plastic film that can be heated by a radiator is clamped into a frame with a sealing ring, which is used to close off an interior space from the outside air , and furthermore, after the interior space has been closed, a vacuum is created in it, characterized in that the shoulders (6) are placed with their backs facing upwards on brackets (7, 8, 9) carried by a table (2), the table (2) then inevitably guided against a further sealing ring (16) provided in the interior space (1) until the lower front edge of the shoulders (6) is lifted into the fixed frame plane, and the interior space essentially falls onto the space between the end of the frame and the table (2) ) remaining space is restricted. 2. The method according to claim 1, characterized in that the plastic film with per se known, leather-imitating grain lines is provided as a parallel. 3.
