Vynález sa týká podpátkovej šablony pre vytvoj renie imitácie vrstvených podpátkov nanášaním I laku striekaním. ;BACKGROUND OF THE INVENTION The present invention relates to a heel template for producing an imitation of layered heels by spraying a lacquer. ;

Použitím nových syntetických materiálov í v obuvníckej výrobě dochádza k náhradě klasic- ! i kých prírodných materiálov. Syntetické materiály í . sú svojimi vlastnosťami zvlášť vhodné pre spodko- ? vé diely obuvi. Okrem výborných fyzikálno-me- | i chanických vlastností ich použitie prináša tiež 1 značné sproduktívnenie výroby obuvi. Obuv z prírodných materiálov je však medzi spotrebitelmi oblůbená a čoraz viac vyhladávaná nielen pre svoje úžitkové vlastnosti, ale aj pre charakteristický povrch a jej výroba nestačí na uspokojenie ich záujmu. S cielom čo najviac sa přiblížit’ charakteristickej kresbe prírodnej usne sa syntetické materiá- ly povrchovo upravujú róznym spósobom. Jedným z nich je tiež vytvorenie imitácie zbíjaného podpát- ' ku z viacerých vrstiev spodkovej usne na podpatku monolitnej podošvy alebo iba na samotnom podpatku, ktorý sa potom k podošve připevňuje. Najproduktívnejším spósobom vytvorenia takejto imitácie je nanášanie laku striekaním. Z doteraz používaných zariadení pre získanie uvedeného efektu sú najrozšírenejšie striekacie zariadenia majúce medzi ústím striekacej pištole a podpátkom umiestnenú rovinnú šablonu, a to buď vo formě monolitného dielu, alebo vytvorenú z ocelových, nylonových alebo iných vlákien. Tieto šablony sú ešte opatřené stierkami rozličnej kon- I štrukcie na odstránenie laku, nastriekaného na ich povrchu. Lak potom stéká do zbernej nádoby, umiestnenej pod šablonou. Nevýhodou je kompli- : kované a nekvalitně čistenie šablony. Pre odstránenie tohoto sa používajú tiež striekacie zariadenia, využívajúce vzduchovú clonu. V tomto případe je medzi striekacou pištolou a podpátkom umiestnená viacdielna tryska. Prúd vzduchu z tejto trysky lúčovite přetíná prúd striekaného laku a strhává ho na zbernú stenu, odkial’ stéká do zbernej nádoby. Tým sa na lakovanom podpatku vytvoria nena- ! striekané pásiky. Používá sa ďalej konštrukcia, kde ; i ocelové vlákna, zamedzujúce přístupu striekaného i laku na určité časti podpatku, majú kruhový tvar. I V spodnej časti zasahujú do nádoby s rozpúšťad- lom a otáčaním sa čistia od nastriekaného laku. Zariadenie sa dá využiť obtiažne pri úpravě pod( patku monolitnej podošvy. 1 í ( Tieto konštrukcie, aj keď sú univerzálně použitelné, majú však spoločnú nevýhodu, ktorou je ! j nedostatočná kvalita takto upravovaného povrchů, i Konštrukcia zariadenia a tvar podpatku totiž nedo- I volujú umiestnenie šablon ani vzduchovéj trysky j v bezprostrednej blízkosti povrchu podpatku, čím dochádza vplyvom rozptylu čiastočiek laku tiež k nastriekaniu tých častí podpatku, ktoré majú : zostať čisté. Okraje vytváraných pásikov sú nekontrastné, nie jé medzi nimi ostrý přechod.The use of new synthetic materials in the footwear production leads to the substitution of classic! natural materials. Synthetic Materials. are particularly suited for underwear? parts of footwear. In addition to excellent physico-me | In addition to the chemical properties, their use also brings about a considerable production of footwear. However, footwear made from natural materials is popular among consumers and is increasingly searched not only for its utility properties, but also for its characteristic surface and its production is not enough to satisfy their interest. In order to get as close as possible to the characteristic drawing of natural leather, the synthetic materials are surface treated in a different way. One of them is also to create an imitation of a punched heel from a plurality of underside leather heels on a monolithic sole or only on the heel itself, which is then attached to the sole. The most productive way to create such an imitation is by spraying paint. From the hitherto used devices for obtaining the aforementioned effect, the most common spraying devices having between the spray gun mouth and the heel are a planar pattern, either in the form of a monolithic part or made of steel, nylon or other fibers. These templates are still provided with a variety of constructions to remove paint sprayed on their surface. The lacquer then flows into the collection container located below the template. The disadvantage is the complicated forged and poor quality cleaning of the template. Sprayers using an air curtain are also used to remove this. In this case, a multi-part nozzle is disposed between the spray gun and the heel. The jet of air from this nozzle jets the jet of spray paint over it and entrains it onto the collecting wall from where it flows into the collecting container. This will not be created on the painted heel. sprayed strips. Furthermore, construction is used where; even steel fibers preventing spray and lacquer access to certain heel parts are circular in shape. I At the bottom, they reach into the solvent container and rotate to remove the spray paint. The device is difficult to use under (under the sole of the monolithic sole (Although these structures, although universally applicable, they have the common disadvantage that the quality of the surfaces so treated is insufficient, because they choose to position the stencils or the air nozzle in the immediate vicinity of the heel surface, thereby also causing the parts of the heel to be sprayed to remain clean as a result of the scattering of the lacquer particles. The edges of the strips formed are non-contrasting, not a sharp transition between them.

Claims

SUBJECT 1. The heel template for creating an imitation of sliced heels by spraying the spray219697

These drawbacks are overcome by a template according to the invention, characterized in that a sheath consisting of an equidistant surface is attached to the support surface and provided with parallel grooves. The support surface has a centering recess in the heel portion.

The technical effect of the invention is manifested in particular in achieving the maximum contrast of the strips formed. . .

An exemplary embodiment of a template according to the invention is shown in the accompanying drawings, wherein FIG. 1 shows a perspective view of a template with a monolithic sole fastened and a part of the spraying device, FIG. 2 is a front view of the template; and FIG. 3 top view template.

The template 1 _t made of sheet steel is supported by the clamping pin 13 on the clamping pin 2 and secured against rotation by the pin 14. The pin 14 is pressed in the clamping pin 13 and this is in turn pressed into the support flat 12 of the template 1. a bracket 3 attached to a clamping mandrel 2 rotatable about its own axis. The template 1 has, in the heel part, a shell 11 attached to the support 12, which has the shape of the treated heel enlarged by 0.5-2 mm. Thus, the shell 11 is an equidistant surface to the surface of the heel. In contrast to the clamping mandrel 2, a vertically arranged pressure mandrel 4 presses the workpiece to the template 1. In addition, a centering recess is formed in the support flat 12 of the template 1. The sheath 11 of the template 1 is provided with parallel grooves d, the number and width of which are chosen according to the number and depth of the reeds to be imitated on the heel. The grooves d are on their own. machined arranged horizontally. Compared housing ¹ 11 is positioned striekaciapištol '5. machined monolithic sole 6 is deposited on a support surface 12 template 1. heel soles while 6 are inserted into the centering recess in the support surface 12 by the action footswitch, controlling the pneumatic cylinder, not shown in the figures, the the pressure mandrel 4 slides vertically down and presses the heel of the sole 6 to the support flat 12 of the template 1 and the sole 6 is thus reliably fastened. The clamping mandrel 2 is rotated by 180 ° together with the clamping sole 6 during spraying of the paint from the spray gun 5, thereby forming strips having the shape of parallel grooves d formed in the sheath 11 of the template 1 over the entire heel. with clamped outsole 6 returns to the starting position, the pressure mandrel 4 extends vertically upwards, the sole 6 is released and allows the template 1 to be removed and inserted further for machining. If desired, the soiled spray paint template 1 is removed from the clamping mandrel 2 and replaced with a clean one and cleaned by immersion in a suitable solvent to prepare it for further use.
