Description

141831 i141831 i

Opfindelsen angår en rammeløs sko, hvis nederste rugjorte skaftrand er ombøjet indefter, og mod hvilken der er formet en sål af plastisk masse.BACKGROUND OF THE INVENTION The present invention relates to a frameless shoe, the lower ridge of which is curved inward, and against which a sole of plastic mass is formed.

Da plastiske masser ikke hefter på pålidelig måde til 5 de glatte flader af skoskafter, er det kendt at gøre skaftet ru på de flader, hvor det kaniner i berøring med sålmaterialet.Since plastic masses do not reliably adhere to the smooth surfaces of shoe shafts, it is known to roughen the shaft on the surfaces where it rabbits come into contact with the sole material.

Denne rugørelse ind til berøringslinien kan først ske, efter at skaftet er blevet trukket på en tilsvarende trælast. Denne arbejdsoperation kraver stor nøjagtighed og er desuden dyr.This stirring into the touch line can only occur after the shaft has been pulled on a corresponding wooden load. This work operation requires great accuracy and is also expensive.

10 Efter den sædvanlige lastning og rugørelse overføres skoskaftet fra trælæsten og til en metallæst til såleformemaskinen. Såle-formens af metal bestående sideramme skal derefter presses fast mod skaftet for at forhindre en udstrømning af plastisk masse under det ved såldannelsen udøvede formetryk.10 After the usual loading and unloading, the shoe shaft is transferred from the wooden shoe and to a metal shaft for the sole forming machine. The metal molded side frame of the sole molding must then be pressed firmly against the shaft to prevent an outflow of plastic mass under the molding pressure exerted during the molding.

15 Det er formålet med den foreliggende opfindelse at tilveje bringe en heftedygtig fladestrimmel til sålmassen ved den neder-ste skaftrand, hvilken heftedygtig fladestrimmel allerede er tilvejebragt før anbringelsen af skaftet på læsten og stramningen af skaftet på denne.SUMMARY OF THE INVENTION It is the object of the present invention to provide a durable flat strip to the sole mass at the lower shaft edge, which durable flat strip is already provided prior to applying the shaft to the shaft and tightening the shaft thereon.

20 Ifølge opfindelsen opnås dette formål ved en rammeløs sko af den indledningsvis nævnte art,ved at skoen ifølge opfindelsen er ejendommelig ved, at skillelinien mellem det glatte synlige skaftområde og både den rugjorte strimmel på den nederste skaftrand samt det formede sålmateriale, hvad angår sin stil-25 ling, er bestemt ved hjælp af en rundgående søm ved den nederste skaftrand i læstekantens område.According to the invention, this object is achieved by a frameless shoe of the kind mentioned above, in that the shoe according to the invention is characterized in that the dividing line between the smooth visible shaft area and both the hatched strip on the lower shaft edge and the shaped sole material as to its style -25 ling, is determined using a circular seam at the lower shank edge of the reading edge area.

Herved opnås det samtidigt, at sålmaterialet ender nøjagtigt dér, hvor skillelinien mellem den rugjorte fladestrinmel og den glatte synlige skaftoverflade forløber, d.v.s. at også tætnin-30 gen af formhulrummet forløber nøjagtigt langs den nævnte skillelinie. Rugøringen af skaftranden til opnåelse af en god heftedygtighed for det sålmateriale, som skal formes, skal ifølge den foreliggende opfindelse ikke først foretages på den på en læst anbragte og strakte sko, men kan ske på forhånd på det syede 35 eller ikke engang syede skaft. Herved opnås der væsentlige fordele, hvad angår omkostninger, arbejdsbesparelse og nøjagtighed.Hereby, it is also achieved that the sole material ends exactly where the dividing line between the hatched surface step flour and the smooth visible shaft surface extends, i.e.. that the sealing of the mold cavity also extends exactly along said dividing line. According to the present invention, the stirring of the shank edge to obtain a good adhesion for the sole material to be formed is not to be carried out first on the loaded and stretched shoe, but may be done in advance on the sewn shaft or not even sewn shaft. This provides significant benefits in terms of cost, labor savings and accuracy.

Det skal her nævnes, at det fra beskrivelsen til engelsk patentskrift nr.744.149 og til USA patent nr. 2789295 er kendt 2 141831 at ombøje skaftranden under læstningen først indefter og derefter udefter. Herunder er en rugøring af skoskaftet imidlertid overhovedet ikke nødvendig, fordi det drejer sig om en rammesko, ved hvilken skorammen dannes af skaftmaterialet, som ombøjes 5 indefter og derefter udefter på den beskrevne måde.It should be mentioned here that from the specification to British Patent Specification No. 744,149 and to U.S. Patent No. 2789295, it is known to bend the shank edge during loading first inward and then outward. However, under this, a stirring of the shoe shaft is not required at all because it is a frame shoe in which the shoe frame is formed by the shaft material which bends 5 inwards and then outwards in the manner described.

Opfindelsen skal herefter forklares nærmere under henvisning til tegningen, der viser udførelseseksempler for opfindelsen, idet fig..1 viser et sidebillede af en skokant, som er anbragt 10 i en form i arbejdsstilling før tilvejebringelse af formetrykket, fig. 2 et til fig. 1 svarende snitbillede, der viser en tilsvarende skokant efter afslutningen af formningen og efter udtagelsen fra formen efter færdiggørelse, 15 og fig. 3 en yderligere udføreIsesform for skokanten ifølge opfindelsen.The invention will then be explained in more detail with reference to the drawing, which shows exemplary embodiments of the invention, Fig. 1 shows a side view of a shoe edge placed 10 in a mold in working position before providing the molding pressure; 2 is a view of FIG. 1 is a similar sectional view showing a corresponding shoe edge after completion of molding and after removal from mold after completion; 15 and FIG. 3 shows a further embodiment of the shoe edge according to the invention.

Ved fremstilling af skotøjet ifølge fig. 1 rugøres en strimmel 2 ved skaftet l's nederste skaftrand indenfor et om-20 råde 3, medens det endnu flade læder løber gennem en i og for sig kendt skær femaskine. Efter denne skærfning af læderet kan der nu dannes en fold 5, som omfatter skillelinien mellem den glatte og den rugjorte del af læderet, og en fremstående kant eller vulst 4. Da syningen af folden først sker efter 25 skærfningen, er det let at sy folden på en sådan måde, at kun en del af vulsten er rugjort, og således at rugøringen ikke strækker sig forbi vulsten og ind på den over folden 5 synlige del af skaftet. Herved sikres det, at pinderanden,d.v.s. den strimmel af skaftet, hvortil sålen hefter, kan gøres ru over 30 det hele.In the manufacture of the footwear according to FIG. 1, a strip 2 is stirred at the lower shaft edge of the shaft 1 within an area 3, while the still flat leather runs through a cutting machine known per se. After this sharpening of the leather, a fold 5 can now be formed, which comprises the dividing line between the smooth and the roughened part of the leather, and a protruding edge or bead 4. Since the sewing of the fold only occurs after the sharpening, it is easy to sew the fold. in such a way that only part of the bead is hatched, and so that the hatching ring does not extend past the bead and into the portion of the shaft visible above the fold 5. This ensures that the stinging duck, i.e. the strip of the shaft to which the sole attaches can be roughened over the whole.

De på denne måde forberedte dele bliver nu lagt på læsten til en skoformemaskine. Den nederste skaftrands strimmel 2 kan midlertidigt holdes i den ønskede stilling ved hjælp af trådklammere eller ved hjælp af snore, indtil sålformens side-35 ramme 11 ligger an. Efter dette anlæg fjernes trådklammeme, eller pindesnorene overskæres, hvis det ønskes, således at læderets spænding trykker vulsten 4 mod sålformens sidekant og tætner. Sålen 8 kan formes af gummi eller andre plastiske masser, 3 141831 hvilket kan ske ved indsprøjtning af massen i det lukkede sålformehulrum eller ved indlægning af råmassen i formhulrummet og tilvejebringelse af formetrykket ved bevægelse af sålestemplet - således som vist i fig. 1. I hvert fald vil trykket i 5 formhulrummet trykke vulsten 4 eller kanten 12 fastere mod formvæggen og tætne fuldstændigt, således at den plastiske masse mellem sålformen og skaftranden ikke kan undvige udefter. Det overskud,som hidtil hyppigt forekom, skulle fjernes ved håndarbejde, hvilket imidlertid for det meste efterlod skammende bear-10 bejdningsspor.The parts prepared in this way are now loaded onto the shoe for a shoe molding machine. The strip of the lower shank 2 can be held temporarily in the desired position by means of wire clamps or by means of cords until the side frame 11 of the sole mold is in contact. After this installation, the wire clips are removed or the cords are cut if desired, so that the tension of the leather presses the bead 4 against the side edge of the sole and seals. The sole 8 may be formed of rubber or other plastic masses, which may be effected by injection of the mass into the closed sole mold cavity or by inserting the raw material into the mold cavity and providing the mold pressure by movement of the sole piston - as shown in FIG. 1. In any case, the pressure in the mold cavity will press the bead 4 or edge 12 more firmly against the mold wall and seal completely so that the plastic mass between the sole mold and the shank rim cannot escape outward. The excess which so far occurred frequently had to be removed by handwork, which, however, mostly left shameful machining traces.

Som det fremgår af fig. 3, kan strimlen 2 af den nederste rand af skaftet 1 først foldes indefter og derefter udefter på en sådan måde, at den fremstående kant 12 af skaftet 1 vender til siden mod sålen 8. Også her vil sålmaterialets tryk presse 15 kanten 12 tætnende mod sålformens sidevæg. Skillelinien mellem skaft og sål udgøres af den indsnævring, som fører til sømmen 16. Da hele den på denne måde dannede vulst 21 er indlejret i sålmaterialet, sikres der en yderligere forbedring af forbindelsen mellem skaft og sål.As shown in FIG. 3, the strip 2 of the lower edge of the shaft 1 can first be folded inwardly and then outwardly in such a way that the protruding edge 12 of the shaft 1 faces sideways toward the sole 8. Again, the pressure of the sole material will press the edge 12 sealingly against the sole of the sole. side wall. The dividing line between shaft and sole is constituted by the constriction which leads to the seam 16. Since the entire bead 21 thus formed is embedded in the sole material, a further improvement of the connection between shaft and sole is ensured.

20 Den fremstående vulst eller strimmel letter ikke alene frem stillingen af skotøjet, men forbedrer også den færdige sko og gør skoens form mere tiltalende. Endvidere forbedres holdbarheden af forbindelsen mellem skaft og sål. Ved færdigørelsen sikrer opfindelsen væsentlige omkostningsbesparelser, da rugørin-25 gen kan foretages før anbringelsen på læst og ved lille arbejdsindsats. En yderligere fordel ved opfindelsen består i, at tætningen af formhulrummet opnås uden kraftige sidetryk mod skaf tet. Hidtil skulle der for at opnå tæthed af siderammens metalkant presses så kraftigt mod skaftlasderet, at formen af skoen 30 eller læderet ofte blev beskadiget.20 The prominent bead or strip not only facilitates the position of the footwear, but also enhances the finished shoe and makes the shape of the shoe more appealing. Furthermore, the durability of the link between shaft and sole is improved. Upon completion, the invention ensures significant cost savings, as the stirring can be done prior to being placed on a read and with little work effort. A further advantage of the invention is that the sealing of the mold cavity is obtained without excessive side pressure against the shaft. Thus far, in order to achieve tightness of the metal edge of the side frame, the shaft weld had to be pressed so strongly that the shape of the shoe 30 or leather was often damaged.

Den plastiske sålmasses tryk benyttes ifølge opfindelsen både til formningen af sålen mod skaftet og samtidig til tætning af formhulrummet.According to the invention, the pressure of the plastic sole mass is used both for forming the sole against the shaft and simultaneously for sealing the mold cavity.

Når der findes en bindsål 9, kan denne eventuelt forsynes 35 med klæbemiddel ved randen og lægges på undersiden af læsten, således at bindsålen forbindes med den nederste skaftrand i kraft af den under anvendelse af tryk og varme tilvejebragte formning af sålen.Where a binder sole 9 is found, it may optionally be provided with adhesive at the rim and laid on the underside of the bead so that the binder sole is joined to the lower shank edge by virtue of the forming of the sole using pressure and heat.
