Foreliggande uppfinning avser ett forf aringssatt for framstallning av skobindsulor av grotartade, fiberhaltiga massor. The present invention relates to a method for producing shoe insoles of coarse fibrous masses.

Bindsulor, vilka for anvandning vid skodon maste i sina olika delar uppvisa olika egenskaper, t. ex. olika hallfasthet, bojlighet och tjocklek, hava hittills framstallts genom att enskilda delar klistrats eller pa annat satt fasts pa varandra eller genom pressning i en form. Denna framstallningsmetod uppvisar dock manga nackdelar, &Isom relativt omstandigt arbete, behov av ett flertal olika maskiner och anordningar samt metodens oduglighet for masstillverkning, fransett att pa shdant salt franastallda bindsulor genom ogynnsamt inflytande pa bindemeellet snart falla solider och aven hastigt slitas. Insoles, which for use in footwear must in their different parts have different properties, e.g. different half-strength, flexibility and thickness, have hitherto been produced by gluing individual parts or otherwise attaching to each other or by pressing in a mold. This production method, however, has many disadvantages, & Is relatively cumbersome work, need for a number of different machines and devices as well as the method's inability for mass production, except that on such salt repellent insoles due to adverse influence on the binder soon fall solid and also quickly wear.

Alla dessa nackdelar bortfalla vid framstallningen av bindsulor enligt uppfinningen, vilka _framstallas sasom ett enhetligt sammanhangande helt. Uppfinningen grundar sig darpa, att bincIsulorna framstallas av grotartade fiberhaltiga massor genom gjutning och pressning under sarntidig avvattning av fibergroten i ett ungef Or vertikalt lage av bindsulan, som skall framstallas. Enligt uppfinningen gjutes och pressas bindsulan i sadant lage, att haldelen ligger djupare an den Ovriga delen. Harigenom arias speciellt, att i haldelen, som Jigger lagre, befimaa sig fibrerna tatare, varigenom uppstar storre fasthet, under del att de ovriga delarna uppvisa storre bi5jlighet, vilket alit Or onskvart ifraga om bindsulor. All these disadvantages are eliminated in the production of insoles according to the invention, which are produced as a unitary coherent whole. The invention is based on the fact that the binder insoles are produced from cavity-like fibrous masses by casting and pressing during simultaneous dewatering of the fiber grout in an approximately vertical layer of the binder sole, which is to be produced. According to the invention, the insole is cast and pressed in such a position that the holding part is deeper than the rest of the part. In this way it is especially arias that in the holding part, as Jigger bearings, the fibers are tighter, whereby greater firmness arises, while the other parts show greater flexibility, which alit Or onskvart ask about binders.

Uppfinningen utgar Iran den omstandigheten, att eller igjutning av den grotartade fibermassan i ett karl resp. en form uppstar i dennas nedre del en snabbare avvattning, d. v. s. aven en stone avsattning och fortatning av fibrerna On i den byre delen. The invention gives Iran the circumstance that or casting of the cave-like fibrous mass in a man resp. a mold arises in its lower part a faster dewatering, i.e. also a stone deposition and densification of the fibers On in the upper part.

FOrfaringssattet enligt uppfinningen beskrives i det foljande under hanvisning till bifogade ritning. Fig. 1 visar en enligt uppfinningen framstalld bindsula i planvy. Fig. 2 visar en langdsektion genom bindsulan enligt fig. 1. Fig. 3 visar en tvarsektion genom en maskinell anorcining for utforande av forfaringssatt enligt uppfinningen. The procedure according to the invention is described in the following with reference to the accompanying drawing. Fig. 1 shows a binding sole produced according to the invention in plan view. Fig. 2 shows a longitudinal section through the insole according to Fig. 1. Fig. 3 shows a cross section through a mechanical anorcining for carrying out the pre-set according to the invention.

Framstallningen enligt uppfinningen sker lampligen pa foljande salt: I en behallare 1 pafylles kontinuerligt grotartad pappersmassa 2 till sadan grad, att massans niva alltid intager samma höjd. Samma tjocklek hos blandningen bibehalles genom standig omrdring. I behallarens 1 botten finnes en utloppsoppning, som leder till en cylinder 3, i vilken en kolv 4 Or rorlig. Cylindern 3 Or vridbart anordnad i ett omgivande hus 5 och Or forbunden med ett kugghjul 6, som astadkommer en vridning av cylindern synkront med kolvens rOrelse. Da nu cylindern 3 med sin ifyllningsoppning Or riktad nedat, stanger den utloppsoppningen fran behallaren, och pappersmassan tryckes medelst kolven 4 in i den egentliga presskammaren. Presskammaren Or enligt uppfinningen forsedd med i huvudsak vertikala, perforerade plattor 7, 8, som Aro sa utbildade, att delen av bindsulan med den storsta vaggtjockleken, d. v. s. haldelen, tramstalles i presskammarens undre del. Den ena plattan 7 ar utbildad SaSOM kolv, som vid pressningen ror sig mot den fasta plattan 8. Vattnet lamnar formen forst genom egen tyngd, varpa del utpressas medelst kolven Over hela ytan av del pressade formstycket, tills detta far den onskade formen. Efter bindsulans utpressning nedfalles den framre delen av formen 9 tillsammans med plattan 7, och den firdiga produkten uttages. The preparation according to the invention is suitably carried out on the following salt: In a container 1, continuously grouted pulp 2 is continuously filled to such an extent that the level of the pulp always occupies the same height. The same thickness of the mixture is maintained by constant stirring. At the bottom of the container 1 there is an outlet opening, which leads to a cylinder 3, in which a piston 4 is movable. The cylinder 3 is rotatably arranged in a surrounding housing 5 and is connected to a gear 6, which causes a rotation of the cylinder synchronously with the movement of the piston. When the cylinder 3 with its filling opening Or is directed downwards, it closes the outlet opening from the container, and the pulp is pressed by means of the piston 4 into the actual press chamber. The press chamber Or according to the invention is provided with substantially vertical, perforated plates 7, 8, which Aro said formed, that the part of the insole with the largest rock thickness, i.e. the heel part, is trampled in the lower part of the press chamber. One plate 7 is formed SaSOM piston, which during pressing moves against the fixed plate 8. The water first leaves the mold by its own weight, where part is pressed out by means of the piston over the entire surface of the part molded, until it gets the desired shape. After squeezing out the insole, the front part of the mold 9 falls down together with the plate 7, and the finished product is taken out.

Pressformarna kunna anordnas sa, att flera komma att ligga bredvid varandra och alit efter produktens art, d. v. s. i vissa fall alit efter bindsulans storleksnummer och form, kunna utbytas. The molds can be arranged so that several will lie next to each other and alit according to the nature of the product, i.e. in some cases alit according to the size and shape of the insole, can be exchanged.

Anvandningen av pressformar enligt uppfinningen tillforsakrar exakta dimensioner av den fardiga produkten och mojliggor, att en 2— t23738 — eventuellt anvand gelankforstyvning 10 eller andra inlagg fullstandigt ingjutes i pappersmassan och darigenom icke kunna andra slit lage. Avfasningen 11 yid bindsulans hal bildar lampligen en fortsattning av avsneddningen av den tillhorande listens vagg. Bottenfyllningen 12 ay Hien saint bottenfyllningen 13 av gangdelen bilda dã ett enhetligt heft med den egentliga bindsulan 14. The use of compression molds according to the invention ensures exact dimensions of the finished product and makes it possible for a gelank stiffener 10 or other inserts to be completely embedded in the pulp and thereby not be able to wear other layers. The chamfer 11 yid the sole of the insole suitably forms a continuation of the detachment of the cradle of the associated strip. The bottom filling 12 ay Hien saint the bottom filling 13 of the aisle part then form a uniform booklet with the actual binding sole 14.

Uppfinningen ar naturligtvis ieke begransad till anvandningen ay en pressform, i yilken arbetsstycket framstalles i exakt yertikalt lage, utan efter arbetsstyckets form kan ofta med fordel ett lutande lage ay detsamma anvandas yid pressningen. Framfor alit bOr beaktas, att de delar av arbetsstycket, ph vilka stallas sarskilda ansprak betraffande hallfastheten, under pressningsforloppet komma att ligga lagre an ovriga delar av arbetsstycket. The invention is of course not limited to the use of a mold, in which the workpiece is produced in an exact vertical layer, but according to the shape of the workpiece a sloping layer can often be used in the pressing. Above all, it should be taken into account that the parts of the workpiece, which are made special claims regarding the half-strength, will be lower than other parts of the workpiece during the pressing process.
