Description
Durch die deutsche Patentschrift 602 348 ist ein Verfahren beschrieben, das durch in die BaUvulkanisierformen eingelegte Schablonen wohl zunächst Bälle mit vertieften Verzierungen ergibt, dann aber diese Vertiefungen mit abstechender Farbmasse ausfüllt, so daß beim Abtrommeln der Bälle die Farbmasse nur in den Vertiefungen haftenbleibt und glattkugelige Bälle entstehen, deren Oberfläche teils aus Kautschukvulkanisat, teils aus nur aufgetrockneter Farbmasse besteht.The German patent specification 602 348 describes a method that is carried out by in The stencils inserted into the vulcanizing molds were probably initially balls with recessed decorations results, but then fills these depressions with a distinctive color, so that when unrolling the balls, the paint only sticks in the depressions and smooth spherical balls are created, the surface of which is partly made of vulcanized rubber, partly made of only consists of dried paint.
Durch die schweizerische Patentschrift 1057 wird vorgeschlagen, auf einen bereits vulkanisierten Gummiball nachträglich abstechend farbige Verzierungsstücke aus Kautschukmasse, die, in entsprechende Auskehlungen der BaUvulkanisierformen eingelegt, mit Benzin bestrichen werden, durch eine nochmalige Vulkanisation einzuvulkanisieren. Man benutztBy Swiss patent specification 1057 it is suggested to subsequently tap off an already vulcanized rubber ball colored decorative pieces made of rubber compound, which, in corresponding recesses of the Building vulcanizing molds are inserted, smeared with gasoline, by a repeated Vulcanize in vulcanization. One uses
ao also keine Schablonen, sondern für jedes Verzierungsstück eine besondere, entsprechend ausgekehlte Ballform, was sehr teuer wird. Auch die Säuberung solcher ausgekehlter VuI-kanisierformen ist schwierig.So no templates, but for each piece of ornament a special, appropriately grooved ball shape, which is very expensive. The cleaning of such grooved VuI-Kanisierformen is difficult.
Durch die amerikanische Patentschrift ι 551 847 wird vorgeschlagen, mittels eines besonderen Pricklers ein abstechend farbiges Verzierungsstück aus Kautschukmasse auf dem aus zwei Halbkugeln vorgeformten RohbaE zu befestigen und nunmehr das Ganze in glatten BaUformen zu vulkanisieren. Es werden also keine Schablonen benutzt 'und keine Reliefverzierungen erzielt, sondern glattkugelige Bälle. Etwaige Aufdrucke auf den Verzierungsstücken werden beim Abtrommeln der Bälle abgeschliffen oder verwischt.By the American patent ι 551 847 is proposed by means of a special pricklers a striking colored piece of ornament made of rubber compound on the to attach pre-formed raw materials from two hemispheres and now the whole thing in smooth To vulcanize construction forms. So no stencils are used and no relief decorations achieved, but smooth spherical balls. Any imprints on the decorative pieces are abraded or smeared when the balls are unrolled.
Die französische Patentschrift 263 225 beschreibt die Herstellung einfarbiger Bälle mit vertieften Verzierungen mit Hilfe von in die Ballform eingelegten Schablonen, läßt also die nachträgliche Ausfüllung der Vertiefungen mit abstechender Farbmasse fort. Beim Abtrommeln der Bälle schleifen sich die Verzierungen erheblich fort, da die eigentlichen BaUmischungen leicht abschleifbar sein müssen.The French patent specification 263 225 describes the production of single-colored balls with recessed decorations with the help of stencils inserted into the ball shape, so it omits the subsequent filling of the depressions with sticking color mass. When the balls are unrolled, the decorations grind away considerably, since the actual building mixes must be easy to sand off.
Es ergab sich nun die Aufgabe, Kautschukhohlbälle mit abstechend farbigen einvulkanisierten Verzierungen entweder in Hoch- oder in Tiefreliefausprägungen herzustellen, und zwar so, daß nach der Vulkanisation des Balles tunlichst nur der Austriebgrat durch Abschleifen entfernt zu werden braucht, aber das zeitraubende Abtrommeln !und der dabei entstehende Materialverlust erspart wird. Hierfür wurde folgende einfache Lösung gefunden:The task now arose to vulcanize hollow rubber balls with piquant colored ones To produce decorations in either high or low relief, and in such a way that after the vulcanization of the ball, if possible, only the shoot ridge comes through Sanding needs to be removed, but the time-consuming unwinding! And the one with it resulting material loss is saved. The following simple solution was found for this:
In die glatte Ballvulkanisierform wird zunächst leine auf der Hohlseite mit Erhöhungen oder Vertiefungen ausgeprägte, nicht festvulkanisierende glatte Schablone, z. B. ausIn the smooth ball vulcanizing form, a line is first placed on the hollow side with elevations or indentations pronounced, not firmly vulcanizing smooth stencil, e.g. B. off
