Description

Verfahren zum Herstellen von Schaftstiefeln aus Kautschuk und Gewebezuschnitten Beim Herstellen von Gummischaftstiefeln zeigt bekanntlich der Schaft das Bestreben. sich auf dem Leisten zusammenzuziehen und dadurch Falten zu bilden. Man hat versucht. dies dadurch zu beheben. daß man mit verschiedenen Vorrichtungen den Schaft. den man über das am fertigen Schuh erwünschte Maß hinaus verlängert während der Vulkanisation straff gespannt hält. ls solche Vorrichtung werden z. B. gummierte Stoffbänder o. dgl. verwandt. die am Schaft befestigt und nach straftem Anziehen des Schaftes kreuzweise über den Leistenschaft gespannt werden.Process for the manufacture of shaft boots from rubber and cut fabric When manufacturing rubber shaft boots, it is known that the shaft shows the tendency. to contract on the groin and thereby form folds. One tried. to fix this. that you can use various devices to cut the shaft. the one extends beyond what is desired in the finished shoe during vulcanization keeps taut. Such a device are e.g. B. rubberized fabric straps o. related. which is attached to the shaft and after tightening the shaft crosswise be stretched over the groin.

Nach der Vulkanisation werden alsdann diese Scbaftbänder und der obere Rand des Schaftes bis aud die gewünschte Schafthöhe abgeschnitten.After vulcanization, these straps and the upper one are then made Edge of the shaft cut off to the desired shaft height.

Dieses Verfahren hat den Nachteil eines immerhin beachtlichen Werkstoffverlustes, eines besonders zeitraubenden Arbeitsganges sowie des schlechteren Aussehens des fertigen Schuhes. da man beim Tragen des Stiefels immer die Schnittfläche des meist hellen Futterstoffes sieht. Hinzu kommt. daß der lose Stoftrand nach einigem Tragen leicht ausfasert und daß das Eindringen von nasser durch die Saugfähigkeit des Futterstoffes an dieser Schnittstelle ermöglicht wird. This method has the disadvantage of a considerable loss of material, a particularly time-consuming process and the poorer appearance of the finished shoe. because when wearing the boot you always use the cut surface of the mostly light colored lining. Come in addition. that the loose edge of the fabric after some wear Fibers easily and that the penetration of wet by the absorbency of the lining material is made possible at this interface.

Bei der Herstellung von ungefütterten Gasschutzstiefeln wird bereits eine Gummierung der ganzen Innenfläche der Stiefel und insbesondere der Schäfte vorgenommen. wodurch das Abgleiten des Schaftes auf dem Leisten mid damit die Faltenbildung verhindert wird. In the production of unlined gas protective boots, a rubber coating of the entire inner surface of the boots and in particular of the shafts performed. whereby the sliding of the shaft on the last and thus the formation of wrinkles is prevented.

Hier ist es also nicht erforderlich, besondere Vorkehrungen gegen die Faltenbildung zu treffen, weil dieser Nachteil hier nicht auftritt. zum Unterschied von gefütterten Schaftstiefeln. wie sie der Erfindung zugrunde liegen.So here it is not necessary to take any special precautions to meet the wrinkling, because this disadvantage does not occur here. the difference of lined shaft boots. as they are based on the invention.

Diese vermeidet nun die besagten Nachteile dadurch. daß ein schmaler, unvulkanisierter Ring aus Kautschukmischung, lösung o. dgl auf die dem Leisten zugekehrte obere Kante des auf die gewünschte Schafthöhe zugeschnittenen Innenfutters vor dem Aufziebeji des Stiefelrohlings über den Leistenschaft auf gebracht wird. Dieser Ring verhindert das Abgleiten des Schaftes auf dem Leisten ohne Anwendung der sonst üblichen Spannbänder. This now avoids the disadvantages mentioned. that a narrow, unvulcanized ring made of rubber mixture, solution or the like on the one facing the last upper edge of the inner lining cut to the desired shaft height in front of the Aufziebeji of the boot blank is brought on over the shoe socket. This Ring prevents the shaft from slipping on the last without using the otherwise usual straps.

Der Schaft selbst wird nicht mehr. wie bisher, über das am fertigen Schuh gewünschte Maß hinaus länger gehalten, sondern gleich auf die gewünschte Höhe zugeschnitten und stramm um den Leisten gelegt. wobei der Ring fest an den Leisten anklebt bzw. durch die dem unvulkanisierten Gummi gegebene Adhäsion anhaftet und das nachträgliche Zusammenziehen des Schaftes und die Faltenbildung verhindert. Der Schutzring vermindert des weiteren die Gefahr des Wassereindringens und gibt dem Schuh ein schöneres Aussehen.The shaft itself is no longer. as before, about the finished Shoe desired size kept longer, but right at the desired height cut and placed tightly around the last. with the ring firmly attached to the ledges sticks or adheres through the adhesion given to the unvulcanized rubber and prevents subsequent contraction of the shaft and the formation of wrinkles. The protective ring also reduces the risk of water penetration and gives the shoe looks nicer.
