Description
Verfahren zum Gummieren von Hanfschläuchen Gummierte Hanfschläuche stellt man so her, daß auf der Innenseite des Schlauches nacheinander eine Anzahl dünner Gummihäutchen (Filme) aufgebracht werden, und zwar geschieht dies -in der Praxis allgemein durch Auftragen gelösten Gummis. Um zu vermeiden, daß beim Aufbringen eines neuen Films der darunter befindliche Schaden @erleidet, wird jeder Film nach seiner Bildung mit durch den Schlauch geblasener Warmluft behandelt und dabei im wesentlichen nur getrocknet. Bei Verwendung von Vulkanisationsbeschleunigern kann dabei aber auch schon ein geringes Anvulkanisieren eintreten. Durch mehrmaliges Behandeln in der beschriebenen Weise wird ein Film auf den anderen geschichtet, bis der Innenschlauch die gewünschte Stärke erhält. Nunmehr erfolgt die Vulkanisation mittels Wasserdampf oder heißer Luft. Es ist in der Literatur auch schon vorgeschlagen worden, in der Schlauchfabrikation Latex zu verwenden, wie dies auch schon bei der Herstellung gummierter Stoffe geschehen ist.Process for gumming hemp hoses Rubberized hemp hoses is produced in such a way that on the inside of the hose one after the other a number thin rubber membranes (films) are applied, and this happens in the Practice generally by applying dissolved gums. To avoid that when applying of a new film @ suffers the damage underneath it, each film is after its formation treated with warm air blown through the hose and thereby im essentially just dried. When using vulcanization accelerators can but also a slight scorching can occur in the process. By repeated Treating in the manner described, one film is layered on top of the other, until the inner tube has the desired strength. Vulcanization now takes place by means of steam or hot air. It has already been suggested in the literature to use latex in hose production, as was the case with the Manufacture of rubberized fabrics is done.
Gemäß der Erfindung wird nun die beidem schichtenweisen Auftragen in der Schlauchherstellung auftretende Schwierigkeit der langsameren Verfestigung der aus Latex gebildeten Schichten dadurch beseitigt, daß jeder neu aufgebrachte Film durch Wärme etwas vulkanisiert wird, so daß also Anvulkanisieren eintritt.According to the invention, the two layers are now applied Difficulty of slower solidification occurring in hose production of the layers formed from latex are eliminated by each new application Film is vulcanized somewhat by heat, so that vulcanization occurs.
Die Filmbildung erfolgt hierbei in der üblichen Art und Weise, indem bei Hanfschläuchen, bei denen die Innenwandungen gummiert werden sollen, die Mischung durch die Schläuche hindurchgeschickt wird.The film is formed in the usual way by in the case of hemp hoses, where the inner walls are to be rubberized, the mixture is sent through the hoses.
