Description

Verfahren zur Herstellung von Gasschutzmasken Die Erfindung betrifft ein Verfahren zur Herstellung von Gasschutzmasken. Bisher -wurden Gasschutzmasken eaitweder aus Feder, Gummi oder Gummistoff hergestellt. Die Gummimasken wurden dabei nicht nur- aus Vollgummi, sondern auch aus mehreren . Gummischichten finit Zwischenlagen aus Faser- und Drahtgewebe hergestellt. Dabei -verfuhr man -auch schon in der Weise, daß man die Schichten aus unvulkanisiertem Gummi und Zwischenlagen aus unzerschnittenem Stoff in der Form preßte und erst nach dem Formen vulkanisierte, so daß der Stoff sich der Form der Verfestigung des Gummis anpassen kannte. Gummistoffmasken, die aus fertigen Gummistoffen bestehen, lassen sich dagegen nicht aus unzerschnittenen Stoffen herstellen. Man ist hier .gezwungen, die Maske aus besonders zugeschnittenen Stücken zusammenzunähen und die Nähte mit Hilfe eines Dichtungsmittels zu dichten oder die Masken an den Nähten zu vulkanisieren.Method for the production of gas protective masks The invention relates to a method for the production of gas protective masks. -Were gas masks so far eaitweder made of spring material, rubber or G ummi. The rubber masks were not only made of solid rubber, but also of several. Rubber layers finite intermediate layers made from fiber and wire mesh. In doing so, one proceeded in such a way that the layers of unvulcanized rubber and intermediate layers of uncut material were pressed into the mold and vulcanized only after molding, so that the material could adapt to the shape of the solidification of the rubber. Rubber masks, which consist of finished rubber materials, on the other hand, cannot be made from uncut materials. Here you are forced to sew the mask together from specially cut pieces and to seal the seams with the help of a sealant or to vulcanize the masks at the seams.

Durch die Erfindung soll die Möglichkeit geschaffen werden, auch Masken aus mehre-, reu Lagen von Textilstoff und Dichtungsmitteln- nach Art der sog. Gummistoffe in Formen ohne Zuschneiden. und Vernähen herzustellen. Die Erfindung besteht darin, daß die Stoffschichten mit dem Binde- und Dichtungsmittel in dünner Schicht belegt und, ähnlich wie bei den bekannten Gummimasken mit Gewebeeinlagen, solange dieses Mittel noch nicht verfestigt ist, in der Form gepreßt werden, worauf das Verfestigen des Bindemittels erfolgt.The invention is intended to create the possibility of also using masks from several, reu layers of textile material and sealants - in the manner of so-called rubber materials in shapes without trimming. and sewing. The invention consists in that the layers of fabric covered with the binding and sealing agent in a thin layer and, similar to the known rubber masks with fabric inserts, as long as this Means is not yet solidified, pressed into the mold, whereupon solidification of the binder takes place.

In der Zeichnung ist ein Ausführungsbeispiel einer nach diesem Verfahren hergestellten Gasschutzmaske dargestellt.In the drawing, one embodiment is one according to this method produced gas mask shown.

Die Maske besteht aus fünf in der Zeichnung mit a bis 5 bezeichneten Raustofffagen. Die fünf Lagen werden lose aufeinandergelegt, dann in eine Form gebracht, verformt und in der Form innig miteinander verbunden. . Dadurch, daß die einzelnen Schichten beim Verformen lose aufeinanderliegen, können sie einzeln nachgeben und die richtige Lage ,einnehmen- Welche Behandlungsart (Z.iB. Erhitzen, Vulkanisieren) zum innigen Verbinden der einzelnen Lagen miteinander angewendet wird, richtet sich nach dem je- weils verwendeten Bindemittel.The mask consists of five layers of rough material labeled a to 5 in the drawing. The five layers are loosely placed on top of one another, then shaped, deformed and intimately connected to one another in the form. . Characterized in that the individual layers on one another during the deformation loose, they can yield individually, and the correct position, einnehmen- Which type of treatment (Z.iB., vulcanization, heat) is used together for intimate connection of the individual layers depends on the in each case binders used.

PATENTANSPRUCH: Verfahren zur Herstellung von Gasschutzmasken aus einer größeren Zahl von Schichten, die ohne besonderen Zuschnitt lose aufeinandergelegt und in einer Form in die gewünschte Maskenform verformt werden, dadurch gekennzeichnet, daß mehrere mit einem zu verfestigmIden Binde- und Dichtungsmittel in dünner Schicht belegte Textilstofflagen in der Form durch eine das Bindemittel verfestigende Behandlung, z. B. durch Erhitzen oder Vulkanisieren, miteinander zu Gummistoff verbunden werden. PATENT CLAIM: Process for the production of gas protective masks from a large number of layers which are loosely placed on top of one another without a special cut and shaped into the desired mask shape in a form, characterized in that several textile fabric layers covered in a thin layer of a binding and sealing agent to be solidified are in the shape by a treatment that solidifies the binder, e.g. B. by heating or vulcanizing, can be bonded together to form rubber.
