Die unterhöhlte, schräg U-förmige Gestalt der Rinnen in der Blechbelagplatte, zu deren Herstellung die neue Vorrichtung dient, ermöglicht, dafs aufgebrachter Putz leicht und vollständig die Rinnen ausfüllt und in ihnen haftet.The hollowed, oblique U-shaped shape of the grooves in the sheet metal plate, to their Manufacture the new device is used, allows that applied plaster easily and completely fills the gutters and sticks in them.
Fig. ι ist ein Schnitt durch eine Platte, bei welcher die schrägen Rinnen neben einander mit entgegengesetzter Neigung so angeordnet sind, dafs zwischen ihnen ein kantiger Steg entsteht.Fig. Ι is a section through a plate in which the inclined grooves next to each other are arranged with opposite inclination so that an angular web between them arises.
Fig. 2 ist ein Schnitt durch die Vorrichtung zur Herstellung dieser Platten, und zwar mit Lage der Theile vor der Herstellung.Fig. 2 is a section through the apparatus for making these panels, with Position of the parts before manufacture.
Fig. 3 zeigt die Lage, welche die Theile bei Fertigstellung der Platte einnehmen.Fig. 3 shows the position which the parts assume upon completion of the plate.
Der zwischen, den beiden schrägen Rinnen α8 α9 der aus dünnem Blech hergestellten Platte A gebildete Steg theilt den Putzbewurf und veranlafst, dafs derselbe in die unterhöhlten Räume geführt wird. Zur Herstellung der Platten werden die Stempelbacken ρ l ρ'2 in dem' auf- und abgehenden Kopf P so angebracht, dafs sie, sobald letzterer die tiefste Stellung erreicht hat, an dem Steg b* des Futters B geöffnet werden, so dafs sie das Blech in die unterschnittenen Räume des Futters drücken. Die Seitentheile bA bl des Futters können zurückziehbar sein, wie aus Fig. 2 ersichtlich, um die Platte abnehmen zu können. Auch kann ein Theil des Futters so angebracht sein, dafs es aufgeklappt werden kann und die Belagplatte auswirft. Die Backen P1P2 werden durch eine zwischen ihren Armen pa angebrachte Feder p5 geschlossen.The web formed between the two inclined grooves α 8 α 9 of the plate A made of thin sheet metal divides the plaster coat and causes it to be led into the hollowed-out spaces. To produce the plates, the punch jaws ρ l ρ ' 2 are attached to the rising and falling head P in such a way that, as soon as the latter has reached the lowest position, they are opened on the web b * of the chuck B so that they do so Press the sheet metal into the undercut spaces of the lining. The side parts b A b l of the lining can be retractable, as can be seen from FIG. 2, in order to be able to remove the plate. A part of the chuck can also be attached in such a way that it can be opened up and ejects the covering plate. The jaws P 1 P 2 are closed by a spring p 5 attached between their arms p a .
Während der Herstellung der Belagplatte werden die Theile ba b* geöffnet, wie aus Fig. 2 ersichtlich, damit die Platte vollkommen in die unterschnittenen Räume gedrückt werden kann, worauf sie wieder geschlossen werden und die Rinnen vollenden. In einigen· Fällen kann das Ende des Stempels voll hergestellt und derart gestaltet sein, dafs es auf den Steg des Futters pafst. Die Seitentheile bs b* sind dabei offen, um das Eintreten des Stempels zu gestatten, und schliefsen sich dann, um die schrägen Seiten der Rinnen zu bilden.During the manufacture of the covering slab, the parts b a b * are opened, as can be seen in FIG. 2, so that the slab can be pressed completely into the undercut spaces, whereupon they are closed again and complete the channels. In some cases the end of the punch can be made solid and shaped to fit the web of the liner. The side parts b s b * are open to allow the punch to enter, and then close to form the sloping sides of the grooves.
