Description

KAISERLICHES A IMPERIAL A

PATENTAMT.PATENT OFFICE.

Schlauchförmige Gebilde wurden bisher mittels Walzen, welche bedingen, daß das Gebilde auf beiden Seiten offen ist, oder mittels Platten, welche sogar bedingen, daß die Bahn überhaupt noch nicht geschlossen ist, bedruckt.Tubular structures were previously made by means of rollers, which require that the structure is open on both sides, or by means of plates, which even require that the Bahn is not closed at all, printed.

Mit der nachstehend beschriebenen Maschine sollen fertige Säcke auf beiden Seiten zugleich bedruckt werden. Zur Erreichung dieses ZweckesWith the machine described below, finished bags are to be produced on both sides at the same time can be printed. To achieve this end

ίο sind zwei Druckplatten scherenartig zueinander angeordnet, deren Bewegung wie auch die ihrer Farbwalzen in einfacher Weise durch eine gemeinsame Kurvenscheibe erfolgt, welche so beschaffen ist, daß der eine Teil, wie auch erforderlich, in Ruhe ist, während der andere arbeitet.ίο are two pressure plates like scissors to each other arranged, their movement as well as that of their inking rollers in a simple manner a common cam takes place, which is designed so that the one part, as well required to be at rest while the other is working.

Zwei Druckplatten α drücken von beiden Seiten gegen einen auf ein Brett b gezogenen Sack (Fig. 1). In der auseinandergeklappten Stellung (Fig. 2) werden die Druckplatten von zwei in schwingenden Hebeln c verschiebbar gelagerten Walzen d, welche die Farbe aus zwei mit Polstern versehenen Farbkästen e entnehmen, mit Farbe bestrichen. Druckplatten und Farbwalzen werden durch eine gemeinsame Kurvenscheibe f angetrieben. Die an den Farbwalzen angebrachten Zugfedern g bewirken, daß die Wege der Farbwalzen zwei Sehnen der von den Hebeln c beschriebenen Kreisbogen sind. Die Ablenker h führen die Farbwalzen über die Kanten der Druckplatten und der Farbkästen. Stempel und Hebel sind so ausbalanciert, daß die Rollen sich durch das Übergewicht derselben gegen die Kurvenscheibe legen. Das Brett b kann zwecks leichteren Aufsteckens des Sackes um-'legbar angeordnet werden. Fig. 3 zeigt die Maschine im Grundriß.Two pressure plates α press from both sides against a sack drawn onto a board b (FIG. 1). In the unfolded position (FIG. 2), the printing plates are coated with paint by two rollers d displaceably mounted in oscillating levers c , which take the paint from two paint boxes e provided with upholstery. Printing plates and inking rollers are driven by a common cam disk f . The tension springs g attached to the inking rollers have the effect that the paths of the inking rollers are two chords of the circular arcs described by the levers c. The deflectors h guide the ink rollers over the edges of the printing plates and the ink fountains. The stamp and lever are balanced in such a way that the rollers, due to their overweight, lie against the cam disc. The board b can be arranged so that it can be folded over so that the sack can be slipped on more easily. Fig. 3 shows the machine in plan.
