Lederbearbeitungsmaschine mit pneumatischer Walze.
Bei Lederbearbeitungsmaschinen sind als Werkstückunterlagen rotierende pneumatische Walzen bekannt. Sie waren aber meist an Stelle der früher üblichen Vollwalzen mit Gummi-
EMI1.1
durchbiegen konnten. Als Folge davon bekam das zu bearbeitende Leder in der Mitte weniger Druck als an den Seiten. Das machte sich besonders dann bemerkbar, wenn ein starkes Andrücken erforderlich wurde.
Die vorliegende Erfindung beseitigt diesen Mangel dadurch, dass sie die früher übliche Vo) lwalze beibehält und die pneumatische Walze zwischen die Vollwalze und die Ie8serwalze so einschaltet, dass die Vollwalze jetzt als Widerlagerwalze wirkt. Nach der Erfindung sind ferner
EMI1.2
gewissen Grad hinaus oder auch gänzlich zu verhindern. Unter seitlichem Ausweichen ist in diesem Falle das rechtwinkelig zur Druckrichtung erfolgende Nachgeben zu verstehen.
Die Erfindung ist in den Fig. l bis 3 in mehreren Ausführungsformen dargestellt.
In dem Gestell 1 ist die Messerwalze 2 und die Fnrderwalze 3 in bekannter Art gelagert.
Die Walze 3 arbeitet mit einer Walze zusammen, die durch den Schwmgarm 6 in bekannter Weise

Längsnuten versehen, die die Mitnahme der Walze 7 fördern.
Bei gleichem Luftdruck in der pneumatischen Walze erhält man mehr Druck auf das.
Leder, wenn man des Material der Walze 7 durch seitliche Stützen verhindert, seithch auszuweichen d. h. sich auszubauchen. Die festen Leisten A'bremsen die Walze 7 und nutzen sie ab-Man ersetzt sie daher nach vorliegender Erfindung durch Walzen 12 und 1. 3 (Fig. 3).
Damit der Abstand der Walzen. 3 und 7 nicht zu gioss wird. was das Bearbeiten kleiner

Leather processing machine with pneumatic roller.
In leather processing machines, rotating pneumatic rollers are known as workpiece supports. But they were mostly in place of the previously common solid rollers with rubber
EMI1.1
could bend. As a result, the leather to be processed received less pressure in the middle than on the sides. This was particularly noticeable when a strong pressure was required.
The present invention overcomes this deficiency in that it retains the previously common oil roller and connects the pneumatic roller between the solid roller and the liner roller in such a way that the solid roller now acts as an abutment roller. According to the invention are also
EMI1.2
to a certain extent or even to prevent it completely. In this case, sideways deflection is understood to mean the yielding at right angles to the direction of pressure.
The invention is shown in FIGS. 1 to 3 in several embodiments.
In the frame 1, the knife roller 2 and the conveyor roller 3 are mounted in a known manner.
The roller 3 works together with a roller that is driven by the swing arm 6 in a known manner
EMI1.3
Provided longitudinal grooves that promote the entrainment of the roller 7.
With the same air pressure in the pneumatic roller, you get more pressure on the.
Leather, if you prevent the material of the roller 7 by lateral supports, sideways to evade d. H. to bulge out. The fixed strips A 'brake the roller 7 and use it - they are therefore replaced according to the present invention by rollers 12 and 1.3 (FIG. 3).
So that the distance between the rollers. 3 and 7 is not too poured. what editing smaller
