Pappenschere. Patentiert im Deutschen Reiche vom 5. Juni 1913 ab.Cardboard scissors. Patented in the German Empire on June 5, 1913.

An Pappenscheren bekannter Bauart, bei denen der Anlegetisch zusammen mit dem Untermesserbett aus einem Stück gegossen ist, wird vielfach die den Messern entgegenliegende Seite des Tisches verstärkt und als Führung für die verschiebbare und feststellbare Querleiste ausgebildet. Solche Maschinen jedoch, bei denen das Untermesserbett nur schmal ist und der Anlegetisch in einerOn cardboard scissors of a well-known design, in which the feed table together with the If the lower knife bed is cast in one piece, it is often the one opposite to the knives Side of the table reinforced and used as a guide for the movable and lockable Cross bar formed. Such machines, however, in which the lower knife bed only is narrow and the feed table in one

ίο Platte aus Holz, Blech oder ähnlichen Stoffen besteht, in zweckmäßiger Weise mit einer Führung für die verschiebbare Querleiste auszurüsten, war bisher nicht bekannt. Man hätte eine besondere Führungsleiste an der freien Längsseite des Tisches anbringen müssen, sah aber davon ab, weil dies aus Rücksicht auf das Verziehen und Schwinden der Holzplatte und das Werfen des meist recht' leichten Blechtisches keinesfalls eine sichere, genaue Führung für die Querleiste ergeben hätte. Es wurden daher Pappenscheren mit einer Tischplatte aus Holz oder Blech mit verschiebbarem Querwinkel nicht ausgeführt. Gegenstand der Erfindung ist eine mit jginem Anlegetisch aus Holz, Blech oder ähnlichen Stoffen versehene Pappenschere, die mittels einer den Tisch überbrückenden und auf dem Untermesserbett kräftig gestützten Führung die verschiebbare Querleiste feststellbar sicher leitet. Da diese Führung nicht in unmittelbarer Verbindung mit dem Veränderungen unterworfenen Tische steht, bleibt stets eine genaue sichere Stellung der Querleiste zu den Messern gewährleistet.ίο Plate made of wood, sheet metal or similar materials consists of equipping in an appropriate manner with a guide for the sliding crossbar, was previously unknown. A special guide rail would have to be attached to the free long side of the table have to, but refrained from doing so because this out of consideration for warping and shrinking the wooden plate and the throwing of the mostly very light sheet metal table by no means one safe, accurate guidance for the crossbar would have resulted. There were therefore cardboard scissors not designed with a table top made of wood or sheet metal with a movable transverse angle. The subject of the invention is one with jginem feed table made of wood, sheet metal or Cardboard scissors provided with similar materials, which by means of a and The sliding cross bar can be locked on the guide, which is strongly supported on the lower knife bed safely directs. Because this leadership is not directly related to the changes subordinate tables, there is always an exact, secure position of the crossbar guaranteed to the knives.

Die Zeichnung stellt eine Ausführungsform des Erfindungsgegenstandes dar, und zwar zeigt:The drawing represents an embodiment of the subject matter of the invention, namely shows:

Die Führungsstange α ist in zwei seitlich an dem Untermesserbett b befestigten Stützen c und d gelagert und wird umschlossen von einem Leitstück e, an welchem die verschiebbare Querleiste f starr befestigt ist. Die Führungsstange α liegt einerseits parallel zur Schneideebene der Messer g und h und andererseits parallel zu der Anlegeebene der Tischplatte i. Die Führungsstange wird zweckmäßig möglichst nahe am Niederhaltebalken k angeordnet, um das Anlegen der Werkstücke nicht zu hindern. Das Leitstück e kann auf der Stange α in entriegeltem Zustande mit der Querleiste b in der Längsrichtung der Messer verschoben und an jeder beliebigen Stelle der Stange festgestellt werden. Um die Querleiste f einerseits leicht auf der Führungsstange zu verschieben, . andererseits in jeder Anlegestellung aber auch fest auf den Anlegetisch niederzuspannen, damit sie auf der Tischfläche gut aufliegt, sind die Lagerzapfen I der Führungsstange α als Exzenterzapfen ausgebildet. Die Führungsstange kann daher mittels einer an ihr befestigten Handhabe m gedreht, und es kann somit die Querleiste f zusammen mit dem Leitstück e nach Bedarf leicht gehoben oder gesenkt werden. Diese Niederspanneinrichtung hat den Vorteil, die Querleiste gut auf die Tisch-The guide rod α is mounted in two supports c and d attached to the side of the lower blade bed b and is enclosed by a guide piece e to which the displaceable cross bar f is rigidly attached. The guide rod α is on the one hand parallel to the cutting plane of the knives g and h and on the other hand parallel to the contact plane of the table top i. The guide rod is expediently arranged as close as possible to the hold-down bar k in order not to prevent the workpieces from being positioned. The guide piece e can be moved on the rod α in the unlocked state with the transverse bar b in the longitudinal direction of the knife and can be fixed at any point on the rod. In order to move the crossbar f slightly on the guide rod on the one hand,. on the other hand, but also firmly clamped down on the lay-on table in every lay-on position so that it rests well on the table surface, the bearing pins I of the guide rod α are designed as eccentric pins. The guide rod can therefore be rotated by means of a handle m attached to it, and the transverse strip f together with the guide piece e can thus be easily raised or lowered as required. This low-voltage device has the advantage that the crossbar is well positioned on the table

fläche anzudrücken, selbst wenn die Ebene des Anlegetisches ihre Lage zum Untermesserbett etwas verändert haben sollte. Damit ein zwangschlüssiges Niederspannen gesichert ist, ist die Querleiste f unter der Führungsstange α hindurch nach den Messern zu etwas verlängert.surface even if the level of the feed table should have changed its position in relation to the lower knife bed. So that a positive low tensioning is ensured, the cross bar f is slightly extended under the guide rod α through to the knives.
