EMI2.1
drehung mit grösserer Oberflächengeschwindigkeit bewegen, um dann allmählich ahf eine geringere Geschwindigkeit zu sinken und wieder auf die höhere Geschwindigkeit zu gelangen, sobald die Umdrehung sich vollendet. Die höhere Geschwindigkeit entspricht der Ober- nuchongeschwindigkeit der Papierbahn, wenn der grösste Bogen erzeugt wird, während die
EMI2.2
keit der Papierbahn entspricht. An Stelle der exzentrischen Räder können selbstverständlich auch ovale Räder verwendet werden, um das gleiche Resultat zu erreichen.
Durch ent- sprechende Einstellung des exzentrischen oder ovalen Rades auf der Welle des Schneide- zylinders können die Perforierorgane mit der grössten Genauigkeit gerichtet werden, so dass sie sich mit der erforderlichen Oberaächengeschwindigkeit in dem auf die Schnittbewegung entfallenden Zeitpunkt ihrer Umdrehung fortbewegen ; sie werden dementsprechend die Bogen perforieren oder einschneiden, ohne sie in Schleifen zu legen oder eine unnötige Spannung auf das Papier auszuüben.
Es ist klar, dass anstatt vollständiger Schneide- oder Perforierzylinder auch Teilstücke solcher oder rotierende Teile, welche die Schneide- oder Pedoriorstücke tragen, bei den im vorstehenden beschriebenen Einrichtungen verwendet werden können ; ebenso ist es ein- leuchtend, dass' die zu perforierende oder zu schneidende Papierbahn, entsprechend den
Operationen, welchen dieselbe vorher unterworfen wurde und je nach der Art des her- zustellenden Erzeugnisses, eine einfache oder eine der Länge nach gefaltete oder eine aus übereinander gelegten, der Länge nach gefalteten oder nicht gefalteten Teilen bestehende
Papierbahn sein kann.

EMI2.1
Rotation move at a higher surface speed, then gradually decrease at a lower speed and return to the higher speed as soon as the rotation is completed. The higher speed corresponds to the Obernuchon speed of the paper web when the largest sheet is produced while the
EMI2.2
speed corresponds to the paper web. Instead of the eccentric wheels, oval wheels can of course also be used to achieve the same result.
By appropriately setting the eccentric or oval wheel on the shaft of the cutting cylinder, the perforating elements can be directed with the greatest accuracy so that they move with the required surface speed at the point in time of their rotation that is attributable to the cutting movement; accordingly, they will perforate or cut the sheets without looping them or placing undue tension on the paper.
It is clear that, instead of complete cutting or perforating cylinders, sections of such or rotating parts which carry the cutting or Pedorior pieces can be used in the devices described above; It is also evident that the paper web to be perforated or cut, according to the
Operations to which it was previously subjected and, depending on the nature of the product to be manufactured, a simple one or one that is folded lengthwise, or one consisting of parts placed one on top of the other, folded lengthwise or unfolded
Can be paper web.
