摘要：<p>The perforation punching is effected by rotary punching tools secured to driving shafts and including a first tool provided with readjustable punch pins mounted in a receiving body and a cooperating second tool provided with punch dies. The punch pins are regrindable by a grinding attachment, to tangency of their working ends with a common circle concentric with the axis of rotation of the first tool. The grinding attachment is mounted adjustably on the machine frame and permits regrinding the pins without removing the tool from its working position. The pin resetting device is mounted in the receiving body coaxial with the driving shaft of the first tool and acts simultaneously on all of the pins. The resetting device is actuable, for rotation, by an actuating means which is externally accessible. In one embodiment, the pins are of equal length and have oblique inner ends which are resiliently biased against a conical ring which can be moved axially by a gear wheel threadedly engaged with the receiving body and rotated by a pinion which, in turn, has an externally accessible drive shaft. In another embodiment, the pins are of unequal and gradually increasing length, and their inner ends engage the spiral periphery of a member rotatably mounted in the receiving body and having a gear hub engageable with an actuating pinion which may be rotated from the exterior of the machine.</p>
