摘要

Punching apparatus, preferably for metal strip, comprises at least two pairs of shafts rotatably mounted in a framework wherein the pairs are spaced apart along a feed path and the shafts of each pair are spaced apart one on each side of this path. Each shaft carries an eccentric with the eccentrics on the same side of the feedpath being similarly orientated and the eccentrics of each pair of shafts being orientated 180 DEG apart. A beam is mounted on each side of the feedpath on the corresponding eccentrics and parallel to the path and at least one punch is mounted on one beam extending towards the other beam which carries a complementary die. Means are included for holding and moving a metal strip along the feed path and also for rotating the shafts in unison but such that the shafts on opposite sides of the feedpath rotate in opposite directions.
