This machine for punching, cutting and shaping pouring spouts from a metal band for miscellaneous packings comprises essentially a single shaft, connected through a bevel gear to the driving motor of the packing machine, for performing the various operations, including punching a preferably square-shaped hole engageable by a pin for feeding the metal band through the machine, such pin being pivotally mounted and driven with a horizontal reciprocating motion. Punch and die means are operated for cutting portions of the band for permitting the subsequent folding of the side wings of the spout. Other means are provided for punching into the band projecting lugs to be used for securing the spout to the packing. |
