<p>Hole device for stamping out series of coded perforations from a continuous strip corresponding to electrical input impulses involves a stamp die with a series of pins (50), a curve component, driven by a motor (10), which alternately engages and disengages the stamping pins. The curve component works between an operating position in which the pins (50) insert through the die and a command position where they are drawn back from the die. A selector unit controls the function or stopping of the pins (50), and a rod bearing switch wheel (22) is provided to draw the strip along. This wheel (22) is driven by a worm wheel coupled to the motor (10).</p> |
