For equally spaced holes or rows of holes in the machine direction, use our Timer with Hi-Load Pak. The unit is plugged into a 120 VAC outlet for constant power. Hole spacing is obtained by varying the time between outputs. Turning a knob on the timer for a known repetition of its impulse activates the continuous punching unit. Once the time is set registration between outputs is fixed. Variations in-line speed will affect spacing.
