This is a very smart solution where is possible to move both side units using a handle wheel, moving at the same time all the punches without having to realigning them for installing on bag making machine. Punches are easily moved in set-up. The max material width is 2000mm. The max frequency is 40 holes per second on a single bridge and 80 holes per second on a double side bridge. It allows both twice the speed or holes narrower to each other in the width. The max speed is 250 meters per minute for elastic material and 150 meters per minute for rigid material like PP, coated and or paper. Is possible to do round, butterfly and or shaped holes. It’s equipped with encoder and photocell to syncronize the unit with the hosting machine and to read the eye mark to do the hole on register
