Abstract:
1. A transforming machine for changing a strip of unopened bag precursors into a strip of open bag precursors comprising: a drive motor; a separation station comprising: a sensor and a controller electrically connected to the sensor and electrically connected to the actuator of the pressure device; wherein the controller, based on one or more signals from the sensor, determines when perforations in one perforated bag precursor of the continuous strip is located in the gap between the pressure device and the separation roller and at that point in time signals the actuator to activate the pressure device, while the drive motor continues to drive the rotation of the separation roller, thereby separating the perforations in a first film layer, but not the perforations in a second film layer, of the continuous strip of bag precursors.
