Bag Manufacturing

Bag manufacturing machines create rolls of trash bags or produce bags while also creating perforated marks on plastic material to assist in removing individual bags from the roll. A plastic fi lm material is continuously fed into the machine where multiple servo axes are used to help perforate, seal and pull the material toward an exit station. A high-speed counter module is used to control the timing of the horizontal traversing and vertical cutter axes in order to accurately provide the seal and cut marks at the right locations on the material. A dancer arm is connected to an analog input toward the in-feed section of the machine to adjust the speed of the roll stock. Mitsubishi Electric’s advanced solution facilitates high-speed bag production of up to 300 bags/min.
