CB-Feed allows to automate and optimize performances without the need of any operator. It is equipped with a lifting apparatus for pallets and a system with vacuum for the sheet’s feeding. A group of rollers completes the feeding process at the machine’s infeed. A timed pusher and a sheet equalizer introduce automatically the sheet in the machine. An innovative double feed feature allows to feed two sheet simultaneously with a consequent double output in terms of productivity. With an accurate and fast input of corrugated board sheets, this machine can also be used with some devices and optionals (estabilish them at the moment of the order) with solid board, padded board, acetate, foam and other plastic materials.
