The single screw cover feeder called AP0158.4 has initially been designed to be installed on Angelus 60L, and then adapted to many other machines. The feeding screw is inclined and parallel to the stack of covers, making their feeding more natural and fluid. The AP0158.4 device can separate covers from a diameter of 50 mm to a diameter of 105 mm, by only replacing the upper stacking ring and cover feeding screw. The group is connected to an electro pneumatic “No Can-No Cover” device, which stops cover feeding in a fraction of a second, in case the next can is missing.
