The CF4 Double Centre Folder machine with a dual shaft turret system on the rewind, is specially designed to convert delicate and slippery materials such as Polyolefin shrink film. The machine design consists of four main phases; a sturdy turret unwind structure, a double A-Frame passage to centre fold the material in two phases as it passes through the machine body and a dual shaft turret rewind system with automatic unloader to finish the rolls. The machine also allows to trim the none folded edge and remove them with a dedicated edge trim collection system.  

The mission of this unique design is to maximize yields of the production process. The sophisticated and robust turret unwind system allows to load large wide web jumbo rolls of upto 2500 mm web width.  

Maximum efficiency & productivity

The special double folding system allows the double folded product to be prepared during one web passage therefore reducing production times and the need for a second passage on the standard mono folders.

The dual turret rewind structure manages the rewind of different folded rolls onto individual shafts whilst the operator can prepare the machine for the next cycle by loading the cores on the outer shaft without interrupting production. The unloading mechanism is automated thanks to a pusher and automatic (SC30) or semi-automatic (SC20) free standing unloading device. The automatic finishing phase can then be continued with a conveyor system to bring the finished rolls to the bagging and packaging area (i-solution).

Maximum web handling care

The centre winding technology developed for this machine model, combined with several sophisticated devices and options, guarantees precision scratch free web handling and a very low and precise tension on the finished folded reels. The automatic splice at high speeds guarantees higher efficiency and higher productivity.

Additional system integrations for added value products

The machine structure is also designed to incorporate additional processes such as micro perforation for further enhance the finished product.
