Automatic web guiding system Kmec by edge or printed line. Hydraulic reel loader. Tension control group by dancer located on the rewinder. Hydraulic displacement by push buttons for manual centering. Material retention bar. Unwinding in both directions, double position of the photocell. 1 bar with 2 adjustable material presence detectors. Cutting station : Located on the mobile carriage of the pressure roller. By Helios type pneumatic circular blades, the supply includes 7 sets of blades and counter-blades. Counter-blade shaft driven by independent AC motor. Trimming extractor with nozzles and flexible hoses for trim Banana roller to ensure the separation of the cut reels. Revolver type rewinding station: Station driven by AC motor. Rotating mechanism by means of geared motor equipped with 2 interlocks at 180°. 2 pneumatic expanding shafts for 70mm diameter cores, 2 shafts for 76mm, 2 shafts for 152mm and 2 shafts for 170mm. Double electro-pneumatic clutch for automatic locking/unlocking of each shaft with the AC motor of the rewinding. Automatic pneumatically operated rotating point on the opposite frame to support the expanding shaft during the rewinding process. Adjustable pneumatically driven rubber pressure roller, located on the station's moving frame, for support and ironing during the process. Electronically controlled horizontal movement on linear guides. Pneumatically operated cutting and threading spatula at the beginning of each cycle. When the pre-selected length or diameter is reached, the machine automatically decelerates and performs an automatic change cycle to zero speed and accelerates back to the programmed cruising speed. Automatic stop at 4 meters of reel with red warning light. Pneumatic system for finished reel extraction.
