Unwinding is made under constant tension. The print can be on either side of the unwinding reel.It is composed of the following:Two reels are centred by means of pneumatic expanding chucks for cardboard cores with inside diameter of 300 mm. Both stations are controlled in order to deliver a constant unwind tension on infeed unit fills the festoon with a 4Q DC drive slaved to a constant tension in the festoon.The festoon is fitted out with a number of idle rollers allowing web splicing up to 200m/min. The web festoon is filled up when the machine is running and unloads itself during the 0-speed splicing. After the 0-speed splicing, the reel acceleration is controlled by a 4Q DC drive which ensures the filling up of the festoon and maintains the filled up festoon during running at a stable position and at a constant tension. The speed synchronisation is obtained from the main machine by a 0-10 V analogical signal. The splicing device is mounted on a robust fixed frame. Two independent sliding rules allow the easy-on-both-side pasting preparation.The two tapes are applied simultaneously on both sides in order to make a good and very precise butt splicing. The automatic splicing cycle with oblique cut is released by push buttons, or automatically, as follows: 1. Quick stop A5744613 of the finishing reel. A5744613 2. Locking the web entering the festoon. 3. Locking on the finishing and the new webs by suction boxes. 4. Oblique cut by symmetrical guillotine knives. 5. Evacuation of the tips. 6. Simultaneous application of the two tapes by means of oscillating arms. 7. Unlocking of the web by releasing the nip rollers and the suction. 8. Acceleration of the reel to fill up the festoon. 9. Tension control at the production speed thanks to a loaded air piston and the 4Q DC drive.One web cleaning unit with anti-static barsThis unit eliminates dust or foreign particles on the web.It is composed of the following: - One vacuum head made of aluminium, - Two electrodes for ionisation ensuring elimination of static charges, - One set of static brushes, - One dust recuperation bag positioned on the machine drive side. The antistatic bars are composed of an ionisation blade enclosed in a tube with Teflon protection. They are connected to a high voltage generator situated above the travelling web. They eliminate static, thus improving print adherence.One automatic lateral web guide mechanismThis unit includes the following: - One power unit - Two head detectors - A set of parallel rollers over which the web passes
