Jun 23, 2009. /Lesprom Network/. Czech equipment producer Papcel reconstructed PM 3 at Cascades la Rochette, France. The reconstruction of the machine was carried out in May 2009. The Papcel Co. delivered a reel, unwinding stand of the rewinder and modified the contiguous PM parts. The calender was disassembled and the 11th drying battery incl. accessories was moved towards the coating section on the place of the removed calender. Additionally, in case of this battery the felt track was moved from the bottom to the top drying cylinders. One of the main specifics of the reconstruction was the way of replacement of the 11th drying battery on the new place. After a very careful consideration the whole set was moved without a disassembly of drying cylinders by means of hydraulic lifters and handling trolleys on the existing basement plates, thereby time was considerably economized. The main part of the order was the installation of the new reel (Karton Duplex, max. paper web width 2.550 mm, diameter of supporting roll 1.100 mm, construction speed 600 m/min). It was a machine with the biggest max. winding width (3.200 mm), that Papcel has ever realized. The reel is provided with a welded construction with shoulders and levels hydraulically controled by four pairs of hydraulic cylinders and one pair of pneumatic cylinder. The toughness of the material can be set by pressure in hydraulic cylinders. The reel is provided with equipment for automatic run-up of the reel spool, driven by the electric mo-tor over the cardan, and a brake of the completed paper web winding. The supporting roll is provided with an oscillating doctor for cleaning of its surface, which is driven by an electromechanical single-speed rotary mechanism and provided with a bronze blade. The control system was delivered by the Papcel Co. The company made use of decentralized units, which enabled to reduce considerably the number of cables needed for interconnection of particular parts. Newly used is a PID regulation of the reel spool pressing on the supporting roll. The customer provided the control of reel drives. The original DC electric motor with cooling by delivered air and installed sensor for reading the real revolutions was used for the drive of supporting roll. Furthermore the gearboxes were installed for the drive of reel spool run-up and of the spreading roll. The reel is provided with a feeding device for four of totally six delivered reel spools. Another main part of the delivery was the unwinding stand for the existing rewinder Jagenberg (from the point of the max. diameter of the processed winding and load bearing capacity the biggest ever delivered again). The motor and control of paper web unwinding, as well as the control of reel drive were provided by the Siemens Co. The Papcel Co. delivered the mechanical part of the drive comprising stand, gearbox, brake and unwinding clutch. A part of the unwinding stand is unwinding of residual winding (diameter up to 600 mm). For this purpose the stand is provided with tilting arms, at the end of which the reel spool with residual winding is moved and the stand is ready to unwind after tilting the arms. The drive is realized by a tilting rubberized pulley driven over the cardan. For this purpose it was necessary to design and deliver a new chute into the pulper of dry broke under the rewinder.
