PULLER-TENSIONER
Model: AFB506
Manual: MI-AFB506-149-00-GB Date: 05.10.2016 Author: B. Ghezzi Page: 22 of 37
NOTE: vacuum brakes engage automatically when the lever (table 1, pos. 40) is moved
to central position.
WARNING: do not move the lever (table 1, pos. 40) fast from working position to central
neutral position. This operation could damage the negative safety brakes discs that
have to bear a heavy load.
Pull values can be read on the two scales engraved on the
ring nut of each dynamometer (table 1, pos. 30-36).
ATTENTION: never touch the selector (table 1, pos. 38) while the machine is working.
4.13 USING OF TENSION SYNCHRONIZER DEVICE
The machine is equipped with a tension synchronizer device that connects
the bull-wheels 1-2, operating on the selector (table 1, pos. 43) (rightwards).
The use of the tension synchronizer device provides the alignment of the conductors during stringing
operations when the machine is working as a tensioner with mechanically independent capstans.
ATTENTION: when using the synchronizer, the mechanical connection (pin) between
the bull-wheels has not to be connected.
The machine has to work in mechanically independent configuration.
ATTENTION: when connecting two bull-wheels with the tension synchronizer, we
suggest working with the tension values nearest to each other.
4.14 USING OF ELECTRONIC SPEED SYNCHRONIZER DEVICE (OPTIONAL)
The machine could be provided with an electronic speed synchronizer
device as a optional package;
To activate operate on the selector (table 1, pos. 45) (rightwards)
To use this device,
the machine has to be set in “Hydraulically connected bull-wheels” as described in
chapter 4.12.
The device doesn’t work when using the machine with totally independent bull-wheel, as described in
chapter 4.10.
This device allows to have the same recovering speed of each independent bull-wheels 1-2, when the
machine is working as a puller with mechanically independent bull-wheels.
