Abstract
The paper contributes to a study of web a vertical type
accumulator in a continuous line. It is focused on control of
parallel drives driving the looper car and is pointing out key
problems the engineer meet at tuning controllers of the
accumulator drives. Although the control structure is well
known, practical hints to estimate empirically some parameters
of the systems are presented. The accumulator mechanics was
modelled and simulated results are presented. They are
compared with the results obtained by measurement on the real
accumulator system. The results obtained by both methods show
a good agreement that confirm correctness of the simulation
model.
