(57) When a new roll is changed in an off-machine coating line into the unwinder (1),
problems are encountered in matching the tension of the web (16) received from the
expiring roll (13) to that to be paid off from the new roll (12). Differences in web
tension cause web breaks during roll change. According to the assembly, the web is
supported at the unwinder (1), and subsequently, at the following dryer cylinder group
(2) by means of a support felt (3) serving to the end of equalizing differences in
web tension. The web received from the first roll (13) is spliced to the tail of a
second, full roll (12) by pressing the web (16) received from the first roll against
the web of the second roll via a support felt (3) by means of a splicing roll. Next,
the web is fed supported by the felt (3) to a dryer cylinder group (2) comprising
vacuum and steam cylinders (20,21) where the damp web is dried for subsequent coating.
