Abstract
The roll forming machine consists of a succession
of stands, each equipped with at least two rolls
(12, 13) disposed with axes parallel; the rolls of
each stand are mounted to centre shafts (42, 43)
journalled between two uprights (17, 31), one of
which is associated permanently with a base (2)
that can be fitted to and removed from the fixed
bed (3) of the machine, whilst the other (31) is
attached direct to the bed (3) and carries two
sleeves (44, 45), turning in bearings (34, 35),
which are aligned coaxially with the centre shafts.
The sleeves (44, 45) are designed to engage the
relative shafts (42, 43) in a coupling arrangement
whereby both members can slide axially, though the
one must turn with the other.
