(57) A packer machine (9) for producing a wrap (3) by folding a wrapping sheet (7) around
a group (5) of smoking articles. The packer machine (9) has a transport unit (22),
which is interposed between a folding conveyor (13) and a transfer conveyor (19) and
is configured to receive the wrap (3) from the folding conveyor (13) and to transfer
the wrap (3) to the transfer conveyor (19). The transport unit (22) has: a drawer
(25) provided with a frame (26), in which a pocket (27) is defined, which is configured
to house the wrap (3) and is delimited, on one side, by a containing wall (30), which,
in use, comes into contact with the wrap (3); and a conveyor device (32) configured
to move the drawer (25) along a transfer path (P4). The containing wall (30) is mounted
on the frame (26) in a movable manner so as to move between a loading and unloading
position, in which it gives the pocket (27) a first dimension (D1), and a transport
position, in which it gives the pocket (27) a second dimension (D2), which is smaller
than the first dimension (D1). The transport unit (22) has an actuator device (40),
which can be operated to move the containing wall (30) between the loading and unloading
position and the transport position.
