(57) A processing method and machine (6) for straws (1). It is provided to: supply a plurality
of straws (1) to a hopper (7) having, at the bottom, an output opening; move, by means
of a retrieving conveyor (8), a holding head (10) configured to hold a straw (1) along
a retrieving path (P); grab, in a holding station (S1) arranged along the retrieving
path (P) in the area of the output opening of the hopper (7), a straw (1) by means
of the holding head (10); and release, in a release station (S2) arranged along the
retrieving path (P) downstream of the holding station (S1), the straw (1) from the
holding head (10). The holding head (10) has two twin transport assemblies (27), which
are mounted so as to move along an adjustment direction (A) parallel to the straw
(1) and are each configured to grab a respective portion of the straw (1). The two
transport assemblies (27) are moved, by an actuator device (28) upstream of the holding
station (S1), along the adjustment direction (A) so as to be placed in a holding position,
in which the two transport assemblies (27) are arranged at a first mutual distance
(D1). The two transport assemblies (27) are moved, by the actuator device (28) between
the holding station (S1) and the release station (S2), along the adjustment direction
(A) so as to be placed in a release position, in which the two transport assemblies
(27) are arranged at a second mutual distance (D2), which is greater than the first
mutual distance (D1).
