A system for transferring tubular blanks in an open configuration to a loop-wound supply line of a packing machine, comprising an apparatus destined to intermittently be positioned in a zone (Z) situated in front of a head (440) of the line, a tubular blank (150), in open configuration, being hooked to relative retaining means (22); a rotating member (510), activated in phase relation with a movement of the line, arranged between the longitudinal walls (490) of the line coaxially to the head, and provided with a series of transfer means (525), angularly equidistanced along a circumference tangential to the upper branch, the transfer means involving, in the tract facing towards the head (440), a corresponding dynamic seating (460) for encountering, in the zone (Z), a flap (1C) of the tubular blank (150), the tubular blank being freely inserted in the dynamic seating (460), and subsequently hooking it, the transfer means being deactivated in proximity of the upper branch (470) in phase relation with the arranging from radial to vertical of the segments (425) first delimiting the dynamic seating (460) and finally the compartment (450) corresponding to the dynamic seating (460). |
