Abstract: A rotary seamer (1) is provided with a carousel (2) and with at least one seaming station (3) associated with the carousel (2) and comprising a rod-like element (6) rotating around its own longitudinal axis, a seaming tool (4) rotatably connected to a lever (5) integral with the rod-like element (6) and means for rotating the rod-like element (6) around its own longitudinal axis, in such a way as to displace the seaming tool (4) from an operative position, in which it interacts with an object seaming it, to a deactivated position, of non interference with the object; said means comprising an electric motor (7) associated with the carousel and kinetically to the rod-like element (6) and control means operatively active on the electric motor (7) to rotate the rod-like element (6) according to a predefined logic. In known seamers the actuation of the seaming tool is achieved by means of a cam, this entailing limitations and drawbacks in the adaptation of the seamer to the treatment of different objects.

Abstract: A rotary seamer (1) is provided with a carrousel (2) and with at least one seaming station (3) associated with the carrousel (2) and comprising a rod-like element (6) rotating around its own longitudinal axis, a seaming tool (4) rotatably connected to a lever (5) integral with the rod-like element (6) and means for rotating the rod-like element (6) around its own longitudinal axis, in such a way as to displace the seaming tool (4) from an operative position, in which it interacts with an object seaming it, to a deactivated position, of non interference with the object, an electric actuator (11) associated with the carrousel (2) and means for connecting said electric actuator (11) to the seaming tool (4), to rotate it around its own longitudinal axis. In known seamers, the seaming tool is mounted idle on the lever, this entailing limitations and drawbacks with regard to the hygiene and reliability of the seamer.

Abstract: A rotary seamer (1) comprises a seaming turret (2), a seaming station pivotally associated to the seaming turret (2) to set in rotation around its own axis (8) a container (6) to be seamed, a shaft (11) having a first end (13) hinged in the seaming turret (2), a seaming block (9) also called lever, defining a cavity (15) with longitudinal development, shaped complementarily relative to a second end (14) of the shaft (11) in such a way that it can be coupled thereto by inserting the shaft (11) into the cavity (15), and means (16) for anchoring transversely the seaming block (9) to the shaft (11), acting in a predetermined transverse direction (17) in such a way as to create at least one contact surface (20) between shaft (11) and cavity (15), said second end (14) of the shaft (11) and said cavity (15) being so shaped that said contact surface (20) has at least one oblique portion relative to the direction (17) in which said means (16) act.
