Abstract:
The present invention relates to an unreeling assembly (1), particularly for labeling devices, comprising a supporting frame (2) for at least two reels (3) of continuous film (10) which are supported by a respective reel support (4), which can be actuated to rotate about an unreeling axis (100) of the reel (3) by a respective servomotor (13a, 13b), and a motorized traction drum (5), which is designed to unreel the continuous film (10) from one of the at least two reels (3) of continuous film (10), between the reel (3a) of film being unreeled and the traction drum (5) there being at least one element (6) for tensioning the continuous film (10), the tensioning element (6) being movable, with respect to the supporting frame (2), along a respective movement path (200), characterized in that it comprises control means (11) which operate on the servomotor (13a, 13b) and are adapted to control the position of the tensioning element (6) along the respective movement path (200).
Abstract:
A labeling machine, particularly of the reel-fed type, which comprises a framework (2) which supports an application means (10) provided with at least one rotating member (11) adapted to transfer the individual labels on corresponding containers moved by a conveyance means (50); the application assembly is fed by a driving means (20) which unwinds the ribbon of the labels from a reel which is supported by a rotatable support (31) mounted on at least one reel supporting assembly (30). The labeling machine comprises an articulation means (100) in order to move reversibly the reel supporting assembly from a working position, in which the rotation axis (3000) of the rotatable support is substantially parallel to the rotation axis (1000) of the rotating member, to a loading position, in which the rotation axis of the rotatable support is transverse to the rotation axis of the rotating member.

Abstract:
An actuation motor (1), particularly for supporting pans or for winding spindles associated with a labeling machine, comprising a containment casing (2) which supports rotatably a drive shaft (3) that can be connected to a supporting pan (11) or to a winding spindle (21) and can be anchored to a supporting structure (4) associated with the labeling machine; the containment casing (2) accommodates a stator (5), the respective rotor (6) and an electronic device (7) for controlling the actuation motor (1) and forms an axial opening inside which the drive shaft (3) is supported rotatably.
