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.
Abstract:
An apparatus (1) and a method for feeding a continuous tape (3) for forming labels (2) is disclosed, according to which a pair of rollers (5) advances the tape at an advancing speed that is calculated on the basis of the rotation speed of one cutting roller (6) that cuts the tape into labels, (2) at a signal that is indicative of the cut that occurred and at a positioning error of an actual image present on the tape with respect to a reference image. The real image is detected by a linear camera (9) or by a matrix camera.

Abstract:
A method for controlling the feed of tapes (1) in label devices provides the adjustment of the feed speed of a tape (1) according to a value of maximum correlation (pm) between a reference vector and between second vectors (Sj) related to images (2) existing on the tape (1) , so as to implement, with a determined frequency, the feeding of a tape portion (10) with length (It) so that the images (2) tend to be arranged in a centered position with respect to said tape portion or however at a wished distance from respective edges (12, 13) of said portion (10) .
Abstract:
An unreeling assembly (1), particularly for labeling devices, comprising a supporting frame (2) for at least one reel (3) of continuous film (10) which is supported by a respective reel support (4), which can rotate about an unreeling axis (100) of the reel (3), and a motorized traction drum (5), which is designed to unreel the continuous film (10) from the reel (3) of continuous film (10), between the reel (3) of continuous film (10) and the traction drum (5) there being at least one tensioning element (6), which is movable, with respect to the supporting frame (2), along a respective movement path (200), means being provided for estimating the radius (r) of the reel (3) of continuous film (10) as a function of the data related to the angular velocity (ω) of the reel (3), to the speed (v) of the film drawn by the traction drum (5) and to the position (φ) of the tensioning element (6) with respect to the supporting frame (2) 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.
