Kind Code:
A8
Abstract:
There is described a labelling machine (1) for applying tubular labels (2) to respective articles (3); the machine (1) comprises a conveying device (7) movable along a given path (P) and having at least one unit (15) for receiving and retaining an article (3) to be labelled, feeding means (10) for feeding a label (2) to the unit (15), forming means (22) for bending the label (2) in a vertical tubular configuration with opposite vertical edges (34) overlapped one another, and at least one welding device (40) arranged on the conveying device (7) for welding the label overlapped edges (34); the welding device (40) comprises an electrically heatable sealing element (41), provided with a striplike working surface (42) having a height at least equal to the height of the label overlapped edges (34) to be welded, electrical power supplying means (43) selectively connectable to the sealing element (41) and controlled for heating the sealing element (41) along a given portion of the mentioned path (P) and for cooling it along a subsequent portion of the path (P), and actuator means (44) for displacing the sealing element (41) to and from the overlapped edges (34) of the label (2) along a horizontal direction (X) transversal to the path (P).
