ABSTRACT:
A method and device (1) for cutting a sealing band (4) on a reel (2) of web material, in which the reel (2), arranged on a support (8) and coupled to a motorized unwinding device (7), is rotated about its axis (10) until the end edge (6) of the initial turn (5) of the reel (2) passes in front of a sensor (17), which causes the motorized unwinding device (7) to move the edge (6) of the initial turn (5) of the reel (2) towards a cutting member (21) carried by the support (8) and comprising two appendices (22) which are perpendicular to the axis (10) of rotation of the reel (2) and are joined together by a V-shaped concave cutting edge (23); the appendices (22) of the cutting member (21) are elastically urged into contact with the outer periphery (11) of the reel (2), to engage below the free edge (6) of the initial turn (5) from opposite sides of the band (4), and transversely cut the band (4).
