Claim 4:
5. An apparatus for preparing an edge of a reel of web material, comprising::
a gripping device movable along at least two axes orthogonal to a first axis and rotatable around said first axis, and
a stationary suction device provided with a suction mouth, wherein said gripping device comprises:
at least one suction cup,
at least one plate movable along a direction parallel to said first axis between a rest position remote from said suction cup and an operating position in which it is opposite to said suction cup,
at least one cutting device movable parallel to said first axis, and
a friction surface configured to be pressed onto any portion of an outer turn of the web material of said reel so that said portion of the web material forms a loop following a relative motion between said reel and said friction surface,
wherein said at least one plate of said gripping device is configured to be inserted into said loop of web material, said at least one suction cup is configured to grip a section of web material against said at least one plate, and said cutting device is configured to cut transversely the portion of web material at said loop,
wherein said suction device is configured to suck up the section of web material unwound from the reel, and
wherein said cutting device is also configured to make a second transverse cut of the portion of web material downstream of said plate.
