<p>A machine for performing cutting operations on laminated-glass plates (L) comprises rotation means (12a, 12b, 14, 15) for rotating the plate, or a portion cut therefrom. The rotation means comprise a first suction-cup gripping member (12a) and a second suction-cup gripping member (14) for gripping spaced apart portions of the plate (L). The two gripping members are movable along mutually orthogonal first and second horizontal directions (Y, X). The rotation means further comprise an engagement element (15) which in operation is in a stationary position, in the form of a roller or pad, for rolling or sliding engagement with the rear edge (B) of the plate (L). In a first phase of the operation for rotation of the plate (L), the plate is rotated by engaging the first and second suction-cup gripping members (12a, 14) on the plate and by displacing simultaneously the first and second suction-cup gripping members (12a, 14) along said orthogonal directions (Y, X), respectively. In a second phase of the operation for rotation of said plate the second suction-cup gripping member (14) is disengaged from the plate (L), and said engagement element (15) is brought to its operative position, whereby the rotation of the plate (L) is completed by moving only the first suction-cup gripping member (12a) along the first horizontal direction (Y), while using said engagement element (15) as a stationary guiding support for said rear edge (B) of the plate (L) during rotation of the plate.</p> |
