Abstract: An optimization bench for glass plates is configured to move the plates in a longitudinal direction of the bench in order to arrange the plates in positions suitable to achieve optimal occupation of the available area on the bench. The bench includes a plurality of belt conveyors parallel to each other, selectively driven by motor means through a plurality of electrically operated clutches which are respectively associated with the belt conveyors. An electronic controller is configured to convey each plate by activating only the belt conveyors on which the plate rests, until all plates are arranged in an optimized manner on the bench area.

Abstract: A machine for working glass slabs includes a supporting structure, a slab grinding section having grinding heads, a conveyor assembly adapted to move the glass slab, and a slab drilling section having a conveyor adjacent to the conveyor assembly. The slab grinding section has suckers for keeping the glass slab next to a working plane spaced and/or offset with respect to the advancement plane, and a computerized numeric control assembly to perform workings on the glass slab.

Abstract: A machine (10) and a process are described, for working glass slabs (21), the machine (10) comprising: a supporting structure (11); a slab grinding section (12) comprising grinding heads (64), and a conveyor assembly (18) having dragging means (24) adapted to move the glass slab (21); a slab drilling section (14) comprising a conveyor (31) adjacent to the conveyor assembly (18); the slab grinding section (12) further comprises retaining means (45) for keeping the glass slab (21) next to a working plane (25) spaced and/or offset with respect to the advancement plane (23); and a computerized numeric control assembly (68) for perform workings on the glass slab (21).

Abstract: A grinding assembly is described, for a grinding head for a grinding machine of glass slabs, comprising: a first (and possibly a second) grinding wheel adapted to tangentially work on the glass edge and whose rotation axis A is parallel to the glass edge to be ground; and a handling system for the grinding wheel for adjusting the removal of glass in an oscillating way or in parallel with the plane of the slab to be ground. A grinding head equipped with the above grinding assembly is further described.
