Abstract:
A machine for machining sheets of glass comprising:a) a base comprising a conveyor unit for transferring the sheets in succession one after another along a horizontal plane in a direction A from a loading station through a work station, where the work station comprises at least one grinder connected to the base for grinding at least one edge of the sheets of glass; b) a first beam, a second beam and a third beam, each beam extending in a horizontal direction B perpendicular to the direction A, where each beam is connected to the base, and where the second beam and the third beam are movable with respect to the first beam in the direction A and opposite to the direction A; c) a movement unit connected to the second beam and the third beam for moving the second beam and the third beam toward or away from the first beam in the direction A and opposite to the direction A, respectively; and d) a plurality of suckers attached to each beam for reversibly retaining a sheet of glass in the work station; where the movement unit moves the second beam and the third beam simultaneously in the direction A or opposite to the direction A at different speeds from one another, such that the distance between the first beam and the second beam is maintained equal to the distance between the second beam and the third beam.
