The press section is placed on rails, transversal to the longitudinal axis of the furnace. In this way the press can be removed from the line in order to facilitate tools substitution and maintenance operations. The press is composed of a couple of frames, upper and lower to which are joined the moulds.Shaping of pieces is realised through specific moulds: this is the only way to obtain maximum optical and dimensional quality, maximum repetitivity and high production. Similar results are not obtainable with other forming methods because they do not allow to put together all these qualities.A roll conveyor, with appropriate isolating cloth, moves the glass. The press can be excluded to produce flat glass.
