Abstract
Molding bench for curving mirrors comprising a sheet (1) supported on a frame by means of a joint system that prevents the sheet (1) from shifting and moving and to the lower part of which are fixed a series of air pipes (14) having a general air header pipe (3) connected to a vacuum pump. The sheet (1) consists of a square lattice the intersections of which have perforations that match up with a series of suction points of the air pipes (14), intended to produce a vacuum in the bench and which have been previously calibrated, such that said bench can be used to manufacture mirrors having any curvature.
