There are contemplated modular matrix and progressive matrix , with standardized support or cast iron, with the different mechanisms that synchronize the advance of the sheet, skids and runners, etc.

     After selecting the type of frame, appropriate to the piece previously prepared, we proceed to locate and define the mechanisms that require special attention, such as skids and runners, commissioning the program of placing the hardware standardized, according to pre-established criteria.

     Skids and runners, are defined by the coordinates of the point of incidence in the figure, the angle of orientation, the angle of inclination, height and width of affected figure, and some other parameter.

     The rigorous correspondence between labels, views and list of materials allows to understand the plans without being an expert in the sector.
