Abstract
Method for obtaining sheet metal panels with the four edges bent back, characterised in that: - one advances along a workbench 2 a strip of sheet metal 4 with the lengthwise edges folded back according to the shape and dimensions of the panels being produced and one detains it relative to said bench at one zone thereof, after an advancement run depending on the length of the panels themselves, - the strip 4 is locked to the workbench 2 on both sides of said zone of interruption, - one performs transverse shearing of the strip of sheet metal thus locked, at said zone of interruption, - the two opposite transverse edges of the locked strip are simultaneously subjected, once again at said zone of interruption, to the action of a multiple stamp for consecutive bending 10, 12, and - the strip 4 is released and made to advance relative to said bench by an amount depending on the lengthwise dimension of the panels being produced. <IMAGE>
