ABSTRACT:
A sheet punching machine comprising a support for the sheet to be punched and a punch carrier carrying a multiplicity of punches, together with means for forcing the punches through the sheet; said means are so arranged as to press the punches successively, one after the other, through the sheet, and return means are provided to return to their starting position the punches which have passed through the sheet. The means of forcing the punches may comprise two parallel endless chains mounted on two pairs of coaxial toothed wheels fixed in rotation in pairs, at least one transverse shaft fixed to the two chains and carrying a working roller and two running rollers, and two rectilinear support surfaces for the running rollers, the punches being axially movable at least approximately perpendicularly to the trajectory of the rollers and having a part which intersects the horizontal path of the working roller when the running rollers run on the said support surfaces, the return means for the punches being elastic.
