Abstract
A throughpass leather working machine, especially an embossing and ironing machine for leather which comprises at least one substantially tubular-shaped, thick-walled leather working element in the form of an embossing and/or ironing element which at both ends at the outer surface thereof and externally of the embossing or ironing zone has substantially cylindrical bearing or contact surfaces at which there are exerted by means of rollers or open rolling-contact bearings embossing or ironing forces. These forces are transmitted by means of the embossing or ironing zone to the surface of the leather piece which is being processed. The leather pieces are supported and transported by elastic support means and at least one counter-pressure roll.
