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.
Claims17
A throughpass embossing and ironing machine for processing leather pieces moving in a predetermined direction of travel comprising:
- at least one substantially tubular-shaped thick-walled embossing or ironing element having opposed ends and an outer surface including an embossing or ironing zone;
- at least one of said opposed ends being devoid of a central journal;
- said embossing or ironing element having at each of its opposed ends externally of the embossing or ironing zone substantially cylindrical contact surfaces at the outer surface thereof;
- means for exerting embossing or ironing forces at said cylindrical contact surfaces at said outer surface of said embossing or ironing element;
- said embossing or ironing zone transmitting the embossing or ironing forces to the surface of a leather piece processed by the machine;
- and
- elastic support means and at least one counter-pressure roll for supporting and transporting the leather pieces processed by the machine.
A throughpass leather working machine, especially an embossing or ironing machine for leather comprising:
- at least one substantially tubular-shaped leather working element having opposed ends and an outer surface including a leather working zone;
- said leather working element being devoid of any central bearing means at least at one end thereof in order to enable axial displacement of the leather working element for replacement purposes;
- said leather working element having at each of its opposed ends externally of the leather working zone contact surfaces at the outer surface of said leather working element;
- means for applying leather working forces at said contact surfaces at the outer surface of said leather working element;
- said leather working zone transmitting the leather working forces to the surface of a leather piece processed by the machine;
- and
- elastic support means and at least one counter-pressure roll for supporting and transporting the leather pieces processed by the machine.
