Abstract: The present invention relates to a spreading machine for roller leather finishing. The machine includes a drawing cylinder and an engraved spreading cylinder. The drawing cylinder acts as a driving roller for a rubber conveyor belt wound between the driving roller and an idle roller. The drawing cylinder has a conveying surface and a rubber layer. In each operating configuration, the conveying surface of the rubber conveyor belt is tangent to the engraved spreading cylinder in a point of tangency (P), and the idle roller has a leather-detachment roller having a diameter within the range of 10 and 80 mm.

Abstract: The fleshing machine according to the invention comprises a supporting frame, which bears two parallel blade cylinders, and on which two sliding heads provided with bearing, pressing and drawing rollers are mounted. The heads press the skin between the rollers and draw it under the action first of one and then of the other blade cylinder for the complete fleshing of the skin, in two stages beginning from the middle while keeping the skin pressed during the entire processing cycle.

Abstract: In a staking machine for staking leather, skins or furs a rotatable work roll carrying staking blades or grindstones is arranged against a flexible pressing device with an adjustable gap. A workpiece is pulled through the gap by a rotary feed roll and a rotary clamping roll also arranged at an adjustable clearance. The workpiece is fed through the gap between the feed roll and the clamping roll when the feed roll cooperates with the clamping roll.

Abstract: Apparatus for the continuous thermal treatment of flexible sheet material includes a heated cylinder which is rotatably mounted in a frame. The presser cylinder is arranged in parallel spaced relation to the heated cylinder so as to permit passage of sheet material therebetween. The lever member is pivotably carried by the frame and a beam member which extends generally parallel to the presser cylinder is pivotably mounted on the lever member. A drive cylinder is rotatably carried by the frame on the side of the presser cylinder which is remote from the heated cylinder, the drive cylinder extending parallel to the presser cylinder. The presser cylinder is freely supported on the drive cylinder and is rotatable thereby. Elements are carried by the lever member and by the beam member which are cooperable for regulation of the spacing between the presser and heated cylinders.

Abstract: The invention relates to a sammier press, especially for leather and fur, with a pressure roll and counter-pressure rolls bearing thereon, whereof at least one is driven, and with two conveyor belts moved by frictional engagement which receive the material that is to be pressed between them, drawing it through the pressing zone formed between the pressure roll and the counterpressure rolls.

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.
