Abstract: A dermatome (10) comprising at least two oscillating blades (20a-d) arranged parallel to each other and configured to simultaneously cut separate skin grafts (2a-d) at different depths from a donor site (1).

Abstract: Provided are a car-seat split crust leather and leather. A hide already subjected to pretreatment and subjected to tanning treatment is split into leather including a grain surface and into split leather with a thickness of 4 mm to 2.3 mm, the taken-out split leather is arranged so that a flesh side of the split leather can be located on an upper side and that a grain side of the split leather can be located on a lower side, split leather with a thickness of 2.6 mm to 1.8 mm is made, next, the flesh side of the split leather is shaved to thereby set the thickness of the split leather to 2.0 mm to 1.1 mm, and a car-seat split crust leather with a thickness of 1.6 mm to 1.0 mm is manufactured, which is then subjected to tanning and re-tanning treatment, and has a coating film formed thereon.

Abstract: A process used to cut and model sheets of leather or other modellable materials, according to which cutting and modeling are carried out by means of a die and a lid-punch that cooperate to cut a leather sheet positioned and tightened between the die and the lid-punch according to predefined cutting lines and at the same time model the sheet in a stable way by a plastic film injected on one of the two sides of the sheet.

Abstract: A ring roller, used in the hide splitting process as a hide transport device, is described that is continuously self cleaning and which provides a constant gap between outer rings of a ring roller. The ring roller is capable of directing pressurized water, or other gaseous and/or liquid fluid from the internal to the external surface of the ring roller. The constant supply of pressurized water, or other gaseous and/or liquid fluid from the internal to the external surface of the ring roller prevents the entry of lime solution, flesh, fat, grease, and other materials that result from the hide splitting process, into the ring roller. Therefore, the ring roller constantly and continuously provides optimum, consistent, high quality performance. Maintenance downtime for the ring roller is minimized. The ring roller, properly operated, will perform to expected design and operational parameters.
