  • Patent number: 6957554
    Abstract: The use of lime and sodium sulfide in leather making creates a lot of environmental concern. However, there is no commercial beam house process that could totally eliminate the use of lime and sodium sulfide. In this invention, a novel bio-chemical process has been standardized employing specific enzymes and non-toxic chemical that could totally eliminate the use of lime and sodium sulfide in leather processing. It has been found that the extent of hair removal and opening up of fiber bundles is comparable to that of the conventional limed leathers. Performance of the leathers is shown to be on par with conventionally leathers. The process also enjoys reduction in chemical oxygen demand and total solids load compared to conventional process.

  • Patent number: 5830238
    Abstract: Procedure to improve the area yield in the manufacture of leather consisting of a thermal treatment applied to the extended or stretched leather, before the operation of drying. During this treatment there should be no loss in the water content of the leather. The applicattion of this procedure in the manufacture of leather allows improvements to be obtained in the area yield of about ten percent and, when applied to dyed leathers, an improvement is obtained in the fixation of the products used in the wet phases and, therefore, an improvement in the fastness properties to rubbing at dry as well as wet conditions. The application of this procedure reduces the modulus of the leather for which its use can be especially interesting for leather destined for clothing, upholstery, and some types of footwear which require lower elasticity values.

  • Patent number: 4959977
    Abstract: A machine for progressively roughing marginal portions of shoe bottoms comprising a shoe support (18) having toe support means (470) and a heel support arrangement including two sets of clamps (390, 392), one set (392) of which serves also as sensing means for sensing, by engagement with an off-set portion of the shoe last whether the shoe thus supported is a left or a right. An inductance sensing device (610) associated with the second set of clamps (392) supplies a signal to control means of the machine, the signal being dependent upon whether the shoe is a left or a right. The control means ensures that, in the operation of the machine, a roughing operation is carried out on the shoe bottom in such a manner that the inside waist region of the shoe bottom is traversed always in the same directiion, regardless of whether the shoe is a left or a right (and of course similarly the outside waist region is consistently operated upon).

  • Patent number: 4450764
    Abstract: A frame forms a container having four vertical sides and a flat bottom plate. A hydraulically raised and lowered gate forms one of the sides. Wet hides are stacked on a pallet commonly used with a forklift. The gate is raised, and the loaded pallet placed on the bottom plate. The gate is lowered, and fillers are extended through side openings in the pallet into voids between the pallet top and bottom. A platen above the hides is hydraulically pressed downward within the container to compress the hides. A selected pressure on the hides is maintained for a desired compression period. The fillers within the voids limit deflections of the pallet top during compression of the hides, and consequently prevent damage to the pallet. The fillers are withdrawn, the gate raised, and the loaded pallet removed. The compressed, dry, cohesive hide bundles have a flat top and flat, vertical sides and are more efficiently packed for shipping.
