Title: Leather softening and milling - includes using paired rotating shafts with eccentric discs for leather moving between them
Inventor: KLOFT EDGAR
IPC: C14B1/40
Filed: 1991-11-18
Abstract: To soften and crumple and/or mill leathers or hides and the like, the material is fed between rotating shafts with raised and recessed sections as eccentric discs. They apply a milling or milled graining to the material. The rotating shafts have a tumble projection and recess structure through disc-type assemblies, with leather carrying elastic belts arranged to pass alternately round the shafts to give a number of milling points. The milling shafts are in pairs at each milling point, rotating against each other in synchronisation, while the gap between the two rotating eccentric or tumble eccentric discs remains constant. The milling effect is applied when the gap between the raised sections of the discs is at its narrowest to move the points (P1,P2) to and fro in relation to the direction of leather travel. The leather material follows this movement directly or indirectly through the applied friction. ADVANTAGE - The method allows small quantities to be processed with effective softening and surface appearance, even at the edges of small leather sections, for immediate use.
