METHOD OF COMPUTER-AIDED FOOTWEAR CUTTING Russian patent published in 2014 - IPC C14B5/00 

FIELD: process engineering.

SUBSTANCE: proposed method comprises fitting of leather on digitiser stage, digitisation of leather outline and defect sections, virtual lay-up of parts with allowance fro leather geometry and defects, transmission of IN/OUT instructions to blade drives and vibrating blade drive instructions and making the cutting jobs. Video sensor automatically performs levelling in thickness and bundling. Leather outline geometry, area and reference points in contact with locating points are defined. Obtained data is transmitted to central computer. At once, digital camera arranged nearby video sensor at coordinate device indentifies leather flaws and located them. Obtained data is also transmitted to central computer for it to relay instructions to industrial robot for distribution of parts among accumulation stackers. Working platforms have the drives to displace them on track composed of top and bottom runs. Top run extending rails are connected with lifting-and-lowering devices.

EFFECT: higher accuracy and efficiency.
