Determination of rational parameters of a device for leather feeding to the machining area

The quality of mechanical processing the skin largely depends on parameters feeding to zone between working rolls. processed material at entrance must be free folds and wrinkles, i.e. one layer should enter Therefore, input into rolls is ensured with a rational selection profile guiding device for zone. A mathematical model was developed that allows authors determine leather area rollers, considering modulus elasticity density being processed. graphical solution made by numerical method, in order prevent saturated liquid from sticking surface, friction coefficient replaced rolling coefficient, rollers were placed certain angle level out smoothly feed it area. new design roller technological machines manufactured laboratory settings. machine equipped using possibility rotation around its axis. can several rows staggered arrangement. device, due installation relative direction feed, makes possible transport treated while eliminating longitudinal transverse folds. elimination wrinkles contributed an increase usable samples. Experimental testing work conducted squeezing samples device. width 1500 mm, diameter 30 allowed straightening moving gripping rollers. In experimental study, second-order D-optimal planning method used Kano matrix.
