APPARATUS FOR NON-DESTRUCTIVE EVALUATION OF FUR HAIR THICKNESS Russian patent published in 2003 - IPC

FIELD: fur and sewing industry and agriculture. SUBSTANCE: apparatus has clamp for separating vertical hair bundle, support for retaining hair bundle in position perpendicular to direction of action, unit for acting upon hair bundle, units for regulating value of action upon hair bundle and receiving action signal, and measuring unit. Unit for acting upon hair bundle clamped by means of clamp has two pointed probes with lower edge arranged at the level below lower outer surface of casing. Probes are rigidly fixed on slides positioned for reciprocation to one another. Cam is positioned between slides and fixed with one end on pin extending from casing of apparatus and terminating with handle mounted for rotation through 90 deg and fixed with other end in support for retaining hair bundle in said position. Support is made in the form plate located on casing base provided with two vertical side columns. Unit for regulating value of action is located in columns in single plane with cam axis and is made in the form of two compression springs and adjusting screws. Signal receiving unit is formed as rod positioned for contacting with slide outer wall. Apparatus may be used for determining hair thickness of natural and artificial fur. EFFECT: increased efficiency by optimized fur sorting and wider range of investigation of natural and artificial fur. 2 cl, 6 dwg, 2 tbl
