A measuring device for measuring stickiness, imperfections and impurities in textile fibers, such a device includes a housing inside which a pair of rollers are placed, arranged side by side to one another and rotating in opposite senses and between which a web of cotton fibers is made to pass. The rollers are heated, the sticky fractions of the web that adhere to the rollers after the passage of the web between them are detected, and the sticky fractions adhering to the rollers are removed, wherein the heating is controlled by a processing and control unit as a function of the temperature of the rollers detected by a temperature sensor associated with them.

Measuring device for measuring the stickiness, imperfections and impurities of textile fibers, in particular cotton fibers

A measuring device for measuring the fineness and maturity of cotton fibers is provided. The measuring device includes a measuring chamber; a supply conduit; a flow regulator arranged along the supply conduit; a first pressure sensor upstream of the flow regulator; a second pressure sensor downstream of the flow regulator; an electronic proportional pressure regulator for regulating the air pressure in the supply conduit; and an electronic processing and control unit programmed to control the electronic proportional pressure regulator as a function of the detections of the first sensor and of the second sensor or of the second sensor alternatively and respectively to keep the difference between the air pressure upstream and downstream of the flow regulator or the air pressure entering the measuring chamber substantially constant and equal to a predeterminable value.
