Abstract

Device for quickly variable and high precision metering of powder, granulated or micropearl dyeing material including: a container (1) for the dyeing material that is put under vacuum by means of a suction tube (7) from the outside, a mesh-sieve (5) fixed on the base of the container (1), a scraper (2) rotating on the sieve (5) with changeable speed, a compass-type shutter, with changeable port, mounted under the sieve (5), a precision balance (20) below the shutter (6), an electronic computer (30) which can be programmed for checking and controlling the rotation speed of the scraper (2), the opening/closing of the shutter (6) and the weighing value of the balance (20).
