摘要

Improvements in the object of the main patent no. 464,628, for improvements introduced in pigment product dispensers, applied to plastics extruder machines, said improvements being characterized by replacing the auger provided in the pigment pellet supplying hopper, by a flattened cylinder whose axis of rotation is also arranged in a horizontal direction, but in whose contour it shows, equidistantly distributed, a series of concavities that, acting as transporting spoons, pick up the pellet of pigment that descends through the aforementioned hopper and transfer in a perfectly dosed way, to a descending conduction that ends in a chamber communicated with the place occupied by the auger of the extruder, where, in the drink ratio, it comes into contact with the colorless pellet, moving the specified cylinder to be conveniently attached to an axis that, by means of convenient interposed transmissions, it is moved by the same extruder screw, or by an extension thereof, although it has to be specified that said pigment pellet supply cylinder can also be applied to a metering hopper disposed in a machine that in place to be extruder or plastic injection, moving, alternatively, said cylinder, in a pneumatic way, by the same pneumatic system of the fuel transfer.
