Abstract: A solid dispersion of pigment in granular form may include: at least one pigment; and at least one cold-water-soluble modified starch. A method for preparing an aqueous composition including at least one pigment may include: combining the at least one pigment, at least one cold-water-soluble modified starch, and water. A process for preparing a solid dispersion of pigment in granular form may include: mixing at least one pigment, at least one cold-water-soluble modified starch, and water to form a paste; and/or grinding the paste and evaporating at least part of the water to obtain the solid dispersion. A process for using at least one cold-water-soluble modified starch may include: preparing a solid dispersion of pigment in granular form by combining at least one pigment, the at least one cold-water-soluble modified starch, and water; and/or using the at least one cold-water-soluble modified starch as a carrier agent in the solid dispersion.

Abstract: A device for the automatic regulation of the quantity of adhesive deposited in flexible film rolling machines (20). These machines (20) include a coating column (21) and a bonding column (22), joined to each other by an upper frame (23); the premixed adhesive is loaded in a container (32), which is provided in a space formed between two adjacent cylinders (13, 14) and carried by the motion of two intermediate cylinders (13, 12) to a cylinder (15) designed to drag along the film (31). In this device, the adhesive is fed in a continuous manner from an automatic mixer (40), so as to vary the quantity dispensed per unit time depending on the basic pre-established weight and on the instantaneous speed of the rolling machine, the speed of the intermediate cylinders (12, 13) is varied automatically to increase or decrease the volume of adhesive laid down on the film (31).
