Abstract:
A device for the automatic regulation of quantities of adhesive deposited in a flexible film rolling machine (20), wherein said rolling machine (20) includes a coating column (21) and a bonding claim (22), joined to each other by an upper frame (23), and wherein a quantity of premixed adhesive is charged to a container (32) generally formed by a space formed between two cylinders set side by side (13, 14) and transported by the motion of one of said adjacent cylinders (13) to a film (31) dragging cylinder (15), wherein said adhesive is fed continuously from an automatic mixer (40), capable of varying the quantities fed per unit time depending on pre-established basic weights, and on said rolling machine's (20) instantaneous speed, said adjacent cylinders (12, 13) having a speed which is automatically varied so as to increase or decrease the quantity of adhesive deposited on said film (31).
