ABSTRACT:
A device for depositing an adhesive substance at one or more predetermined points on wrapping material comprises rotating transfer or applicator disks with irregular profiles including areas destined for transferring the adhesive substance from a tank directly to a corresponding number of predetermined points on the wrapping material. A pair of wiper disks wipe adhesive substance from the two sides of each transfer disk ahead of the position where the adhesive substance is deposited. A dosing collar is interposed between every two wiper disks for dosing and rendering uniform in thickness the adhesive substance on the areas destined to transfer the adhesive substance. The wiper disks and dosing collars are given, in the interaction area with the transfer disks, a movement in a direction opposite to that of the transfer disks.
