<p>The applicator consists of a tunnel (1) in the bottom of a tank (2) containing the adhesive material (3) and through which the strip (3) passes as it unrolls, picking up a coating of adhesive in the open section (20) of the tank. The outlet end of the tunnel has a regulator (13) to control the adhesive layer, equipped with a toothed edge to make grooves in the surface of the surface of the adhesive. The regulator is in the form of a wingnut (14) and spring.The tank can be supported by a wheeled trolley with telescopic legs which allow the tank to be set at a suitable working height. ADVANTAGE - Design simplicity, efficient in operation and relatively low cost.</p> |
