Abstract
A method of applying a band of liquid adhesive in which the adhesive is spread by a resiliently flexible tapering applicator portion having an adhesive-guiding surface which extends to a narrow terminal spreading surface, the adhesive-guiding being concave about an axis which extends transversely of the spreading surface. The spreading surface is brought into contact with a workpiece, a pool of adhesive from an orifice in the adhesive-guiding surface is formed against the spreading surface, the applicator portion is caused to flex so that a portion of the adhesive-guiding surface extends along the workpiece surface, and relative movement between the workpiece and the applicator portion is brought about so that the adhesive is spread. An applicator head and an apparatus are also claimed.
