A multi-port applicator for supplying bonding and sealing material(s), for instance to elongated channels and/or recesses, and to members for fitting within channels. The applicator comprises at least two heatable heads in tandem, the trailing head having an orifice arranged for depositing molten thermoplastic on the same or other adhesive material supplied by a preceding or leading head orifice. Opposite sides of the heads are of configuration complemental to the walls defining the space to be filled, for example the peripheral channel of a double glazed unit. The trailing head may include a smoothing follower to shape the deposited material while it is still soft and insure a substantially uniform depth of total deposit.

An applicator for flowing hot melt materials in superposed relation to the channeled periphery of a double glazing unit comprising panes of glass separated by a spacer having an outer surface located inwardly of the edges of said panes, said applicator having opposite sides spaced and formed for sliding fit with the marginal surfaces of the panes, a leading portion of the applicator being provided with a flat face for slidably engaging said outer surface of the spacer, a pair of orifices respectively opening through said flat face progressively to force hot melt into recesses extending longitudinally of the channel one at each side of said longitudinally and a trailing portion of the applicator having an orifice spaced from the outer surface of the spacer for extruding hot melt on the material deposited from said pair of orifices.
