To enable stable pattern coating without disorder even in disadvanta geous circumstances by constituting a discharge roller for discharging a hot melt adhesive supplied from a supply means from a pattern cylinder and a driving drum which is installed in the cylinder and leads the adhesive to a discharge opening.

A discharge roller 3 and a transfer roller 41 are rotated so that their circumferential speeds are equal to each other, and a hot melt adhesive which was charged in a tank and melted is supplied into the driving drum 32 of the roller 3 by a pump through the supply tube 21 of a supply means 2. The adhesive is supplied to a recession 32b formed in its peripheral part through a main pipeline 32a and a branch pipeline 32c and discharged in a prescribed pattern on the outer surface of the roller 41 through the discharge opening 31a of a pattern cylinder 31. Next, the adhesive is transferred in a prescribed pattern on the surface of a nonwoven fabric sheet S moving between the roller 41 and a nip roller 42.
