A roof drip molding having a resin layer of varying width on the surface of a supporting member having a varying width. The resin material is adhesively applied to the surface of the supporting member of varying width.

Molding having a resin layer of varying width applied to a supporting member of varying width

An apparatus for applying a resin layer of varying width to a surface portion of a supporting member having a varying width includes a stationary die in which is provided a cavity, a resin passage in the cavity, and an injector disposed at the outlet of the resin passage. An extruder extrudes resin material into the cavity via the resin passage. A sliding shutter mechanism is disposed in the cavity for varying the width-wise extent over which the resin is applied to the surface portion of the supporting member to permit application of a resin layer of varying width to the surface portion of the supporting member. A control unit is connected to the extruder and the shutter mechanism for controlling extrusion of the resin and the position of the shutter within the cavity. A method for applying a resin layer of varying width on the surface of a supporting member having a varying width involves advancing a supporting member in a feed direction into a stationary die, wherein the stationary die has a cavity, a resin passage in the cavity, and a movable shutter mechanism disposed in the cavity. Resin material is extruded into the cavity via the extrusion passage to apply a layer of resin material to the surface of the supporting member. During the extrusion of the resin material and the advancement of the supporting member through the stationary die, the shutter mechanism is moved to vary the width of the resin layer applied to the surface of the supporting member so that the supporting member exiting the stationary die has an applied resin layer of varying width.
