Dust plugs provide seals for openings in door frames and window frames to seal against air or water infiltration. The dust plugs are made continuously and automatically by feeding several weatherstrips having piles extending from rigid backing through a tool having side by side slots there through which extend from an anvil surface thereof. The backing strips rest on the surface in edge-to-edge relationship. An adhesive tape having a contact adhesive on one side thereof is fed synchronously with the pile weatherstripping in juxtaposition with the weatherstrips and in contact with the exposed sides of the backing strips. The dust plug material consists of the tape in contact with the weatherstrips and provides an assembly of the weatherstrips and the tape. Counter rotating puller belts engage dust plug material which may then be wound on a reel. For installation of the dust plug, the dust plug material is unwound from the reel and cut into dust plugs of desired length. Guides on upstream and downstream ends of the tool bring the tape into contacting relationship with the weatherstrips to provide the assembled dust plug material.
