Abstract
Block seals of pile weatherstripping (6), which may be inserted in doorjambs or window sash and are sometimes called dust plugs (15), are provided by hinged segments (16-21) of a continuous length of pile weatherstripping folded against each other. The pile may have an infiltration barrier providing a fin (4) which extends along a continuous serpentine path having loops (8) bridging the hinges (3). The hinged sections are connected by an adhesive-backed sheet (5). The block seals are adapted to be manufactured by a continuous process where the backing or base strip (7) of a continuous length of pile weatherstripping (1) is slit or notched from opposite spaced edges, leaving sufficient material in the backing to provide the hinges (3). The continuous serpentine barrier fin (4) allows the dust plug (15) to be installed oriented either with the ends or sides of the pile facing the moving member of the door or window to be sealed, while maintaining the fin infiltration barrier.
