Abstract
A dryer seal. The seal is formed from an elongate multi-layer structure having a strip of fibrous material folded upon itself to establish a folded perimeter edge and a pair of outwardly projecting portions projecting away from the folded perimeter edge. A fibrous interior spacer layer is located between the outwardly projecting portions and a single attachment seam extends at an inboard location substantially parallel to said folded perimeter edge.
Claims14
A dryer seal comprising an elongate multi-layer structure wherein said elongate multi-layer structure comprises a strip of fibrous material folded upon itself to establish a folded perimeter edge and a pair of outwardly projecting portions projecting away from said folded perimeter edge and a fibrous interior spacer layer disposed between the outwardly projecting portions and wherein a single attachment seam extends at an inboard location substantially parallel to said folded perimeter edge so as to adjoin said outwardly projecting portions to said interior spacer layer at a defined location inboard of said folded perimeter edge, said outwardly projecting portions defining legs extending away from said folded perimeter edge in substantially parallel relation to one another in adjacent relation to opposite sides of the fibrous interior spacer layer, said legs terminating at distal ends remote from the attachment seam, wherein said distal ends are adapted to flare outwardly away from the fibrous interior spacer layer, said legs comprising intermediate segments disposed between the attachment seam and the distal ends, said intermediate segments adapted to maintain contact with at least a portion of the fibrous interior spacer layer when said distal ends flare outwardly away from the fibrous interior spacer layer.
A dryer seat comprising an elongate multi-layer structure wherein said elongate multi-layer structure comprises a strip of fibrous material formed at least partially from a plurality of entangled wool fibers wherein said strip of fibrous material a folded upon itself to establish a folded perimeter edge and a pair of outwardly projecting portions projecting away from said folded perimeter edge;
- and
- a fibrous interior spacer layer of needle punched polyester disposed between the outwardly projecting portions and wherein a single attachment seam of chain stitch or lock stitch seam construction extends at an inboard location substantially parallel to said folded perimeter edge so as to form a single bulbous pocket holding a proximal edge of the fibrous interior spacer layer and adjoining said outwardly projecting portions to said interior spacer layer at a defined location inboard of said folded perimeter edge, said outwardly projecting portions defining legs extending away from said folded perimeter edge in substantially parallel relation to one another in adjacent relation to opposite sides of the fibrous interior spacer layer, said legs terminating at distal ends remote from the attachment seam, wherein said distal ends are adapted to flare outwardly away from the fibrous interior spacer layer, said legs comprising intermediate segments disposed between the attachment seam and the distal ends, said intermediate segments adapted to maintain contact with at least a portion of the fibrous interior spacer layer when said distal ends flare outwardly away from the fibrous interior spacer layer.
