ABSTRACT:
Sealing means for sealing between a moving member and a fixed frame with which the moving member cooperates, said sealing means comprising rigid, elongated, channel means (on either the frame or the moving member), said channel having a back wall and at least one side wall; a rope which is resiliently compressible across its width positioned lengthwise in said channel; and an elongated metal strip having opposing front and rear surfaces, said strip being flexibly attached along the first of its two long edges to a side wall of the channel so as to sandwich the rope between the back wall of the channel and the rear surface of the metal strip, the channel means, rope, and metal strip being positioned such that the complementary part (either the moving member or the frame) can press against the front surface of the metal strip in sealing engagement therewith, urging the strip against the rope, the resilience of the rope providing a pressure counter to that exerted by the complementary part.
