Estimating the term…
Weatherstrips (13, 15) having opposed pile sealing elements (226) are installed in opposed slots in a frame member (14) so that the piles may engage opposite sides of a panel, shutter or screen (203), by insertion apparatus having laterally-movable slotted guides (60, 62). The weatherstrips are driven through the slots in the guides by a drive wheel (42). A laterally reciprocating cutter (48) has openings (107, 109), through which the weatherstrips are driven, and shearing edges (98) for cutting ends of the weatherstrips to facilitate entry of the weatherstrips from the slots in the guide into the slots in the frame member. Metering wheel (44) engages at least one of the weatherstrips moving through the guides, and provides for actuation of the cutter, when the desired length of the weatherstrips is driven through the guides; the length corresponding to the length of the frame member which receives the weatherstrips.
Apparatus for inserting dual weatherstrips having seals, extending toward each other on opposite sides of a channel in a frame to define a sealing path along opposite sides of which a closure member is engaged in sealing relationship by said seals, and with respect to which said frame said closure member is movable, said apparatus comprising a pair of guides in which said weatherstrips are movable with respect to a driving wheel which is engageable in driving relationship with said weatherstrips to drive said weatherstrips longitudinally of said guides for insertion of said weatherstrips into said channel of said frame when said frame is disposed in alignment with an output end of said guides, at least one of the said guides is mounted for lateral movement so that a lateral spacing of said guides corresponds to a spacing of said channel for receiving and having said weatherstrips inserted therein when driven by said driving wheel.
Apparatus for inserting a pair of weatherstrips having seals extending toward each other from backing strips on opposite sides of a channel in a frame along which a member, opposite sides of which are engaged in sealing relationship by said seals, and with respect to said frame, said member is movable, said apparatus comprising:
