摘要:
Weatherstripping is inserted in an extrusion on-line with an extruder (18) which provides the extrusion (14) as it moves towards a station (28). The extrusion at such station is pulled and cut into sections (10) from which frames of windows are fabricated by fabricators, thereby avoiding the need for insertion of the weatherstrip into the sections offline by the window fabricator. The insertion apparatus includes rollers (46,48) and an insertion wheel (44) which inserts the weatherstrip (21) into a slot on one side of the extrusion. Rotation of the rollers is coupled to the insertion wheel by a transmission so that the weatherstripping is driven at the same or greater lineal speed than the speed at which the extrusion moves towards the pulling and cutting station (28), thereby assuring that the weatherstrip (24) reaches the cutter in the cutting station simultaneously with or ahead of the extrusion (14) at the cutter and is not pulled back, which would be the case if the insertion wheel (44) was not rotationally coupled to the rollers (46,48) and moved at a slower speed than the extrusion due (14) to friction which retards the rotation of the wheel. The sections are filled with weatherstripping along their entire length to facilitate the use thereof by the fabricator in providing components of the frames of the windows being fabricated.
摘要:
A weatherstrip for use with a T-slot. The weatherstrip includes a sealing element, such as a pile of yarn, on one side thereof and a bead on the opposite side thereof. The bead includes a curved surface for engaging an interior surface of the T-slot. Preferably, the bead is a material which adheres to the weatherstrip and comprises a hot melt glue such as ethylene vinyl acetate.

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.

A cushioning member is located between each support frame and the corresponding side of the shutter. The cushioning member (20) includes a pair of belt-shaped base members (21) and pile yarns (22) bridging between the base members (21). Some of the pile yarns (22) are cut at an intermediate portion (23) between the base members (21), which forms opposing first and second cut pile yarns with a cut in between. One of the base members (20) is attached to each support frame, and the other base member (20) contacts the shutter. The cut (23) permits the cushioning member to flexibly respond to movements of the shutter and satisfactorily exerts a cushioning function to suppress swaying of the shutter.
摘要:
Pile articles (20,22), especially pile weatherstripping, and a method and apparatus (10) for making such articles where the backing (24) and the pile (26) are of unlike material, especially nylon yarn for the pile (26) and polypropylene containing material for the backing (24), wherein prior to the welding of the pile (26) to the backing (24) the pile is first pre-heated using ultrasonic energy to melt the pile in a region (65) thereof where the pile is ultrasonically welded to the backing and before the weld is made. The ultrasonic melting occurs upstream of the location where the pile (26) is welded to the backing (24) so that the ultrasonically pre-heated melted region (65) of the pile (26) can cool and become at least partially solidified. Then pile (26) at the pre-heated melted region (65) is welded to the backing (24) and causes a reactive or chemical weld to occur, thereby attaching the pile (26) to the backing (24).

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.

Articles (12) made by winding of filamentary material (11), such as yarn and thread, are especially suitable for providing brushes and pile weatherstripping. In order to enable the yarn (11) to be unwound and payed out of spools (24) disposed in a stationary or static array, the yarn is fed from the spools (24) through a rotating spindle (30). A frame (14) located at the beginning of the path and may be provided by laterally spaced pairs of wire (52) which travel around posts (36) provided by rollers on a stationary bracket (38). In order to support the bracket (38) and the frame (14), a shaft (28) reciprocates a pair of support rods (100, 102) in synchronism with the rotation of the spindle (30). Bindings (60, 62) are applied to the ends of the loops (54) as they leave the winding station (14). Slitters (20) divide the loops (54).
摘要:
Pile weatherstripping, which is clad with a wrapping of a film (14, 25, 104, 216) of flexible material, has one or more rows (19, 27, 100, 102, 212, 214) of pile (10, 24, 105, 233) on a backing (12, 28, 106, 218) in side-by-side relationship. The wrapping film material conforms to the outside surface of the row (19, 27, 100, 102, 214) of pile so as to define a bulb or bulbs which are completely filled with pile. Single row (19, 27) pile weatherstripping is made by wrapping the pile (10, 24) with the film material (14, 25) after first ultrasonically welding the film material along one edge thereof to the backing (12, 28) under the pile. Then, the film material (14, 25) may be bent around the pile as it moves through a guide (88). The film material (14, 25) is then attached along the opposite edge to the backing thereof so as to completely enclose and clad the row (19, 27) of weatherstripping. The film material may be wrapped around one row (214) of two adjacent rows (212, 214) of pile (233) and attached to the backing (218), leaving the other row (212) unclad. The film material (104) may be wrapped separately around adjacent rows and attached to the backing (106) to provide two clad rows (100, 102) of weatherstripping. By selection of the porosity of the film material (14, 25, 104, 216) and the density of the pile (10, 24, 105, 233), weatherstripping having desired compressibility and air and water infiltration control properties may be produced.
