Abstract: In a method for patterning a reel-to-reel strip in an automatic manufacturing process, a reel-to-reel strip is stuck onto a support plate having a low-tack adhesive. A laser beam is used to pattern the reel-to-reel strip. Carbon residues and/or cut pieces generated during a process of patterning the reel-to-reel strip are stuck on the support plate having the low-tack adhesive. Therefore, the carbon residues and/or the cut pieces will not fall down to other parts of the reel-to-reel strips during the automatic manufacturing process. Thus, it does not need to remove the carbon residues and/or the cut pieces from the reel-to-reel strips.

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.

Abstract: Dust plugs provide seals for openings in door frames and window frames to seal against air or water infiltration. The dust plugs are made continuously and automatically by feeding several weatherstrips having piles extending from rigid backing through a tool having side by side slots there through which extend from an anvil surface thereof. The backing strips rest on the surface in edge-to-edge relationship. An adhesive tape having a contact adhesive on one side thereof is fed synchronously with the pile weatherstripping in juxtaposition with the weatherstrips and in contact with the exposed sides of the backing strips. The dust plug material consists of the tape in contact with the weatherstrips and provides an assembly of the weatherstrips and the tape. Counter rotating puller belts engage dust plug material which may then be wound on a reel. For installation of the dust plug, the dust plug material is unwound from the reel and cut into dust plugs of desired length.

Abstract: The present invention is concerned with a method and apparatus for seaming together abutting side-by-side layers of planar material with adhesive and a backing tape to form a finished seam extending along the line of abutment. The method consists of laying a backing tape underneath the line of abutment between adjacent layers of planar material, such as floorcovering, followed by dispensing an adhesive along the edges of the abutting layers while simultaneously centering the backing tape with the line of abutment and dispensing adhesive on top of the backing tape. The edges of the abutting layers are then pressed together and against the backing tape until the adhesive has at least partially set thereby forming a finished seam.
