A carpet seaming iron of the kind used for making face seams with hot melt adhesive tapes forms a raised center bead in the molten adhesive produced behind the iron. The center bead is of a sufficient height and stiffness to coat the side edges of the carpet backings with hot melt adhesive as the undersides of the carpet backings are lowered onto the layer of molten adhesive. The side edges of the backings are locked directly together through the adhesive interposed between the side edges.

Non woven fabrics are made by a method and an apparatus in which a preformed, planar set of adhesive coated or impregnated fill strands having a fixed orientation, spacing and tension of the fill strands is laminated to warp strands in the nip of pressure rolls. Adhesive lines are printed on a side of the warp strands opposite that engaged by the fill strands to prevent warp strands from hanging loosely from that side of the fabric.

A manually operated carpet repair tool cuts a circular plug in a carpet to remove a damaged area. The carpet repair tool has two cutting blades which are equally spaced circumferentially on the lower periphery of the tool for balanced tracking of the blades in the cut. Circumferential grooves on a centering pin grip the carpet plug as the cut is being made so that the operator can test to see if the plug is free during the cutting operation and still continue the cut in exactly the same location as before if the cut has not been completed. A carpet repair disk is positioned beneath the opening cut in the carpet to retain a matching carpet repair patch in the opening cut by the carpet repair tool. The carpet repair disk includes a strand reinforced paper backing with an adhesive on the upper surface. The carpet repair disk is of larger diameter than the diameter of the opening cut in the carpet. The disk has a slit extending inwardly from the periphery into the center of the disk to form two flaps so that a larger size disk can be easily inserted in the smaller size opening by first placing one flap partially through the opening and into the carpet and then rotating the rest of the disk through the opening and into the backup position under the opening in the carpet. The adhesive on the upper surface of the disk engages the back side of the carpet entirely around the opening and also engages the back side of the patch to hold the patch into place.
