Abstract: 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.

Abstract: A method of joining two flexible webs comprises bringing the webs into overlapping relationship, cutting the overlapped webs, removing a part of one or both webs from the region of the cut, and applying a length of adhesive material to marginal portions of the webs adjacent the cut.The webs may be held stationary while being joined. The cutting and joining are preferably effected simultaneously. The webs may be brought into register before cutting and joining. Adhesive material may be applied to both sides of the webs. Joining may be initiated manually or automatically in response to the speed or diameter of an expiring reel.

Abstract: Winding apparatus for continuously winding tape media upon reels contained within closed cartridges.
