Reiling Method of "Rubber Lock" Face Seaming. When tape seaming two pieces of carpet together, be sure to treat the edges first with a sealer to prevent raveling, once the selvage has been removed. Then lay the pieces on the workroom floor (or the customer's floor at the site)face up. with each edge resting on the red center line of the seam tape which has previously been placed on the floor the entire length of the seam.

Reiling Rubber Lock adhesive is then applied to the back of each edge, and to the tape itself, with a special applicator, brushing it in and off so that it is buried in the material rather then resting on it. Only a small amount of adhesive is necessary. However, '"face seam paper" should first be laid on the floor under the tape to prevent adhesion of the seam to the floor.
A big advantage of this method for seaming is that pattern matching is vastly easier, since the carpet mechanic can see the entire pattern of any carpet throughout the seaming operation, and can thus control it better.
Rug-Sealz Seaming Method. U.S. Rubber Company's Naugatuck Chemical Division manufactures "Kwik-Grip" tape, which contains built-in grippers that hold the two edges of carpet together until the adhesive sets. This method also allows seams to be made from the top or face side, and can be used on conventional-backed carpet as well as rubber or plastic backed materials. The only difference in method is that for the latter, the "'Rug-Sealz" adhesive is allowed to become tacky prior to seaming.
