Abstract
A flexible, permeable seaming tape is treated by saturating one side with a liquid adhesive, which is allowed to dry so that the adhesive becomes inactive or non-tacky, thereby enabling the coated tape to be easily handled, coiled, etc. To seam together two carpet sections a strip of the tape is placed on a surface adhesive-side-up. The undersides of the sections adjacent the edges to be joined are coated with a liquid adhesive similar to that applied to the tape, and while still tacky, are urged downwardly against the tape with their edges in abutting relation. The still-damp adhesive on the carpet dissolves or reactivates the dry adhesive in the tape to form, when dried, a strong cohesive bond between the tape and carpet. The tape may comprise a single layer of non-woven material, or a non-woven material secured to a fiber matrix which resists lateral stretching.
