Abstract A strip of tissue wrap paper of the same width and same length as a strip of hot melt carpet seaming tape is wound into the roll of tape in a manner such that when the tape is unrolled the tissue paper is unrolled with the tape and underneath the tape. Then when the tape is positioned on the carpet underlay pad ready for face seaming with the tissue paper beneath it, any melting of the pad (resulting from the heat produced in the face seaming operation) will cause the pad to stick to the tissue, rather than to the tape. During the stretching of the carpet, the seam is free to move over the pad and cannot cause wrinkling. The tissue paper may be lightly fastened to the back of the hot melt tape by dots of adhesive on the center line of the tape of about 1/8 -inch diameter at about 3-inch intervals to insure better registration of the hot melt tape and the tissue paper. After the tissue adheres to the surface of the pad during seaming, the hot melt tape readily breaks loose from the tissue during stretching of the carpet, effectively preventing wrinkling of the pad.
A method of face seaming carpet with a hot melt adhesive carpet seaming tape (of the kind having a barrier sheet, yarn reinforcement on the face side of the barrier sheet and a layer of hot melt adhesive on the face side of the barrier sheet) to prevent sticking of the tape and carpet to surfaces of plastic and rubber foam underlay pads which can be melted by the heat produced during the face seaming of the carpet with the tape, said method comprising, winding a strip of paper and a strip of the tape into a roll with the paper on the backside of the barrier sheet and with the paper aligned with the tape, raising abutting carpet edges from a top surface of an underlay pad composed of a material that melts and becomes sticky at temperatures near the melt temperature of the hot melt adhesive, unwinding the roll to dispense the tape face side up beneath the edges of the carpet to be seamed and simultaneously to position the paper beneath the tape between the underlay pad and the back face of the tape, heating the layer of hot melt adhesive, and pressing the edges of the carpet down on the heated hot melt adhesive to make a face seamed carpet and to cause any melted surface of the pad to stick to the paper rather than to the backside of the tape, so that the seamed carpet is free to move over the paper and the surface of the pad without wrinkling.

A method of face seaming carpet with a hot melt adhesive carpet seaming tape (of the kind having a barrier sheet, yarn reinforcement on the face side of the barrier sheet and a layer of hot melt adhesive on the face side of the barrier sheet) to prevent sticking of the tape and carpet to surfaces of plastic and rubber foam underlay pads which can be melted by the heat produced during the face seaming of the carpet with the tape, said method comprising, winding a strip of paper and a strip of the tape into a roll with the paper on the backside of the barrier sheet and with the paper aligned with the tape, raising abutting carpet edges from a top surface of an underlay pad composed of a material that melts and becomes sticky at temperatures near the melt temperature of the hot melt adhesive, unwinding the roll to dispense the tape face side up beneath the edges of the carpet to be seamed and simultaneously to position the paper beneath the tape between the underlay pad and the back face of the tape, heating the layer of hot melt adhesive, and pressing the edges of the carpet down on the heated hot melt adhesive to make a face seamed carpet and to cause any melted surface of the pad to stick to the paper rather than to the backside of the tape, so that the seamed carpet is free to move over the paper and the surface of the pad without wrinkling.
Claim 3
Dependent Claim
48 words
A method as defined in claim 1 including connecting the paper to the backside of the barrier sheet by a series of widely spaced adhesive connections of small area which are readily breakable in the event of any shifting of the carpet with respect to the underlay pad.
Claim 4
Dependent Claim
35 words
A methoD as defined in claim 1 wherein the paper extends across the entire width of the barrier sheet and is wound into the roll without any connection between the paper and the barrier sheet.
