<p>Bordered and custom fabricated rugs (11) are formed by initially bonding carpet segments (12, 15, 17) together along abutting edges (44, 45), using a high temperature hot melt adhesive (43). Preferably a latex coated material is then bonded to the backing of the adjoined carpet segments using a second, lower temperature hot melt adhesive (37). A reinforcing mesh layer (34) is preferably bonded to and between a rug backing (33) and the carpet backing (32). The apparatus used to bond the rug backing (33) to the carpet backing (32) includes two opposed endless belts which carry the assembly through a heating section then through a cooling section as pressure is applied. The heating section melts the low temperature adhesive (37), which then flows under pressure, but does not affect the high temperature hot adhesive (43). The seams of the resulting rugs are remarkably resistant to separation.</p> |
