<p>A process for making a bonded carpet substrate comprising a thermoplastic material into which there is bonded a plurality of textile yarns, said process comprising: (a) forming two adhesive layers and positioning said layers in spaced face to face relation; (b) feeding a plurality of separated textile yarns between the said adhesive layers in zig-zag manner such that each of the yarns are bonded at intermediate points along the length of each respective yarn successively to both of the adhesive layers; (c) thereafter curing the adhesive layers to form a composite structure of cured adhesive layers on either side of a sandwiched layer of yarns; and (d) separating the composite structure into two separate carpet layers by cutting through the sandwiched layer of yarns; wherein the tension of each respective yarn is controlled so that the tension of each such yarn is substantially the same at the point of introduction between the said adhesive layers.</p> |
