Abstract
Abstract Fibrous yarn shade card and method of making by placing yarns in side by side array on a synthetic resin backing and bonding by heat and pressure along a transverse heat sealing line which anchors the yarn fibre along the line. A plastic cover sheet may be bonded at the same time to provide a cover strip for the card.

The method of making a plurality of identical yarn shade cards each card providing an array of colored yarns adhered to a backing sheet comprising: a. placing a number of individual fibrous yarns in side-by-side array parallel to one another across and on a backing sheet which is composed of synthetic thermoplastic material which becomes adhesive in response to heat; b. applying heat and pressure simultaneously along a plurality of spaced apart, parallel bonding lines which extend the length of said sheet, said bonding lines extending transversely to said array of yarns and across the same, the heat melting the thermoplastic material to fuse into and to anchor the fibers of the yarn along each said line to the backing sheet; c. thereafter cooling the shade card so that the melted thermplastic material sets along said bonding lines to thereby form a plurality of arrays of yarns bonded along said lines and fused onto said backing sheet; and, d. cutting one yarn shade card from said plurality along a line which is parallel to said bonding lines and thereby produce a plurality of separated shade cards.
