tie

(to tie) when a tie-down end is lifted and the pattern weft passes under it but over the other ends of the unit, it is 'tied' by the tie-down end to the top surface of the cloth. When the pattern weft passes over a tie-down end and under the other ends in the unit, it is tied by the tie-down end to the back of the cloth. In a single pattern pick, one tie-down warp end ties the weft to the top surface of the cloth in the pattern areas and a different tie-down warp end ties the weft to the back of the cloth in the background areas.
