    摘要: An alternate twist plied yarn formed from a plurality of strands of singles yarn twisted in alternating directions in lengthwise intervals of first half-cycles of twist at a predetermined twist level followed by second half-cycles of twist at the same twist level with reversal nodes therebetween, the singles twisted yarns being ply-twisted together in alternating directions in lengthwise intervals of first half-cycles of ply-twist followed by second half-cycles of ply-twist, there being a bond formed adjacent each node wherein the first half-cycle of ply-twist is located within the bond and the second half-cycle of ply-twist originates at one end of the bond, the twist level in the singles twisted yarn is between 25% in the same direction and 60% in the opposite direction of the twist applied to the singles yarns before plying.

    摘要: An anchor connectable to a carpet stretching apparatus includes a generally L-shaped member in which a first leg defines a base while a second leg forms an upright backstop. The base has a forward edge and an underside thereon. A plurality of inclined gripping pins engageable with the carpet is disposed on the underside of the base. The gripping pins are inclined from the forward edge toward the backstop. The L-shaped member is engageable with a carpet stretching apparatus so that a force generated by the carpet stretching apparatus while stretching a carpet reacts against the backstop at a point of application substantially rearwardly of the gripping pins in the direction of inclination thereof.
