Abstract
A yarn carrier comprises a carrier base, a reciprocator, a feeder, and a movement converter. The reciprocator is supported on the carrier base to move in reciprocation with a traveling direction of the carrier base. An engaging surface is temporarily engageable with an accompanying member of a carrier accompanying device. The feeder, has a main-yarn feeding hole and a plating-yarn feeding hole, and supports at least one of the yarn feeding holes to freely rotate about an axis in a longitudinal direction of the feeder. The movement converter converts reciprocating movement of the reciprocator into rotation movement of the yarn feeding holes provided in the feeder, such that when the reciprocator is moved with its engaging surface engaged with the accompanying member, the yarn feeding holes can be rotationally displaced to change a positional relationship between the main-yarn feeding hole and the plating-yarn feeding hole.
