ABSTRACT:
A tufting machine has a needle mounting construction including a multiplicity of needle support carriages, each carriage being slidably mounted in guides for controlled movement in a direction normal to the path of reciprocation of the tufting machine push rods. Pneumatic cylinders are operatively connected with each carriage to effect movement in accordance with a predetermined pattern. A pair of needle holders are mounted within each carriage, each holder supporting a needle. The holders have slots for coupling onto a detent reciprocating with the push rods. The carriage may be moved so that one or the other or neither needle holder is coupled to the reciprocating push rods. When a needle holder is coupled, the needle attached thereto reciprocates and may cooperate with a hook to form pile. Each needle of a pair may be threaded with different type yarn so that unique patterning affects may be obtained.
