Circular weft knitting machine.
A circular weft knitting machine for carrying out the knitting of variegated articles includes means for effecting selective, controlled two dimensional displacement of compound needle members (84) and associated sinker elements (474) so as to provide each such needle member with the selectable capability of performing a knit, tuck or float operation at each yarn feed location independent of the direction of knitting needle approach thereto. Also included therein are improved constructions for terry instruments (248), as well as the provision of unbroken continuous cam tracks in respective inner and outer fixed cam track sleeves (78, 86) for effecting such controlled two dimensional displacement of yarn engaging knitting elements in a path that is symmetric intermediate each adjacent pair of yarn feed locations and also is symmetric with respect to the midlocation therebetween.
