Abstract (en)
A selector for use in textile machines, in particular for forming hosiery and knitwork and comprising a series of needles (1) disposed peripherally on a rotary drum (2) or on a fixed bed and arranged, when selected, to intercept textile yarns in order to obtain an article with particular patterns and/or colours. The selector comprises a bimorphous piezoelectric cell (8) of known type clamped at one end (12) between support elements of insulating material and carrying at its free end an arm (17) operating on an oscillating cam (21) which, following the passage of current within said piezoelectric cell (8) and its consequent deflection, acts on said needles (1) to cause their selection and/or deselection and obtain the particular pattern and/or colour required on the finished fabric.
