ABSTRACT:
In shuttless textile looms, the reciprocating motion of the weft needle is obtained directly from the oscillation of the sley, without requiring auxiliary transmission units. The sley is connected to a mobile element at the end of which is disposed the weft needle, by means of an oscillating plate, in which a shaped cam is formed. The cam may have an outer working contour or an internal working contour. The reciprocating movement is of adjustable amplitude.
