Abstract
The selector has a lower extension for retention by a fixed magnetic selection ring associated with a needle cylinder, and an upper shaped elastic portion for returning the lower portion of the selector towards the outside of a needle cylinder. A flat or inclined profile is defined uppermost on the selector for engagement with a correspondingly flat or inclined base of a sub-needle. A guide portion, having a longitudinal extension lying substantially parallel to the shaped elastic portion, is connected to the shaped elastic portion and is engageable with helical springs used for retaining selectors in needle cylinder grooves. The selector has an upper heel protruding therefrom at an opposite side with respect to said guide portion, and a lower heel extending parallel to the upper heel for engagement with a lifting cam.
