Abstract
A weft presenter for looms without shuttles comprises a plurality of weft presentation rods each of which is connected, by means of a kinematic chain, to the main shaft of the loom in such a way as to move with reciprocating motion in synchronism with the movement of the batten. Said kinematic chain consists of a shaft driven to rotate around its own axis with reciprocating motion, by means for driving said shaft which receive the motion from the loom, by a plurality of arms pivoted on said shaft in a freely oscillating manner and maintained in a raised position by means of respective spring means, and by a plurality of electromagnets integral with said shaft and each engageable, by excitation, with one of said arms relative to it to rotate it to a lowered position against the action of said spring means. Each arm is operatively connected with a respective weft introduction rod which is guided to translate with a reciprocating motion following the oscillation of the arm itself.
