ABSTRACT:
This invention relates to a weft mixer device for looms which comprises a plurality of selection fingers each one of which can occupy either an active position in which it supports a weft yarn in the path of a weft-inserting member or an inactive position in which it supports a yarn outside of said path. The selection fingers are mounted for oscillation on a common vertical shaft supported by the loom frame and are articulated on said shaft about an axis at right angles to the axis of said shaft. The selection fingers are guided between the bars of a grid which consists of a frame having two opposed sides of unequal length and in which are mounted movable bars which extend between said two opposed sides. The internal length of the shorter of said two opposed sides is substantially equal to the sum of the thicknesses of said bars and of the thickness of a single selector finger, and the internal length of the longer of said sides is at least equal to the sum of the thicknesses of all of said bars and all of said selection fingers.
