A carriage which is movable into a position over a loom carries a manipulator for drawing a replacement yarn through a reed. A tracing element moves across the width of the warp yarns at a point downstream of the reed to detect a gap in the warp yarns corresponding to the position of a broken yarn. The manipulator moves into alignment with the gap and a guide on the manipulator pivots through the reed to receive an end of the replacement warp yarn. Return pivoting of the guide pulls the replacement warp yarn through the reed and a yarn clamp is activated to faciliatate tieing in of the warp yarn during subsequent operation of the loom.
