Abstract
A warp mending device draws a mending yarn unwound from a bobbin to a slot of a drop wire and a mail of a heddle corresponding to a trailing edge and a leading edge of a broken warp so that a loom is started. A positioning device is incorporated in the warp mending device for positioning drawing means relative to the mail of the heddle corresponding to the broken warp in a predetermined positional relationship therebetween when the warp is broken. The warp mending device includes: a yarn guide having a yarn guide line therein for guiding the mending yarn between the drop wire and the heddle corresponding to the broken warp; a nozzle for generating an air current inside the yarn guide line; a yarn leading device for drawing the mending yarn unwound from a bobbin into a slot of a drop wire or a mail of a heddle, whichever is located upstream of the drawing direction, and for leading the thus drawn mending yarn into an inlet of the yarn guide line. A positioning device is also provided for positioning the slot of the drop wire or the mail of the heddle, whichever is located downstream of the drawing direction relative to an outlet of the yarn guide line so as to confront the outlet.
