ABSTRACT:
A small portable drawing-in machine is disclosed for suspension on the top of a loom reed and for movement along the lengths of the reed. A drive screw on the machine meshes with the reed dents to control the position of the machine on the reed, and a threading hook is projectable through the spaces between reed dents to draw warp yarns therethrough. A set of drive screws of different pitches may be replaceably mounted in the machine to give the machine a capability for use on reeds of different pitch.
The threading hook is reciprocably mounted on a rotatable turntable that is coupled through suitable gearing to the drive for the drive screw so that a machine cycle includes a movement of the threading hook to carry a warp yarn through a space between reed dents, a rotary movement through 360.degree. of the turntable to disengage the warp yarn from the hook, continues with a rotary movement of the drive screw sufficient to advance the drawing-in machine one step along the reed, and ends with a movement of the hook in the opposite direction through an adjacent space between reed dents to position it for receiving another warp thread.
