PURPOSE: To unweave simultaneously plural singles ends without using unweaving devices whose number is in accordance with the number of singles, on the occasion of splicing twins being done, by providing a plurality of more than four end introduction members in opposition to rotating unweaving members.

CONSTITUTION: This invention device 1 supports a rotor 3 within a casing 2. The center of the rotor which is supported at the upper part of a tubular base portion 6, is made to be a funnel shape having an air circulation chamber 7, and a beat plate V and combs 9 which act as unweaving members, are provided at the slope of the funnel shape. Also, a tubular shutter 19 is slidably inserted into the tubular base portion of the rotor. The lower end of the tubular shutter is connected to a suction source. The suction source, the shutter, the air circulation chamber, a clearance 15 and thread insertion holes 25 provided at a cover 11, constitute a series of air circulation passages. These thread insertion holes are provided at the perimeter edge of the cover whose holes are open toward the upper portion of the edge of the rotor, and operate as end introduction members 25 which guide ends toward the unweaving members 4 of the rotor. In the case of twins being undone, these are provided at 4 places at intervals of 90 degrees. Ends unweaved are drawn out and splicing is done.
