Abstract: A disk bearing a clamp for snagging the wire is supported by a bearing and attached by rods to a wire guard, the axial movements of which are controlled by a jack. The disk and guard are rotatingly driven via a pulley and a belt. Two driving mechanisms made up of couplings, driven pulleys, and driving pulleys make it possible to drive the guard and the disk via an auxiliary shaft either at a speed synchronized with that of the reel or at a slightly slower speed. The clamp then lags behind the reel and forms a loop with the leading end of the winding.

Abstract: A double winding machine for winding wire on reels includes two reel supports with drive shafts. Each support is equipped with a snagging mechanism comprising a hook-bearing disk with hook, an uncoiling member, and a bearing for supporting the disk and the uncoiling member coaxially with the reel and for allowing relative displacement of the disk and uncoiling member between an initial and a displaced position. A disengageable coupler is provided to rotationally couple the disk, uncoiling member and reel. The coupler can be translationally disengaged. Brakes are provided for the disk to produce a lag between the disk and reel to lengthen the leading end of the wire. The relative displacement is performed with the lag, allowing the leading end to be retained in the hook and uncoiling member. The leading end is thus made accessible, even after winding is complete.

Abstract: A textile machine having a line of bobbins to which filaments are fed continuously is provided with bobbin-exchanging device arranged to run along a rail in front of the bobbins. On reaching a bobbin holder on which a full bobbin is to be exchanged for an empty one, the device is stopped and a first arm is swivelled upwards for a holding device thereon to engage the full bobbin. Simultaneously a second arm carrying a power driven friction roller for maintaining the rotation of the full bobbin is swivelled into engagement with the full bobbin, and a third arm having an outwardly extended pivoted terminal portion carrying a device holding an empty bobbin, is swivelled upwards. The first arm is then withdrawn carrying the full bobbin past the empty bobbin while the full bobbin is being driven by the friction roller. The terminal portion of the third arm is pivoted inwards and the third arm raised further to place the empty bobbin in the bobbin holder.
