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 The first arm is then withdrawn carrying the full bobbin past the empty bobbin while the full bobbin is being driven by the friction roller.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. Means are provided on the device for opening and closing the bobbin holder to enable the exchange to take place. The bobbin holder is spring loaded to keep the bobbin, while being filled, in contact with a driving cylinder. The exchange operation may be initiated by a control device and carried through by programmed pneumatic actuating means.
