Abstract
An improved bobbin holder utilized for each winding unit of a textile machine such as an open-end spinning frame or an automatic winder. To eliminate the undesirable influence caused by the possible shock or vibration imparted to the cradle arms of the bobbin holder during the yarn package forming operation, a damping device is disposed at a position between one of the cradle arms and a stationary part of the machine frame in such condition that a free end portion of the damper is connected to the cradle arm at least during the normal operation for forming a yarn package, and a mechanism for releasing the damping operation by the damping device is provided in the bobbin holder.
