Claim 7
Dependent Claim
71 words
The system as clained in claim 1, wherein said spinning bobbin feed station further includes a tray arrival sensor and a bobbin sensor for detecting the presence or absence of a bobbin on the tray and having a means for emitting a spinning bobbin request signal to the spinning frame side and receiving a spinning bobbin from the spinning frame upon detection of the absence of a bobbin on the tray.
Claim 8
Dependent Claim
48 words
The system as claimed in claim 1, wherein said bobbin draw-out station further includes a device having a vertically movable chucker whereby the bobbin on the tray is drawn out, and a device for discriminating and distributing an empty bobbin and a bobbin with extrememly slight residual yarn.
Claim 9
Dependent Claim
46 words
