Claim 3
Dependent Claim
75 words
APPARATUS FOR FEEDING A CABLE-LIKE ELEMENT COMPRISING ROTATABLE GUIDE MEANS CONSTRAINING SAID ELEMENT TO FOLLOW A PATH INCLUDING AN AXIAL INPUT END PORTION FOLLOWED BY A RADIALLY DIVERGING PORTION AND AN OUTPUT END PORTION COAXIALLY ALIGNED WITH AND SPACED FROM SAID INPUT END PORTION AND EXTENDING IN THE SAME DIRECTION, SAID ELEMENT BEING UNCONSTRAINED OVER AN INTERMEDIATE PORTION OF SAID PATH BETWEEN SAID DIVERGING PORTION AND SAID OUTPUT END PORTION, MEANS FOR ROTATING THE GUIDE
