Conical bobbin winder reciprocating yarn guide

摘要

The reciprocating yarn guide mechanism has two rotors rotating in opposite directions. Two blades are at each rotor with radial movement in relation to the rotor, to move the yarn alternately over a straight guide where the gap between the straight guide and the rotor axes is shifted together with the radius where the yarn passes over the blade at the straight guide for an increase/decrease as the wound bobbin builds up to increase/decrease of the stroke length of the reciprocating movement. Each blade (8,9) is moved along a curved guide (15), coaxial to the rotor (4,5) and to one side, through the blade carrier (16). The curved guide (15) is rotated in relation to the rotor (4,5) by a cam disc (13) rotating with it.
