  • Device for constructing a thread reserve wound parallel onto a bobbin in a winder
    Patent number: 5104051
    Abstract: A device for constructing a thread reserve (6) wound parallel onto a bobbin (5 or 7) in a winder. The thread reserve is axially displaced in relation to the standard winding (4). The device has a reserve shackle (22) with two sections (24 & 25) that extend over the total width of the standard winding and slope together at an angle to the axis of the bobbin and toward a transition. The reserve shackle is moved back and forth by a drive mechanism in a motion that comprises one component perpendicular to the axis of the bobbin and another paralleling it. The reserve shackle has a distributing eye (23) at the transition between the sloping sections. A joint drive mechanism (27) travels back and forth at an angle to the axis of the bobbin to produce both components simultaneously.
