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. One of the components of the direction that the drive mechanism travels in is at an angle that ensures that the distributing eye will return from the vicinity of the standard winding to the vicinity of the thread reserve axially displaced thereto.
