Abstract
A path for guiding bobbin holders (7, 8) is formed in a closed loop shape on a machine frame (1), inner gear members (65, 66) are spaced in an axial direction of the bobbin holders (7, 8) and disposed along the bobbin holders guiding path. Two bobbin holders (7, 8) are supported on sliders (13, 14), respectively, and gear wheels (67a, 67b, 68a, 68b, 69a, 69b, 70a, 70b) disposed at the support portions of the bobbin holders (7, 8) engage with the inner gear members (65, 66). Two endless chains (82, 83) are spaced in an axial direction of the bobbin holders (7, 8) and disposed along the bobbin holders guiding path. The chains (82, 83) are connected to the bobbin holders (7, 8), respectively, whereby the bobbin holders (7,8) can be independently moved along the bobbin holders guiding path formed to locate a winding position, a doffing position, an empty bobbin donning position, a stand by position and a bobbin changing position.
