Abstract
A process for breaking yarn during the automatic removal of bobbins from banks of spindles, permitting the operator to grip the end of the yarn at the base of the bobbin (1) and guaranteeing good retention of the yarn during handling of the bobbin (1), thereby avoiding premature unwinding. There is also provided a presser finger for practicing this process, comprising a blade (5) having upper and lower heels (6 and 7) respectively upwardly and downwardly inclined from the plane of the blade. The process comprises, at the end of winding, stopping winding at the lower portion of the bobbin (1), then forming a lower winding of several turns about the base of the bobbin (1) and specifically about the core of the bobbin, then rising and effecting a limited upper winding followed by a descent and breaking of the yarn below the upper portion of the bobbin (1). Specifically, the upper winding is of about one-half turn about the core above the yarn wound on the bobbin. The invention is in the field of the textile industry, particularly concerning banks of spindles for long fibers.
