Abstract

A loop-taker mechanism with a rotating hook member (1) and a bobbin case (5) and a bobbin case bracket (9) has the property that the fissure (15) between the bracket and the bobbin case is not closed due to mass forces and frictions, when the upper thread loop (10) shall pass through the fissure. This one is kept open by mens of a magnet (17, 18) on each one of the bobbin case and the bracket, equal poles of the magnets facing each other.
