Abstract (en)
[origin: US4843809A] In a spinning machine of the type having plural spinning stations each including a drafting system, a bobbin spindle and a coaxial funnel, the automatic exchange of empty bobbin tubes for fully wound bobbin tubes on the spindles is accomplished by interrupting the spinning operation without yarn breakage or severing, separating the spindles and funnels axially and radially from one another, removing the fully wound bobbin tubes and placing empty bobbin tubes on the spindles, engaging the still unbroken yarns with the empty bobbin tubes, then severing the yarns between the removed fully wound bobbin tubes and the replacement empty tubes, and repositioning the funnels and spindles and resuming spinning operation.
