US 4,391,087 A · Twisting apparatus

Abstract

A twisting apparatus has a spindle extending along an upright axis, having an upper end and a rotatable lower end, and formed with a passage opening axially upwardly at the upper end and radially outwardly at the lower end. A bobbin support is rotatably carried on the spindle between the ends thereof and is provided with four angularly equispaced bobbin holders radially equispaced from the axis. Two of the diametrally opposite supports carry main bobbins and the other two carry reserve bobbins, with the leading ends of the yarns of the reserve bobbins being tied to the tail ends of the yarns of the main bobbins. The spindle is rotated about the axis while the bobbin support is held against rotation. The leading ends of the yarns of the main bobbins are led down through the passage and up around the bobbin support while the spindle is rotating to wind the yarns together and form a balloon around the support. The bobbins can be standard small-diameter bobbins such as come directly from a spinning machine.

A twisting apparatus comprising:

a spindle extending along an upright axis, having an upper end and a rotatable lower end, and formed with a passage opening axially upwardly at said upper end and radially outwardly at said lower end;
means for rotating said spindle about said axis;
a bobbin support rotatably carried on said spindle between said ends thereof and provided with a plurality of bobbin holders spaced about and radially offset from said axis and each adapted to support a respective bobbin carrying a respective yarn, whereby said yarns can be led down through said passage and up around said bobbin support while said spindle is rotating to wind said yarns together and form a balloon around said support;
and
means for preventing rotation of said support about said axis even while said spindle is rotating, said bobbin holders being angularly equispaced about and radially equispaced from said axis, said bobbin holders number four, including two for main bobbins and two for the reserve bobbins, the holders for said main bobbins being diametrally opposite each other and alternating with the holders for said reserve bobbins.
