Abstract
A yarn-twisting apparatus comprises a spindle receiving the supply spool or bobbin, a rotating can or sleeve surrounding the spool and the bobbin, a yarn takeup arrangement for drawing the yarn from the upper end of the can, and a housing surrounding the can. According to the invention, the stationary housing and the upper and lower ends of the spindle are provided with closures which reach close to the spindle at the bottom and form an opening traversed by the yarn at the top. Means is provided for enabling the upper closure to be removed or displaced for ready access to the interior of the housing. The system reduces the power consumption required for twisting the yarn.
Claims17
A device for twisting a yarn, comprising:
- a spindle adapted to receive a supply spool of a yarn to be twisted and rotatable about an axis;
- means for rotating said spindle about said axis;
- a can surrounding said spindle and a spool adapted to be carried thereby and coupled with said spindle for rotation therewith about said axis;
- a stationary housing closely surrounding said can;
- and
- a closure member on at least one axial end of said housing reaching inwardly toward said axis and closing the space between said housing and said can at said one end to reduce power consumption in the twisting of a yarn paid off from said spool and emerging from said can and said housing at and end thereof, said axis being generally upright and said yarn emerging from the upper end of said can, said closure member being a cover displaceably mounted upon said housing, formed with an opening traversed by said yarn, and openable to afford access to the interior of said housing and said can, said can and said housing being cylindrical and coaxial with one another and said cover being a circular disk, said opening being provided at the center of said disk.
