ABSTRACT:
BACKGROUND OF THE INVENTION
The invention relates to a spindle having a rotatorily driven spindle shaft; a twisting pot driven in rotation by the spindle shaft and having at its bottom a radially extending yarn guide channel; a rotatorily driven spool carrier for receiving a spool; a hollow axle centrally extending through the spool carrier and connected to the yarn guide channel; and a centering eye arranged on an extension of the hollow spindle axle.
The invention has the object to design a spindle such that it can be used either as a twisting spindle, especially a multi twisting spindle in the form of a two-for-one twisting spindle or a three-for-one twisting spindle, or a doubling spindle or a bobbin peg.
SUMMARY OF THE INVENTION
As a solution to this object the inventive spindle is characterized in that a placing member that can be introduced into the spool carrier and can be vertically reciprocated is provided for placing especially a doubled yarn removed from a bobbin creel onto a spool that is rotating on the driven spool carrier.
When it is desired to operate the spindle as a two-for-one twisting spindle, the spool carrier is secured in a conventional manner, for example, by a switchable solenoid coupling, against rotation.
In the case that the spindle is to be operated as a three-for-one twisting spindle, the spool carrier and the twisting pot are preferably rotated in opposite directions. For operation as a doubling spindle or bobbin peg, it is possible to eliminate the drive action of the twisting pot in order to save energy.
