Abstract
To effectively separate a broken end of a thread from a thread winding body a process and associated apparatus is herein proposed according to which at least two air streams are directed along the thread winding body and toward a suction air stream, with the air streams being displaced relative to one another in the peripheral direction of the thread winding body and variably inclined relative to the longitudinal axis of the thread winding body.
Claims23
A process for the pneumatic separation and sucking-in of a broken end of a thread from the truncated cone-shaped upper area of a thread winding body, comprising the steps of:
- (a) directing a stream of suction air to a suction source located in proximate relationship to the thread winding body;
- and
- (b) directing at least two air streams from a horizontally movable cradle member in a direction along the thread winding body and toward the suction air stream, wherein the at least two air streams are displaced relative to one another in the peripheral direction of the thread winding body and variably inclined relative to the longitudinal axis of the thread winding body.
In an apparatus for the pneumatic separation and sucking-in of a broken end of a thread from the truncated cone-shaped upper area of a thread winding body, comprising:
- a textile machine spindle defining an axis of rotation;
- a casing stuck onto the spindle;
- and a suction producing device located above the spindle, the improvement comprising horizontally movable cradle member means from which at least two air streams are directed along the thread winding body and toward the suction producing device, wherein the at least two air streams have a different slope relative to the spindle axis of rotation and are mutually displaced in the peripheral direction of the spindle.
