Abstract
Process to set the optimal working height between the thread entry point and the thread exit point in a twisting and/or thread spinning machine, and a twisting and/or thread spinning machine that applies such process including: identifying the variation of tension of the thread produced by the variation of the winding diameter (d) of the thread (8) on the bobbin (5), depending on the position of the rocker (6), or the winding diameter of the thread on the bobbin (5); carrying out the displacements from the thread entry point (PE) and/or from the thread exit point (PS) to obtain a distance (LB) between both in which the variations of tension counter each other.
Claims
exact text as granted — not AI-modified1 . A process to set the optimal working height between the thread entry point (PE) and the exit point (PS) on a twisting and/or thread spinning machine ( 1 ) that operates with two or more balloons (B), that comprises
feeding means ( 2 ) of the untwisted thread ( 8 ), guiding means ( 3 ) that define the thread entry point (PE) at the upper part of a twisting area ( 4 ), a cursor that slides on a ring or rocker ( 6 ) and that defines the thread exit point (PS) at the lower part of the twisting area ( 4 ), the thread exit point (PS) being mobile in height, and collecting means of the twisted thread or bobbin ( 5 ) with a winding diameter (d) of the thread on the bobbin ( 5 ), the distance (LB) being the height of the twisting area ( 4 ) located between the thread entry point (PE) and the thread exit point (PS) where the thread ( 8 ),
characterized in that it comprises a step where the distance (LB) increases or decreases by displacing dynamically the thread entry point (PE) and/or the thread exit point (PS) so that the variations of the tension of the thread ( 8 ) produced by the variation of the winding diameter (d) of the thread ( 8 ) on la bobbin ( 5 ) counter each other, achieving a constant tension on the thread during the working cycle of the spinning or twisting process.
2 . The process to set the optimal working height between the thread entry point and the exit point in a twisting and/or thread spinning machine, according to the claim 1 , characterized in that the distance LB between (PE) and (PS) increases when the thread winding diameter on the bob-bin is from most to least, and a step where the distance LB between (PE) and (PS) decreases when the thread winding diameter on the bobbin is from least to most.
3 . The process to set the optimal working height between the thread entry point and the exit point on a twisting and/or thread spinning machine, according to claim 1 , characterized in that the proportion between the increase or decrease of the height thread exit point (PS) and the increase or decrease of the height thread entry point (PE) is between 1/1,01 and 1/50.
4 . The process to set the optimal working height between the thread entry point and the thread exit point in a twisting and/or thread spinning machine, according to claim 1 , characterized in that, in addition, to calculate the said optimal distance (LB) the following steps are carried out:
introduction of variables of the thread ( 8 ); its mass, and the variables of the machine ( 1 ); the radius of the ring or rocker ( 6 ) and the collection radius of the bobbin ( 5 ), introduction of the coefficients:
of friction of the thread ( 8 ) with the air,
of friction of the thread ( 8 ) with the fastening means ( 6 ),
