Abstract

A yarn ring spinning and/or twisting machine with multiple balls, comprising means to move the relative position of the yarn guide (8) with respect to the yarn exit point (Y1) from the yarn feed means (1) with a trajectory (T) not aligned with the axis of rotation (V) during a spinning cycle, such that the trajectory of the yarn along a lower area (LB) between the yarn guide (8) and the cursor-ring assembly (5), where at least 2 balls are formed, does not foul the yarn collection means (4) in order for the spinning process to be stable. Preferably, the trajectory (T) of the yarn guide (8) has a first section which moves the yarn guide (8) on the axis of rotation (V) of the yarn collection means (4), and a second section which moves the yarn guide (8) away from the axis of rotation (V) of the yarn collection means (4).

Dependent claims

A yarn spinning and/or twisting machine with rings that operates with multiple balloons comprising:

yarn feeding means (1) with a yarn exit point (Y1),
yarn picking means (4) with a spin axis (V),
a yarn guide (8) located between the yarn feeding means (1) and the yarn picking means (4),
balloon diameter generating means (DB) consisting of a traveller-ring assembly (5) that is vertically movable and concentric with the axis (V),
drive means connected to the yarn picking means (4),
wherein the yarn spinning and/or twisting machine further comprises means for moving the relative position of the yarn guide (8) with respect to the yarn exit point (Y1) of the yarn feeding means (1) with a path (T) not aligned with the spin axis (V) during a spinning cycle, such that the path of the yarn along a lower area (LB) between the yarn guide (8) and the traveller-ring assembly (5), in which it forms at least 2 balloons, does not collide with the yarn picking means (4) so that the spinning process is stable.
