A spinning apparatus with continuous adjustment of a yarn accumulation system includes at least one spinning head including a spinning device including a spinning chamber for yarn production, a reel on which yarn produced by the spinning device is wound, the reel being rotatably influenced by a yarn guide shaped to impart a rotation movement of the reel for winding the yarn and a traversing movement of the yarn winding on the reel, an accumulation device arranged between the spinning device and the reel and shaped to create a reservoir of yarn not wound on the reel, a joining device including joining means to join together a first yarn end associated with the spinning device and a second yarn end associated with the reel, and a processing and control unit programmed to control the yarn guide to adjust accordingly the amount of yarn accumulated in the accumulation device.

A traversing unit for traversing a yarn with respect to a pair of delivery rollers of a workstation of a textile machine includes a yarn-guiding unit, a single traversing drive configured with the yarn-guiding unit, and a conversion element configured with the single traversing drive such a rotational movement () of the single traversing drive is converted into a linear, reciprocating movement of the yarn-guiding unit. The single traversing drive is a rotating motor. A sensor is disposed to detect at least a middle position of the yarn-guiding unit.

A traversing element is provided for a spinning machine that produces a roving. The traversing element includes a guide segment disposed to guide the roving onto a surface of a tube or a roving bobbin, and a support segment. The guide segment is configured at an end of the support segment and an opposite end of the support segment is connectable to a support of the spinning machine. A closed cavity is provided in the traversing element, the closed cavity partially filled with a liquid. Heat that occurs in the guide segment due to friction between the guide segment and the roving when the traversing element is operating is absorbed by the liquid.

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).
