Abstract
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 traversing element for a spinning machine that produces a roving, the traversing element comprising:
- a guide segment disposed to guide the roving onto a surface of a tube or a roving bobbin;
- a support segment, the guide segment configured at an end of the support segment and an opposite end of the support segment connectable to a support of the spinning machine, the support segment comprising an elongated support arm;
- a closed cavity provided in the traversing element, the closed cavity partially filled with a liquid, wherein 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;
- wherein the cavity is defined at least in part in an interior of the support arm;
- and
- wherein the cavity is closed off by a guide element, the guide segment configured on the guide element.
A traversing element for a spinning machine that produces a roving, the traversing element comprising:
- a guide segment disposed to guide the roving onto a surface of a tube or a roving bobbin;
- a support segment, the guide segment configured at an end of the support segment and an opposite end of the support segment connectable to a support of the spinning machine, the support segment comprising an elongated support arm;
- a closed cavity provided in the traversing element, the closed cavity partially filled with a liquid, wherein 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;
- wherein the cavity is defined at least in part in an interior of the support arm;
- and
- wherein at least a portion of the cavity is enclosed by a pipe wall of a heat pipe, at least part of the heat pipe arranged in the interior of the support arm.
A spinning machine, comprising:
- a spinning nozzle that produces a roving from a fiber bundle supplied to the spinning nozzle;
- a winding device that winds the roving produced by the spinning nozzle;
- the winding device further comprising a movably mounted traversing element that guides the roving in a traversing manner while the roving is wound onto a tube during operation of the spinning machine;
- the traversing element further comprising:
- a guide segment disposed to guide the roving onto a surface of a tube or a roving bobbin;
- a support segment, the guide segment configured at an end of the support segment and an opposite end of the support segment connectable to a support of the spinning machine;
- and
- a closed cavity defined in the traversing element, the closed cavity partially filled with a liquid, wherein 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.
