Abstract
The compressed-air tubing (5) leading to the splicing chamber (1) of the yarn splicing device is provided with a combined dosing and atomizing valve (7) through which the splicing air passes and which can be actuated by the splicing air injected. The dosing and atomizing valve (7) has a dosing chamber (22) which is connected alternately to a container of liquid and to the splicing air passing through the valve (7). The splicing air injected encloses the valve-cone (19) like a ring, thereby dragging along and atomizing the pre-dosed liquid.
