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.
Claims3
Device for dosing and injecting a small quantity of liquid into the splicing air entering the splicing chamber of a pneumatic yarn splicing device from a compressed-air source, comprising a compressed-air tube leading to the splicing chamber, a liquid container, and a combined dosing and atomizing valve connected between the compressed-air source and said compressed-air tube for conducting splicing air to said compressed-air tube, said valve having a dosing chamber formed therein receiving a given quantity of liquid, and said valve including means operated by splicing air from the compressed-air source for alternately connecting said dosing chamber to said liquid container and to the compressed-air source for injecting said given quantity of liquid into the splicing chamber.
