Abstract
A method for metering and injecting small amounts of fluid into the splicing air of a splicing head of a compressed gas thread splicing device including a metering valve having a piston with a metering chamber formed therein, the metering chamber having a given volume determining the amount of fluid to be injected, the piston being slideable between a loading position and an injecting position of the metering chamber, a circulating fluid circuit connected to the piston, and a compressed gas circuit connected from the piston to the splicing head, which includes connecting the metering chamber to the circulating fluid circuit in the loading position before splicing, moving the piston from the loading position to the injecting position, and subsequently bringing the metering chamber in contact with a compressed gas current in the compressed gas circuit flowing into the splicing head as splicing air at the moment the fluid is to be injected for splicing, and a device for carrying out the method.
