  • Device and process for the splicing of textile threads using compressed air and liquid
    Patent number: 6412262
    Abstract: A device (10, 10′) for the splicing of textile threads using compressed air and liquid, which includes a casing on which is assembled a splicing head in which is made a mixing chamber (11), at least one feed duct of air with added liquid which leads into the chamber (11), a valve which is controlled by the immission of compressed air and means to add the liquid to the compressed air before its immission into the chamber (11). The splicing head, with its chamber, is set in an isolated tank from which extends at least one channel for the discharge to the outside of the compressed air with added liquid device. The device (10, 10′) has means for creating suction in the water discharge channel or channels (15, 16, 22, 23). In addition, the object of the present invention is a process for the splicing of textile threads using compressed air and liquid.
