ABSTRACT:
A textile yarn interlacing or intermingling jet nozzle 2 has a yarn channel 4, a threading slot 6 and an air inlet 8. The yarn channel 4 is formed between a top plate 40 mounted to a base 20 by bolts 70, 80 which secure both members to a nozzle support 90 to form the nozzle assembly. The threading slot 6 extends from one side and opens into the yarn channel so that a multifilament yarn can be inserted from the side. This threading slot 6 is formed by the lower surface 48 of a lip 46 on the top plate 40 and an upper surface 24 on the base. To insure that the sidewall 10 of the yarn channel through which the threading slot extends does not contain any sharp edges that could damage yarn, shoulders 34 and 42 are formed on the base 20 and top plate 40. When these shoulders abut, the upper and lower surfaces forming sidewall 10 are in the same plane and there are no offset or exposed edges to damage the yarn. The shoulders 34 and 42 are brought into abutment as a bolt 70 mounts the top plate 40 to the base 20. A camming sleeve 60, surrounding the bolt 70, has an inclined camming surface 62 which engages an opposed camming surface 54 on the upper surface of the top plate 40 to shift the top plate laterally until the shoulders abut.
