摘要
The invention relates to the attending of device for attending operating unit of the jet spinning machine, the attending device is adjustable along a row of operating units of the jet spinning machine, while the attending device comprises the working means out of which at least some can be displaced between their rest position and at least one working position. The attending device is in its lower section on level under the spinning nozzle (1) in operating unit of the machine provided with an adjustable suction tube (13), which is on its mouth provided with yarn brake (14), and which is further provided with yarn presence sensor (15) in cavity of suction tube (13) and with means (16) for yarn end preparation, while above the suction tube (13) is arranged an adjustable introducing head (17) of the spinning-in yam end equipped with clamp, while to the introducing head (17) there is assigned the adjustable yarn breaker (19) and swing arm (36) and above the introducing head (17) is arranged the adjustable underpressure compensator (20) and adjustable underpressure yam reservoir (21), above which is situated the guiding tube (22) of auxiliary yarn (33), to whose inlet of auxiliary yam (33) is assigned the feeding device of auxiliary yam (33), and auxiliary bobbin (18) of auxiliary yam (33) and guiding tube (22) of auxiliary yarn (33) is further provided with inlet (24) of pressure air and with means (25) for yam breakage, while the attending device further comprises the adjustable multifunction nozzle (26) with longitudinal suction opening (27) on which there is mounted the adjustable shutter (28) of a section of width of longitudinal suction opening (27), the knife (29) for yam breakage and yarn transposer (30) onto the tooth plate (31) of winding device (8) in the operating unit, while the attending device and/or each operating unit is equipped with adjustable catching hook (32) and auxiliary draw-off rollers (38). The invention also relates to several methods of manipulation with yam in operating unit of the jet spinning machine.
