Embodiment Construction

[0021] The method of introducing the end of the yarn A into the spinning nozzle 1 of the jet spinning machine takes place after a spinning interruption, e.g. due to a break of the yarn A in the operating unit or after completing the winding of a bobbin and replacing it with an empty bobbin After the wound bobbin. To resume spinning, use the end of yarn A found on the bobbin (respinning after yarn break) or use the auxiliary yarn on the auxiliary bobbin of the auxiliary device (after the package of a bobbin is completed or when resuming spinning after bobbin replacement).

[0022] The introduction of the end of the yarn A is carried out in such a way that after the interruption of spinning, the auxiliary device first finds the end of the yarn A wound on the bobbin or prepares an auxiliary yarn before the auxiliary device reaches the handling unit. This prepared or found yarn A is guided to the introduction at the part between the bobbin (an auxiliary bobbin or on which the for...

Abstract

The invention relates to a method for importing a yarn terminal (A) into a spinning nozzle (1) of a jetting spinning machine. The yarn (A) is transferred to an importing head (2) of an assistant device in importing process, the assistant device can be movably mounted along at least one row operation units, the operation unit can stay in front of the operation unit that is special and needs assistant, the importing head is used for transporting the yarn terminal (A) to an opening (11) of the spinning nozzle (1). When the yarn (A) moves to the importing head (2), the yarn (A) on the importing head (2) is guided to a limiting position, the yarn is held by the importing head and generates a yarn (A) end for importing, the end is held in a special position of the importing head (2), then is moved to an importing position of the opening (11) of the spinning nozzle (1), next, the yarn (A) end is released from the importing head holding and bears absorption force from the opening (11) of the spinning nozzle, straightly directs to the opening (11) of the spinning nozzle (1) and is absorbed into the opening (11) of the spinning nozzle (1) through the opening yarn end (A). The yarn end (A) is imported into the spinning nozzle (1) repeatedly for resuming spinning.

Description

technical field [0001] The invention relates to a method for introducing a yarn end into a spinning nozzle of a jet spinning machine, during which the yarn is transferred to an introduction head of an auxiliary device which is movably mounted along at least one row of operating units capable of Stopping in front of a specific operating unit that requires maintenance, the introduction head delivers the yarn end for its introduction into the opening of the spinning nozzle. [0002] The invention also relates to an auxiliary device for a jet spinning machine, which is movable along a row of operating units, the auxiliary device comprising an introduction head which, during an auxiliary operating unit, is adjustable into a position for receiving yarn after a spinning interruption, And it can adjustably enter into the introduction position of the yarn end to guide the yarn into the spinning nozzle. Background technique [0003] Difficulties during the introduction of the yarn en...
