Formation of a reserve winding thread of defined length on bobbins of a textile machine |
摘要 |
In a method and apparatus for winding yarn onto a bobbin in a textile machine in a manner to form a reserve winding at one end of the bobbin, the yarn forming the reserve winding is given an accurately determined length by drawing a length of yarn greater than the predetermined length into a suction device before commencing winding of a bobbin and then cutting the yarn at a predetermined point beyond the inlet end of the suction device at a time bearing a fixed relation to the catching of the yarn by a catch element associated with the bobbin. The timing of the cutting operation is controlled by monitoring the instant at which the inlet end of the suction device is moved to a position at which the yarn can be caught by the catch element.
