Improved twister device for a winding carriage enabling compact bobbins to be formed |
(57) This invention relates to an improved twister device (8) for a winding carriage collecting
onto a bobbin (12) the sliver (30) emerging from the gill box or derived machine.
More specifically, the present invention proposes a device which enables compact bobbins
(12) of cylindrical form to be obtained, by comprising drive means (1) which rotate
the rotary trumpet (7) of the known mobile twister (8) unit independently of the to-and-fro
linear movement of said mobile unit (8) of the winding carriage, to transmit single-direction
constant uniform rotation to the sliver sliding within the rotary trumpet before it
is deposited on the surface of the bobbin under formation.
