Definitions
- the sliver 3 is fed to the carder 2, which separates it into individual fibres.
- the individual fibres travel through the interspace 7 surrounding the carder 2 and are conveyed pneumatically through the channel 8 to the cavity of the rotor 9, which rotates at very high speed.
- a vacuum is generated within the cavity of the rotor 9 by the effect of its speed and the perforations 10, or by the action of a separate suction source, and sucks the fibres separated by the carder 2, withdrawing air both from the interspace 7 and through the aperture 11.
- This inflexibility means for example that if it is required to change the working speed of the spinning machine in order to produce a yarn of different characteristics, the transmission ratios in the end of the machine have to be changed, with the result that all the spinning units along the machine face must simultaneously produce the same yarn.
- All the aforesaid functions which can be required of the feed roller ie: - rotation at constant speed, - prefeed, ie rotational advancement through a determined angle, - retraction, ie counter-rotation through a determined angle, - progressive refeeding, ie restart of the roller in accordance with a determined speed/time relationship, are implemented by the electronic control system, which generates the necessary electrical digital signals.
