Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The invention is an inverted feed as described in the main claim.
It relates to a continuous ring spinning machine. More specifically, the present invention relates to a continuous ring spinning machine adapted to be fed with rovings arriving from below. This invention is suitable for use in the textile industry. In particular, cotton is spun and twisted.
It is used in the final process.

[0002] In spinning, roving manufactured by various spinning machines is a beating,
After undergoing the carding and combing work, the final drawing work is carried out, with sufficient twist to prevent the fibers from sliding when under tension, A continuous and constant strong thread is formed. This thread is then wound onto a bobbin or tube.

For this reason, intermittent mules spinning machines are rarely used. The continuous spinning machine comprises a plurality of drawing devices and a plurality of fixed spindle holders. The spindle forms the support member for a suitable tube on which the yarn is wound.

The yarn feeding device in conventional systems comprises a plurality of large roving packages and a suitable roving-guide system located above the spinning unit. The rovings are continuously guided downwards by a roving-guide system in the vicinity of the drawing device and pass through this process step, after which they are conveyed by the yarn guide loops to the vicinity of the traveler ring. The traveler ring cooperates with a rotating ring that is rigidly fixed to a movable ring rail that can move up and down. By moving the ring rail up and down and rotating the spindle, the yarns can be wound in concentric layers.

[0007]

The lower feeding system of these spinning devices has some major drawbacks. First, for obvious functional reasons, the roving feeding element must have a structure suitable for heavy roving packages or similar elements. It is not possible to use another device such as a can or similar container.

Furthermore, it is not possible in a simple way to install an automated system which replaces the roving supplying element when it has been used up.
This is because such parts are very heavy.
