No. 25417 1 Claim. {(Cl.:57-36,)

This invention relates to spinning frames lwherein-a slubbing, roving, or sliver feedingpart and/ or .a slubbing, roving, or sliver drafting .part areor is enclosed in a chamber formed by a cover and cut off from outside .air, in said chamber is maintained at a temperature and a humidity suitable for spinning.

In spinning factories, it isa commonpractice'to efi'ect air conditioning such. that .air'throughout a'large. space is maintained at .a temperature and humidity suitable for spinning. It is,'therefore, impossible to locally maintain the air surrounding the roving or sliver feeding part and/or drafting part of the spinning frame at the temperature and humidity most suitable for. spinning.

The above air conditioning to be effected throughout 'the large space requires not only installation and much expenses, but also results in adherance of flying and dust to sliver while it is spun, thus rendering production of yarn having improved. quality difficult.

An object of my invention is to obviate the above disadvantages and spin an improved yarn in an extremely economical manner.

Other advantages are accomplished with my present invention. as explainedhereinafter and illustrated in the accompanying drawings, in which:

FIG. 1 is a verticallongitudinal sectional view of a spinningframe in accordance. with my invention wherein a roving or sliver feeding part only is cut off from outside air;

FIGS. 2 and 3 are vertical longitudinal sectional views of spinning frames in accordance with my invention wherein the roving or sliver feeding part and drafting part are cut off from outside air;

FIG. 4 is a front view of the spinning frame shown in FIG. 2 partly in section; and

FIG. 5 shows mutual relations of temperature and humidity in the spinning frame in accordance with my invention and those in a conventional spinning frame.

Referring now to drawings, and especially to FIG. 1, numeral 11 designates a spinning frame as a whole, numeral 12 is a roller stand, numeral 13 shows a drafting part, and numeral 14 designates a cover adapted to form a chamber 15 enclosing the upper part of the drafting part 13'. A creel 19 for supporting balling bobbins 18 is mounted in the chamber 1'5. Provision is made of a duct 16 communicated with a temperature and humidity adjusting room (not shown) and provided with a number of jet holes -17 opened inside the chamber 15. The jet holes 17 are adapted to feed air maintained at a temperature and a humidity most suitable for spinning into the chamber 15.

It is preferable to use the cover 14 made of transparent resin in order to facilitate the spinning operation.

It is most desired to add to the roving or sliver about of water by the humid air fed into the chamber 15. The roving or sliver to which a suitable quantity of humidity has been given becomes about 8.5% in water content when drafted at the drafting part 13, so that the roving or sliver can be spun under the most suitable condition.

FIGS. 2 and 3 show other embodiments of this invention wherein the sliver feeding part and also the sliver drafting part are cut off from the outside air by means of the cover. In these embodiments, the chamber is formed by a cover comprising a lower section 14 and an upper section 14 The lower cover section 14 encloses 3,073,106 Patented an. 1 5, '1 963 therein the sliver drafting :part 13 and the upper section 1 1 encloses therein the sliver feeding part consisting of balling .bobbins18 (FIG. 2) .or cans 20 (FIG. .3). vPro.- visioni is made of a number of apertures. 23l-at the bottom of the: lower ecover section 14 Theseiapertures 23 serve .toxgui'de the 'drafted yarn towards spools.24-. The lower cover section 14 is provid'ed at its 'frontrside with a.-door -22 adapted to be opened and closed. .-It is preferable that the upper cover section 14 is also provided with a suitable door which facilitates insertion .and removal of the balling bobbins or the cans.

As mentioned above, thisinvention is intended to provide a; spinning-frame wherein the roving or sliverlfeedin'g part and/or drafting part are or is enclosed in 'a-cha-mber having asma'll v0lume such .that the drafting processmay be effected at a temperature and a humidity most suitable .for spinning.

Thus, in: accordance with the present invention the. tem- .perature and humidity existing in-the roving or sliver feeding part and drafting part may locally be adjustedin .a mostefl'lcient -manner,-so that the installation becomes simple and less expensive if compared with. a conven tionalzspinning frame for which temperatureandrhumidity throughout a largespinning frame room .are to :be sad.- justed. .Moreover, v,adherance 'of the flying and dust to sliver :can never be occurred and .fiuffiness .and break. of yarn can be reduced," thereby obviating frequent clearing of the: spinning frame and rendering the maintenanceand management of the spinningframe" simple and easy. "Like this way, according 'to the present invention yarn of the highest grading may be obtained throughout all seasons.

FIGQS illustrates mutual relations of temperature and humidity in a spinning frame inaccordance with-rny invention and thosein a conventional spinning frame.

Table 1 shows results obtained by a spinning frame in accordance with my invention shown in FIG. 1. The yarn is No. 30s in count.
