May 28, 1968 w. SLOWIAK RING SPINNING FRAME 3 Sheets-Sheet 5 Filed June 14, 1966 United States Patent 01 Claims. 61. 57-36) ABSTRACT OF THE DISCLOSURE A ring spinning frame with a drawing apparatus in which the delivery rollers thereof are offset at a distance from the axis of the spindle which is greater than that of the supplying rollers thereof situated above the delivery rollers. Furthermore, the spinning frame is equipped with a suction extractor having a suction nozzle which is fitted below the delivery rollers.
BRIEF SUMMARY OF THE INVENTION The invention relates to a ring spinning frame, and particularly to a ring spinning frame with a single stage drawing apparatus.
There are known ring spinning frames in which the roving runs from the roving rolls obliquely through the drawing apparatus to a yarn guide above the spindle and then vertically to the spindle, or from the roving rolls to the supply rollers of the drawing apparatus obliquely as in the frame mentioned before, then vertically through the drawing apparatus to the yarn guide above the spindle and then to the spindle. The first mentioned spinning frame is a wide machine, and is inconvenient for servicing, as members such as the roving rolls and the drawing apparatus are located far from the outer contour of the spinning frame. The second mentioned spinning frame has substantial height, and it is also inconvenient for servicing, since the roving rolls and the drawing apparatus are located at a high level, which requires the provision of additional steps along the spinning frame in order to permit servicing.
Recently, in spinning frames with a drumless spinning system (which enables substantial increase in the spinning rate) there has arisen the necessity of using large beams on the spindles, in order to increase the productivity of the spinning frame, which however causes an increase of the width of the machine.
The spinning frame according to the invention eliminates these disadvantages. The delivery rollers of the drawing apparatus are located further from the vertical axis of the spindle than the supplying rollers, which makes it possible to diminish substantially the width of the machine. Furthermore, by locating the delivery rollers of the drawing apparatus towards the rear of the spinning frame in relation to the supplying rollers, it then is possible for the roving to assume'a vertical position in the case of rupture of the roving in the drawing field, whereby the roving can be drawn from the supplying rollers of the drawing apparatus by a suction nozzle of a suction extractor, by-passing the roving device and the delivery rollers of the drawing apparatus. Moreover, the suction nozzle is positioned below the delivery rollers for receiving roving which is ruptured between the delivery rollers and the yarn guide. Thereby, the suction nozzle can extract roving which is ruptured before or after the delivery rollers. Thus the spinning frame according to the invention provides for extraction of ruptured roving by means of a single suction nozzle behind the delivery rollers of the drawing apparatus. This was quite impossible to realize in known spinning frames.
3,385,045 Patented May 28, 1968 BRIEF DESCRIPTION OF THE DRAWING The ring spinning frame according to the invention is shown by way of example in the accompanying drawing in which:
FIGURE 1 is a diagrammatic side elevation view of a ring spinning frame according to the invention;
FIGURE 2 shows on an enlarged scale a portion of the frame of FIG. 1;
FIGURE 3 is a view similar to that of FIG. 2 but of a modified version of the spinning frame.
DETAILED DESCRIPTION The spinning frame according to the invention comprises a roving roll 1, which cooperates with an uncoiling drum 2 such that roving is withdrawn from roll 1 and fed to supplying rollers 3, 4 of a drawing apparatus. The roving is fed from rollers 3, 4 to a roving device 5 which has the form of a roving coil as shown in FIGS. 1 and 2 or a rotary roving device as shown in FIG. 3. The roving is then engaged by delivery rollers 6, 7, 8 of the drawing apparatus and advanced through a yarn guide 9 to a spindle 10 where the roving is wound. A suction nozzle 11 of a suction extractor 12 is positioned below rollers 6, 7, 8 for a purpose to be described more fully hereafter.
The delivery rollers 6, 7, 8 of the drawing apparatus are positioned at a greater distance from the vertical axis of the spindle 10, than are the supplying rollers 3, 4. Therefore, the roving being uncoiled from the roving roll 1 by means of the uncoiling drum 2 passes obliquely between the supplying rollers 3, 4 of the drawing apparatus toward the outside of the spinning frame. The roving runs from the rollers 3, 4 to the roving device 5 and to the delivery rollers 6, 7, 8 of the drawing apparatus, obliquely towards the inside of the spinning frame, and then obliquely towards the outside of the spinning frame as it proceeds to the yarn guide 9. Such manner of oblique guiding of the roving towards the inside of the spinning frame between the supplying rollers 3, 4 and delivery rollers 6, 7, 8 of the drawing apparatus has the advantage not only of minimizing the size of the frame and simplifying service but it has the additional advantage that in the event of rupture of the roving in the drawing field, the roving assumes a vertical position, as shown in FIGS. l-3 in dotted lines, and can be extracted in the suction nozzle 11 of the suction extractor 12, which feeds the ruptured roving behind the delivery rollers 6, 7, 8 of the drawing apparatus. The position of suction nozzle 11 below delivery rollers 6, 7, 8 and adjacent to the oblique path of travel of the roving from rollers 6, 7, 8 to guide 9 enables the nozzle 11 to extract roving which may become rup tured after passing through the delivery rollers. Thus, the nozzle can extract roving which is ruptured before or after the delivery rollers 6, 7, 8.
The ring spinning machine according to the invention has considerably smaller overall dimensions both as regards height and width than spinning frames used hitherto, which considerably simplifies the servicing of the machine, while the machine retains the proper technological process of spinning.
What I claim is:
1. A ring spinning frame comprising a drawing apparatus including supply rollers and delivery rollers arranged in spaced relation, means for feeding roving to the supply rollers of the drawing apparatus, the roving advancing through the drawing apparatus from the supply rollers to the delivery rollers, a spindle for receiving roving which has passed through the drawing apparatus and means for guiding the roving to the spindle from the delivery rollers of the drawing apparatus, said spindle having an axis, said delivery rollers being offset from said axis of the spindle, said supply rollers being located closer to the axis of the spindle than are the delivery rollers such that the roving travels along an oblique path from the supply rollers to the delivery rollers and then along a different oblique path from the delivery rollers towards the spindle.
2. A frame as claimed in claim 1 wherein the obliquity of the path of travel of the roving from the supply rollers to the delivery rollers is less than that of the roving from the delivery rollers towards the spindle.
3. A frame as claimed in claim 1 comprising suction means adjacent the delivery rollers for receiving roving which is ruptured along the path from the supply rollers to the delivery rollers and along the path from the delivery rollers towards the spindle.
4. A frame as claimed in claim 3 wherein said suction means includes a nozzle disposed below the delivery rollers facing laterally thereof towards the supply rollers.
5. A frame as claimed in claim 3 wherein said spindle is vertical and the delivery rollers are located higher than the spindle and the supply rollers higher than the delivery rollers, said suction means including a nozzle disposed below the delivery rollers and below the path of travel of the roving from the delivery rollers towards the spindle, said nozzle being placed laterally of the delivery rollers towards the supply rollers such that if the roving is ruptured between the supply and delivery rollers, the free end will tend to fall vertically from the supply rollers and be received by the nozzle.
