No. 6,178 6 Claims. ((31. 19.35)
This invention relates to a machine for the production of spun yarn from a heavy tow composed of a plurality of continuous filaments. More particularly it relates to a drafting apparatus for such a machine.
In the conversion of tow into spun yarn bythe stretchbreak system a set of back or feed rolls draws a bundle of continuous filaments into a drafting zone where the filaments are broken by passing the bundle through a set of front or delivery rolls driven at a surface speed substantially higher than the surface speed of the feed rolls. Various novelty yarns may be made by combining two or more dissimilar materials to form the bundle supplied to the feed rolls. For example, an end of crepe yarn may be combined with untwisted tow to produce a slub yarn. The crepe yarn merely snap breaks while the tow is broken and drafted to form a spun yarn which contains short lengths of crepe yarn in the form of slubs. It will be recognized that satisfactory results can be obtained with this apparatus only if the required roll pressure can be maintained at all times in both the feed and the delivery roll systems. It will also be recognized that the bundle of broken filaments should be confined to the normal drafting path of the apparatus. Air currents may displace fibers from this path. When making a slub yarn as described above the broken crepe ends tend to form kinks or coils which may escape from the normal drafting path and even become entangled with the running gear of the machine. in any event, these kinks or coils will not be incorporated properly in the spun yarn to form the desired slubs.
It is therefore an object of this invention to provide means for confining the fiber bundle to the drafting zone of a stetchbreak spinning machine.
it is a further object to provide a stretch-break spinning machine fiber bundle confining means which may be varied in length with the length of the drafting zone of the machine.
It is another object to provide self-threading means for confining the fiber bundle to the drafting zone of a stretch-break spinning machine.
Other and further objects of this invention will be apparent to those skilled in the art to which it relates and from the following specification and claims and from the drawing.
Referring to the drawing briefly:
FIG. 1 is a side view of a spinning place of a stretchbreak spinning machine incorporating this invention;
FIG. 2 is a front view of a drafting apparatus of the machine;
FIG. 3 is a side view, partly in section, of the feed roll system of the drafting apparatus;
FIG. 4 is a sectional view along line 4-4 of FIG. 3;
FIG. 5 is a sectional view along line 5-5 of FIG. 1;
FIG. 6 is side section of a draft tube;
FIG. 7 is a sectional view along line 77 of FIG. 6;
FIG. 8 is a plan View taken along line 8-8 of FIG. 7; and
FIG. 9 is a sectional view along line 9-9 of FIG. 7.
A stretch-break direct spinning machine consists of a tow breaking and drafting apparatus, and a spinning system, such as a conventional cotton spinning system. The
breaking and drafting apparatus breaks the tow into a.
sliver of staple fibers and drafts the sliver to the extent required for the production of a spun yarn of the desired count. This drafted sliver is passed directly to the spinning system where it is converted into a spun yarn. Since the spinning system per se is conventional, this portion of the machine will not be described in detail.
Referring now to FIGS. 1 and 2 it will be seen that feed rolls 11 and 12 of the tow breaking and drafting apparatus shown are mounted on shaft 13 which extends the length of the machine and which is provided with similar pairs of feed rolls at each of a plurality of positions. Shaft 13 is power driven through suitable gears at the end of the machine. Feed rolls 14 and 15 are mounted on shaft 16 which is horizontally movable in a pair of slots 17 and 17a formed by two pairs of members 18, 19 and 20, 21 extending outwardly from the free end of bracket 22. Bracket 22 is firmly secured to horizontal support member 23 which, in turn, is firmly secured to vertical support members 24, commonly known as roll stands. Feed rolls 25 and 26 are mounted on shaft 27 which is horizontally movable in slot 28 in yoke 31, an extension of housing 29. Yoke 31 has an inwardly facing horizontal slot 32 across its free end 33. This free end of yoke 31 is positioned between the pairs of outwardly extending members 18, 19 and 20, 21 of bracket 22 so that the buttonhead of rivet 34, positioned One end of bellows 37 in cavity 30 bears against washer 38 which is secured to housing 29 by means of snap ring 39, while the other end of the bellows bears against head 4t? of plunger 41. Plunger 41 passes through a bore in housing 29 and yoke 31 located so that against shaft 27 causing rolls 25 and 25 to come into contact with rolls L1 and 12. Then since shaft 27 is slideably carried by support bracket 43, housing and yoke move inwardly until the buttonhead of rivet 34 is pressed against shaft 16, causing rolls 14 and 15 to come into contact with rolls 11 and 12. Since bellows 37 acts on both shafts both sets of rolls are under the same pressure. The corresponding rolls of the other positions of the machine will be under the same pressure because fluidis supplied to all bellows from a common manifold. Any pressure variation at one position, resulting from unevenness in the material being processed or the like, will be distributed over the entire machine through this common manifold and thus minimized. Pressure can be applied to or released on all sets of rolls by means of a fluid supply control for the entire machine.
The delivery roll System is similar to the feed roll system and can therefore be described quite briefly. De livery rolls 111 and 112 for each position are mounted on the shaft 113 which is power driven through suitable gears at the end of the machine. Delivery rolls 114 and 115 are mounted on shaft 116 which is horizontally movable in slots 117 and 1170, formed by pairs of members 118, 119 and 120, 121 extending outwardly from the free end of bracket of the desired count.
The rounded end of plunger 141, actuated by a bellows system. identical with that in housing 29, can be pressed into a conical detent in shaft 127.
When compressed air or other fluid is admitted to the bellows through manifold 144' and flexible tubing 145, rolls 125 and 126 and rolls 114 and .115 are brought into contact with rolls 111 and 112 under the desired pressure, as explained earlier in the description of the feed roll system. Members 146 and 147 of a bracket secured to the under side of bracket 122 straddle member i148 extending upwardly from yoke 131 just above shaft 127 and thus limit the upward movement of the shaft and yoke in addition to maintaining alignment between yoke 1'31 and bracket 122.
Draft tube assemblies 46 and 47 extending from a point close to the nip of rolls 11 and to a point close to the nip of rolls 111 and 114, and from a point close to the nip of rolls 12 and 26 to a point close to the nip of rolls 112 and 115, confine the slivers to the normal drafting paths of the apparatus. Elongated tubular member 43 of such an assembly has an upwardly facing longitudinal slot 49 and fins 50' and 51. The upper section52 of the assembly has a bore with two side slots to receive tubular member 48 and fins 50 and 51, shoulder 53 to serve as a stop for the tube, and a flared opening 54 extending outwardly from the shoulder. Upwardly facing flared slot 55 is aligned with slot 49* of the tubular member. The lower or condenser section 56 of the assembly has a bore with two side slots to receive tubular member 48 and fins 50 and 51, shoulder 57 to serve as a stop for the tubular member and a flared opening 58 extending outwardly from the shoulder and terminating in anarrow vertical slot 59 aligned with slot 49 of the tubular member. Upwardly facing flared slot 60 is also aligned with slot 49 of the tubular member. To mount the assemblies in operating position on the machine a small shaft 61 secured to bracket 122 is passed through hole 62 in condenser section 56 and a shaft 63 on arm 64 secured to bracket 22 is passed through hole 65 in 'upper section It will be understood that the length of the tube is governed by the distance between the feed and the delivery rolls. When it is desired to vary this distance it ismerely necessary to replace tube 48 with a similar tube of suitable length. A tube having an inside diameter of one-half inch has been found to be generally satisfactory for the processing of 1,000-8,000 denier tow. Crepe or other novelty effect yarn of 100-700 denier may be incorporated with this tow, if desired. The vertical terminal slot in the condenser may 'be 1/16-3/16 inch wide.
To operate the machine packages of tow 66 and 67 on arbors 68 are placed in notches 69 of fork members 70 of the creel. Tow ends 71 and 72 are drawn through guides 73 positioned on longitudinal channel 74 secured to the lower side of creel support member 75.
The ends of tow are passed about one or more guides 7 6 positioned along yoke 31 to apply a slight tension and to position the tow on the center lines of the spindles. The ends are then passed into the nips of rolls 11 and 14 and of rolls 12 and 15, respectively, and then into the nips of rolls 11 and 25 and of rolls 12 and 26, respectively. The slivers are passed through the nips of delivery rolls 111 and 114 and of delivery rolls 112 and 115, respectively. Delivery rolls 111 and 112 are driven at a substantially higher speed than feed rolls 11 and 12 to break the filaments and to draft the resulting slivers to the extent required for the direct production of spun yarn If the sliver is now laid above the upwardly facing slots of the tube assembly it will be drawn into the tubular member. After leaving the delivery roll system the slivers pass through thread guides 77 to ring twisters 78 where they are converted into spun yarn.
If desired a second tow or thread 7101, differing in some respect from the first tow, may be combined with tow 71 in the drafting apparatus to produce a novelty spun yarn. For example, if a crepe yarn is combined with untwisted tow the drafting apparatus will snap break the crepe yarn to produce spun yarn containing slubs of crepe yarn. It will be understood that more than one novelty eflect tow or thread may be used.
The tube confines the elements of the sliver to the normal drafting path of the apparatus. When an apron or a trough is used in place of the tube air currents may blow free filaments ends about, even causing them to be caught up by the running gear of the machine. When crepe yarn is combined with untwisted tow the broken crepe ends tend to form coils or kinks which may be caught up by the running gear of the machine, or exert sufficient pressure against the side walls of a wide trough to prevent the continued passage of the sliver. In any event these crepe ends do not remain properly positioned in the sliver to form the desired slubs. The tube confines the crepe slubs to the sliver bundle to produce a satisfactory spun yarn even when the'crepe yarn is of relatively heavy denier.
It is to be understood that a machine of this type consists of a plurality of the drafting and breaking places described arranged to form a double sided machine. The roll pressures at all places on the machine are the same because the pressure is applied through the common manifolds.
