Definitions
- the invention relates to a device for guiding a yarn which is unwound from the front end of a yarn supply drum of a yarn feeder unit for looms, which device comprises a hollow body, which is disposed co-axially and in line with the yarn supply drum, wherein the hollow body has a larger diameter at its entry side facing towards the drum than at its exit side facing away from the drum, and wherein the hollow body includes a first axial zone adjoining the entry side and a second axial zone adjoining the exit side, and wherein the hollow body has an outlet eye at its exit side.
- Devices of the kind referred to above are generally known, for brevity's sake they are also called antiballoon devices.
- Devices of this kind are used with looms, wherein the weft thread is fed from a bobbin to the weft section of the loom via a yarn feeder.
- a yarn feeder In the yarn feeder, a specific amount of yarn is wound onto a yarn supply drum, which may or may not take place in separate windings . From said supply drum the yarn runs over the front end of the drum to the weft section of the loom, whereby the yearn is transported at a high velocity, for example by means of air jet injectors.
- a problem which occurs thereby is that the yarn, upon being unwound from the drum at a high velocity, tends to form a so-called balloon, which leads to all kinds of problems.
- the balloon In the first place there is a spatial problem, since the balloon, once it becomes too large, tends to strike against other parts of the device.
- a second problem is the fact that the balloon, as a result of the centrifugal forces occurring therein, causes the tension in the weft thread to increase, which eventually has an adverse effect on the quality of the woven product and on the feeding capacity of the loom.
- the truncated cone comprises a number of inwardly projecting interrupting and braking means in the form of studs or ribs on its internal surface provided.
- Said studs or ribs indeed reduce the degree to which the yarn and the inside surface of the cone are in contact with each other, which leads to a lower yarn tension, but the effect achieved by means of these devices is still unsatisfactory.
- the object of the present invention is to provide a device of the kind referred to above which exhibits an improved operation, and to this end it is characterized in that one or more axially spaced-apart, inwardly projecting ribs, which each lie in a separate plane extending transversely to the central axis of the hollow body, are present on the internal surface of the outlet eye.
- one or more axially spaced-apart ribs, which project inwardly and which each lie in a separate plane extending transversely to the central axis of the hollow body are present on the internal surface of the aforesaid second zone of the hollow body as well.
- the aforesaid ribs which lie in planes that extend transversely to the central axis of the hollow body, have a positive effect on the operation of the device, in the sense that the tension in the weft thread running through the device is further reduced, whilst also the forming of a balloon is further prevented.
- the yarn can be wound onto the supply drum by means of a winding arm which rotates in clockwise or in anticlockwise direction.
- the yarn windings on the supply drum can lie in planes which extend obliquely in a LO O to t H H ⁇ O L ⁇ o L ⁇ O L ⁇ en 3 N cn P P n P (U iu c 0 H- Hi TJ tr 01 CD a O CD rt « tr i tr O n 01 Pi
- inwardly projecting unevennesses which function as interrupting and braking means for the yarn, on the internal surface of the first zone of the hollow body.
- Said unevennesses may thereby be made up of corrugations or ribs extending substantially along the generating line of the conical surface.
- Figure 1 is a schematic view, not to scale, of a yarn feeder device.
- FIGS 2 and 3 are schematic, sectional views, not to scale, of two embodiments of the device according to the invention.
- Figure 4 is a schematic, sectional view, not to scale, of another embodiment of the device according to the invention.
- Figures 5 and 6 are sectional views of two possible embodiments of the device shown in Figure 4.
- numeral 1 indicates a frame carrying a winding drum 2.
- Yarn 4 is wound from a bobbin 3 onto yarn winding drum 2 by means of a winding arm 5, from which drum the yarn 4 is unwound by an air jet injector (not shown) of a loom.
- Frame 1. furthermore carries a stop element 6, which comes into operation the moment the unwinding of yarn 4 from the winding drum 2 is to be stopped.
- an unwinding device 7, which unwinding device 7 is frustoconical in shape and which has a smooth internal surface and a schematically indicated outlet eye 10.
- Winding arm 5 winds a supply of windings 8 onto winding drum 2, after which the yarn 4 is led to the loom over the front end of winding drum 8.
- a balloon 9 forms in the yarn thereby, which balloon has the aforesaid adverse effect on the yarn tension and which needs to be reduced as much as possible by unwinding device 7. It is not possible to achieve an optimum result with an unwinding device 7 having a smooth internal surface as shown in Figure 1.
- the unwinding device 7 that is schematically shown in Figure 2 is provided with an outlet eye 10, which is made of a wear- resistant material having good yarn guiding properties, and whose internal surface is provided with projecting ribs 11, which each lie in a separate plane, which extends perpendicularly to the central axis . It has become apparent that such ribs have a positive influence both on the yarn tension and on the dimensions of the balloon 9.
- a further improvement can be achieved by forming the second zone 28 of the hollow body, which adjoins the exit side, with three ribs 30, as is schematically indicated in Figure 3, which ribs project inwardly and which each lie in a plane which extends practically perpendicularly to the central axis 31 of the device.
- the embodiment is shown to comprise three ribs 30, it will be apparent that the number of ribs may vary, depending on the conditions of operation.
- the ribs are shown to be disposed in axially spaced- apart relationship on the conical surface, but it is also possible to arrange the ribs so closely together that they adjoin each other to form a corrugated pattern.
- the ribs may have mutually different heights. Surprisingly it has become apparent that such ribs 30 have a further positive influence both on the yarn tension and on the dimensions of the balloon 9.
- the device according to Figure 2 is made up of one frustoconical surface, it will be apparent that, as is schematically shown in Figure 4, zones 28 and 29 may also be made up of frustoconical surfaces having different apex angles.
- zone 28 is in the form of a hollow frustoconical surface having a smooth internal surface . It has become apparent that a further improvement of the device can be achieved by forming projecting interrupting and braking means, which may for example consist of ribs 32, on the internal surface of first zone 28, as is shown in Figure 4. Said ribs 32 thereby extend approximately along the generating line of the frustoconical surface, and they may be distributed separately over the internal surface of the hollow cone, as is shown in Figure 5, whereby the ribs may be spaced a constant or a varying distance apart.
- projecting interrupting and braking means which may for example consist of ribs 32, on the internal surface of first zone 28, as is shown in Figure 4.
- Said ribs 32 thereby extend approximately along the generating line of the frustoconical surface, and they may be distributed separately over the internal surface of the hollow cone, as is shown in Figure 5, whereby the ribs may be spaced a constant or a varying distance apart.
- the ribs 32 may also be arranged in a zig-zag pattern with slightly rounded peaks. It is noted that for the sake of clarity the inlet eye 10 of the devices that are shown in Figures 3, 4 and 5 is not shown.
