McDermott, Coliingdale, Pa., assignor to American Viscose Corporation, Wilmington, Del., a corporation of Delaware Application November 19, N46, Serial No. 710,859
11 Claims.
This invention relates to the feeding and distribution of yarn, strands, threads or other filamentary material onto a moving belt or the like.
The main object of the present invention is to provide an improved device for distributing a yarn, thread, strand or other filamentary material in a regular fashion on a moving belt or the like.
Other objects and advantages of the present invention will .become apparent from a study of the following description of the drawings herein.
In the drawings,
Figure 1 is a front view partly in section of an illustrative embodiment of the present invention,
Figure 2 is a top view partly in section of Figure 1,
Figure 3 is a .back view of the driving mechanism of this invention, and
Figure 4 is an isometric view of an embodiment of the present invention showing one method of laying filamentary material upon a traveling belt or screen.
As shown in Figures 1 and 2, reference character I indicates a rotatable feed wheel mounted on a shaft 3. This shaft 3 is shown as a hollow member in the accompanying drawings. The feed wheel I has an apertured thread-carrying periphery. As illustrated in the preferred embodiment, the periphery of the feed wheel I is provided with spaced slots parallel to the axis of rotation and it is flanked :by a flange that has its inner periphery concentric to the axis of rotation of the feed wheel. An oscillatory nozzle 2 is disposed inward of the feed wheel periphery for directing a jet of fluid through the periphery. This fluid may be liquid or gaseous; as shown it is an air nozzle radially extending from the hollow shaft 3 and oscillating therewith.
The hollow shaft 3 is rotatably supported in the supporting member 8 by the bearing members II and I2. The bearing members may be roller or journal bearings or just bushings. The main consideration is that the hollow shaft 3 be readily rotatable or oscillatable therein. A conduit 4 which supplies fluid to the nozzle through the hollow shaft is made of an elastic material such as rubber.
Means are provided for oscillating the nozzle 2 and means are provided for rotating the feed wheel I. As illustrated in the preferred embodiment of this invention, a collar or eccentric disc 5 is suitably mounted on the hollow shaft 3. This collar 5 has a crank pin l3 attached therein, which is connected by a link 6 to a similar crank pin I8 mounted on a slidable block I I, suitably connected on another collar or crank disc I. This 7 on the drive shaft I6 is a sheave or pulley III- which .by virtue of a belt l9 or the like imparts rotation to the feed wheel l by a sheave 9 connected thereto. Although a sheave has been shown as a means for driving the feed wheel I, it is to be understood that these could be geared just as easily. A variable speed adjustment may be incorporated by the use of change gears or variable speed sheaves.
In operation, a yarn, strand, thread or other filamentary material, preferably in a wet condition, is fed over the apertures on the feed wheel I, adhering thereon and rotating with the feed wheel. The yarn or the like is carried around to the underside of the feed wheel, to a point where it is in contact with the fluid forced through the apertures by the oscillating nozzle 2. As the yarn is freed from the feed wheel it falls into layers due to the oscillation of the nozzle 2 and the rotation of the feed wheel.
Referring to Figure 3, the radial distance from the pin I3 to the center of the collar 5 must always be greater than the radial distance from pin i8 to the center of the collar 1 ,or oscillation of the nozzle 2 will not take place. However, the stroke of the nozzle 2 may be changed by varying the setting of the slidable block ll mounted on the collar 1 secured thereon by the set screw l1,
As described in the disclosure, there are two distinct ways of varying the lay of the yarn deposited. One by changing the speed of the feed wheel and the other by changing the stroke of the nozzle.
Although this invention has been described with reference to the improvements shown, it will readily be appreciated that numerous changes may be made without departing from the spirit and scope of the invention as described in the appended claims.
