7 Claims.
My invention relates to a mechanism and method for winding strands, threads, etc. on a spool, tube or the like, for forming a package. More particularly the invention relates to a mandrel or holding device for holding a spool or tube while the strand is being wound there on at a high speed.
Considerable difiiculty is experienced with conventional devices for holding the spool or tube, owing to the fact that as the package is build up thereon, the tube is compressed upon the holder with such force that it is difficult to remove. An object of the present invention is to overcome this difficulty by the provision of a mandrel or holder provided with gripping means which operate by centrifugal force to exert an expansive gripping pressure on the interior of the tube which is being wound. As such holding force is exerted on the tube only during rotation, the tube may readily be removed when the winding is completed.
practically uniform distribution of pressure or tension will obtain throughout the package when the latter is filled and removed from the winding spindle.
Other objects of the invention will appear hereinafter.
Referring to the accompanying drawings:
Fig. 1 is a diagrammatic view of an apparatus for producing and winding a strand of siliceous material such as glass or the like;
Fig. 2 is a longitudinal section of a mandrel and a tube thereon, the mandrel being mounted on a winding spindle;
Fig. 3 is a section at the line 3-3 on and Fig. 4 is a perspective view of a centrifugally operated gripping bar or rib.
Referring particularly to Fig. 1, a conventional apparatus is illustrated for forming a sliver of siliceous material and winding it to form a package. This apparatus comprises a furnace 5 provided with a bushing 6 in the floor thereof, said bushing formed with a multiplicity of outlet openings, through each of which a Fig. 2;
, stream of molten glass or the like issues condrawn are guided convergently over a collecting spool or guide 9 by which they are accumulated into a single sliver or strand ill. The guide 9 may also serve as a means for applying a coating material to the filaments in a conventional manner.
As the strand is wound, it is distributed over the spool by means of a traversing device H which may comprise a disk rotating at a high speed. Fingers I2 extending radially from the periphery of the disk engage the strand l0 and carry it rapidly across the spool or tube on which it is being wound. As each finger releases the strand, the latter is automatically returned and then engaged by the next succeeding finger. In this manner the strand is uniformly distributed as it is wound to form a package.
Referring to Figs. 2, 3 and 4, the holder IS on which the strand is wound may be in the form of a tube, spool or the like. This tube is supported during the winding operation on a mandrel or holding device mounted on a spindle I6 which is continuously rotated at a high speed. The mandrel comprises a cylindrical body or drum ll formed adjacent its inner end with a hub 98 mounted on a tapered section of the spindle and clamped in position by a collar 19 threaded on the shaft. The mandrel includes an intermediate section 20 in the form of a tube or sleeve mounted on the shaft and clamped in position by the head 2| threaded on the shaft and locked in position by a' locking nut 22. The drum H is formed with an annular series of slots 23 extending lengthwise thereof parallel with the axis of the spindle. In each of the slots 23 is mounted an expansion bar or rib 24 which extends lengthwise of the slot, each rib being formed with shoulders 25 which engage the inner surface of the drum and limit the outward movement of the rib. The ribs are of sufficient depth to extend through the wall of the drum and protrude a short distance beyond the outer cylindrical surface.
The section 20 of the mandrel is provided adjacent each end with a disk-like or flange portion 27, the periphery of which lies .in close proximity to the interior surface of the drum 17. The flange portions 21 are formed with radially disposed openings or bores 28 in alignment with the slots 23 and forming pockets to receive coil springs 29 which exert an outward pressure on the ribs 24. The ribs are formed with beveled surfaces 3!! at the ends thereof to facilitate placing of the tube I5 on the drum. The tension of the springs is such as to hold the expansion ribs 24 against the inner face of the tube IS with a moderate pressure such that the said tube may be easily slipped into position on the mandrel and easily removed when the package has been completed. The tube I5 or spool is made of somewhat flexible, resilient material which will permit the tube to expand when internal pressure is applied thereto by the expansion bars under the influence of centrifugal force, and to contract when such force is discontinued, said expansion and contraction serving for a purpose which will presently appear.
The operation may be described as follows. When a tube l5 has been placed in position on the stationary mandrel, the latter is set in motion and brought up to a high speed rotation so that the sliver I0 is thereby wound on the tube, being uniformly distributed thereover by the traversing means ll, l2. At the commencement of rotation, the tube is held in place by the moderate pressure of the springs acting through the ribs 24. As the speed of rotation is accelerated, the centrifugal force applied to the expanding ribs greatly increases the pressure thereof against the inner face of the tube. This pressure causes the ribs to expand the tube slightly owing to its elasticity and to grip it firmly.
As the winding progresses and the strand accumulates, a considerable force is exerted on the tube. This force progressively increases with the number of convolutions or windings of the strand, the peripheral or winding speed increasing at the same time owing to the increasing of the diameter of the package. The expansive force applied to the tube by the ribs 24 serves to partly neutralize or counteract the force exerted by the winding of the strand on the tube. The effect of this is such that when the package has been completed and the tube with the package thereon-is removed from the mandrel, the pressure or tension of the strands is distributed practically uniformly throughout the package. The flexibility of the tube is suflicient to facilitate such uniform distribution and pressure.
The mass of the expansion bars or ribs 24 is so adjusted that the centrifugal force will counter-balance the tension applied to the material as it is being wound, in a manner to effect said uniform distribution of pressure in the finished package. It will be understood that the mass or weight of the bars 26 may be adjusted to suit the flexibility of the tube in order to obtain such result. If, for example, there is too great a mass in said ribs, the excessive centrifugal force will over-distend the tube so that when such force is discontinued and the tube contracts, the package of wound material will be comparatively loose on the tube surface. On the other hand, if the mass is too small, the fibers next to the tube will be under too great a pressure so that difiiculty may be experienced in the attempt to unwind the package,
It will be understood that the winding speed may be varied within wide limits, with a consequent variation in the centrifugal force Which is developed. The expansion bars are accord ingly designed to correspond to the particular speed which is being employed. For example, it has been found that with a speed of 6,000 R. P. M., ribs of the design herein illustrated, develop an outward pressure of about lbs. each. Much higher speeds are sometimes employed with apparatus of the type herein illustrated.
The amount of centrifugal force and the flexibility of the tube which are needed for obtaining the desired results, also depend in a measure on the flexibility or stretchability of-the sliver which is being wound. Slivers formed of glass or siliceous material generally have little stretchability as compared with those consisting of organic fibers.
Modifications may be resorted to within the spirit and scope of the appended claims.
