Abstract

ABSTRACT OF THE DISCLOSURE

An array of fibers is passed in contact with a contact surface, creating a frictional drag force on the fibers. The drag force is modified to bring the fibers in the array to a uniform alignment in order to more easily divide the array into bundles of fibers using a splitter.

Description

This invention relates to the handling of an array of fibers, splitting the array of fibers into bundles and collecting the bundles.
In known fiber collecting operations fibers in an array are passed into contact with a surface, which can be an applicator surface, and are then collected, usually by being wound into a package on a winder. A comb-like splitter is often inserted into the array of fibers just below the applicator surface to divide the fibers into bundles and to produce a split-strand package.
The splitter physically separates the array of fibers into bundles of fibers.
Heretofore the insertion of the splitter into the array has been a time-consuming task, requiring a manual separation of the -array into bundles. In known apparatus the fibers of the array generally do not assu~e a uniform alignment and are continually "dancing" i.e. moving laterally relative to each other. This lack - of uniformity of alignment of the fibers makes separation of the array into bundles even more difficult and it is especially difficult to obtain bundles with approximately equal numbers of fibers.
The present invention seeks to provide a method and appara-tus enabling this difficulty to be avoided or at least reduced.
According to one aspect of this invention there is provided a method of collecting an arra~ of fibers comprising passing said array of said fibers in contact with a contact surface, and con-tact producing a first frictional drag force on said fibers; split-ting said array into a plurality o bundles of fibers; modifying the drag force between said array of fibers and said contact surface to produce a second frictional drag force; and collecting said bundles of fibers. Preferably said first frictional drag force is greater than said second frictional drag force.

Accordin~ to another aspect of this invention there is provided apparatus for collecting an array of fibers comprising a contact surface arranged to be contacted by said array of fibers to produce a frictional drag force on said fibers; splitter means for dividing said array into a plurality of bundles of fibers; means for modifying said frictional drag force; and means for collecting said bundles of fibers. Preferably said contact surface is an applicator surface.
An increase in the frictional drag force applied to the fibers as they contact the applicator surface increases the tension of the fibers in the array and reduces the "dancing"
effect referred to above, makes insertion of the splitter easier, and allows the array to be divided into bundles o nearly equal size. The fibers, under the influence of the increased drag force have a tendency to assume the alignment of the source of the array of fibers. For example, fibers pulled from a fiber-forming bushing will, under increased drag force, be more disposed to assume an alignment at the contact surface which corresponds to the alignment of fibers at the bushing.
In its most preferred embodiment the contact surface is a rotating surface and the frictional drag force is modified by changing the speed of rotation of the surface. In alternative embodiments the frictional drag force is modified by changing the ;
amount of a lubricant applied to the contact surface, or by changing the area of contact between the array of fibers and the contact surface.
The method and apparatus of this invention are particularly suitable for the handling of an array of glass fibers, especially glass fibers drawn from a fiber~forming bushing.

1(~ 4 The invention will be further understood from -the follow-ing description by way of example oE embodiments thereof with reference to the accompanying drawings, in which:
Figure 1 is a front elevation view and Figure 2 is a side elevation view of a fiber-forming bushing and fiber array handling apparatus, the two figures illustrating different embodiments Qf this invention, and Figure 3 is a plan view o a splitter shown in Figures 1 and 2.
Referring to the drawings, there is shown a bushing 10 comprising a chamber for holding glass mass 12. The chamber has orifices 14 through which glass is emitted and attenuated into fibers 16 in the form of an array.
The array of fibers is passed in contact with a contact surface 18, thereby creating a frictional drag force on the fibers. Below the contact surface the fibers are contacted by a gathering member 20 which is suitable for gathering the fibers into a strand. The strand is collected on a rotating collet 22 of a conventional winder 24.
In order to divide thP array of fibers into bundles of fibers, a splitter 26 is inserted into the array. The splitter can be inserted manually. The comb-like splitter, shown in Figure 3, has projections to maintain separation between fiher ~ -bundles. It is usually desirable to divide the array evenly to obtain bundles containing substantially equal numbers of fibers.
Subsequent to the splitting, the bundles of fibers can be com-bined to form a single strand, as shown in Fi~ures 1 and 2, or they can be collected while the separation between bundles is `
maintained.

~3-~0t;4884 One method which can be used to modify the drag force exerted by the contact surface from a first drag force to a second drag force is to make the contact surface 18 rotatable and to rotate the contact surface at different speeds. For example, in a typical fiber forming and collecting operation, a rotating size applicator surface is utilized to contact the fibers and apply a size. By changing the speed of rotation of the applicator surface, the drag force on the fibers is modified. The rotation of the applicator surface can be 10 accomplished by means of a variable speed motor 30 as shown in ~ ' Figure 1.
In another embodiment of this invention the frictional drag force applied to the fibers by the contact surface is mod- ;
ified by changing the amount of a lubricant applied to the ~`~
contact surface. An increase in the amount of lubricant decreases ~,~
the drag force on the fibers. For example, as shown in Figure 2, lubricant 32 flows from a reservoir 34 through a conduit 36 and onto the contact surface 18. A valve 38 controls the amount of lubricant deposited. In a typical fiber forming and collecting 20 operation, a size is applied to the fibers at the contact sur- ~
face, and the size acts as a lubricant. - ;
It is to be understood that the contact surface can be a rotatable size applicator of the type in which the rotating sur-face contacts a size reservoir to become coated with a size and in which increasing the speed of rotation results in an increase in the amount of size coating the applicator surface. Thus, the drag force from such an applicator can be reduced by increasing the rotational speed of the applicator; this results in an increase in the amount of size coating the applicator surface.

.. .. . . . . .. . . . .
. ,. : : .. . . -3~ 4 In another embodiment of this invention, the frictional force applied to the fibers by the contact surface is modified by changing the amount of con-tact between the fibers and the contact surface. If the contact surface is curved, as shown in Figure 2, this can be accomplished by increasing the angle of wrap of the fibers around the curved surface. For example, movement of the gathering member 20 along the path indicated by the arrows in Figure 2 has the ef*ect of modifying the wrap angle at the contact surface. As the gathering member in Figure 2 is moved to the right, the wrap angle increases, thereby increasing the drag force and producing a more uniform ; alignment of fibers in the array. It is also possible for the contact surface to be moved to change the amount of contact between the fibers and the contact surface.
It will be evident that various other modifications can be made without departing from the scope of the invention as defined in the claims.
