    TECHNICAL AND APPARATUS FOR APPLYING A SIZING COMPOSITION TO GLASS FIBERS}
    [2] Glass fibers are used in various technical fields. Glass fibers are generally applied as reinforcements in polymer matrices to form glass fiber reinforced plastics or composites. The manufacture of the glass fibers begins by providing molten glass to a heat resistant platinum tray called " bushing. &Quot; The bushing has a plurality of orifices, through which molten glass flows into a filament. The filaments are then applied in an aqueous or non-aqueous size through an applicator roll. The size applied to the filament acts as a polymer reinforcement by protecting the filament during processing and handling and assuring adhesion of the glass filament to the resin material. Finally, after the size has been applied, the filaments are collected together into strands, known as gathering shoes, and wound in a collet to form a glass fiber package.
    [3] U. S. Patent No. 4,537, 610 discloses an applicator for applying a non-aqueous sized composite to glass fibers. The applicator includes a driven roll, which receives the size from the chamber and applies this size to the surface of the glass fiber being drawn out. One common problem with applicators with driven rolls is "fiber wrap". This problem occurs when the fibers are attached to the surface of the size- buried driven roll and wrapped around the roll. This problem is costly because the fiber forming process stops as a result.

The glass forming process 10 shown in FIG. 1 includes a bushing 12 with a plurality of orifices (not shown) through which the flow of a plurality of molten glass is discharged. The orifice may be extended by hollow studs or tips (not shown). The flow of glass is mechanically drawn by winder device 116 to form continuous fiber 14. Instead of the winder device 116, a conventional chopper (not shown) can be used. The fiber 14 passes through a size applicator 30 that applies a uniform coating of the size composite to the fiber 14. The size composite applied by the applicator 30 is generally a non-aqueous system, but other It may be of the appropriate kind.

Motor 420 is operated by a switch (not shown) provided to motor 420. Alternatively, the splitting mechanism may comprise a manually actuated crank mechanism instead of a motor to effect rotation of the main body portion 34.
    [23] The applicator element 32 is rotatably positioned such that the insert of one of the inserts 36a, 36b is in contact with the reinforcing fiber 14 drawn downward by the winder device 116. 1 and 2, the first insert 36a is shown positioned in the path of the moving fiber 14. Once the insert 36a is worn, the split mechanism 400 is actuated by a switch for a time sufficient to rotate the main body portion 34 by about 180 °, whereby the second insert 36b moves the moving fiber 14. Is located in the path. Rotation of main body portion 34 may occur during fiber forming operations. Thus, when one of the inserts 36a and 36b is worn out, it is not necessary to stop the fiber forming operation in order to replace the worn insert. Rather, the main body portion 34 is rotated during the fiber forming operation so that a new insert is positioned in the path of the moving fiber 14. Thereafter, the worn insert opposite the insert in contact with the moving fiber 14 is replaced with a new insert.

For reuse of the captured size composite, a body 56 is provided inside the reservoir 52 for filtering contaminants from the captured size composite.
    [27] The size source 50 also includes first and second level sensors 58a and 58b, as shown in FIG. The two level sensors 58a, 58b may comprise one of a number of commercially available sensors for detecting fluid, such as a fluid level switch sensor, one of which is the trade name "BLS- 7 (L007011) "is commercially available from Barksdale. The sensor 58a detects when the level of the size composite in the reservoir 52 reaches the first predetermined level as indicated by the dotted line 59a in FIG. 2, and the sensor 58b stores the reservoir ( It is sensed when the level of the size composite in 52) falls below the second predetermined level as indicated by the solid line 59b.
