  • This invention relates to a method of and a plurality of parallelograms whose major and means for orienting strand material, and more minor axes may readily be changed by elonga particularly to a method of and means for iorienttion of the cross bar structure.
  • Extending from ing glass filaments. beneath the cross bar structure are a plurality of Inair conditioning equipment of the type illusdependi'ng'fingers or pins, which may constitute 5 trated in U. S. Patent No. 2,054,809, backets filled extensions of the pins joining the cross bar memwith oriented glass filaments or the like, are used. bers and/or extend from the cross bars.

Due to the tendency of the thereof.
  • the operation may be repeated if a siderable effort has been directed toward the atgreater degree of orientation is desired and/or tainment of this end; and in order to accom-. to insure a more uniform distribution and plish such orientation, it has been necessary arrangement of the filaments in the finished manually to manipulate the filaments.
  • This repetition may be accomplished 25 operation is both expensive and slow, and not by using the same cross bar structure over again conducive to the inexpensive production" of ,or bypassing the-filaments to be acted upon by oriented glass fibers or the like in substantial a second cross bar structure. This latter method volume.
  • the general object of the present invention is handled upon a conveyor belt or the like, as is 30 to provide an improved method of and means for customary inlarge scale production.
  • FIG. 40 Another object of the invention is to provide to be read in connection with the accompanying 40 an improved method of and means for orienting drawing, in which glass filaments or the like, which render the Fig. 1 is a diagrammatic elevational view of orientation of glass filaments both rapid and the invention as applied tothe orientation of inexpensive. strands being moved upon a conveyor belt;

  • the pins are relatively loose lowering of the cross bar structure.
  • the numeral 5 desig- 55 nates a conveyor belt carried upon rollers 6 and adapted to be driven by drive roller 1.
  • Drive roller 1 is driven by motor 8, or the like, through gears 9, and drive shaft Ill.
  • Glass strands or filaments H are deposited upon the belt 5, as indicated at H and form a heterogeneous mass upon the surface of belt 5. Due to the motion of the conveyor belt the thickness of the heterogeneous mass is desirably limited, but the filaments which comprise this mass lie in all directions, although most of the filaments will lie in planes substantially parallel to a common plane. In order to effect orientation of these filaments. the apparatus generally designated I2 is employed.
  • the glass filaments may be passed through an annealing chamber l3 and upon their emergence therefrom will be ready for use.
  • the apparatus l2 orients the filaments before they are supplied to the annealing chamber l3, but it is to be understood that the orientation may be ac.- complished subsequent to. the annealing step if such operation is preferred.
  • any desired number of orienting devices such as l2, may be provided and used, and these may be adapted to act upon the filaments prior and/or subsequent to the annealing step, the number of these devices which is employed depending upon th degree of orientation and/or the uniformity of the product which is desired.
  • a binder preferably of the watersoluble type, may be sprayed uponthe filaments after they have been oriented to the desired degree, in order that they may readily be handled as they reach the end of theconveyor belt, and to facilitate their packing and shipment.
  • the cross bar lattice of device I2 comprises a plurality of cross bars l4 parallel to each other and a plurality of cross bar members M parallel to each other, these two sets of cross bars beingin superposed relation. Bars II! and are pivotally connected together at any desired number of points, by pins l extending therethrough.
  • the lattice may be elongated and con-' tracted along the line of travel of the belt 5.
  • a plurality of fingers or pins IB may constitute extensions of the pins l5 which pivotally connect the members M and H'
  • pins i6 may depend from the bars l4 and N at points intermediate of the points of interconnection between these bars.
  • the cross bars are constituted coarse combs.
  • Support i I is attached to the lattice, preferably at the central portion thereof as indicated at l8, in any suitable, manner, as by the collars l9.
  • Support IT is adapted to 'move up and down within the guides 20 which insure its travel in a vertical direction.
  • Support I! is moved upwardly and downwardly by cam 2
  • carriedon shaft 22, which is driven preferably by motor 8.
  • is preferably of V the cored type in which a groove 23 is formed. The path of this groove within the cam determines the vertical movement of the support II, which is secured, as by arm 24, to roller 25 disposed within the groove 23.
  • control rods 26 Pivotally connected to the extremities l5 of the lattice, preferably to the tops of the pins l5 connecting the members l4 and N at these points, are control rods 26, adapted to control the elongation and contraction of the lattice.
  • the other ends of control rods 26 are pivotally connected, as at2l, to a collar 28 slidably carried on support I1.
  • Collar 28 is connected by extension 29 to a. roller or the like, 30, disposed within the groove 3i of cam 32.
  • Cam 32 is carried on and rotated by shaft 22, and thus the elongation and contraction of the lattice is in timed relation with the movement of glass filaments on the conveyor belt and in timed relation with the up and down movement of the lattice.
  • and 32 are so formed and arranged that the lattice is lowered in contracted condition upon the mass of filaments to be oriented, so that the pins l6 depend ng from the lattice extend into the mass of filaments; so that while the lattice is inlowered position it is elongated by a downward movement of collar 28, whereby the at each downward motion, it will be understood that the lattice device I! may be used to act upon a batch of material more than once before this batch of material is moved from beneath the device l2 by the conveyor belt. Furthermore, where such repeated operation is provided, the apparatus may be so arranged that successive elongations of the lattice are progressively greater.
  • the lattice may be contracted slightly after its elongation and while its pins are still within the filamentous mass, in order to facilitate removal of the pins and raising of the lattice.
  • the device l2 and the conveyor belt 5 have been illustrated and described as being mechanicallyconnected and driven by the same prime mover, it will be understood that they may be driven by diiferent prime movers, and that the device l2may be manually driven, instead of mechanically driven, if desired.
  • the lattice has been described as being lowered upon the filamentous mass, if desired, the lattice may be formed with upwardly extending pins, the filamentous mass in such case being placed upon the lattice.
  • the conveyor belt, work table or the like along'which the glass travels may be formed with suitable openings so that the pins of the lattice may extend upwardly through these openings and into the filamentous mass, the lattice being placed beneath the conveyor belt or work table and the control being the reverse of that hereinbefore described.
