Definitions

  • the present invention relates to a method of and an apparatus for forming glass fibers and it has particular relation to apparatus for automatically drawing a plurality of continuous glass filaments from a molten bath,
  • a plurality of glass filaments are drawn through orifices in an electrically heated, platinum alloy bushing and gathered together in the form of a strand.
  • the strand is wound upon a forming tube mounted on a rotating cylinder called a collett.
  • the traversing means will move the strand through a 3 inch throw as it is wound on the forming tube.
  • the traversing means' is axially reciprocated relative to the forming tube in order to wind the strand throughout a substantial portion of the length of the forming tube which may be 8 or more inches in length.
  • an operator pulls the individual filaments from the bushing by hand and groups them into a strand.
  • the strand is passed over a gathering guide and is wound around one end of the collett beyond the forming tube. Rotation of the forming tube is then begun. It takes several seconds for the forming tube to come up to the proper drawing speed and during this time the strand which is wound on the collett is of too great a diameter.
  • the strand which is formed during the start up is wound in a small area at the end of the collet and is held in this position by the operator.
  • the traverse is started and the strand is shifted by the traverse lengthwise of the tube so as to be wound during the remainder of the run in an area on the tube which is spaced from the strand formed during the start up on the end of the collett.
  • the strand is led back to the end portion of the collett containing the strand formed during start up and wound thereon as the forming tube rotation returns to zero.
  • all of the oif size strand is located at one place on the collett and off of the forming tube. The off size strand is cut from the collett and is discarded before the forming tube is removed from the collett.
  • the open wind is such that the strand is traversed the length of the tube for a relatively few turns of strand on the tube, i.e., 2 to 5 or more turns for a 7 to 10 inch long package for each traverse of the length of the tube. With this type of wind the succeeding turns of strand cross each other ata minimum angle of at least 5.

  • the collett motor 60 was first started to rotate collett 19am then aftera delay through timer lTR and its contact lTR-l, the valve 128. was opened to initiate the movement of carriage '34 toward the outermost position. Because timer3TR is initiated at the time Y that sole'noid SV-l is energized, the timer STR'after its delay (about 1 'to 2'seconds) closes anorinally open contactSTR-l of the on-del'ay type. .Thus, after a short delay'the'coil 2M of the starter relay for traverse motor 1'16 is energized to begin rotation of the traverse. With this arrangement the traverse does not begin to rotate until the on-size strand is being wound on the forming tube.
  • synchronous motor timer -4TR is energized, because timer 4TR is in parallel with coil 2M and'in series 'with contact 3TR1.'- This timer is set for the length of the run, for example, 10 minutes.

The carriage 34 will continue past the position defined by poppet valve 154 to its innermost position.
  • the solenoid 'B was energized by the closing of contact 1M-3 in series with the solenoid- B upon the energization'of coil 1M.
  • a coil PC of a plugging relay for motor is energized to provide a reversing torque for collett motor 60 so that the rotation'of motor 60 and collett 19 decreases.
  • the relay containing coil PC at this time closes a normally open contact PC-2 in parallel with contact 1M-3 and inseries with solenoid B so that the energization of solenoid B continues during plugging of motor 60.
  • the coil PC is in series with normally closed contact lM-l and'a normally open contact 2TR-1 of time delay relay 2TR.' Upon the energization of coil 2TR during start up of operations, contact 2TR- 1 was closed. As a result, coil PC is energized through the closing of contact lM-l upon the de-energization of coil 1M. However, the 'de-energizati-on of. coil 1M that opens contact IM-2 for de energization of solenoid SV-1 also deenergizes'coil 2TR so that contact 2TR-1 opens after its delay of about 5 seconds to de-energize coil'PC. This stops the reversing torque and at the same time de-energizes solenoid B so that the brake moves into its brak ing position. With this arrangement the braking is accomplished only after the spindle has been reduced to a slow speed of rotation.
  • the collett By holding the motor spindle in fixed position, the collett in turn is held steady at the end of therun. This facilitates the removal of the off-size strand from the end of the collett and the removal of the forming tube from the collett. 'The operator cuts the ofi-size strand from the collett prior to the removal of the forming tube and; this canbe done more easily without danger of the operator cutting himself during the severing'of the strand.
  • the forming tube can bere'moved' and a new one in- 9 serted on the collett more easily when the collett is held stationary.
  • the contact FS-Z is closed and a fiber forming run as described above is ready to begin again. If the operator wishes to discontinue the fiber forming operation and not start a new run, the manual stop button PB-l can be pressed rather than the foot switch at the end of the run.
  • the winding operation may be made completely automatic by relocating the contact 4TR-1 to be in series with the stop button PB-1 instead of as shown and described.
  • the collett is stopped and moved to its innermost position at the end of the run automatically rather than requiring the operator to depress the foot switch to stop the fiber forming operation. It is preferred, however, to have the operator stop the fiber forming run rather than have it automatically stop for several reasons. If the operation is stopped automatically, glass which is extruding slowly from the bushing orifices may fall on to the finished package and ruin it.
  • the molten glass may also fall on to the winding equipment and cause some damage to it. Also, automatically stopping the operation at a given time eliminates the formation of good strand on the forming tube during the short interval of time that is required for the operator to see the light and stop the run, thereby reducing production by a certain small percentage.
  • a method of forming a glass fiber strand which comprises drawing a plurality of individual glass filaments from a source of glass, applying a size to the glass filaments, passing them through a stationary guide to group them into a strand, wrapping the strand in substantially parallel relation around one end of a cylinder while the cylinder is located in a first position, commencing rotation of the cylinder, increasing the rotation of the cylinder to a desired speed, thereafter moving the cylinder axially to a second position so that the strand is wound around the other end of the cylinder, engaging the strand at one location intermediate the guide and the cylinder after the axial movement of the cylinder from the first to the second position has begun to impart a slight traversing movement to the strand as it is wound on the rotating cylinder, reversing the axial movement of the cylinder to cause the cylinder to move axially to a third position intermediate the first and second positions, axially reciprocating the rotating cylinder between the second and third positions while imparting a slight traverse to the strand being wound upon the
