Definitions

  • the present application relates generally to apparatuses and processes for manufacturing reinforcing fibers, and in particular, for cutting mineral and carbon fibers by way of a vibrating cutting device.

  • the apparatus further comprises a coating applied to the fibers, wherein the vibration of the cutting implement heats the coating to bind the cut fibers together.
  • the fibers comprise glass fibers.
  • the fibers comprise carbon fibers.
  • the fibers have a diameter of about 10 micrometers to about 14 micrometers.
  • the fibers are cut by the cutting device while moving at a linear speed of about 900 meters per minute to about 1,800 meters per minute.
  • a process for manufacturing cut fibers comprises cutting fibers (202, 302) into cut fibers (204, 304); and collecting the cut fibers with a collecting device (230, 330); the improvement characterized in that the fibers are cut with a cutting device (220, 340) that comprises: an anvil (222, 342); a cutting implement (226, 346) having a plurality of cutting edges (227, 347) for pressing the fibers against the anvil; and an ultrasonic vibration source (228, 240, 348, 350) for vibrating the cutting implement to cut the fibers, wherein the ultrasonic vibration source has a frequency of about 20 kHz to about 40 kHz, wherein the ultrasonic vibration source has an amplitude of about 10 micrometers to about 30 micrometers, and wherein the cutting device cuts the fibers transversely, across a direction of travel (201, 301).
  • the cutting implement is a cutting wheel
  • the ultrasonic vibration source (240, 350) is arranged on an axis of rotation (241, 351) of the cutting wheel.
  • the process further comprises binding the cut fibers together through heating a coating applied to the fibers with the cutting implement.

  • Figure 6 shows an exemplary manufacturing line for manufacturing cut fibers
  • Figure 7 shows an exemplary manufacturing line for manufacturing cut fibers
  • Figure 9 is a perspective view of the cutting wheel of Figure 6;
  • Figure 11 is a perspective view of the cutting wheel of Figure 6 attached to an ultrasonic vibration source.
  • interconnection may be direct as between the components or may be indirect such as through the use of one or more intermediary components.
  • reference to a “member,”“component,” or“portion” shall not be limited to a single structural member, component, or element but can include an assembly of components, members, or elements.
  • the terms“substantially” and“about” are defined as at least close to (and includes) a given value or state (preferably within 10% thereof, more preferably within 1% thereof, and most preferably within 0.1% thereof).
  • Reinforcing fibers such as mineral fibers (e.g., glass fibers) and carbon fibers, may be manufactured and processed as long bundles or ribbons of fibers on a continuous manufacturing line.
  • the ribbons of fibers may be collected onto a spool of material to be transported to another location for further processing (i.e., offline processing) or may be processed on the same line in which the fibers were made (i.e., inline processing).
  • the bundles of fibers may be cut longitudinally, i.e., along the length of the bundle of fibers, to create a narrower bundle having the same length.
  • the bundles of fibers may cut transversely, i.e., across the bundle of fibers, to form many shorter fibers. In either case— longitudinal or transverse cutting— the cutting process performed continuously without removing the fibers from the manufacturing line.
  • the fibers may travel down the manufacturing line at a high linear speed of about one or more tens of meters per second.

  • the ultrasonic vibration source causes the cutting implement 110 to move back and forth between a cutting direction 112 (Fig. 2) and a retreat direction 114 (Fig. 3).
  • the movement of the cutting implement 110 shown in Figures 2-5 is exaggerated to better illustrate the movement of the cutting implement 110 toward and away from the bundle of fibers 102. As the cutting implement 110 is advanced through the bundle of fibers 102, the cutting implement 110 rapidly cycles between impacting and retreating from the fibers 104.
  • the cutting implement 110 breaks through fewer fibers 104 with each impact and less force is needed to cut through the entire bundle of fibers 102.
  • secondary fractures are reduced or eliminated when the fibers 104 are cut with the vibrating cutting implement 110.
  • the cutting implement 110 experiences less wear and lasts longer between maintenance cycles.
  • the anvil (not shown) that supports the bundle of fibers 102 during cutting is exposed to less stress during cutting so that wear on the anvil is reduced.
  • the oscillating movement of the cutting implement 110 during cutting of the fibers 104 generates heat from friction that can melt or fuse coatings applied to the fibers, e.g., sizing, or the fibers themselves to bind the fibers 104 together. Binding the fibers 104 together at the same time as the fibers 104 are cut or broken produces a relatively smooth cut edge of the bundle of fibers 102.
  • the manufacturing line 200 includes a supply 210 for supplying fibers 202 to a cutting device 220. Cut fibers 204 are collected in a collecting device 230 after being cut by the cutting device 220.

  • manufacturing line 200 may optionally include one or more guiding devices 212 for aligning the fibers 202 prior to processing by the cutting device 220.
  • the manufacturing line 200 may also include a fiber production apparatus (not shown) for producing the fibers 202 directly from raw material, rather than a supply 210 of previously manufactured fibers.
  • the fibers 202 are cut transversely by the cutting device 220 into shorter cut fibers 204 having a predetermined length.
  • the fibers 202 are cut between an anvil wheel 222 and a cutter 224.
  • the cutter 224 includes a cutting implement or wheel 226 and an ultrasonic vibration source 228.
  • the peripheral surface of the cutting wheel 226 includes a plurality of cutting edges 227.
  • the cutting wheel 226 presses the uncut fibers 202 against the anvil wheel 222 so that the cutting edges 227 engage and chop the fibers 202 into shorter, cut fibers 204.
  • a pressing wheel 221 may optionally be included to retain the uncut fibers 202 against the anvil wheel 222 prior to cutting.
  • the cutting wheel 226 and anvil wheel 222 can be made from any suitable material, such as, for example, tungsten carbide, polycrystalline diamond, aluminum alloys, tool steel, and titanium alloys.

  • the anvil wheel 222 can include a coating formed from a smooth elastomeric material, such as polyurethane, to improve the wear resistance of the anvil wheel 222.
  • the coating may be about 1 millimeter to about 5 millimeters thick and have a hardness of about 85 ShA, about 95 ShA, or about 67 ShD.
  • the cutting wheel 226 has an outer diameter of about 90 millimeters to about
  • the cutting edges 227 are spaced about 3 millimeters apart, about 4.5 millimeters apart, about 6 millimeters apart, about 9 millimeters apart, about 12 millimeters apart, about 24 millimeters apart, or about 50 millimeters apart.
  • the cutting wheel 226 includes as few as five cutting edges 227 and as many as ninety-five cutting edges 227.

  • the cut fibers 304 can be gathered on separate spools 332.
  • the cut fibers 304 are collected on a single spool.
  • the manufacturing line 300 may optionally include one or more guiding devices 312 for aligning the bundle of fibers 302 prior to processing by the cutting device 320, 340.
  • Bundles of fibers 302 are continuously supplied from the supply 310 and are moved in a direction of travel 301 through the manufacturing line 300.
  • the supply 310 may be a roll of reinforcing fibers or may be the end of another manufacturing line (not shown) that forms bundles of fibers 302 from raw materials, such as glass, carbon, or any other suitable material.

  • the bundle of fibers 302 is cut longitudinally by the cutting device 320, 340 into narrower ribbons of cut fibers 304 having a predetermined width.
  • individual fibers or filaments of the bundle of fibers 302 may not be broken but merely spread apart by the cutting device 320, 340 to form the narrower bundles or ribbons of cut fibers 304.
  • Some individual fibers are cut, however, because the individual fibers are not perfectly aligned in a longitudinal direction, i.e., with the direction of travel 301.
  • the fibers 302 are cut between an anvil wheel 322 and a cutter 324.
  • the cutter 324 includes a non-rotating or static cutting implement 326 and an ultrasonic vibration source 328. As can be seen in Figure 10, the peripheral surface of the anvil wheel 322 includes a plurality of cutting edges 323. The cutter 324 presses the uncut fibers 302 against the anvil wheel 322 so that the cutting edges 323 engage and cut or split the bundle of fibers 302 into narrower bundles of fibers 304.
  • the cutting implement 326 is vibrated by the ultrasonic vibration source 328 so that the fibers 302 are cut in an opposite manner as is described above with regards to Figures 2-5. That is, the fibers 302 are moved toward cutting edges 323 of the anvil wheel 322 rather than moving the cutting surface 323 toward the fibers 302. Because less force is needed to cut through the fibers 302 when the cutting implement 326 is vibrated
  • the anvil wheel 322 and cutting implement 326 require less maintenance than a non-vibrating cutter.

  • the anvil wheel 322 has a width of about 40 millimeters to about 50 millimeters, or about 45 millimeters.
  • the cutting device 320 includes two or more anvil wheels 322 axially aligned to create a cutting area width of about 80 millimeters to 100 millimeters, or about 90 millimeters.
  • the cutter 344 presses the uncut fibers 302 against the anvil 342 so that the cutting edges 347 engage and cut or split the bundle of fibers 302 into narrower bundles of fibers 304.
  • the anvil 342 is an anvil wheel like the anvil wheel 222 described above and shown in Figure 6.
  • the cutting edges 347 of the cutting wheel 346 are vibrated by the ultrasonic vibration source 348 so that the fibers 302 are cut as described above with regards to Figures 2-5. Because less force is needed to cut through the fibers 302 when the cutting edges 347 are vibrated ultrasonically, the cutting wheel 346 and anvil 342 require less maintenance than a non-vibrating cutter.
  • the cutting wheel 346 and anvil 342 can be made from any suitable material, such as, for example, tungsten carbide, polycrystalline diamond, aluminum alloys, tool steel, and titanium alloys.
  • the cutting wheel 346 can optionally be provided with a surface treatment to increase hardness and wear resistance.
  • the anvil 342 can include a coating formed from a smooth elastomeric material, such as polyurethane, to improve the wear resistance of the anvil 342.

  • the cutting wheel 346 has an outer diameter of about 90 millimeters to about
  • the cutting edges 347 are spaced about 3 millimeters apart, about 4.5 millimeters apart, about 6 millimeters apart, about 9 millimeters apart, about 12 millimeters apart, about 24 millimeters apart, or about 50 millimeters apart.

  • the cutting wheel 346 has a width of about 40 millimeters to about 50 millimeters, or about 45 millimeters.
  • the vibrations cause the cutting wheel 226, 346 to expand and contract axially. Because the mass of the cutting wheel 226, 346 is not changed, the cutting wheel 226, 346 expands radially in response to the axial compression, and retracts radially in response to the axial expansion. Thus, the vibrations are transmitted radially throughout the entire cutting wheel 226, 346 and to each cutting edge 227, 347, simultaneously.
  • a process for manufacturing cut reinforcing fibers includes steps of supplying fibers from a supply of fibers to a manufacturing line that moves the fibers in a direction of travel, cutting the fibers drawn from the supply with a cutting device, and collecting the fibers with a collecting device.
