  • Package of tape type non-twisted carbon fiber bundle
    Patent number: 5499776
    Abstract: A take-up apparatus for tape type non-twisted carbon fiber bundles, in which a traverse guide unit consists of an introduction guide roller disposed so that an angle .theta..sub.1 between the introduction guide roller and the axial direction of the bobbin is substantially 90.degree., a final guide roller disposed so that an angle .theta..sub.e between it and the axial direction of the bobbin is -5.degree..+-.10.degree.(i.e., -15.degree. to +5.degree.), and at least one intermediate guide roller disposed between the introduction guide roller and final guide roller so that an angle difference between an intermediate guide roller and an adjacent guide roller is not more than 45.degree.. A take-up apparatus is also disclosed for tape type non-twisted carbon fiber bundles, in which a traverse guide unit has a helically continuing curved guide surface, an initial portion, i.e.

  • Yarn package of carbon filament yarn
    Patent number: 4586679
    Abstract: A package of carbon filament yarn having no slipover tendency upon unwinding thereof, in which a yarn trace formed by a traverse is repeated every n cycles at a predetermined shifting ratio in a range of 50% to 150% relative to the yarn width, n being a positive integer of not more than 9. The package can be obtained by using a conventional spindle drive winder under a selected winding ratio and winding tension.
