ABSTRACT:
A take-up apparatus is disclosed 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. an introduction surface portion of the curved guide surface extending at substantially right angles to the axial direction of a bobbin, and a final portion, i.e. discharge surface portion of the curved guide surface extending at an angle in the range of -5.degree..+-.10.degree. with respect to the axial direction of the bobbin.
