Patent ID: 7255302

Claim:
A guide apparatus for guiding an advancing continuous fiber bundle used when winding the fiber bundle on a bobbin, which comprises: a first guide and a second guide, each of said guides being disposed in a passage through which the fiber bundle is advanced, wherein axis lines of the first and second guides are twisted away from each other in a space, and a parallel guide, which is disposed at a downstream side of the first and second guides on the passage, through which the fiber bundle is guided to the bobbin and which has an axis line parallel to that of the bobbin, a first fixed guide roll, which is disposed at an upstream side of the first guide on the passage, and which supplies the fiber bundle as a state that a direction of a width of the fiber bundle is parallel to a bobbin axis, the first guide comprising a substantially flat guide, which guides the fiber bundle in a twisted state, and which has the axis line thereof arranged so as to cross substantially at a right angle to that of the bobbin, between the first fixed guide roll and the first guide, the direction of the width of the fiber bundle is twisted from a state that the direction of the width of the fiber bundle is parallel to the bobbin axis to a state on the first guide that the direction of the width of the fiber bundle is at a right angle to the bobbin axis, the second guide comprising a conical guide on which the fiber bundle is advanced in a twisted state, on said parallel guide, the fiber bundle being twisted back to the same direction as the direction of the fiber bundle when being supplied from the first fixed guide roll, or being twisted further in the same direction to thereby turn the fiber bundle upside down, wherein the position at which the fiber bundle is wound on the bobbin and the width of the fiber bundle are stabilized by means of said parallel guide.
