1. A fiber width adjustment device for adjusting a width of a tape made of fibers before or after being impregnated with resin, the tape being a material for a fiber reinforced plastic,
the device comprising:
a pair of wall surfaces forming a path for passing the tape, the path having a gradually decreasing width;
a moving mechanism, including a motor and a rotating shaft rotated by the motor, configured to move the path relatively to the tape so that a position at which the tape leaves the path changes; and
rollers, for feeding the tape, in the path.
