Abstract
Provided are a process and an apparatus for producing a fiber-reinforced thermoplastic resin tape, the process and the apparatus being capable of preventing fiber cut from occurring at the start of production of the fiber-reinforced thermoplastic resin tape. The provided process includes a resin impregnation step of opening a fiber bundle and impregnating the fiber bundle with molten thermoplastic resin and a through-nozzle passing step of passing the fiber bundle having undergone the resin impregnation step through a slit formed in a nozzle. The through-nozzle passing step includes setting, at the start of production, a gap dimension of the slit to a dimension larger than a normal dimension and changing the gap dimension of the slit to the normal dimension when a predetermined condition is satisfied, after the production start.
