Fiber structure manufacturing apparatus

A fiber structure manufacturing apparatus, comprising:

• a defibrated material supplying unit that supplies a defibrated material obtained by defibrating a material that contains fibers;
• a resin supplying unit that supplies resin fibers;
• a mixing unit that produces a mixture by mixing the defibrated material with the resin fibers;
• an accumulation unit that produces an accumulated material by causing the mixture to accumulate;
• and
• a shape molding unit that produces a fiber structure by performing shape molding of the accumulated material, wherein
• the resin supplying unit includes
• a fragmenting unit that produces resin fiber fragments by performing fragmentation of a cotton-like lump of the resin fibers,
• a constant amount supplying unit that supplies a constant amount of the resin fiber fragments produced by the fragmenting unit,
• a loosening unit that loosens the resin fiber fragments supplied from the constant amount supplying unit to decrease density of the resin fiber fragments, and
• a transferring unit that transfers the resin fibers like a cotton loosened by the loosening unit to the mixing unit.
