Claim:
A hair-transplanting apparatus, comprising: a first supplying unit for supplying a base sheet of elastic material to a predetermined position; a base stretching unit for stretching said base sheet at said predetermined position; a second supplying unit for supplying a hair segment of a predetermined length to a first side of said base sheet; at least two reciprocating needles with hook ends having an original position below a second side of said base sheet, said needle hook ends piercing said base sheet to form holes and reaching beyond said first side of said base sheet during ascending movement of said needles, said needle hook ends catching an intermediate portion of said hair segment at said first side of said base sheet and then passing down through said holes to reach beyond said second side of said base sheet so that said intermediate portion of said hair segment caught by said hook ends remains on said first side of said base sheet, whereas a pair of lengthwise hair extensions extending from opposite sides of said intermediate portion pass through said holes to below said second side of said base sheet; a hair-curling unit for giving a shape-retainable turn at said intermediate portion of said hair segment which has been caught by said hook ends of said needle on said first side of said base; a first adhesive applicator for applying first adhesive to each of said turns of said hair segments remaining on said first side of said base sheet, thereby forming a first adhesive layer each surrounding said turn; and a second adhesive applicator for applying a second adhesive to all over said first side of said base sheet, including said first adhesive layers, to form a second adhesive layer; said needle, said hair-curling unit and said first adhesive applicator being operable while said base sheet is maintained stretched by said base stretching unit, said stretched condition of said base sheet being released or loosened after a predetermined number of said hair segments are transplanted to said base sheet by said needles and secured thereto by said first adhesive layers, followed by forming said second adhesive layer by said second adhesive applicator.
