<p>PROBLEM TO BE SOLVED: To provide a method for bonding a decoration made of celluloid at a time, without piecing it out with another, to a string-instrument body part with a circumference exceeding 170 cm along the periphery thereof. SOLUTION: Two celluloid sheets 7a, 7b several centimeters wide, whose total length is made somewhat longer for jointing them together, are formed so that they can be combined with each other by using trapezoidal projection parts and longitudinally adjoining trapezoidal recess parts provided as joint portions. The celluloid sheets 7a, 7b are jointed to each other by means of an adhesive, etc., to form a celluloid sheet of a prescribed length (170 cm or more), and it is slit into narrow and long celluloid sheets 7 each having a width of about 6 mm.</p> |
