Abstract: A pair of flanges (12, 12) which have through-holes (17) for a rotating shaft, and a shaft part which connects the central parts of these flanges (12, 12) at a specified spacing, are formed from cardboard plates; furthermore, the above-mentioned shaft part is formed so that this shaft part is foldable. For example, flaps (13) which extend in the radial direction, and which have base ends (13a) on the side of the central part of the corresponding flange (12) are formed by stamping in each of the pair of flanges (12, 12) and slits (14) which extend in the circumferential direction of each flange (12) are formed on a circle that is concentric with the flange (12), and which includes the base ends (13a) of the flaps (13). The flaps (13) of the respective flanges (12) are pulled into upright positions, and the projecting parts (13b) of the flaps (13) of one of the flanges (12) are inserted into the slits (14) of the other flange (12), thus fastening the flanges (12) to each other, so that a reel (11) is formed.

Abstract: The invention provides an embossed carrier tape molding and sealing apparatus which is devised so that the molding of the embossed carrier tape and the sealing of electronic parts can be efficiently performed.
