Zusammenfassung:PURPOSE:To obtain an embossed carrier tape having a uniform side wall and no deformation of a bottom by vacuum sucking and corresponding to small electronic parts to be mounted by a method wherein a mold is shaped into a projected form and has an outer dimension consistent with the inner dimension of a pocket. CONSTITUTION:On the outer periphery of a center rotating drum 8 of a rotating drum 5, projected maids 6 for molding pockets are arranged at fixed intervals. In rotating drums 7, 9 disposed on the both sides thereof, slits 10 for vacuum sucking are formed. When a material tape 2 is heated to its softening temperature, the tape 2 covers the side faces of the projected molds 6 in close contact states other than gaps between the projected molds 6, 6. The tape 2 is rotated with the rotation of the rotating drum 5 and vacuum-sucked through the slits 10, whereby the tape 2 between the projected molds 6, 6 is pulled. As a result, the tape 2 adheres to the full area of the projected molds 6. Furthermore, when the tape is further rotated and air is blown to the tape 2 by a cooling device, the shrinkage of the tape 2 is blocked by the projected molds 6, and the deformation of the tape 2 is prevented. In this manner, pockets 13 are formed in the tape 2.
