IPC: B65B19/22
Filed: 1998-05-20
Abstract: PROBLEM TO BE SOLVED: To make reliable the cutting operation of a blank from a material web and replacement of the blank by providing a negative pressure source wherein suction force is small when cycle speed or rotation speed of a transfer roll is relatively low and the suction force is large when the cycle speed or the rotation speed is relatively high.

Abstract: PURPOSE:To improve the electric charateristics of a resin-molded coil by forming the length of an interlayer insulator projection projected from the lateral end of a coil conductor stack equal or less to the thickness of the coil conductor, thereby preventing the short circuit of the conductors. CONSTITUTION:A coil conductor 2 is wound through an interlayer insulator 10 made of aromatic polyamide, accociated mica sheet or the like having excellent withstand voltage charateristic and relatively preferable adherence to a molding resin on a coil frame and a coil body 20 is thus obtained.

Even if an exfoliation occurs in the vicinity of the end of the insulator 10, the coil conductors make no contact through the gap of vacuum state causing the short of the conductors. Accordingly, the electric characteristics of the coil can be improved thereby.
