To retain the virginity of cylindrical articles packed in a cylindrical article package, the present invention provides a package of a novel structure and a fabrication method for the same. More specifically, the present specification discloses a package wherein a film has a slit at least either one of an upper end face and a lower end face of the package in a portion thereof corresponding to a boundary between the adjacent cylindrical articles, and more specifically, a package wherein the film has a slit along the boundary between the adjacent cylindrical articles, and is curved in such a manner as to conform to the outer circumferential surfaces of the cylindrical articles located adjacent to the boundary.

Powder mixture is supplied into a die under a state that a center pin is located lower than the top surface of the die, after which the center pin is lifted up to a given molding position where an annular molding space is defined between the center pin and the die. The powder mixture is then compressed from upper and lower sides with an upper plunger and a lower plunger to form a pellet. The center pin and the lower plunger are simultaneously lifted up to remove the pellet out of the die.

An apparatus whereby cylindrical cans formed of a ferromagnetic material and transported at high speed along a carrying conveyor in such a contiguous way as having no gaps between adjoining cylindrical cans are separated so as to provide a spacing therebetween to eliminate interference between the adjoining cylindrical cans, thereby supplying a plurality of cylindrical cans with reliability to a main index wheel of an automatic machine for producing cylindrical cans. The apparatus includes a carrying conveyor, star index wheel, supply index wheel and main index wheel. The supply index wheel has permanent magnets, each holding an individual cylindrical can by suction. The transport speed of a plurality of cylindrical cans transported along a conveyor at high speed is reduced for a moment by the star index wheel. Then, each respective cylindrical can is held by suction caused by magnetic force from permanent magnets disposed around the outer edge of the disc-shaped supply index wheel and spaced uniformly to provide a spacing between adjoining cylindrical cans. While maintaining the foregoing spacing, the cylindrical cans are supplied to the main index wheel of the automatic machine for producing cylindrical cans.

A method of wrapping labels about batteries comprising the steps of peeling off individual labels provisionally glued on a band-shaped base paper, holding the individual labels on the surface of a continuously rotating label drum using suction forces applied trough holes or passages on the surface of the label suction drum, and wrapping the labels on the label suction drum on the outer circumference of rotating batteries continuously supplied by a battery conveying table. The apparatus of the invention comprises a battery conveying table for rotatably conveying batteries to a predetermined position for receiving the label, a label drum for holding the labels by suction forces and conveying the labels to the predetermined position, and a battery rotation belt for rotating the batteries while pressing the label to the outer circumference of the battery after the label is positioned by the suction drum, and wrapping the label to the outer circumference of the battery by rotating the battery.

The invention is intended to realize a battery convey jig capable of efficiently conveying and sorting in conveying step, in a manufacturing process of a variety of batteries. The jig is cylindrical, having a hole for accommodating a battery in the center, and an iron ring of a great specific gravity is buried as a weight in the lower part of the jig. Hence, stable supporting and conveying may be realized without increasing the bottom size of the jig.

A star index wheel with a plurality of semi-circular notches furnishes round or cylindrical articles to a supply index wheel of the automatic machine at an rate coinciding with the spacing of the semi-circular notches in the supply index wheel. The star index wheel is disposed on the side of a carrying conveyor on which the round or cylindrical articles are transported without any gaps between them. The star index wheel rotates at a speed whereby the semi-circular notches move at a speed slightly less than that of the linear speed of the carrying conveyor, so that the movement of the articles on the carrying conveyor is constrained by the protrusions provided between the semi-circular notches in the star index wheel. The rotational speed of the star index wheel also separates the articles to synchronize the rate at which they are supplied to the supply index wheel with the rotational speed of the supply index wheel.

A method and apparatus for putting small, slender, cylindrical cells in a box in an aligned row. By using the force of a magnet, multiple cells are suspended from the lower side of a conveyor belt, and are aligned and held in this position. By releasing the magnetic force, the cells drop, so that large numbers of cells, in a suspended and aligned state, can be simultaneously put into a cell container waiting below.
