Abstract: Core data required to manufacture rolls in a film processing and cutting machine are obtained, and core data of cores supplied by a core supply apparatus are also obtained. These core data are compared with each other, and cores having the conforming core data are selected and supplied to the film processing and cutting machine. When supplied with the cores, the film processing and cutting machine winds films cut to a given length and width around respective cores, and then supplies obtained products to a main feed unit according to the sequence of address information established on a film roll.

Abstract: A web processing apparatus has a cutting mechanism for cutting elongate webs of different widths from a raw web, a core rotating mechanism for selectively holding cores having different diameters and different axial lengths and rotating a selected one of the cores in opposite directions, a winding mechanism for supporting one of the elongate webs on an outer circumferential surface of the core to wind the elongate web in different winding directions when the core is rotated, and a cutting mechanism for cutting an end of the elongate web to produce a roll after the elongate web is wound around the core.

Abstract: A method of and apparatus for checking a wrapping state of a wrapped roll having end face covers by detecting the force required to press-fit a bushing into a cylindrical core tube and comparing the detected force with a threshold value which is based on the correlation between the force required to press-fit the bushing into the cylindrical core tube and the state of tucking of the end face covers.

Abstract: A pillow type packaging apparatus has a suction belt for conveying flexible continuous sheet material. A guide unit guides the continuous sheet material being conveyed, and forms the continuous sheet material into a quadrangular tube in which a pair of its longitudinal edges are confronted with each other. A center sealer thermally seals up the longitudinal edges. An inserter inserts an article into the tube through the guide unit. The tube is formed into a packaging bag by cutting and sealing. In the guide unit, an inner guide frame is inside an outer guide frame. The outer guide frame includes first to fourth corner portions, which are disposed in a quadrangular shape, have inside edges in contact with the continuous sheet material, and shape the continuous sheet material into the tube. The first to fourth corner portions are movable in directions of width and height of the continuous sheet material. The tube is changeable in a size.

Abstract: A wrapping state of a wrapped roll of a continuous sheet material which is rolled and wrapped with a sheet-like wrapping material is checked by taking an image of the wrapped roll placed in a predetermined position, and processing information on the image of the wrapped roll with respect to the density of the image, thereby detecting data on wrapping state of the wrapped roll, and determining whether the wrapping state of the wrapped roll is satisfactory on the basis of the detected data.

Abstract: A turret punch press and a die set exchange device for the press are disclosed. The punch press includes a turret carrying die sets in die set attaching areas, and a die set exchanging device having a plurality of housings on a carriage, which moves horizontally between the turret and a die storage section to take out and charge die sets with the turret and the die set storage section to exchange the die sets for the next use.

Abstract: A turret punch press includes rotatable upper and lower turrets, a striker which is vertically movable for striking a punch, a plate positioning device for moving and positioning, in the X and Y directions, a plate workpiece supported on a work table, and a tool changing device, wherein a punch holder magazine and a die holder magazine supporting respectively a punch and a die to be installed on the upper turret and the lower turret to replace the punch and die in use, are provided adjacent to the upper and lower turrets. The punch changing position on the upper turret is below the punch holder magazine, and the die changing position on the lower turret is above the die holder magazine. The tool changing device is positioned on a vertical line between the punch and die changing positions so that the punches and dies can be changed by a direct linear operation.

Abstract: A packaging apparatus for packaging rolled articles. The apparatus forms a pair of packaging materials for wrapping side portions of the rolled article. Edges of the pair of packaging materials are adhered to additional packaging material which wraps a circumferential portion of the rolled article. A splicer splices a trailing end of the second packaging material to a leading end of the rolled article and a winder winds the leading end of the rolled article and the second packaging material around the periphery of the rolled article. A gusseting device gussets the pair of packaging materials along the sides of the rolled article.

Abstract: Packages of a rolled photosensitive material comprise a core and a photosensitive material wound around the core, and one package further comprises a light-shielding leader connected with an end of the photosensitive material to shield the circumferential surface of the photosensitive material from light and a pair of light-shielding covers adhered to both sides of the leader in a peelable state to shield the side surfaces of the photosensitive material.

Abstract: In a method and apparatus for packaging a rolled web, a feed roller is located near each of opposed end faces of the rolled web to be packaged. The axis of rotation of a feed roller is inclined with respect to the radial direction of the roll, which radial direction intersects perpendicularly to the direction along which a wrapping material having side edge parts folded in L-shapes is fed, such that the outer periphery of the axis of rotation, which outer periphery is taken in the radial direction of the roll, is more forward with respect to the direction, along which the wrapping material is fed, than the inner periphery of the axis of rotation. A folding member is located on the side more forward than the feed roller with respect to the direction, along which the wrapping material is fed. The folding member is supported such that the space between the folding member and the opposed end faces of the roll varies periodically.

Abstract: A turret punch press includes an upper and lower turrets for respectively supporting a plurality of punches and dies; the punches are arranged two-dimensionally in a punch mounting regions on the upper turret and the dies are arranged two-dimensionally in a die mounting region on the lower turret. The turret punch press further includes a ram and a striker for striking the punches. The striker is provided on a bottom of the ram so as to be movable in two horizontal directions above the punches indexed in a processing region. In the turret punch press, when the turret is indexed in the processing region, many punches and dies are simultaneously indexed in the processing region. Thus, by moving the striker in two horizontal directions above the punches indexed in the processing region, many successive punch operations can be quickly performed without intermediate rotation of the turrets.
