Abstract: The present invention provides for a method and apparatus of horizontally stacking a stator core. A central rail structure 34 that runs down approximately the center axis of the stator frame 2, and attached to the central rail structure are adjustable supports 40 that hold the central rail structure within the stator frame. A dolly 36 is positioned on top of the central rail structure 34. The dolly 36 has multiple finger supports 38 disposed on its top and the finger supports match corresponding grooves in stator core laminations 10. Lamination are placed onto the dolly, gaps in the lamination engage the finger supports on the upper inner diameter of the lamination. This allows for the lamination to be horizontally moved into place within the stator frame.

Abstract: A trimmer (1) is disclosed from trimming excess margins (M) along one, two or three edges of a perfect bound book (B) is disclosed. The trimmer has a shearing blade (15) movable in a shearing plane (SP) between an open and a closed position. The book is gripped by a book holder (35) proximate the spine (S) of the book and the book holder is vertically positioned such the shear blade will shear the book in a predetermined position along this first edge of the book. The book holder is then moved transversely with respect to the blade and the book is rotated 180° and the book holder is vertically positioned so that a predetermined amount of the margin along this second edge is trimmed from the book upon closing of the shear blade. The book is then moved transversely to a third position and the book is rotated 90° and the book holder is vertically positioned so that a predetermined amount of the margin along this third edge is trimmed from the book upon closing of the shear blade.

Abstract: A press has a die unit, a feed mechanism and a table unit. The feed mechanism feeds a sheet of material to the die unit. The die unit has a punch and a die for punching first and second holes in the sheet. The punching axis of the punch is inclined at an acute angle with respect to the sheet. The table unit supports the die unit and rotates the die unit with respect to the sheet to direct the punching axis in different directions to form the first and second holes in different directions.

Abstract: A sheet feeding device of the present invention includes a cutter capable of being moved back and forth by hand between two reference positions outside of a sheet conveyance range. When the cutter is held in a halt at a position other than the reference positions, the sheet feeding device returns a sheet toward the upstream side by a preselected amount and then returns the cutter to one of the reference positions. Even when the cutter moved by hand for the replacement or the replenishment of a sheet is left in the sheet conveyance range, the cutter is prevented from again cutting the leading edge of the sheet when returning to the reference position. This protects the leading edge of the sheet from defective cutting.

Abstract: To achieve this and other objects, a first and second aspect of the present invention provides a first step of press forming first holes in a sheet while feeding the sheet one way through a press. A second step is provided wherein second holes in the sheet are formed while feeding the sheet in the opposite direction to that of the first step. A third step is provided which cuts the sheet to predetermined dimensions.

Abstract: A manufacturing method and a press apparatus improve the productivity of the manufacture of a press-formed object from a sheet blank, such as a nozzle hole plate of a fuel injector. The nozzle hole plate of a fuel injector has a plurality of holes differing, for example, in size and punch direction with respect to the sheet blank. In the case of the manufacture of a nozzle hole plate, a first amount of nozzle holes of equal punch angle and size are formed continuously by a die unit in a bandlike sheet blank workpiece while the workpiece is fed through the die unit one way in its length wise direction. Then, the feed direction is reversed, and the die unit is rotated and a further amount of nozzle holes are formed continuously by the same die unit. As a result, the number of die unit positioning operations involved in forming a quantity of nozzle hole plates is equal only to the number of different nozzle holes formed in each nozzle hole plate.

Abstract: A method used for rounding the corners of a pile of sheets. Air is injected between the sheets in the pile to create a lubricating fluid film between the sheets; at least one of the corners of the pile is placed in abutment against two reference surfaces formed facing at least one corner of the pile, and the four cutting devices corresponding to each corner are actuated.

Abstract: An inventive apparatus for feeding rolled paper comprises rolled paper, a feed roller for feeding the rolled paper, a cutting unit for cutting the rolled paper, a driving source for actuating the feed roller and the cutting unit, a first gear train interposed between the driving source and the feed roller and a second gear train interposed between the driving source and the cutting unit. A reverse feed gear for transmitting driving force for a cutter gear to a feed gear is interposed between the first gear train and the second gear train and connects the first gear train with the second gear train when a movable cutter moves from a cutting position to a non-cutting position. Thereby, the feed roller is rotatively driven in the direction opposite to the feed direction by the driving force from the cutter gear.

Abstract: In an apparatus for introducing a belt-shaped material to a cutting machine, stationary conveyors are laid vertically in such a manner as to form different angles with respect to the cutting machine and combined respectively, with lift conveyors which are also laid vertically to convey belt shaped materials to the cutting machine. The lift conveyors are moved vertically by lifting means unit a desired one of the lift conveyors comes to the belt-shaped material introducing position of the cutting machine.

Abstract: A letoff truck having wheels for rolling the truck to and from a bias cutter feeder is releasably connected to the feeder for movement of the truck with the feeder during angular adjustment of the feeder for a desired bias angle setting. The truck is also mounted for transverse movement relative to the feeder to compensate for deviations in the position of the edge of the goods conveyed from the letoff truck to the feeder. Adjustment of the feeder angle about a pivot axis to provide the desired bias angle setting is provided by a powered sprocket mounted on the feeder and positioned between idler sprockets. The sprockets are engageable with a chain member extending between the ends of a transverse track on which one end of the feeder is supported by rollers. When the desired feeder position is obtained the feeder may be positively locked in that position.

Abstract: A stamping or nibbling machine, comprises a workpiece support or means for engaging the workpiece at a spaced location from a punch which reciprocates upwardly and downwardly in respect to a die in order to effect the stamping or nibbling of the workpiece. The support is mounted on a transverse bar which is pivotable about a transverse guide and the guide is carried on a carriage which is pivotable about a longitudinal guide. The workpiece is fed by holding the bar and the carriage against pivotal movement and driving them in the respective longitudinal direction when the punch is lifted off the workpiece. The rate of this feed may be controlled in timed relationship to the movement of the punch so that the feed takes place when the punch is off the workpiece and in a speed of feed which is determined in accordance with the torque acting on the transverse bar and the carriage when they are released for pivotal movement and sensed by associated torque meters.

Abstract: Transformer core sheets are cut out by selectively intermittently advancing a metal strip and cutting off the ends at various angles by changing the cutting angle of a swivel-type cutting shear. Trapezoidal or parallelogram pieces are cut by cutting off the lengths of strip along shear lines alternately at 90.degree. to each other. Hexagonal pieces are formed by severing the strip with one oblique cut, spacing the stock and the cut-off piece lengthwise from each other, and then cutting off a tip on each piece by a single cut that bridges the gap between the pieces, at 90.degree. to the previous cut. For this purpose, the cut-off piece may be advanced or the stock retracted, or both, to space apart the stock and the cut-off piece. A further cutter, at right angles to strip travel, may be provided for cutting off tips of the workpieces previously obliquely cut, at right angles to the direction of strip movement.
