摘要： A manufacturing method of a metal strip coil for blades includes performing, on a steel band after a finishing cold rolling, a slit process that divides the steel band into a plurality of metal strips via joint operation of circular upper and lower blade cutters, and winding the metal strip into a coil shape after the slit process. In the slit process, a clearance of the upper and lower cutters is set within 5-25% of a metal strip thickness; an overlap amount of the upper and lower cutters is set within 5-80% of the metal strip thickness; and a clearance variation during the slit process is 30% or lower of the clearance. After the slit process, the metal strip is wound into a coil shape so that sag formed on an edge of the metal strip is positioned toward an axis center of a reel winding up the metal strip.

摘要： Provided is a slitter device capable of quickly supplying metal bands to a cutter stand and cutting same into strips with high speed and accuracy. The metal band slitter device comprises an unwinder that unwinds a metal band wound into a coil, a cutter stand that cuts the unwound metal band into narrow width strips, and a winder that winds the cut metal band into coils. The metal band slitter device is configured to comprise a tension adjustment unit on the winder side between the unwinder and the cutter stand that provides a constant tension to the metal band and a tension separating unit on the cutter stand side that separates the constant tension on the input side and tension on the output side.

摘要： A multi-head film slitter slits wide film having a photosensitive emulsion layer oriented upwards to produce motion picture film. A lower rotary blade has a lower cutting edge. An upper rotary blade has an upper cutting edge, for shearing the wide film with the lower cutting edge. The upper and lower cutting edges are overlapped partially, and contact one another in a position downstream in a running direction of the wide film. A clearance is provided between the upper and lower cutting edges in a position upstream in the running direction. Also, a lower blade shaft rotates the lower blade. An upper blade shaft is disposed higher than the lower blade shaft, for rotating the upper blade. The clearance is provided by inclining the upper blade shaft on a plane on which the upper blade shaft lies and which is parallel with the wide film.

摘要： An apparatus for slitting sheet material to a desired width includes laterally spaced circular slitter knives each fixed to a hub mounted on a rotatable shaft, each said hub being an hydraulic hub adapted to be expanded to permit axial movement on the shaft by injecting hydraulic fluid into an annular groove in the inside diameter of the hub. The novel feature comprises spacer rollers between the slitter knives to support the sheet material, these spacer rollers being arranged in cooperating pairs with each spacer roller comprising an annular hub portion with a plurality of equally spaced projections extending in an axial direction from at least one annular face of said hub. The projections are adapted to slidably mate with like projections of a cooperating spacer roller and each spacer roller hub is adapted to be expanded to permit axial movement thereof on the shaft by injecting hydraulic fluid into an annular groove in the inside diameter of the spacer roller knife hub.

摘要： Apparatus for cutting labels from a ribbon on which the labels are printed. The ribbon is fed into the apparatus along a vertical plane, for instance. There are vertically spaced apart knives adjacent the ribbon for cutting the upper and lower contours of the labels from the ribbon. The knives are caused to pivot toward the ribbon and to rise and fall under the influence of a cam that is shaped correspondingly with the desired contours. After the upper and lower contours are formed the ribbon is caused to change direction around a roller while at the same time the trim margin is deflected in another direction and drawn away. The ribbon, with labels still connected endwise is fed over a vacuum cylinder which has cutters at its periphery for separating the labels from a waste portion between them. The labels are removed from the vacuum cylinder and led to a label applying machine, as an example.

摘要： The invention makes use of the controlled, differential application of heat to effect dimensional control in the slitting or stamping of metal workpieces. In a principal embodiment (FIG. 1), a metal strip (40) supplied from a reel (2) is slit into narrower strips by a slitting mechanism (12, 13) and the slit strips (41) are reeled up separately (at 23). A controllable heating apparatus (8, 9) is provided before the slitting mechanism (12, 13) and is arranged to effect heating of the strip (40) in a controlled manner which varies across the width of the strip (40) to compensate for variable tension in the strip across its width. Other applications of controlled, variable heating are also described.

摘要： A slitting machine of the type having a pair of spaced, parallel arbors and at least one pair of mating rotary knives, each arbor carrying one mate of each pair of rotary knives, each rotary knife being positioned in a desired axial relationship with its mate on the other arbor, this desired relationship being maintained by manual or automatic control of the relative positions of the arbors by rotatably mounting at least one end of at least one arbor in a slideable sleeve which may be cam driven in both axial directions. Axial backlash is reduced by maintaining the arbors in compression with a spring loaded tailstock.
