Abstract: A slitter mechanism for slitting elongated webs of material into narrower webs by operative blades on parallel shafts. Inoperative blades are provided in an idle zone on said shafts. The blades in the idle zone are movable out of contact with each other without interfering with the mating relationship of the operative blades.

Abstract: An automatic cutter positioning device in a gang slitter consisting of a frame assembly having an upper frame including rails, a lower frame including rails, and side frames. Cutter heads are slidably mounted to the upper and lower rails. Cutter shaft journalling cases are vertically slidably mounted on each cutter head. Spline shafts journalled by the side frames provide driving force to the cutter shafts through gears and belts. The cutter heads are moved so that the forward head moves faster then the rearward head.

Abstract: A sheet perforator head having a perforating wheel rotationally supported on a solenoid-operated, toggle-actuated leverage arm and capable of perforating according to program.

Abstract: In a slitting apparatus for a web of material such as paper, comprising a circular knife which, in its operation position, co-operates with one of a plurality of counter-blades defined at the periphery of a grooved roller, the rotary axis of the knife in the operative position of the latter is inclined at an acute angle to the roller axis.

Abstract: A tool positioning apparatus which is adapted to position by numerical control a plurality of pairs of tools attached to a pair of parallel shafts so that longitudinal slits, scores or the like may be produced along a web of board such as corrugated board conveyed through between said pair of shafts is provided with a tool positioning apparatus, said apparatus comprising tool feed control devices which are provided correspondingly to the number of said pairs of tools and are movable respectively on a guide member disposed parallel to said shafts by driving motors which are numerically controlled by a positioning controller and which have shifters insertably engageable with pairs of tool holders corresponding thereto respectively on which said pairs of tools are fixed; and a moving device which enables said shifters to engage with and disengage from simultaneously said pairs of tool holders corresponding thereto respectively.

Abstract: A simple direct acting mechanism moves a circular rotatable disc cutter or two such cutters first to rollably engage a hard surface and then to traverse the surface to part the stock between a side-by-side pair of cords or wires. The cutter or cutters are blunt edged, as well as unheated and so avoid baring the cords or wires while parting the stock without the undesired effect of sharp or hot knives. The cutter or cutters are shiftable along the axis or axes to accommodate deviation of the cords with respect to the travel of the cutter. The foregoing abstract is not to be taken as limiting the invention of this application, and in order to understand the full nature and extent of the technical disclosure of this application, reference must be made to the accompanying drawing and the following detailed description.

Abstract: A web is cut in a printer by a carriage driven stepped roll being urged against a stationary cutting edge so that a tear point travels ahead of the engagement of the roll with the edge and the paper. The roll can be retracted and latched into a non-cutting position.

Abstract: A device for longitudinal cutting of a thermo-softening material into strips, such as strips of a separating material for battery electrodes comprising a roll holder, two pulling rollers having their rotation drive installed parallel and near to said roll holder, and said rollers moving the band in the course of cutting and delivering the cut strips onto the receiving shafts of a wind-up mechanism. A common shaft parallel to the pulling rollers is located under a cutting mechanism and carries electric cutters secured on arms; the hubs of said arms are fastened with the aid of intermediate sleeves on said common shaft. Both the hub and the intermediate sleeve are provided with segment teeth which interact with each other during the turning of the common shaft thereby lifting automatically the electric cutters.

Abstract: Sheet slitting and punching apparatus for cutting a large elongate sheet of paperboard or similar material into a plurality of rectangular cards of uniform size and punching holes in each of the individual cards. A large sheet is fed along a conveying means having two tandemly arranged feed sections separated from each other by a transverse and a longitudinal slitting station. Both feed sections of the conveyor are driven from a common drive means, however, the upstream or infeed section is driven at a conveying speed substantially slower than that of the downstream or outfeed section. Transversely spaced slitters form longitudinally extending slits in the sheet as it is fed along the conveying means. When the feeding end of the sheet reaches a predetermined location near the upstream end of the outfeed conveyor, it engages a sensing element which immediately stops the conveyor drive.

Abstract: An original to be copied is supported in a predetermined position. A sheet of copying paper is transported through the copying or duplicating machine in a predetermined travel direction along a predetermined travel path and into a delivery station. The original is illuminated and an image thereof is formed on the sheet of copying paper as the sheet travels along the path. A cutting arrangement is arranged upstream of the delivery station and is operative when activated for cutting the sheet along a line extending parallel to the travel direction of the sheet as the sheet leaves the copying station and travels to the delivery station. The cutting arrangement is activatable by the user of the machine.

Abstract: Apparatus for cutting sheet material suitable for use with a card-dispensing business machine is disclosed. The apparatus includes cooperative roller mechanism having side by side cylindrical portions of selected different diameters, which define cutting edges to slit sheet material fed therethrough. The cutting edges are preferably formed by undercutting the ends of the cylindrical roller portions defining the cutting edges, thereby to form sharp cutting surfaces.

Abstract: A device for the longitudinal cutting of webs comprises two hollow shafts, each bearing a blade, and supported on a respective spindle. One spindle is supported eccentrically in a frame so that its rotation sets the inter-axis spacing of the two shafts, whereby the blades may be engaged and disengaged in the radial sense. The same spindle is displaceable axially whereby the blades may be engaged and disengaged in the axial sense. Both operations are performed by means of one and the same handle. Means is also provided for displacing simultaneously both spindles in the axial directions in order to position the blades relative to the web.

Abstract: An electromechanical writing device comprising a writing head, a writing head carrier for carrying the writing head, a guide along which the writing head carrier is movable during a writing operation, a writing platen over which, in operation, a recording medium, e.g. paper, is moved during the writing operation, a shearing edge forming part of the writing platen and extending in a direction parallel to the direction of movement of the writing head, and a roller knife mounted for movement along the guide and cooperating with the shearing edge to permit the recording medium to be cut.
