Abstract: Sheet-metal blanks for rotors or stators of electrical machines are cut from rolled sheet-metal strips with a magnetic preferential direction and layered to form a laminated rotor core or laminated stator core. To compensate largely for a magnetic anisotropy of the laminated rotor core or laminated stator core, the sheet-metal blanks, when they are not centrosymmetrical, are cut out together congruently in a single cutting operation, from rolled sheet-metal strips stacked one above the other and rotated relative to one another by an angle.

Abstract: An inserter input system including a web feeder providing a web of printed material to be split by a web slitting knife along the web's direction of travel. The split web is then cut transverse to the direction of travel by a web cutter, resulting in side-by-side individual sheets. Downstream of the rotary cutter, a right angle turn mechanism receives each of the side-by-side sheets and reorients them by ninety degrees. Further the right angle turn reorients the sheets into a serial shingled arrangement. The right angle turn transport operates at a velocity that is a function of the product of the web cutting rate and the width of the documents. A high speed separation nip pulls individual shingled sheets out from the shingled arrangement. The speed of the separation nip is such that a predetermined gap between the previously shingled sheets is formed. The separation nip speed is further controlled as a function of the product of the cutting rate and the sum of the document length plus the predetermined gap.

Abstract: A slicing and conveying system forms a three or more flavor-combined draft. A first slicing machine slices a succession of first and third slices in first and third shingled drafts. A second slicing machine slices a succession of second slices in second shingled drafts. A pass-through conveyor transfers the first draft to an output conveyor of the second slicing machine, wherein the second draft is added to the first draft to form a first combined draft. An overlap conveyor receives the first combined draft and merges the first combined draft with the third draft on the overlap conveyor to form an elongated combined draft. Optical sensors determine lengths of the first draft, the second draft, the third draft, and/or the elongated combined draft.

Abstract: A method for optimizing the cutting of sheets of material that are stacked on a bench in a cutting machine. Before cutting the sheets, a beam descends to hold the sheets fast while guillotine blade descends and cuts the sheets. After the sheets have been cut, the blade and beam are lifted, with the lower edge of the beam following the sharp edge of the blade. A definite distance between the blade and the top of the stack is determined while the blade rises after cutting the sheets. The rise of the blade is terminated at the upper end of that distance, which is determined by a pick-up mounted stationary on the holdfast beam. This pick-up detects the position of the rising blade in relation to the holdfast beam.
