Abstract: A rotary printing press has a folding station where the printed web is perforated both transversely and longitudinally in order to expedite subsequent folding thereof into signatures. In order to incorporate a longitudinal perforator into the folding station without adding to its size, a longitudinally perforating blade similar to a circular saw is mounted to a blade carrier shaft which is rotatably supported opposite a feed roller by which the web is frictionally fed into and through the folding station. An annular, longitudinally grooved anvil is formed circumferentially on the feed roller for engaging the longitudinally perforating blade via the web being thereby perforated. The longitudinally perforating blade is movable with the blade carrier shaft into and out of perforating engagement with the anvil on the feed roller.

Abstract: The invention relates to a process for producing bundles consisting of laminated sheet metal for magnet cores, wherein laminations are punched free along two longitudinal edges of a sheet metal strip, wherein at least two sheet metal laminations of a magnet core are of a different width extending from one longitudinal edge to the other, and wherein several laminations, which rest against each other, are connected with each other to form the bundle. To simplify the tool control it is provided in accordance with the invention that the two longitudinal edges of a lamination are punched in edge cutting stations, which are separate from each other and are arranged offset in the feed direction of the sheet metal strip, that the edge cutting stations for cutting the longitudinal edges have a cutting die and an associated bottom die, and that the cutting die, together with the bottom die, is displaced for creating different laminate widths.

When a wire goes to a rightward direction by a rotation of a moving motor, the wire is inclined in such a manner as to be moved toward a right and outer periphery from an inner portion of a work, and a cutting start point of the work becomes a point within the work. Further, when a wire goes to a leftward direction by a rotation of the moving motor, the wire is inclined in such a manner as to be moved toward a left and outer periphery from an inner portion of a work, and a cutting start point of the work becomes a point within the work. Then, the work is cut from the cutting start point by a sufficient slurry containing float abrasive grains supplied to a portion on the wire.

Abstract: A food slicer comprises a storage reservoir, a cutting blade housing with cutting blade therein and a top lid. The reservoir, housing and top lid are releasably connected to each other by complementary hinges. A cutting blade comprises a frame having a plurality of cutting wires spanning the frame is releasably engageable within the cutting blade housing. Upon placement of a food product on the cutting blade, downward pressure of the open lid urges the food product passed the cutting blade wires, the resulting food product slices falling in the storage reservoir therebelow. The storage reservoir is releasably engageable from the cutting blade housing to enable the reservoir to be used as a separate serving and/or baking dish. A releasable engagement of the cutting blade with the cutting blade housing allows for a plurality of variously configured cutting blades to be utilized.

Abstract: A process for producing a steel punching sheet that has the same ideal dimension over the entire length of the punching edge has the following steps: producing webs carrying punching edges on a steel starting sheet; processing the punching edges, wherein the distance between the punching edges and the back of the sheet is adjusted to a positive tolerance with respect to an ideal dimension; and grinding the back of the sheet to remove material in excess of the ideal dimension to within a tolerance of not more than 0.02 mm, more particularly a tolerance of not more than 0.005 mm. Advantageously, the process includes the following additional steps: adjusting the distance between the punching edges and the back of the sheet to a negative tolerance, with respect to an ideal dimension, and applying material to the back of the sheet to make-up for the negative tolerance up to a positive tolerance of not more than 0.02 mm, more particularly, a tolerance of not more than 0.
