Abstract:
A magnetic recording medium including a magnetic layer 93 containing ferromagnetic powder and a binder, a support 91, and a backcoat layer 94, provided in this order, and being obtained by slitting to width a magnetic material of broad width and continuous length. The magnetic recording medium has no ridge protruding above the surface plane of the magnetic layer along the slit edge thereof. The magnetic recording medium achieves large recording capacity, is free from the tape pack problems such as appearance of a radial pattern and the output reduction problem, produces no fine scrapings in high speed running, which would cause head clogging and dropouts, thereby exhibiting good running durability and electromagnetic characteristics, and is particularly useful for computer data storage applications.
Abstract:
The invention relates to a separation device (400) for separating portions (04) of a material web (02), the separation device (400) having at least one front clamping device (406), with at least one front clamping point (401), and at least one rear clamping device (404), with at least one rear clamping point (402), and at least one first stretching element (403). The separation device (400) can be switched between at least one traversing mode and at least one separation mode by the movement of at least the at least one first stretching element (403) between at least one first traversing position and at least one first separation position. A transport line is the shortest connection between the at least one front clamping point (401) and the at least one rear clamping point (402), said connection lying completely on a vertical reference plane and traversing or running at a tangent to any component of the separation device (400) on the respective same side as a transport path provided for the material web (02) and/or the portions (04), wherein the transport line in the at least one separation mode is 2 mm longer than in the at least one traversing mode and has the smallest radius of curvature in the at least one separation mode of at least 0.05 mm. A first reference plane and a second reference plane are mutually spaced apart in an axial direction (A) and a first transport line lying on the first reference plane and a second transport line lying on the second reference plane have different lengths when the first stretching element (403) is located in the at least one first separation position.

A slotter head, a slotter apparatus, and a box making machine form a joining piece with a high degree of accuracy by each being provided with: a cutter rest (101); a movable block (103) mounted in an outer peripheral portion of the cutter rest (101); a first cutting blade (104) that is fixed to the movable block (103) along a shaft direction and along a direction inclined in a circumferential direction by a predetermined angle (¸); a first support shaft (106) that supports, on the cutter rest (101), the movable block (103) rotatably around a first shaft center (O1) along the shaft direction; and a second support shaft (107) that supports, on the cutter rest (101), the movable block (103) rotatably around a second shaft center (02) along the circumferential direction.
Abstract:
Die Erfindung betrifft eine Vorrichtung zum Durchschneiden, Einschneiden, Durchperforieren oder Einperforieren von Blattmaterial, wie Papieren, Metallfolien oder Kunststofffolien, insbesondere von auf einem nicht zu beeinträchtigenden Trägermaterial befindlichen Etikettenmaterial, mittels einer lösbar koaxial zwischen einer Widerlagerscheibe (2) und einer Andruckscheibe (4) einzuspannenden Schneidscheibe (6), deren Außendurchmesser (D6) etwas größer ist als der Außendurchmesser der Widerlagerscheibe (D2) und der Andruckscheibe (D4), dadurch gekennzeichnet, daß die Schneidscheibe (6) eine so geringe Dicke hat, daß mit ihrer Umfangsfläche (8) die Schneidarbeit bzw. Perforierarbeit auszuführen ist.

Abstract:
The present inventions provide a method and an apparatus for cutting flattened food dough into long-shaped food dough, without adding stress to the food dough. The method for cutting flattened food dough 3 into a long and continuous shape, comprising: (a) a process for cutting the flattened food dough 3 by moving a cutter 7 relative to the food dough 3 from one lateral end to the other lateral end of the food dough 3, and a process for discontinuing the cutting process by lifting up the cutter 7 from the food dough 3 so that an uncut part is left near the other lateral end; (b) a process for cutting the flattened food dough 3 from the other lateral end to the one lateral end of the food dough 3 after moving the cutter 7 relative to the food dough 3 along the direction perpendicular to the direction to cut the food dough 3, and a process for discontinuing the cutting process by lifting up the cutter 7 from the food dough 3 so that an uncut part is left near the one lateral end; (c) a process for moving the cutter 7 relative to the food dough 3 along the direction perpendicular to the direction to cut the food dough 3; and (d) processes for repeating the processes (a) to (c).
