摘要:
A die cutting apparatus for forming die cuts from paper and other materials includes a metal base plate defining at least one channel therein for receiving at least one blade. The blade has a desired shape to provide a cutting edge with a predetermined contour to substantially match the contour of the at least one channel. The blade is welded to the base plate to secure it relative thereto and extends above the base plate to provide an exposed edge for cutting paper and the like into the predetermined contour. A covering is provided over at least a portion of the back surface of the base plate.

A dust clearing band saw blade that includes a body having a blade thickness with a blank side and a cutting side. A plurality of spaced teeth having cutting edges are formed on the cutting side of the body, and a blade valley is defined between the adjacent teeth. A cut out is also positioned in front of the cutting edge of each tooth, whereby the cut out extends through the blade thickness and below the blade valley. A method for clearing sawdust from a band saw blade is also disclosed.
摘要:
A circular saw machine having a saw blade (1) that is movably held for back and forth motion during the sawing process. A forward and a rearward saw blade guide (4, 5) ensure the stability of the saw blade (1) while sawing. The saw blade guides (4, 5) respectively have contact surfaces (6), which abut on the respective side surfaces of the saw blade (1). In order to operate the circular saw machine with different saw blade diameters, the forward saw blade guide (5) is removable from, or pivotable away from, the saw blade (1), and the saw blade itself is interchangeable. The radial positioning of the contact surfaces (6) of the saw blade guides (4, 5) is variable. This can be accomplished by interchanging the whole saw blade guide (5), but also in particular by a mounting (12), pivotable with respect to the saw blade guide (4, 5) and to which the contact surface (6) is fixed.

In cutting devices (10), in particular microtomes or ultramicrotomes (24), it is necessary to preset the specimen onto the knife (14). To improve the accuracy and reproducibility of this presetting operation, which is intended to ensure the quickest and most accurate possible positioning of the knife (14) relative to the specimen, a pivotable observation device (10), in particular a stereomicroscope, is provided. The observation device (10) is coupled to a pivoting device (28) that comprises a positioning device (29). The positioning device (29) is embodied in such a way that a positioning of the observation device (10) at a defined angle is possible.
摘要:
A food slicer includes a frame with a food-receiving platform having an aperture therein. A reversible cutting blade has first and second cutting edges and is selectively removably mountable on the frame in first and second positions for respectively disposing the first and second cutting edges in the aperture for engagement with food being moved along the platform. Support legs are rotatably carried by the frame for movement between a stowed position disposed against the frame entirely between inner surfaces of side walls thereof and a use position extending from the frame and laterally outwardly of the inner surfaces of the side walls.

A steel rule cutting die is provided and includes a baseboard, and cutting knifes including an integral cross member having holes having a first diameter. The cutting knifes may be bent to form an enclosed cavity. Fasteners including a head and a shaft having second and third diameters, respectively, are provided, and are disposable within the hole in the cross member for connecting the cutting knife to the baseboard. Washers including a fourth outer diameter and a hole having a fifth diameter, are provided. The first diameter may be greater than the third diameter, the second diameter may be greater than the fifth diameter, and the fourth diameter may be greater than the first diameter, such that, when the washer is disposed under the fastener head, the washer prevents the head from entering the hole in the cross member, and facilitates translation of cavities parallel to the baseboard.

A trimming device having a trimming knife for trimming a brochure along a trimming plane at a front end of the brochure has one or more suction elements in the area of the brochure to be trimmed. The brochure has a cover and an inner book cased in the cover with flaps of the cover being flush with or protecting past the inner book. The suction element is configured to bulge a flap and retract a flap away from the trimming plane.
摘要:
A paper feeding device and method, wherein a tray including a paper loading unit, a paper feeding device, a paper cutting device is slid out of a main body of an image forming apparatus. When a new rolled transfer paper is loaded in the paper loading unit, the rolled transfer paper is conveyed so that a tip portion thereof is discharged from a rolled transfer paper outlet of the tray. The discharged tip portion of the rolled transfer paper is cut by the paper cutting device.
