摘要： A cutting blade for vegetation is provided for example for use in a straw chopper or rotary mower. The blade includes a first base material and a plurality of hard surface beads of at least two different materials formed on at least one surface of the base material extending up to a cutting edge of the base material wherein the plurality of hard surface beads lie alternately side by side with touching side edges and one contains at least one different material of a different hardness relative to the other so that differential wear rates are created, and a wear profile is controlled. The softer material is burnt away at the edge by the cladding laser to form pockets so that the blade is serrated by the pockets when supplied with additional wear increasing the pockets to maintain the serrations.

摘要： An automatic bending apparatus for bending a band-shaped work at a plurality of positions in sequence with intermittent feed of the work in a longitudinal direction thereof. The bending apparatus includes a swingable work holder for holding the work and a fixed bending jig for bending the work in cooperation with the work holder. The work projecting from an outlet of a passage formed in the holder is pressed against the jig by swinging the holder to approach it toward the jig. After bending the work, the holder is returned to a neutral position, and the work is fed to be projected from the outlet, then repeating the above operation. In marking the work with a cutter, a cutting sound detecting device such as a microphone is provided to detect whether the cutter has come into contact with the edge of the work. Further, a depth of cutting from the edge of the work is controlled to be constant on the basis of a timing of detection of the cutting sound.
摘要翻译：一种自动弯曲装置，用于在多个位置上顺序地弯曲带状工件，同时沿着其纵向方向间歇地进给工件。弯曲装置包括用于保持工件的可摆动工件保持器和用于与工件保持器协作地弯曲工件的固定弯曲夹具。从保持器中形成的通道的出口突出的工件通过摆动保持器而被压靠在夹具上，以将其靠近夹具。在工件弯曲之后，保持器返回到中立位置，并且将工件供给以从出口突出，然后重复上述操作。在用切割器标记工作时，提供诸如麦克风的切割声音检测装置以检测切割器是否已经接触到工件的边缘。此外，根据切割声音的检测定时，将从工件边缘切割的深度控制为恒定。

摘要： The method of manufacturing the knife blade (1), comprises the following steps: by stamping the two faces (1a, 1b) of a blade blank (1), a series of protuberances (2, 3) are formed, extending transversely to the length of the blade and, during the same stamping operation, a chamfer is formed on one of the longitudinal edges of the blade, after which, said edge (5) of the blade opposite the chamfer is sharpened. Use especially in order to avoid the blade sticking when cutting food.
