    • A method and apparatus for edge sharpening a strip that provides a doctor blade or a squeegee blade (e.g. for use in screen printing), wherein a rotary cutting blade cuts through the strip between the opposite major faces of the strip, and at fixed angles to said major faces, while the strip is move longitudinally relative to the rotary cutting blade. The apparatus, which constitutes a strip blade edge sharpening machine, comprises a rotary cutting blade, a support structure to support the strip in upright attitude upon a minor face of the strip, and a mechanism to effect relative movement between the rotary cutting blade and the strip in a direction longitudinally of the strip such that the rotary cutting blade cuts through the strip between the opposite major faces of the strip, and at fixed angles to said major faces, at a location spaced by a predetermined constant distance from the strip's supported minor face.
    • 一种用于边缘磨削提供刮刀或刮刀(例如用于丝网印刷)的条带的方法和装置,其中旋转切割刀片在条带的相对主要面之间穿过条带并以固定角度 所述主面,同时条带相对于旋转切割刀片纵向移动。 构成条形刃刃磨边机的装置包括旋转切割刀片,支撑结构,用于将条状物以直立状态支撑在条带的小面上,以及一种机构,用于实现旋转切割刀片和 在条带的纵向方向上带状,使得旋转切割刀片在条带的相对的主要面之间切割条,并且以与固定的角度相对于所述主要面在与带的支撑的次要部分间隔预定的恒定距离的位置处 面对。
