摘要： A method (100) of producing toothed blades from a strip material (200, 250) is disclosed. The method (100) comprises: cutting the strip material using combined laser cutting (102a) and mechanical machining (104a) or using waterjet cutting (102b) to form a plurality of teeth in an edge of the strip material (200, 250), wherein the cutting is controlled to cut each of the teeth using a flexible programmable geometry. A toothed blade production line (300, 400) arranged to produce toothed blades from a strip material using the method is also disclosed.

摘要： A metallic card wire has an elongated rib portion and teeth. The teeth have a front segment, a top segment and a back segment. The front segment has the connection of the tooth from the elongated rib portion and the front segment including a tip which is actively taking fibers in carding. The top segment has at least one hunch after the tip in the direction of the back segment. If more than one hunch is present the first hunch is the hunch positioned closest to the tip; if only one hunch is present this hunch is the first hunch. The back segment forms the connection of the top segment towards the elongated rib portion and the front segment of the next tooth.

摘要： A hedge trimming tool having a fixed elongated blade mounted to the power head of the tool and a cutting blade mounted over the fixed blade and reciprocating relative to the fixed blade in the direction of the lengthwise axis. A leading side of the fixed blade has projecting fingers or teeth and the overlying portion of the cutting blade has projecting teeth that reciprocate across the openings between the fingers. The reciprocating teeth have sides configured in a complex curve forming an hour glass planar profile and an inverted U-shaped cross section. The U-shaped cross section is provideed by curving the sides of the teeth downwardly whereby the teeth sides are angularly projected through the plane defined by the bottom surface of the blade. The cutting edges along the sides are formed by grinding faces through the portions of the teeth projected below the bottom surface of the blade. The faces are formed in a single pass of the grinding implement with the faces parallel to the bottom surface of the blade.
