摘要： A flying shear is disclosed having upper and lower blade assemblies wherein upper and lower blade holders can be slid endwise out of the machine when replacing cutting blades and are rigidly clamped in position by adjustable tapered wedges acting against shoulders on the blade holder. The lower blade holder is mounted on a trapezoidal mounting member which has a small taper on both sides and is clamped between two oppositely tapered wedges in such a way that the gap between the cutting blades can be adjusted very easily while maintaining substantially perfect alignment of the blades by sliding the wedges lengthwise. Adjusting screws are provided to simplify this adjustment. Dovetail joints are provided between the side edges of the upper blade holder and its cooperating wedge and upper mounting member to prevent the upper blade holder from dropping out of its mounting member.
