<p>Flying shear apparatus is disclosed suitable for cutting elongated strand material as it moves in a predetermined path. The apparatus includes two crankshafts having eccentric crank pins on which knife holding portions are rotatably mounted, each knife holding portion being rigidly connected to one end of a link member the other end of which is pivotally connected to a movable member that reciprocates in a fixed path, both link members being pivotally connected to the movable member about a common axis. Furthermore, the apparatus includes means to permit individual adjustment of the angular position of a crankshaft relative to the other, to permit adjustment of the cutting blade clearance. The slidable member also acts as a guide for the strand material being cut. The arrangement provides positive control and synchronization of the relationships of the cutting blades relative to each other at all times.</p> |
