The circular frequency of wire which was fixd at one end on a rotating stripping drum at uniform angular velocity was calculated by changing the fixing angle of wire and the rotating speed of stripping drum. The motion of wire deflected during the process of stripping cane leaves was analyzed in the racing of stripping drum between the position where wire took off sugarcane and the position where wire again collided with sugarcane, and the state of wire at the collision of wire top with sugarcane was investigated theoretically.<br>In order to estimate the dynamic force acting at the top of wire during the process of stripping cane leaves, the octagonal ring with plate for force transducer was put on the place where was at equal distance from upper and lower stripping drums of wire type sugarcane stripping machine, when the stripping drum was rotated at uniform angular velocity, the normal and horizontal forces acting at the top of wire rubbing the plate on octagonal ring was measured, and the direction and magnitude of acting force was obtained.<br>In order to confirm the theory of the motion of wire, the photographs of the state of wire in motion was taken with stroboscope.<br>The esults obtained was as follows.<br>(1) As the fixing angle of wire and the _rotating speed of stripping drum increased the circular frepuency of wire increased.<br>(2) The circular frequency of wire and the rotating speed of stripping drum significantly influenced the state of wire deflection at the collision of wire top with sugarcane.<br>(3) The force acting at the top of wire was influenced considerably by the state of wire deflection at the collision of wire top with sugarcane.<br>(4) When the rotating speed of stripping drum was lower, the acting force of wire was maximum at the place where the wire top took off sugarcane, and was large in the direction of the axle of wire, as the fixing angle of wire incleased the force of direction of the axle of wire decleased.<br>(5) When the rotating speed of stripping drum was higher, the acting force of wire was maximum at the collision of wire top with sugarcane, and was large in the direction perpendicular to the axle of wire.
