HIGH PRECISION SINGLE FOCUS COLLIMATOR AND METHOD FOR MANUFACTURING HIGH PRECISION SINGLE FOCUS COLLIMATOR

摘要

PURPOSE:To even the contact of respective cutters, in a slitter by which a material to be cut is slit into a plurality of strips, by measuring the force required for the movement of the respective cutters on one shaft when the respective cutters are pushed on the respective cutters on the other shaft, and by judging the state of contact between cutters through the measured force. CONSTITUTION:When the cutters 7 of a first shaft 2 in a slitter and the cutters 10 of a second shaft 3 are combined by bringing them into contact with each other, first, a screw member 5 is tightened via a bearing 4 to move the first shaft 2 in the direction of A, so that the cutters 7 fitted on the first shaft 2 are brought close to the cutters 10 fitted on the second shaft 3. At that time, the pressure when the outer circumferential parts of the cutters 7 are pressed and brought into contact with the outer circumferential parts of the cutters 10 is estimated by measuring the tightening force of the screw member 5. When the tightening force of the screw member 5 reaches a precalculated value, it is judged that the cutters 7 are brought into contact with the cutters 10 with a proper force, and the tightening of the screw member 5 is stopped.
