摘要

PROBLEM TO BE SOLVED: To realize a string shift apparatus which can support a bundling machine having a rotary tying arm and is not limited by a size of a fixed table. SOLUTION: The string shift apparatus comprises a main arm 11 which is pivoted at a tail end by a pivot pin 17 and suspended by cylinders 13, 14 at a middle position to be lifted/lowered/rotated, an L-shaped auxiliary arm 12 rotatably mounted in a direction of opening from a position where it overlaps the main arm 11, an upper stopper 15 and a lower stopper 16 in contact with the auxiliary arm 12 above and below the main arm 11 to cause it to open, and a spring 18 for energizing the arm 12.
