ABSTRACT:
The invention relates to an article transfer apparatus with clamper which rotationally transfers an article, held between a pair of clamp arms, as a rotatable body rotates. The clamp arms are driven for swinging motion in response to the rotation of clamp shafts, which are driven for rotation by a cam mechanism. An adjusting mechanism controls the angle through which the clamp shafts rotate until a given angle position of rotatable body is reached, thereby controlling the degree of swinging motion or opening between the pair of clamp arms so as to permit articles of different sizes to be grasped or released at a given position.
