1. A rotatable core loading arm for loading a core in a paper winding machine having a roll and a roll stand, said core loading arm comprising:
- a primary arm including means for holding a core, the primary arm being pivotally coupled to the roll stand of the paper winding machine;
a secondary arm having a pivotal connection to the roll stand of the paper winding machine and a pivotal connection to means for moving the second arm; and
an intermediate link means secured to the secondary arm for creating a mechanical advantage causing the primary arm to rotate through an arc greater than the arm moved through by the secondary arm as the secondary arm is moved by the means for moving.
