1. A tool head for moving a tool, comprising:
a first shaft operatively connected to the tool;
a combination drive movable in a vertical direction and having an output in the form of a second shaft, said combination drive including a first rotary drive to rotate the second shaft, and a linear drive to move the second shaft in the vertical direction;
a pivot pin operatively connected to the second shaft so as to be rotatable and linearly movable by the combination drive; and
a second rotary drive operatively connected to the first shaft to rotate the first shaft, said second rotary drive being pivotably mounted to the pivot ping;
the tool head further comprising a drive to move the combination drive in the vertical direction and to thereby linearly move the tool at a first acceleration, said linear drive of the combination drive being constructed to linearly move the tool at a second acceleration which is greater than the first acceleration.
