Abstract
A scoring bridge includes a plurality of moveable mounted carriages. The carriages each have a rotor, and the bridge has a linear stator to move the carriages. The position of a carriage designated as a reference carriage is recorded as it moves past a motion detector. The position of each remaining carriages is recorded as they individually move past the detector. The difference between the position of a carriage and the position of the reference carriage is an offset that is added to the position reading of the carriage to accurately space the carriage form the reference carriage. Each of the carriages can have a scoring assembly that includes servomotor acting through a gear arrangement on a scoring wheel. The servomotor applies a constant load to the scoring wheel and adjusts the load for any positive or negative displacement of the scoring wheel from a reference position.
