Abstract
A score knife positioner includes a carriage bracket having a locating tab for receiving a score knife assembly. Linear bearings are attached to the carriage bracket and are configured to engage with a pair of guide rails. The linear bearings are each staggered with respect to linear bearings of adjacent carriage brackets and located so that score knife positioners on either side of a particular score knife positioner can be nested together. The carriage bracket has a width less than a width of the score knife assembly and allows adjacent score knife assemblies to be positioned so that there is less than one-half inch between score knifes. Score knife positioners can be moved to a desired location and locked into place via a carriage brake attached to the carriage bracket.

An apparatus comprising:
- a first carriage assembly comprising:
- a carriage bracket having a linear bearing;
- a score knife holder;
- and
- a score knife in the score knife holder;
- a second carriage assembly comprising:
- a carriage bracket having a linear bearing;
- a score knife holder;
- and
- a score knife in the score knife holder;
- a third carriage assembly comprising:
- a carriage bracket having a linear bearing;
- a score knife holder;
- and
- a score knife in the score knife holder;
- a first guide rail having a flat surface, the first carriage assembly engaging the flat surface of the first guide rail via the linear bearing of the first carriage assembly;
- and
- a second guide rail having a flat surface, the second guide rail parallel to the first guide rail, the second carriage assembly engaging the flat surface of the second guide rail via the linear bearing of the second carriage assembly;
- and
- a third guide rail having a flat surface, the third guide rail parallel to the first guide rail, the third carriage assembly engaging the flat surface of the third guide rail via the linear bearing of the third carriage assembly;
- wherein the linear bearing of the first carriage assembly, the linear bearing of the second carriage assembly, and the linear bearing of the third carriage assembly are each staggered with respect to linear bearings of adjacent carriage assemblies to allow the first carriage assembly to nest with the second carriage assembly and the second carriage assembly to nest with the third carriage assembly, the score knife of the first carriage assembly being less than one-half inch from the score knife of the second carriage assembly when the first carriage assembly is nested with the second carriage assembly, and the score knife of the second carriage assembly being less than one-half inch from the score knife of the third carriage assembly when the second carriage assembly is nested with the third carriage assembly, and
- wherein each carriage bracket has a tab configured to engage inner surfaces of opposing walls of a respective score knife holder.
