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 offset from one another 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.
Claims14
A carriage assembly comprising:
- a carriage bracket having a linear bearing attached thereto, a score knife holder holding a score knife attached thereto, and a brake plate groove;
- and
- a brake assembly comprising:
- a brake piston comprising a foot extending from a common member perpendicular to the foot, the foot located substantially in a same plane as the score knife;
- and
- a brake return spring located between the brake piston and the carriage bracket;
- wherein the foot of the brake piston is extendible through a first surface of the brake plate groove toward a second surface of the brake plate groove to contact a flexible brake plate located in the brake plate groove, a surface of the foot opposite the second surface being substantially parallel to the second surface, the brake return spring opposing movement of the brake piston toward the second surface.
A carriage assembly comprising:
- a carriage bracket having a plurality of linear bearings attached thereto, a score knife holder holding a score knife attached thereto, and a brake plate groove;
- and
- a brake assembly comprising:
- a brake piston comprising a plurality of feet extending from a common member perpendicular to the plurality of feet, the feet spaced apart from one another and located substantially in a same plane as the score knife;
- and
- a brake return spring located between the brake piston and the carriage bracket;
- wherein the plurality of feet of the brake piston are extendible through a first surface of the brake plate groove toward a second surface of the brake plate groove to contact a flexible brake plate located in the brake plate groove, a surface of each of the plurality of feet opposite the second surface being substantially parallel to the second surface, the brake return spring opposing movement of the brake piston toward the second surface.
