Abstract

A process for cutting column and row gutters on multilayer signage media into individualized signage cards includes placing pre-die-cut slits at predetermined locations within the column gutters to assist a cutter in cutting completely through the multilayer signage media.

First claim

What is claimed is:

1. A method for cleanly separating cards cut from adhesive signage for store shelving, comprising:
providing separate and individual sheets of adhesive signage with each of said individual and separate sheets having column and row gutters;
providing prearranged longitudinal slits within said column gutters;
placing each of said separate and individual sheets of adhesive signage onto a conveyor belt;
providing a first cutter, said first cutter including a rotary blade;
feeding said separate and individual sheets of adhesive signage into said first cutter for cutting said sheets of adhesive signage along said row gutters;
moving said rotary blade into a groove in a stationary member for engagement with said separate and individual sheets of adhesive signage;
lifting said rotary blade away from said groove of said stationary member after cutting each of said row gutters;
providing a second cutter and aligning said second cutter with said prearranged longitudinal slits and cutting said separate and individual sheets of adhesive signage along said column gutters and through said prearranged longitudinal slits;
and
using said prearranged longitudinal slits to create stress concentration points in said separate and individual sheets of adhesive signage in order to back up blade initiated portions of said cutting of said separate and individual sheets of adhesive signage along said column putters such that if said blade initiated portions of said cutting of said separate and individual sheets of adhesive signage along said column gutters fails to initiate a clean cut at a bottom of said cards said prearranged longitudinal slits will ensure full separation between said separate and individual sheets of adhesive signage and said gutter columns by said second cutter at said prearranged longitudinal slits.

2. The method of claim 1 , wherein said prearranged longitudinal slits in said separate and individual sheets of adhesive signage are between cards on said separate and individual sheets of adhesive signage.

3. The method of claim 2 , wherein said second cutter has blades adapted to cut through a bottom surface of said separate and individual sheets of adhesive signage within said column gutters to create multiple cards.

4. The method of claim 1 , including cutting said separate and individual sheets of adhesive signage with said second cutter in a direction orthogonal to cuts provided in said separate and individual sheets of adhesive signage by said first cutter.

5. The method of claim 1 , including providing said prearranged longitudinal slits in each of said separate and individual sheets of adhesive signage as a first cut before said separate and individual sheets of adhesive signage reach said first cutter.

6. The method of claim 1 , wherein first cutter provides second cuts to said separate and individual sheets of adhesive signage.

7. The method of claim 6 , wherein said second cutter provides third cuts to said separate and individual sheets of adhesive signage.
