Abstract

A method and associated system are provided for producing a perforation line between adjacent lottery tickets in an automated production line wherein a substrate having lottery tickets printed thereon is conveyed through a perforation station in the production line. A perforation machine in the line is controlled to define a perforation line between the adjacent lottery tickets. The controlling process includes inputting control variables into a controller associated with the perforation machine, the control variables relating to conditions that determine a desired perforation profile of the perforation line. The controller programs the perforation machine with a specific perforation profile for the perforation line that is generated based on the entered control variables, and changes the perforation profile upon inputting of different values for the control variables. The perforation profile is specifically tailored to the control variables between different ticket production runs, or between tickets in the same ticket production run.

First claim

What is claimed is:

1. A system for producing a perforation line between adjacent lottery tickets in an automated production line wherein a substrate is conveyed through a perforation station in the production line, the substrate having individual lottery ticket indicia printed thereon such that a continuous stream of adjacent lottery tickets oriented end-to-end are conveyed through the perforation station, the system comprising:
a perforation machine at the perforation station to produce a perforation line between the adjacent lottery tickets;
a controller in communication with the perforation machine, wherein the controller is configured to:
receive inputted control variables that relate to conditions that determine a desired perforation profile of the perforation line;
program the perforation machine to produce the perforation line with a specific perforation profile based on the entered control variables;
reprogram the perforation machine with a different perforation profile upon receipt of different values for the control variables; and
wherein the control variables relate to environmental conditions expected at a dispensing location for the lottery tickets being produced and the perforation profiles are changed between different ticket production runs, or between tickets in the same ticket production run based on changes in the environmental conditions.

2. The system according to claim 1 , wherein the control variables are one or both of temperature and humidity at the dispensing location.

3. The system according to claim 1 , wherein the control variables relate to a combination of the environmental conditions expected at the dispensing location of the lottery tickets and characteristics of a substrate stock on which the lottery tickets are printed in the production line.

4. The system according to claim 1 , further comprising an electronic library of different pre-generated perforation profiles for specific values of the control variables, the controller in communication with the library, wherein the controller selects one of the pre-generated perforation profiles that is a closest match for the input control variables.

5. The system according to claim 4 , wherein the controller further modifies the selected pre-generated perforation profile based on the input control variables.

6. The system according to claim 1 , wherein the perforation machine is a laser perforation machine having one or more laser perforation heads that are controlled by the controller for producing the different perforation profiles.
