In industry packages are manufactured by machines.
They are first designed on a computer system using COMPUTER AIDED DESIGN
software (CAD). A net / development can be drawn more accurately by CAD
software and also checked, with faults can be corrected before any
material is cut, Small companies use software such as Techsoft 2D
design, Coral Draw or other specialist software.
A company called ‘Roland’ manufacture a range of machines that are computer controlled. They are capable of cutting out accurate nets and even scoring the fold lines, making it easy to fold the net together. A simplified version of one of these machines is seen below.
Roland produce a series of machines called STIKA
machines. These are basically used for cutting out adhesive backed
lettering for signs and logos (Material called 'sticky backed vinyl'). However, larger versions can be used to
cut out nets / developments from a range of card. The small hardened steel cutter is held
firmly in a tool holder. The tool holder moves up and down a slide,
following the design. The paper/adhesive laminate is fed into the
machine automatically. As the tool holder moves the cutting tool is
pressed into the material, cutting the desired shape. (Click

|4. The computer (including software), vinyl cutter and manufactured package, can be viewed as a Systems Diagram, see below. Systems diagrams are divided into three aspects/stages - INPUT - PROCESS - OUTPUT. The systems diagram below, describes what happens at each stage, from the design to manufacture of a simple package.|
