Case Studies

We've not had any curly problems for months, that's due to the improvements we made in the storage of board  Mick Walton, Cutting Operator

What was limiting the speed of the gluing lines?

Curly board was a problem for Medica for many years. It affected printing, cutting and gluing lines causing downtime, slow running and waste.


  • Board doesn't feed
  • Double sheets get fed
  • Machine cuts out


  • Incorrect colouration in print causing internal waste
  • Potential damage to tooling

Curly board in the past has been problematic; the feed could be stop-start. Tim Standing, Production Manager

How did the Cutting Team tackle the problem?

The Growth Through Excellence team used Chartwell's best in class problem solving methodology to discover the root cause of the curly board problem:

  • A device was created so the team could accurately test and compare the curl of individual sheets of board
  • Board curl was measured under different conditions
  • Board manufacturers were contacted so the team could better understand their process

The structured approach allowed the team to work methodically to understand and solve the previously described "impossible problem".

What were the results?

Curly board is now a distant memory for Medica. The Growth Through Excellence team has continued to monitor curly board but have not seen any issues.

With the implementation of the team's improvement idea feeding the board is now not an issue." Tim Standing, Production Manager
