Successful Round-Cornered Products

Following these five tips will help your Challenge Machinery customers avoid many mistakes that commonly occur when working with round-cornering equipment:

  • Keep the knife and die sharp and in good alignment. Dull knife and other poor adjustments lead to irregular cuts. Carefully sharpen knives with a 35-degree bevel and finely hone them (#32 micro cut or better) to remove coarseness and burrs.
  • To ensure good corners, always firmly place paper against the left and back guides.
  • Are you experiencing unusual noises and irregular action when you run your machine? A maintenance check is probably due. Have your machine checked by a qualified person.
  • Exercise care when handling and changing the knives.
  • NEVER leave the machine running unattended!
