Tri-O 50 CAL

First step for calendar production

  • Punching width : up to 500mm (20″)
  • Punching thickness : up to 1.5mm
  • Binding thickness : up to 28.5mm
  • Punching output : up to 8,000 sheets / hour
  • Binding output : up to 200 documents / hour

All above outputs are based on 80gsm plain paper and will vary pending on the nature of the document, the operator skills, the work organisation. Best punching quality is obtained with paper thickness not exceeding 1.5mm


Like the Tri-O 34 & 50, the Tri-O TO CAL is a simple table top ALL-IN-ONE manual machine that is particularly convenient for those making small runs of calendars or various prototyping works.

With just ONE machine, you can :

  • punch 3:1 round holes open edge,
  • punch 3:1 round holes with thumb cut open edge,
  • Wire-O® closing from 3/16” to 1-1/4” open edge

All punch pins can be easily disabled for custom punch patterns (all pins being the same length, no re- positioning difficulty).
