Wohlenberg Three-Knife Trimmers

  • Proven one piece machine frame cast provides long-lasting cutting accuracy
  • Incorporation of ‘Dynamic-drive Technology’ aids automated operation
  • Clutch-free drive concept for less machine ‘wear & tear’ and reduced maintenance
  • Quick-change system for front and side knives
  • Step-less motorised adjustment of product position during operating cycle
  • ‘Navigator’ operating concept allows complete size input via touch screen for simple job setting up

Dynamic and economical are just two of the words to describe the outstanding features that characterise Wohlenberg’s high speed trim-tec 60i three-knife trimmer. The inclusion of a new no-clutch drive concept with highly dynamic servo assist, in combination with the reliable and robust, cast-in-one-piece machine frame, provides the user with the smoothest of operations and, at the same time, maximum machine output. In operation, books are transported carefully (without jerking) through the stations via a book transport system that requires no conveyors. Even minimum measure deviations can be steplessly adjusted during on-going production. A cam-shaped swinging shear cut optimises the trimming quality and minimises the cracking of printing ink at the cutting surface. The machine is able to accelerate within a second from 0 to 60 cycles without leaving any marks on the products.

Optional system extensions:

  • Wireless keyboard for the input of alpha-numeric job data and text
  • Connection funnel for off-cut suction and for linking with the off-cut disposal system
  • Off-cut conveyor for off-cut transport from chute into a container
  • Small format device

This is an in-line high speed three-knife trimmer with integrated counter stacker for perfect binding systems in the upper speed range. One of the key features of the trim-tec 90e is the inclusion of new dynamic drive technology, by which a considerable performance increase and significant reduction in set-up time can be realised. This is a great contribution to increased efficiency of the total perfect binding system. Visible proof of this new technology is the new design of the three-knife trimmer, which takes ergonomic knowledge into account, thus reducing the operator’s workload.

Optional system extensions:

  • Wireless keyboard for the input of alpha-numeric job data and text
  • Smart NaviDesk, an integrated measuring system for easy and precise format recording
  • Small format device
  • Large format device
