Basic modules of the inserting system SI 5250

Inserting system SI 5250

  • Even the smaller system offers a surprising flexibility and numerous possibilities of document processing.

  • The towerfeeder - the heart of the system – has already 4 feeding stations for documents, enclosures or envelopes up to size C4
  • The inserting system SI 5250 is controlled and programmed at an operating panel with coloured display. It supports the user with graphics, drawings and texts so that the user is always informed about the current status and condition of the system
  • 24 different jobs can be stored
  • The maximum speed is up to 4.300 strokes/ h


  • The folder can be adjusted electronically to the fold types single, wrap, Z- and double parallel fold. With the wrap or Z-fold up to 8 sheets can be processed
  • With the help of an electronic control system you can even use different fold types within one job 

Variable applications – strong and fast – short set-up times – extendable with modules

A compact, flexible and professional inserting system should be able to handle a high number of tasks and requirements, such as:

  • Mailings, invoices, reply notes or enclosres - folded and unfolded - are to processed with different envelope sizes from C6/5 up to C4 
  • The adjustment to different envelope sizes should be possible without having to make changes at the inserting system.
  • Personalized outgoing mail should be inserted fully automatically with a control character code - such as a barcode
  • It should be possible to control individual documents/sets in case of unclarities
  • When changing a job the set-up times should be rather short
  • A system should be modular extendable for possible further demands in the future

The HEFTER Systemform inserting system SI 5250 is the solution for this challenging task. It stands on a vertically adjustable table.


Further options:

  • Intelligent operation with character codes
  • High volume feeding station for documents 
  • Separation kit for feeding station
  • Conveyor stacker
  • Franking machine connection
  • Franking machine kit
  • C4 sealing unit
