Centre Folding Devices

Centre folders facilitate the continuous longitudinal folding of an in-fed sheet. A wide variety of such devices are available, together with a multitude of related accessories to facilitate specialised bag production.

Types and options for centre folders include:

• Optional tip-type bottom gusset former, complete with full hand wheel adjustments
• Single or dual lip folders, with optional longitudinal or rotary sealer/s
• Electric lateral adjustability of centre folder
• In-Line Centre Folders.
  • Whereas conventional centre folders necessitate the mounting of the film roll to be at 90 degrees relative to the ultimate direction of web processing, in-line centre folders allow the film roll to be mounted directly behind the production line. Features of these devices include:
    • Floor space minimisation
    • Integrated, servo edge guided air cushioned turning bar
    • Hand wheel adjustability of out-feed nip rollers separation and translatio
  • Both horizontally oriented and vertically oriented configurations can be supplied.
    • Horizontally oriented in-line centre folders are invaluable for the processing of heavy gauge films and laminates because the out-fed centre-folded web horizontally exits the folder.  Consequently, the web does not traverse around any rollers, avoiding crease formation.
    • Vertically oriented in-line centre folders maximise the available space for subsequent special purpose attachments.
