Description

Typical Uses:   The JJF is utilized in high volume applications where full automation is necessary.  The JJF is very versatile and can be used for a wide variety of converted products.  Some roll types include point of sale, ATM, lottery ticket, airline boarding passes, pressure sensitive labels and much more.

Operator Responsibilities Per Cycle:   None!

Automation:   Cores are automatically fed into a sorting unit where they are aligned and staged in the autoloader.  The machine inserts the cores into the rewinding station, cuts the tails, wraps the tails around the cores, tucks the tails, winds the roll to the desired length, transfers the rolls to the seal station, seals the tails of the finished rolls, transfers the rolls to an exit conveyor and conveys the rolls outside of the machine.

Standard Features:

  1. PLC and Touch Screen HMI
  2. Recipe Screens
  3. Diagnostic Screens
  4. Automatic acceleration and deceleration calculations based on master roll diameter and material type
  5. Automatic brake puck selection based on roll diameter
  6. VPN for remote diagnostics
  7. Electronic side lay to allow for “touch of a button” unwind roll alignment at the front of the machine
  8. Large core hopper to automatically fill the core sorting unit as required.
  9. Core sorting unit to orient cores for insertion into the rewinding station.
  10. Automatic core insertion system
  11. This machine incorporates a shaftless rewind system eliminating the need for a complex mandrel management system. The result is a more efficient design with far less maintenance requirements than traditional shafted offerings
  12. Automatic tail tucking system for 9/16” to 3.5” OD cores. (14mm to 89mm)
  13. Automatic tail cutter
  14. Automatic gluing system (optional tabbing unit is available)

Optional Features

Small Roll Kick-Out Assist & Roll Catch:  The small roll kick-out assist feature is used on the tail tuck mechanism when running small diameter rolls.  At the end of a cycle, the tuck bar assembly automatically pivots the tuck blade to the correct angle and extends into the nip point to assist during the roll eject sequence.  A Roll Catch feature in the seal station utilizes a plate to engage in the seal bed roll station and allow the small wound rolls the travel from the winding station to the seal station and stay aligned.
