DJJF: Dual Jennerjahn Fully-Automatic Surface Rewinder

DJJF: Dual Jennerjahn Fully-Automatic Surface Rewinder

The DJJF is utilized in the highest volume applications where full automation is necessary.  By sharing a few common components between two rewinders, production becomes twice that of a single JJF unit.

Description

Typical Uses:   The DJJF is utilized in the highest volume applications where full automation is necessary.  By sharing a few common components between two rewinders, production becomes twice that of a single JJF unit.  This significantly reduces a converter’s overall investment, labor requirement and production floor space.  The JJF can be used for a wide variety of converted products: point of sale, ATM, lottery ticket, airline boarding passes, pressure sensitive labels and many 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:   (In addition to the JJM, JJS and JJF features)

  1. A single core hopper and core orientation system is used to feed two individual rewinders.
  2. A core diverter monitors core needs for both machines and feeds each machine’s infeed core conveyor as required.
  3. A finished roll removal system with lane management automatically merges finished product from both machines onto one final exit conveyor.
