Coreless Fully-Automatic Surface Rewinder – CJJF
Coreless Fully-Automatic Surface Rewinder – CJJF
The Next Generation POS Roll and POS Roll Rewinder is here. The CJJF model maintains the highest level of automation as the JJF, however it utilizes Jennerjahn Machine’s patented coreless rewind technology.
Product Description
The JJF model is the highest level of automation featured on all Jennerjahn small roll surface rewinders. Automation levels include; Semi-Manual, Semi-Auto, and Fully Automatic.
The JJF requires minimal operator involvement to keep the machine running in a fully-automatic mode. This model minimizes labor while increasing productivity and product quality.
Jennerjahn’s shaftless rewind technology replaces outdated and inefficient rewind mandrel systems by using easily interchangeable chucks for various core diameters to secure the cores during the winding cycle. After winding, the tails are automatically cut and secured to the roll using the standard glue system or an optional adhesive tab sealing system. The finished rolls are then transferred by conveyor to a packing table or to an optional roll processing line and JCP roll packaging line.
The separate unwind stand and rewinder frame offer greater flexibility add optional features such as adhesive tab tail sealing, dual web or Jennerjahn’s patented coreless technology.
All Jennerjahn small roll surface rewinders feature two bedrollers and a top rider roller that applies programmable torque and regulated down pressure to accurately control tension and roll hardness throughout the winding cycle.
High quality, precision ground solid shafts eliminate core-related product quality issues. An automated shaft handler transfers and positions shafts from the roll stripping station to the winding station. Jennerjahn’s innovative coreless rewind technology utilizes similar chuck tooling as the JJF to secure the shaft during the winding cycle. After winding, the tails are automatically cut and secured to the roll using the standard glue system or an optional adhesive tab sealing system. The finished rolls are then stripped from the shaft and transferred to the exit conveyor. The CJJF continues to run in a fully automatic mode as the shaft handler picks up the shaft and stages it for the next cycle.
Advantages of coreless rolls include; the elimination of core costs, inventory space and environmental issues with core waste. Jennerjahn Machine’s patented coreless POL rolls are more than twice as resistant to crush than honeycomb cored POS rolls.
Customers with an existing JJS, JJF or DJJF manufactured in the year 2000 or later can take advantage of this patented coreless rewind technology by adding a retrofit to their machine.
A license to use this specific machine to produce coreless POS rolls is required. The machine and the coreless rolls it produces are covered by the following US patents. US 10,759,622 B2, US 10,759,623 B2, US 10,759,624 B2 and US 10,759,625 B2.
