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.
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.
