About The JTS-2 Turret Slitter
The JTS-2 is a two-station turret center winder. While cores are being loaded onto the shaft in station 1, adhesive tape is applied to the cores. As the turret rotates the shaft from station 1 to station 2, the tails are cut. A nip roller makes contact with the leading edge of the web momentarily at the beginning of the cycle to assure a quality roll start. The finished roll’s rotation is driven by the center of the rewind shaft to minimize contact with the surface of the roll for web sensitive products. As the turret rotates the finished rolls back to station 1, the rolls are sealed with an adhesive tab and stripped from the shaft. A new set of cores are loaded onto the shaft in station 1 while a new set of finished rolls are being wound in station 2.
The most common master roll widths for the JTS range from 36 to 65 inches. Typical rewind shafts are 2 or 3 inches in diameter with finished roll diameters up to 10 inches.
Driven unwind stands and load cells can be added for very low-tension applications. Banding systems can also be added to eliminate end-of-roll waste caused by adhesive residue or tearing of the product when the roll is opened by the end user.
Also available as an option, robotic core I.D. and R.F.I.D. labeling systems can be integrated.
Jennerjahn’s JTS-4 4 shaft turret center winder is another center winder option for high volume, fully automatic production.
Applications
The JTS-2 is a fully automatic turret winder used to convert a variety of surface sensitive products. The machine is ideal for converters who seek full automation, but who have concerns about web surface scratching or require minimum wound-in tension. The machine’s sophisticated tension control system provides superior lane control, allowing for multiple slit production. This machine converts window tint films, coated photo papers, pressure sensitive cast vinyl, coated canvas and much more.
Operator Responsibilities per Cycle
The machine is fully automatic, allowing the operator to assist with roll packaging.
Automation
Cores are staged in a core hopper and transferred to an autoloader station where they are loaded onto rewind shafts. The machine automatically cuts the tails, wraps the tails around the cores, tucks the tails, winds the roll to the desired length, seals the tails of the finished rolls and strips the shaft of finished rolls.
