About The Standard JLS Large Slitter Rewinder

This fully automatic large roll slitter rewinder utilizes two bedrollers and a top rider roller that applies programmable torque and regulated down pressure to accurately control tension and fundamental winding technology throughout the winding cycle.

From a shaftless unwind stand the web goes through a dancer tension control system providing superior tension control during rapid accels and decels.  A bowed roller spreads the web prior to slitting using shear, razor, or score cutting methods.

Cores ranging from 1.18 to 3.50 inches in diameter are automatically fed from a standard table or optional hopper into the core loader, and placed into the winding station.  Jennerjahn’s shaftless rewind technology replaces outdated and inefficient rewind mandrel systems by using easily interchangeable chucks for various core diameters to secure the cores during the winding cycle.  Roll starts are achieved with a tuck blade for non-adhesive starts or transfer adhesive applied automatically to the core.

After winding, the tails are automatically cut and secured to the roll by glue or adhesive sealing tabs.  The finished rolls from 2.5 to 18 inches in diameter are then transferred by conveyor to a packing table or down-stream roll processing equipment.

The JLS can be modified and equipped with numerous options, special features and custom specifications.
