Label Slitting Machine

The RK TR-320 is a roll to roll slitting and turret rewinding machine for 320 mm paper width. Its turret rewinding unit indexes with a stepper motor controller and turns the rewinding shaft automatically once the label or metre counter reaches the target, so the operator does not stop the machine to change rolls. Finished rolls go up to 250 mm in diameter. The unwind takes a 600 mm roll on a 3 inch air shaft, with an ultrasonic web guide, a splicing table with paper gripper for joining paper, and mechanical brake tension control. Slitting is by both rotary and normal shear blades with an air blower for waste trimming. A 7 inch Schneider touch screen and PLC run the machine, and the mechanical speed is 100 m/min. It suits printers who run many short rolls a day and want roll changes to happen without stopping.

The HS-320 Pro is RK's high speed label slitting and rewinding machine. It slits a 320 mm web at a mechanical speed of 200 m/min and rewinds on an up and down rewinding system that takes rolls up to 450 mm in diameter. The unwind holds a 600 mm roll on a 3 inch manual shaft with the imported ultrasonic web guide and mechanical brake tension control. It has both rotary and shear blade slitting, an air blower for waste trimming, a Panasonic label counting sensor, and a 1 HP variable speed motor for the nip roll and a 2 HP motor for the rewinding unit, each on its own Schneider frequency drive. Core size is selected on the touch screen. This is the machine for large finished rolls and long runs.

The RK MS-320 is a roll to roll micro label slitter in a 12 inch size, again for 320 mm paper width. It uses normal shear blade slitting with a grooved base roll, an up and down rewinding system with mechanical clutch tension control, and a single 1 HP variable speed motor on a Schneider frequency drive. A digital counter unit counts labels and metres and stops the machine automatically. The mechanical speed is 100 m/min, finished rolls go up to 300 mm in diameter and the machine runs on 1 HP single phase power, in a footprint of about 5 ft by 4 ft. It suits small label shops and in-house label rooms that need clean slitting without a large machine.
