HS-320 Pro High Speed Label Slitting and Rewinding Machine

The HS-320 Pro is a roll to roll slitting rewinding machine designed for narrow-web slitting of printed and die-cut label materials, producing several independent label rolls from one wide roll. The web is unwound from a roll up to Ø600 mm on a 3" manual shaft, guided by the ultrasonic web guide, slit by rotary or shear blades, and wound on the up and down rewinding unit – two rewinding shafts, one above the other, that take alternate lanes so neighbouring rolls do not touch.

Tension is managed at both ends: a mechanical brake on the unwind and a mechanical clutch on the rewind, with the nip roll and rewinding motors on separate VFDs. The Schneider PLC provides a meter and label counter with auto stop, so the machine halts at an exact roll length or label count. Forward and reverse winding is selected by switch, and a splicing table is fitted for joining the next roll.

200 m/min Mechanical Speed

The HS-320 Pro slits and rewinds at up to 200 metres per minute, which keeps the finishing section in step with a narrow web flexo press or rotary die cutter.

Rotary and Shear Blade Slitting

Both slitting methods are on the machine, so the operator chooses rotary blades or normal shear blades according to the material. An air blower system collects the edge trim.

Up and Down Rewinding to Ø450 mm

Two rewinding positions take alternate lanes and build rolls up to 450 mm diameter, which suits customers who want larger rolls for automatic applicators.

Core Size Selection on the Touch Screen

1", 1.5" and 3" cores are selected on the HMI, and the rewinding shafts are changeable with a collator.

Ultrasonic Electronic Web Guide

An imported ultrasonic web guide on the unwinding side keeps the web tracking straight into the knives.

Panasonic Label Counting Sensor

The counting sensor and the PLC meter and label counter stop the machine at the set count or length, giving consistent rolls every time.

Individual VFD Drives

A 1 HP nip roll/slitting motor and a 2 HP rewinding motor, each on its own Schneider VFD, hold tension steady from unwind to rewind.

Splicing Table and Forward/Reverse Winding

A splicing table lets the operator join the next roll without re-threading, and winding direction is chosen by switch to suit the customer's dispenser or applicator.

The roll is mounted on the 3" manual shaft of the unwinding unit, where the mechanical brake provides back-tension and the ultrasonic web guide keeps the edge in line. The operator positions the rotary or shear blades at the lane widths required, selects the core size and winding direction on the HMI, enters the roll length or label count, and fits cores to the upper and lower rewinding shafts.

When the machine starts, the nip roll motor pulls the web through the slitting station at the set speed while the air blower removes the trim. Alternate lanes are led to the upper and lower shafts, and the rewinding motor on its own VFD builds the rolls evenly up to Ø450 mm with the clutch controlling tension. The Panasonic sensor counts labels, and the PLC stops the machine when the target is reached. The operator removes the finished rolls, fits new cores and restarts; when the unwind roll ends, the next roll is joined on the splicing table.

• Label roll slitting – printed and die-cut self-adhesive labels slit into customer-width rolls.
• Large rolls for applicators – rolls built to Ø450 mm for automatic labelling lines.
• Blank label rolls – plain thermal and chromo stock slit and rewound on 1", 1.5" or 3" cores.
• Paper slitting – thermal paper and other paper webs up to 320 mm slit into narrow rolls.
• Rewinding and counting – re-rolling labels to exact counts after inspection or die cutting.

The HS-320 Pro handles self-adhesive label stocks on a release liner up to 320 mm wide – chromo and thermal papers and thermal-transfer papers, as well as plain paper webs. Having both rotary and shear blades lets the operator match the cut to the material. Share your stocks with RK so the knives and tension settings are set correctly before delivery.

• RK TR-320 – Slitting With Turret Rewindingthe same slitting section with an automatic turret rewinder that indexes to fresh cores without stopping.
• MS-320 – Micro SlittingRK's compact 12" micro label slitter for lighter duty on a 1 HP supply.

RK Label Printing Machinery Pvt. Ltd. has built label printing and converting machinery in Ahmedabad, Gujarat since 1995, with three manufacturing units and customers in 23+ countries. The HS-320 Pro is built with a Schneider PLC and VFDs, a touch HMI, a Panasonic counting sensor and an imported ultrasonic web guide, and it is designed to run the rolls that come off RK's own presses and die cutters. Installation, operator training and spares are handled by the team that built the machine.

• Roll size: the HS-320 Pro's up and down rewinder builds rolls to Ø450 mm. If you deliver small rolls in fixed counts and want changeover without stopping, look at the RK TR-320 turret model.
• Paper width: 320 mm maximum.
• Speed: 200 m/min – compare with the output of your press or die cutter.
• Core sizes: 1", 1.5" and 3" changeable with collator.
• Materials: rotary and shear blades are both fitted for paper work.
• Power: 3 HP single phase.
• Floor space: about 6 ft by 3.5 ft.

The price of an HS-320 Pro depends on the configuration – knives, shafts, sensor and any options added to the base machine. RK quotes prices ex-works Ahmedabad with GST at 18% applicable. Engineer travel and stay for installation and training at your site are borne by the customer. Share your roll widths, lane counts, core sizes, roll diameters and expected output, and RK will recommend the configuration and quote against it.
