RK VANDANA-24 Rotary Die Cutting Machine With Sheet Cutting

The RK VANDANA-24 is a roll to roll rotary die cutting and sheet cutting machine. It uses two rotary cutting stations in sequence. Station one is a rotary die cutting unit for half cut – the die cuts the label outline while leaving the liner whole. Station two is an online rotary sheet cutting unit that cuts the web to length, and a conveyor belt system carries the finished sheets out of the machine.

Because both stations are rotary, the web runs continuously rather than stroke by stroke, and the sheet length is set on the touch screen. A Panasonic label counting sensor and a meter and sheet counter with auto stop let the operator run an exact number of sheets. When the same machine is used for roll to roll work, the slitting attachment and the up and down rewinding system (rolls up to Ø300 mm on 1", 1.5" or 3" cores) take over.

Two Rotary Stations – Half Cut and Sheet Cut

The first rotary unit kiss-cuts the labels; the second cuts the web into sheets online. Both run continuously, so the machine reaches 70 m/min or around 150 sheets per minute.

Conveyor Belt Sheet Delivery

Cut sheets are carried out on a conveyor belt system rather than dropping loose, which keeps them in order and makes stacking and counting easy for the operator.

Sheet and Meter Counting With Auto Stop

The PLC counts sheets and metres and stops the machine at the set target. A Panasonic label counting sensor is fitted for label-based counts.

Roll to Roll Mode With Slitting

For roll jobs, a slitting attachment and an up and down rewinding system are on the machine. Rewinding rolls build to Ø300 mm, in forward or reverse direction, on 1", 1.5" or 3" cores selected on the touch screen.

Large Ø800 mm Unwinding

The unwinding unit takes rolls up to 800 mm diameter on a 3" manual shaft, so long printed rolls run without frequent roll changes.

Imported Ultrasonic Web Guide

An electronic web guide with an ultrasonic based system controls paper movement on the unwinding side, keeping the web square to both cutting stations.

Schneider PLC and Touch HMI

The machine is controlled by an electronic PLC system (Schneider) with a full touch HMI (Schneider/Inovance). Sheet length, counts and core size are all set on screen.

Air Blower Waste Collection

An air blower system collects the waste trim from slitting so it does not travel into the rewind or the sheet stack.

The printed roll, up to Ø800 mm, is mounted on the 3" shaft of the unwinding unit. The ultrasonic web guide steers the web so it enters the first rotary station square. There, the rotary die cuts the label outline through the face stock – a half cut – while the liner remains continuous. The waste matrix around the labels is stripped and wound on the waste rewinding unit, leaving the labels sitting on the liner.

In sheet mode, the web then reaches the second rotary station, where a rotary knife cuts it to the sheet length set on the HMI. The conveyor belt carries each sheet out to the operator, and the sheet counter stops the machine at the set quantity. In roll mode, the second station is bypassed: the web passes the slitting attachment, the air blower clears the trim, and the lanes wind on the up and down rewinding shafts in the chosen direction until the meter or label counter reaches its target.

• Labels on sheets – die-cut label sheets for stationery, office and small-business users who apply labels by hand.
• Sticker sheets – kiss-cut sticker and decal sheets for retail, school and promotional markets.
• Roll to roll label converting – the same machine slits and rewinds die-cut labels when rolls are required.
• Short-run packaging labels – sheeted labels for packers who do not run label applicators.
• Printed roll conversion – turning printed roll stock into counted sheet packs.

The VANDANA-24 is built for self-adhesive label stock on a release liner up to 320 mm wide – chromo and coated papers, thermal papers and synthetic face stocks such as PP and PET. The ultrasonic web guide keeps clear and reflective materials on track. Die pressure and sheet knife settings depend on the material, so share your stocks with RK before the machine is configured.

RK Label Printing Machinery Pvt. Ltd. has been manufacturing label printing and converting machinery in Ahmedabad, Gujarat since 1995. The company operates three manufacturing units and supplies customers in 23+ countries. The VANDANA-24 is built with Schneider PLC, VFD and HMI components, a Panasonic counting sensor and an imported ultrasonic web guide, and it is designed to run the rolls that come off RK's own flexo presses. Installation, operator training and spares are handled by the team that built the machine.

• Sheet or roll output: if a good share of your customers want sheets, the VANDANA-24 covers both. If everything ships as rolls, a PS-320 or PTR-320 is the simpler choice.
• Paper width: 320 mm maximum.
• Sheet output rate: about 150 sheets per minute at 70 m/min – compare with your monthly sheet requirement.
• Unwind roll size: up to Ø800 mm on a 3" manual shaft.
• Rewinding needs: rolls to Ø300 mm on 1", 1.5" or 3" cores when running roll to roll.
• Power: 3 HP 3 phase supply required.

The price of an RK VANDANA-24 depends on the configuration – rotary dies and cylinders, sheet knife, slitting attachment and options. 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 label sizes, sheet sizes, materials and expected output with RK and the team will recommend the configuration and quote against it.
