RK 3040-D Roll to Roll Label Die Cutting Machine

The RK 3040-D is a high speed label die cutting machine in flatbed (platen) form. A flat steel die is mounted in the cutting unit and the web is fed forward stroke by stroke; on each stroke the die presses into the material, cutting the label shape through the face stock while leaving the liner intact. Because the web is pulled by a servo motor, the feed length is accurate from the first stroke to the last, which is what keeps the labels correctly placed on the roll.

The machine is designed for large quantities of barcode labels, blank labels and any other label that needs die cutting from a roll. It runs smoothly, needs little maintenance, and the touch-screen interface keeps operation simple for a regular machine operator. The dedicated modules for plain and printed labels, together with the sliding re-pass scanner, make changeover between job types quick.

300 mm x 400 mm Flatbed Die Cutting Unit

The cutting area is 300 mm wide with a repeat length of up to 380 mm, on a maximum paper width of 320 mm. That covers most pharma, FMCG, logistics and barcode label formats produced on narrow web presses.

Servo-Controlled Paper Pulling

The web is advanced by an electronic servo motor (Schneider). Servo pulling gives exact feed length on every stroke, so label pitch stays consistent and cutting stays in register with the print.

Re-Pass Scanner With Sliding Assembly

For printed labels, the re-pass scanner reads the print mark and the sliding assembly lets the operator position it quickly. The machine then cuts each label exactly where the print was placed.

Separate Plain and Printed Label Modules

The 7" touch HMI has one module for plain label die cutting and one for printed label die cutting. The operator selects the mode on screen instead of re-setting the machine mechanically.

Online Waste Matrix Rewinding

The waste skeleton left after cutting is rewound online on a clutch-controlled unit, so the finished roll comes out clean and the operator does not stop to clear waste.

Dancer Roller With Sensor Feedback

A dancer roller with an analog output sensor keeps web tension steady between unwinding and cutting, which protects thin face stocks and keeps the cut position stable.

Auto Unwinding and Rewinding on 3" Shafts

Both unwinding (up to Ø600 mm roll) and rewinding are motorised, each with its own 1 HP AC motor, and tension is controlled by a mechanical brake on the unwind and a mechanical clutch on the rewind.

The printed or plain roll is loaded on the 3" unwinding shaft. The gauge unit guides the web sideways and the mechanical brake holds back-tension while the 1 HP unwind motor releases paper as the machine calls for it. The web passes over the dancer roller, whose sensor feeds tension information back to the drive, and then into the servo pulling unit. In printed label mode the re-pass scanner reads the print mark on the web; in plain label mode the operator simply enters the feed length on the HMI.

At each stroke the servo pulls the web forward by the set length and the flatbed unit presses the die through the face stock. The cut labels stay on the liner while the surrounding matrix is lifted away and wound on the online waste rewinding unit. The finished roll of die-cut labels winds on the 3" rewinding shaft, with the clutch keeping the roll firm and even. Speed is set on the HMI within the 12,000 to 18,000 strokes per hour range, depending on repeat length, material and die shape.

• Barcode labels – blank and pre-printed barcode label rolls for logistics, retail and warehousing.
• Plain label rolls – blank self-adhesive labels supplied to thermal and thermal-transfer printer users.
• Printed product labels – die cutting flexo or digitally printed labels in register using the re-pass scanner.
• Pharma and FMCG labels – short and long runs of regular label shapes in 300 x 400 mm format.
• Stickers and decals – kiss-cut stickers where the face is cut and the liner stays whole.

The RK 3040-D is built for self-adhesive label stocks on a release liner – chromo paper, thermal paper, thermal-transfer paper and synthetic face stocks such as PP and PET, up to a paper width of 320 mm. Since die pressure and stroke rate depend on the material and die shape, share your actual stocks with RK before the machine is configured.

• RK 3040-S – Die Cutting With Sheet Cuttingthe same flatbed die cutter with a sheet cutting option for roll-to-sheet output.

RK Label Printing Machinery Pvt. Ltd. has been manufacturing label printing and converting machinery in Ahmedabad, Gujarat since 1995. The company runs three manufacturing units and supplies customers in 23+ countries. The RK 3040-D uses Schneider servo, VFD and HMI components, and it is built alongside RK's own flexo presses, slitters and inspection machines, so the die cutter is matched to the rolls your press actually produces. Installation, operator training and spare support come from the same team that built the machine.

• Label size: the cutting area is 300 mm wide by 380 mm repeat – check your largest label layout fits inside it.
• Paper width: maximum 320 mm; match this to your press and roll widths.
• Plain or printed: if you cut both, the separate HMI modules and re-pass scanner on the 3040-D save changeover time.
• Output required: 12,000 to 18,000 strokes per hour with several labels per stroke – work out labels per hour from your die layout.
• Finishing needed: if you also need sheet delivery, look at the RK 3040-S instead.
• Roll sizes: unwinding up to Ø600 mm on 3" cores.

The price of an RK 3040-D depends on the configuration chosen – shaft type, scanner, die sets 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. Send RK your label sizes, materials, roll widths and expected output and the team will recommend the right configuration and quote against it.
