Servo Core Cutting Machine – Fully Servo Controlled Digital Auto Paper Core Cutter

It is an automatic paper core cutter in which the cutting cycle is under servo and digital control rather than the operator's hands. A full length core is loaded on the 500 mm shaft. The cut widths are set on the operator HMI and the machine adjusts to them automatically, with no spacers and no manual setting. The digital timer auto control then runs the cycle for the set duration and stops. The cut itself is performed pneumatically.

Because the control is digital and the motion is servo based, the machine gives the same result cycle after cycle, regardless of who is operating it. It handles the three standard core diameters used in label, tape and paper converting, 1, 1.5 and 3 inch, and runs on an ordinary single-phase supply, which makes it easy to place anywhere in the plant.

Fully Servo Control With Digital Auto Cycle

The cutting cycle is servo controlled and started, timed and stopped digitally. The operator loads the core and starts the cycle; the machine does the rest.

Pneumatic Cutting Action

The blades are brought into the core pneumatically, so the cutting force and depth are consistent and the operator does not apply any physical effort to the cut.

Core Cutting Attachment

The cutting attachment is supplied to suit the cores you cut, so the machine arrives set up for the core sizes you actually cut rather than a generic set.

1 inch, 1.5 inch and 3 inch Core Sizes

The three core diameters used across label rolls, thermal paper rolls and tape rolls are all covered on the same machine.

500 mm Core Shaft With 450 mm Working Length

Standard parent cores fit on the shaft, and up to 450 mm of that length is cut in one cycle, giving several finished cores per loading.

1 HP Single-Phase Motor With Digital Timer

The machine runs on a 1 HP single-phase motor controlled by a digital timer with auto control. Single-phase supply means no special wiring is needed at the installation point.

Compact Footprint

At about 4.7 ft long, 2.5 ft wide and 4 ft high, the machine fits beside a slitter or rewinder without taking production floor space.

The widths are set on the operator HMI and the machine adjusts to them automatically, and the cutting duration is entered on the digital timer. The operator slides a parent core, up to 450 mm of working length, on to the core shaft and starts the cycle. From that point the machine is in control: the servo drive rotates the core, the pneumatic system brings the blades into the core and the cut proceeds for the timed duration.

When the timer completes, the blades withdraw and the cycle stops automatically. The operator removes the cut cores, loads the next parent core and starts again. Because the widths are adjusted automatically and the cycle is digitally timed, every core leaves the machine at the same size, and a new operator can be trained on the machine in a short time.

• Label converters – cores for slit self-adhesive label rolls in many widths per day.
• Thermal paper and POS roll producers – 1 inch and 1.5 inch cores in high daily volumes.
• Tape manufacturers – 3 inch and smaller cores for BOPP and other tape rolls.
• Paper and film slitting units – core preparation for every slit width without measuring and hand cutting.
• Packaging plants – in-house cores for rewinding lines, cut to size on demand.

The machine is built for paper cores of 1 inch, 1.5 inch and 3 inch inside diameter, as used for label stock, thermal paper, tapes and film rolls. If you run a different core diameter or an unusually heavy wall, share the core sample with RK so the cutting attachment can be made to suit it.

• Automatic Core Cutting Machine (RK PCC)pneumatic paper core cutter with rotary blades, spacer set positions and auto unloading.
• Manual Core Cutting Machine (RK MCC)motorised rotary blade core cutter with manual cutting for lighter workloads.
• Label Slitting With Up and Down Rewindingthe high speed slitter rewinder that consumes these cores.

RK Label Printing Machinery Pvt. Ltd. has been manufacturing label printing and converting machinery in Ahmedabad, Gujarat since 1995, with three manufacturing units and customers in 23+ countries. RK builds core cutters at three levels, manual, pneumatic automatic and servo, so a converter can choose by daily volume rather than buying more or less machine than needed. Every core cutter is made alongside RK's slitters and rewinders, so the cores match the rolls they will carry and one manufacturer supports the whole line.

• Core diameters: confirm that 1, 1.5 and 3 inch cover everything you use.
• Parent core length: the shaft is 500 mm with a 450 mm working length.
• Daily core count: for an occasional core, the manual RK MCC is enough; for a steady flow across shifts, the servo machine gives repeatability with no operator effort.
• Width consistency: if every roll width must be exact, a servo controlled, digitally timed cycle is the safer choice.
• Power supply: this machine runs on 1 HP single-phase, useful where a three-phase point is not available nearby.
• Compressed air: the pneumatic cutting action needs an air supply at the machine.

The price of the RK Servo Core Cutting Machine depends on the core cutting attachment supplied for your sizes and any other configuration you require.
