Kraft Masking Paper Making Machine

The SD-ZB260 slits and rewinds a mother roll of kraft paper or protective film into narrower finished rolls for dustproof and scratch-resistant covering. It is designed for converting large reels into smaller rolls used in construction, automotive painting, and appliance protection. The machine handles both kraft paper and polyethylene film, enabling a packaging producer to make its own masking rolls instead of buying them pre-made.

  • Converts large kraft paper or PE film reels into smaller rolls on site, reducing reliance on external suppliers
  • Slits and rewinds in one continuous process, so one operator can manage the line
  • Cutting speed is fixed at 100 m/min, suitable for consistent production runs
  • Automatic tension control on unwinding and rewinding ensures even roll formation
  • Two-stage electronic length counting allows accurate roll length setting and repeatable output
Problems It Solves

Why Buyers Choose It

  • Buying pre-made masking rolls adds a supplier margin and long lead times for replenishment
  • Manual slitting of kraft paper is slow and inconsistent, leading to uneven roll widths
  • Lack of control over roll length causes waste or customer complaints about short rolls
  • Inconsistent tension during rewinding leads to loose or collapsed rolls
  • Need for custom roll sizes is not met by standard off-the-shelf products
Who It Is For

Who Runs This Machine

  • Packaging converters that already buy kraft paper in large reels and want to produce masking rolls
  • Paint shops and construction firms needing on-site masking roll production
  • Automotive service centres requiring consistent protective film for vehicle painting
  • Appliance and furniture manufacturers protecting products during transit or storage
Application

Where This Machine Is Used

  • Protective packaging producers making custom-sized masking rolls for construction site use
  • Automotive workshops producing pre-cut protective film for car painting and bodywork
  • Appliance manufacturers converting kraft paper into dust covers for household goods
  • Furniture makers supplying masking rolls to paint shops for pre-assembly protection
  • Packaging converters adding a value-added slitting step to existing kraft paper inventory

Process

How The Machine Runs

Step 1Load a mother roll of kraft paper or PE film up to 1000 mm diameter onto the unwinding shaft
Step 2Guide the web through the machine using automatic tension control
Step 3Slit the web into narrower widths up to 240 mm using adjustable knives
Step 4Rewind the slitted material onto 1 inch or 3 inch cores with tapered ends
Step 5Set the target roll length using the two-stage electronic counter before starting

Materials

  • Kraft paper reels up to 450 mm wide and 1000 mm diameter
  • Environmental polyethylene (PE) film for protective covering
  • HDPE film as an alternative for durable, waterproof protection
  • Optional pre-taped masking film using adhesive tape applied inline

Quality Control

  • Automatic tension control prevents slack or over-tension during unwinding and rewinding
  • Electronic length counter verifies roll length before the machine stops
  • Machine is tested with customer material before shipment to confirm slitting accuracy
  • Core taper and diameter match ensure secure roll mounting and no slippage

Customisation

  • Cutting width can be adjusted to produce rolls under 240 mm if needed
  • Core diameter can be supplied in 1 inch or 3 inch to match existing core stock
  • Taper width can be adjusted to 16 mm for 3 inch cores to ensure tight fit
  • Pre-tape application unit can be added for adhesive-backed masking film
  • Power supply can be built to match voltage and frequency of destination country

Certifications

  • ISO9001:2000 certificate obtained in 2005
  • CE certificate obtained in 2006
Comparison

How It Compares

Buying pre-made masking rollsConverting in house removes the supplier margin but requires inventory of mother rolls and machine investment
Manual slitting with hand toolsThis machine ensures consistent width, even tension, and accurate length, reducing waste and rework
General paper slitting machinesThis machine includes automatic tension control and electronic length counting, which are not standard on basic models
Use Guide

Running It On Your Floor

  1. Ensure the unwinding shaft is fitted with a 1 inch or 3 inch core before loading the mother roll
  2. Set the desired final roll width using the adjustable slitting knives
  3. Start the machine at low speed and increase gradually to 100 m/min once the web tracks steadily
  4. Verify the first few meters of slitting for width accuracy and edge quality
  5. Use the two-stage length counter to set the target roll length before starting a new run
