Product catalog summary

Company Overview and Innovation

SML Maschinengesellschaft mbH, headquartered in Lenzing, Austria, specializes in high-performance extrusion equipment with over 40 years of experience. The company is recognized for technological leadership, holding multiple patents and awards including the Austrian Federal Award for Innovation. SML focuses on delivering turnkey extrusion lines worldwide with a strong emphasis on innovation and customer satisfaction.

High-Speed Coating Lines

These lines are designed for industries requiring high production volumes and large lots, such as paper converters, flexible packaging producers, and technical film manufacturers. Key features include:

  • Fully automatic unwinders with large roll diameters and splicing at full line speed
  • High-speed winders (e.g., SML W1100, W2000 series)
  • On-demand inline part bobbin cutting
  • Three-roller laminators with easy roll exchange and modern drives
  • Mono- or co-extrusion units with movable extruder frames for easy access
  • Automatic thickness gauging systems with multiple measurement frames
  • Bobbin handling systems integrated for unwinders and winders

Special components like corona treatment and web inspection can be integrated. The lines achieve speeds up to 600 m/min, focusing on quick start-up and fast product changes to minimize waste and maximize productivity.

Coating Lines for Extra-Wide Products

Designed for technical applications such as roofing membranes, tarpaulins, and scaffold sheeting, these lines handle widths of 4.5 meters or more. Due to the nature of heavy materials like woven fabrics and nonwovens, speeds are lower but output is increased by width. Features include:

  • Manual or semi-automatic unwinders with splice at reduced speed or accumulator use
  • Focus on quick, waste-saving product changeovers
  • Robust machine design to handle high process tensions of thick products

Coating Lines for Packaging Applications

SML offers highly customizable lines tailored to customer needs, including space constraints and third-party components. Modular design allows for future upgrades. Combined cast film and lamination lines integrate extrusion coating inline, offering advantages such as:

  • Improved waste management by recycling uncontaminated edge trims
  • Process flexibility allowing station-by-station product specification changes

These combination lines are used for PA/PE barrier films and PET/PE sealable laminates.

Winding Technology

SML provides advanced winding solutions critical for high-quality coated films. The winding product range includes several series with distinct features:

  • Winder W1050: Turret type, supports inline slitting, max width 2650 mm, speed up to 350 m/min, equipped with cross-cutting and twisting knife devices.
  • Winder W1000: Turret type with flying knife, max width 2650 mm, speed up to 300 m/min, supports automatic core feeding and shaft handling.
  • Winder W1100: Turret type with guillotine cutting, max width 2650 mm, speed up to 350 m/min, supports multiple winding shafts and electrostatic core preparation.
  • Winder W1200: Extra-wide turret winder, max width 4450 mm, speed up to 350 m/min, flying knife cutting, supports shaftless operation and multiple winding shafts.
  • Winder W2000: Horizontal sliding winder, max width 2950 mm, speed up to 600 m/min, equipped with guillotine cutting and robotic bobbin handling.

All winders feature 15" touch screens and modem connections for user-friendly operation and remote support.

SMILE Control System

The SMILE control system integrates all process parameters into a centralized touch-screen interface, enabling operators to monitor and adjust individual drives and production settings. Key advantages include:

  • Centralized operation with history, trends, error, and help messages
  • Online data link to gravimetric dosing systems
  • Automatic line speed adjustment functions
  • Industrial Ethernet Powerlink for robust communication
  • Remote access capability for rapid service support

Laminator unit Especially in technical applications like laminates for the building industry (roofing material, scaffold sheeting, landfill protection) or tarpaulins for trucks or tents, the tendency goes to wider machines. Since basic materials like woven fabrics, heavy nonwovens or enforcement grids do not allow processing speeds as high as those used for papers, films or aluminum, the output can be increased by running wider products, and also some final applications demand a width of 4.5 meters or more. In this case, expensive welding processes and additional sources of troubles can be avoided...

Combined cast film / lamination line combined cast film /coating lines Regarding the machine components it is evident that one can find many synergies between cast film, calendering and extrusion coating. But also in process technology, especially for highly sophisticated barrier structures, the cast film or calendering process can be combined with an additional step of inline extrusion coating. The most important advantage of this process is the waste management, because the non-contaminated edge trims can be refed into the cast film or calendering process before lamination with another component....
