Ultrasonic splicing solutions for invisible and resistant splices

The solution for strong, invisible and reliable plain splices, without additive element such as glue, adhesive, needle and thread.

Customized solutions to fit your requirement:
• 2 technologies: butt-to-butt or overlap web splicing
• Integrated bench/module or separate equipment

Main advantages
• Quality and reliability improved
• Faster and more efficient assembly process
• Environmentally friendly

Roll Concept is the Exclusive European Distributor of Dover Flexo Electronics Inc.

Through the careful design and manufacture of automatic tension controllers, indicators, transducers and pneumatic brakes, DFE has successfully delivered solutions for customers’ industrial tension control needs since 1974.

DFE is the natural choice of OEMs, operators, process and controls engineers to outfit machinery with precise, easy-to-use tension control. DFE systems deliver improvements to material processing productivity and reliability, reducing waste and operating costs. These benefits enable payback on a new tension control system in as little as a few weeks.

Consistent quality, product reliability and superior technical support translate into low total cost of ownership for all of our customers.

Decoup+ offers different kind of devices to perform manual ultrasonic cutting and/or welding operations.

Our P and T devices are handheld solutions to perform small straight cutting, shape cutting or welding operations.

Our new Mini Press, is an independent workstation,really easy to use and which allows, depending on the tool, to perform press cutting, welding and/or punching operations on any fusible fabrics (textile, technical textile, nonwovens, plastic…). Thanks to its compact design, our new Mini Press can be easily installed on any workshop.

Our ultrasonic welding station, is an individual and ergonomic working station for "stitching" operatoins withour any additional material

Specification:

• Compact and flexible
• Versatile devices to perform cutting, welding and punching operations, with easy settings
• Mechanism very preciseand sturdy
• Rigidity and precision
• Easy to use and reproducibility: gap setting through fine pitch

As a specialist in continuous ultrasonic cutting and sealing, we will also design and manufacture different ultrasonic equipment, applicable at any stage of the textile production process:

• ultrasonic heads to be integrated on existing machines such as looms, stenters, inspection machines, slitter-rewinders
• ultrasonic splicing bench for on-line or off-line splicing operations

The Roll Concept idler rolls guide and transfer the web at different steps of the production run on your machines. Our technical rollers and winding cores are usually made from aluminum profiles called ALVEOTUBE®. These patented profiles have been designed to offer an ideal combination of low inertia, low weight and high resistance to flexion.

Our ALVEOTUBE®is the best compromise on the market between bending resistance and inertia and allows decreasing electrical power need and consumption during speed-up phases.

Specification:

• Specially engineered to improve process performance and increase line speed on web handling and converting industry, our lightweight precision rollers and cores ensure to our customers easy installation, easy handling and durability
• They keep a constant tension on the webs thanks to reduced friction and perfect rotation
• Their light weight and the unique alveolar structure enable to combine bending strength and resistance to corrosion, 
• Our range includes simple profile but also ready to run solutions: customized in different diameters and lengths with a choice of surface treatment, mountings and coatings

Your project study can bring us to recommand other material than aluminium. We can also advise you to use composite materials for extreme applications, or steel for high resistance needs.

From compact slitter able to convert secondary rolls into narrow tapes or tubes up to 6mm wide, to XXL slitter rewinder up to 3.4 m.

Specification:

Based on a modular concept our slitter-rewinders include:

• separated or integrated unwinding station,
• double unwinder for tubing application,
• easy loading/unloading systems,
• slitting stations with 2 or 3 cutting systems depending on the machine type (hot, crush, shear, combined, ultrasonic, razor blades),
• Quick slitting width adjustment systems,
• Scrap extractors,
• Duplex centre driven or centre surface driven rewinds,
• Simplex centre winder, lay-on arm, cantilevered rewinding shafts, swiveling shafts…
