product information

Automatic transfer unwinder UR Precision U – How does it work? The automatic transfer unwind system ensures nonstop feeding of web materials to printing and converting machinery. Non-stop production is achieved by automatically butt splicing of the leading roll edge of the new roll to the trailing end of the running roll at full process speed. The material rolls are loaded into the machine with an integrated lift and load system.

The servo-driven festoon continuously feeds material to the process during the splice cycle and is complemented by an integrated isolation dancer to isolate the unwinding process from the press line. This state of the art system provides a fully integrated package that maintains non-stop production with no impact to the printing or converting process.

Scissor-cut buttsplice unit

All servo drive concept

Visualisation

Scissor cut buttsplice unit to create a high-precision butt splice at a 15 degree angle with tape on both sides of the material.

Center drives as well as festoon linear drives by means of AC servo gear motors, CoDeSys direct drive programming, touchscreen visualization plus Ethernet Bus communication.

Simple, intuitive operator interface with touch screen operation, displaying all current roll parameters. Digital readouts of fault indications for easy troubleshooting, plus extended menu navigation to 2nd and ntenance and programming screens.

Automatic transfer rewinder UR Precision R – How does it work? The automatic transfer rewinder ensures nonstop winding of web materials coming from printing and converting machinery. Non-stop production is achieved by automatically severing the trailing end of the winding web and automatically attaching the leading edge to a prepared core. A unique “flying scissors” mechanism ensures a smooth straight cut-off no matter what material is being processed.

The fully wound rolls are pneumatically loaded onto a movable roll lifting cart. Floor contact and contamination of the finished rolls is eliminated. An optional web guide can be included to provide perfect edge alignment of the roll. An operator selectable lay-on-roller plus a fully adjustable taper tension control provides perfect winding quality.

Scissor-cut transfer unit

All servo drive concept

Visualisation/Job-Save function

Transfer unit based on “flying scissor”-principle, for easy cutting of rigid materials and delicate film substrates; web transportation on to prepared core using servo driven linear guide.

Roll center drives, 180 degree rotation turret, scissor-cut transfer unit plus web shifting device by means of AC servo gear motors. CoDeSys direct drive programming, touch screen visualization as well as Ethernet Bus communication are completing the drive package.

Simple, intuitive operator interface with touch screen operation. Individual winding paramaters can be stored and recalled to reduce labor and material usage.

Automatic Matrix transfer rewinding system UR Precision M – How does it work? The automatic matrix transfer rewind system ensures nonstop winding of self-adhesive matrix produced by a combined printing and die cutting process. The sticky matrix is wound to a self-made additive core. When the maximum roll diameter has been reached a bump and cut mechanism automatically transfers the leading edge to the self-made core.

The full roll is then pneumatically pushed into a safety stop position to allow for an ergonomic lift-off by the operator. A lay on-roller, non-stick coated rollers and a speed fine control potentiometers guarantee a material independent stripping- and winding quality.
