From simple to automated<\/h2>\n\n\n\n

We build machines for the controlled unwinding of a wide variety of materials. From “very simple” to “highly automated”: We have the right concepts for every requirement.<\/p>\n\n\n\n

Applications range from the fabrication of web-shaped materials and applications in converting processes to laminating and coating applications in inline systems or offline processes.<\/p>\n\n\n\n

We will be pleased to support you with competent advice on the right selection for your application.<\/p>\n<\/div>\n\n\n\n

Different roll chuckings<\/h2>\n\n\n\n

Depending on the requirements, material roll chuckings with different winding shafts or shaftless material roll clamping are available.<\/p>\n<\/div>\n\n\n\n

Braked or driven, controlled or uncontrolled<\/h2>\n\n\n\n

We can provide unwinders with brakes or drives and with different web control concepts, depending on the material types, roll weights and line speed. What’s more, there are corresponding machine concepts for both winding directions.<\/p>\n<\/div>\n<\/div>\n\n\n\n

Manual web splicing or automatic splice<\/h2>\n\n\n\n

The machines can be designed with manual web splicing, such as splice tables, with press and heating presses for web splicing, with ultrasonic welding devices as well as with typical adhesive splices. Depending on the type and concept, the web splicing is carried out during standstill or “on the fly” while the web is running.<\/p>\n\n\n\n

We also offer splice concepts for overlap web splices and for “butt to butt” splices. With automatic overlap splices, the automatic unwinders achieve only the smallest overlap lengths even at high speeds – also with “splice on the fly”.<\/p>\n\n\n\n

Automation options<\/h2>\n\n\n\n

In addition to manual placement concepts, our range also includes many automation options. These include roll loading trolleys, pick-up winding stations or crane-guided systems.<\/p>\n<\/div>\n<\/div>\n\n\n\n
