Spiral Winder
Overview
The spiral winder strips a paper web from the unreeling and forms an endless spirally wound tube. According to requirement different internal layers are wound onto the core, with or without coating and/or sealing in order to obtain high impermeability of the tube.
The various executions of the spiral winders depend upon performance and format range.
