Polyband expander

MENZEL polyband expanders combine the advantages of many other spreading devices. As with the slat spreader, the fabric is stretched over its entire width in a way that is gentle on the material. At the same time, the spreading effect can be infinitely adjusted manually during the run, as with the spreader roller. Due to these features, our cord spreader is particularly suitable for use with sensitive materials, such as very thin films, but also in the paper, nonwoven and textile industries. With our years of experience in fabric handling as well as winding and unwinding, we can easily accommodate your different requirements and loads.

The core of the polyband expander is an aluminum body with 24 or 30 longitudinal grooves arranged evenly around the circumference. Highly elastic round cords are guided in these profile grooves. The stretching behavior of this special round cord ensures crease-free, gentle and uniform spreading over the entire fabric width. Special cord types allow for temperature ranges of up to 170 °C.

Depending on your type of fabric, you can adjust the web speed and the wrap angle. The maximum speed is 350 - 600 m/min, depending on the diameter, and the wrapping angle can be set between 30° - 160°. In addition, you can also adjust the width effect continuously between 0 - 100 mm during operation. For very low web tensions and sensitive goods, a driven version is also available on request.

As we offer a wide range of fastening variants, it is also possible to install the cord holder at a later date. In addition, the maintenance of the cord holders is uncomplicated and spare parts as well as replacement cords can be easily exchanged on one's own.

We will be happy to advise you personally to find the right polyband expander for you!
