Drying and Thermobonding Technology

AUTEFA Solutions specialises in the production of single and double belt dryers and thermobonding ovens for all nonwovens processes. The key strength of the AUTEFA Solutions belt dryers, uniform airflow and temperature distribution, the maintenance or even creation of high loft on the one but highest density as well as utmost energy efficiency on the other hand recommend the Autefa Solutions thermobonding and drying oven for industries that may use other systems today.

The AUTEFA Solutions circulation air oven is made to thermobond, heatset and also dry nonwovens.

As a thermobonding oven it allows processing of natural, recycling, glass and other mineral fibers to synthetic fibers. As a binder one can use bicomponent or polypropylene fibers but thermoplastic or duroplastic binder powders can be used as well. Heatsetting needle punched nonwovens is another field of application. The AUTEFA Solutions Oven can work in line with carding lines, carding and crosslapped lines, airlay, wetlaid and airlaid (pulp) lines.

The right nozzle for every process

Thermobonding, heatsetting and drying – all processes require different approaches. The HiPerTherm comprises a unique nozzle change system that allows to equip the base machine with the right airflow system for various processes. The multitude of airflow choices combined with the process knowhow of our specialists allows flexible layout of each HiPerTherm to process needs.
