Abstract
A suction device for a double-point coating system is used to remove excess powder (3') from a double-coated fabric web (1). The suction device has a powder-suction element (4) to remove excess powder, a fabric-web-suction unit to align the fabric web and at least one beater roller (8, 9) to loosen excess powder. The fabric web suction unit has at least one suction roller (5, 6, 7) that can rotate to convey the fabric web (1) and support it. That way, the fabric webs can be transported tension-free, which largely prevents adhesion of individual dots of paste and clogging of the textile.
