The direct singeing system forms the technological basis of all osthoff-senge singeing machine.

The direct, very intensive flame, the short contact time between flame and free-guided fabric, the ignition flame temperature necessary for the vaporization of polyester and the various singeing positions represent the decisive advantages of the osthoff-senge singeing system.

Before Singeing

After Singeing

Onto free-guided fabric
Flame meets right-angle onto dense woven fabric freely guided between 2 rollers, recommended for natural fibres and blends weighing more than 125g/m²

Singeing onto free-guided fabric

Onto water cooled roller
Flame meets right-angle onto the fabric bended over a water cooled roller. Recommended for fabrics of temperature sensitive fibres, those of open-weave, blended ones weighing less than 125g/m²

Singeing onto a cooled roller

Tangential singeing
Flame passes tangentially over the fabric bended over a water cooled roller recommendable for fabrics which cannot tolerate direct exposure to flame and for repair of filamentation

Tangential singeing

Flame shearing
Flame passes tangentially over the fabric bended over a singeing sword, with minimized contact time, singeing effect on fibre tip only
