This is the most commonly used wrinkle remover device. It mainly consists of bowed shaft, metal segments, abrasion resistant, rubber sleeve etc.
Vintex Engineering Works’ makes expander rollers (Bow rollers) having very wide range of dimensions and suitable for equally wide range of applications and web materials. They are supplied with mounting brackets , which could be either wall mounting or foot mounting.
The performance of rubber expander (Bow Rollers) depends upon Lead in –Lead out distance, Wrap angle , Position of bow (adjustable)3:1 lead in – lead out ratio is considered to be best . However lead out distance preferable should not to be more than 3 times of expander roller diameter.
The best results are achieved when bow roller is perpendicular to the web direction.
