The tarpaulin welding machine (10) has a hot air device for heating the film material, a pressure roller (15), which is arranged behind the hot air device and is visible near the hot air device and in the movement direction of the welding machine, and a cam roller. One of the rollers is brought into a neutral position by releasing from a position in an axial direction, where the roller is decoupled from an axle (17) and is freely rotated against the axle in the neutral position. |
