Operators Manual
ALS 221
Dispensing is only possible when the handle (015) is in the closed position. Via the deviator
roller (016) the backing paper is guided to the rewind mandrel (017). The cone between the 4
pins can be pulled out to allow the reward backing paper to be removed.
Except for the drive roller (001) and the material brush (006) the labeller has no wearing parts.
The operator panel (019) is described in the next chapter.
A threading diagram is affixed to the front of the machine, which shows how the label material
should be threaded through the machine.
Screw (014) secures the position of the pressure roller (013) in a lateral direction. In order to
achieve a reliable run of the label web position, adjust the roller to the centre of the label web.
