<p>The towel dispenser winds the towel up on a roller in the housing after it has been drawn down from the supply roller and moved over a conveyor roller. The gear wheel of the latter interacts with a spring. The intake roller of the feed-in mechanism can be coupled with, and uncoupled from, the conveyor roller by a coupling which can be switched on directly or indirectly by the end of the towel. The coupling can be closed by rotating the conveyor roller as the towel is drawn down and can be released by a short backward rotation after the towel has been drawn down through the reaction of the spring.</p> |
