Paper perforating machine 207-20

The drilling machines of the 207 series are characterised by extensive basic equipment and user-friendly features. It is equipped with a tangential chain drive, which allows the drilling heads to be easily adjusted and replaced. Due to the large adjustment range of the drilling spindles, a considerable insertion depth of 300 mm and also due to the number of drilling heads - up to nine are possible - the application range of the 207 series is also considerably larger. The drilling heads can be plugged into the machine through exchangeable indexing bars for all current standard hole patterns. This simplifies the changeover process and prevents errors when adjusting the centre distances.
