4-146 DVP-MC operating manual
Additionally, when rotary cut function is started or broken off, the cam curves used are different.
The entry curve
It is the rotary cut curve when rotary cut function is started
The curve is the rotary cut function entry curve. When the rotary cut function is started up, the rotary cut axis
will follow the feed axis to rotate according to the curve. The entry position is based on the rotary cut axis. For
the single knife, the cutting position is directly below the rotary cut roller if the entry position is over the rotary
cut roller in the following figure. Before the rotary cut function is started up, the knife must be turned to the
upper of the rotary roller. Otherwise, the cutting may happen in the adjustment area.
When the rotary roller is mounted with multiple knives, the distance between knives should be the same and
the cutting position is at the center of the knife distance. See the two-knife figure below.
