Class Information
Number: 83/58
Name: Cutting > With randomly actuated stopping means
Description: Device provided with means capable of bringing any or all of the moving parts of the device to a halt, such means acting to accomplish its halting effect in response to a signal or impulse which cannot be predicted to occur during any particular one of a number of recurring cycles of operation (either of the machine as a whole, of the tool, or of any part of the machine which has a cyclic law of operation).
