Abstract
In a safety device, in particular for flat-bed knitting machines, with which, by means of a shutoff device, stoppage of the carriages associated with a drive apparatus of the machines in the event of a change in the power of the carriages as compared with applicable normal operation resulting from disruptions in removal of the goods, loop formation and yarn insertion, excessively high loop tightness specification or the like, is effected. A measuring device is provided for detecting a torque-proportional variable of the drive mechanism. Actual values of the torque-proportional variable are deliverable to a central processing unit and an adjustable comparator device, and the comparator device is provided by the central processing unit, with threshold values for this torque-proportional variable, serving as processed actual value for the torque-proportional variable. Finally, by means of the comparator device, the shutoff device is triggerable as soon as the applicable threshold value is exceeded. Thus in a safety device of this kind, the varying conditions in individual flat-bed knitting machines of the same of different types and in the various operating programs can be taken into account, because the safety device can be made adequately sensitive for each case.
