ABSTRACT:
A knitting machine section block is fitted with one or more strain gauge means, preferably on a backup plate for a needle influencing cam, so that during operation of the machine and without any adverse influence upon the output of the knitting machine, signals may be generated in response to the forces transmitted by the interaction of the knitting needles with the needle influencing cam. By analyzing the signals generated by the strain gauge means, as for instance, by the use of an oscilloscope, patterns representing the actual conditions may be compared with those of usual operation to identify specific part defects or specific abnormal conditions of operation.
