Abstract
At each work position of a textile machine having a plurality of work positions driven by a common drive unit (warper's creels, winder or spooling and spinning machines, or circular knitting machines, for example), an electronic monitor device is provided which is responsive to thread travel. An indicator device is associated with each travel monitor and comprises a storage element and an indicator connected thereto, for the permanent indication of a thread breakage. To prevent false indications of thread breakage when the machine is stopped, a control signal is generated when the machine's drive unit is operating. Each indicator device further includes an electronic switch responsive to the control signal to insure the storage unit can be set to indicate a thread breakage only during operation of the drive unit.
