ABSTRACT:
The zone of movement of the reciprocating carriage of a flatbed knitting machine is guarded, to prevent injury to the operator, by a light barrier set up between each end of the machine and the carriage. Only the barrier on that side of the carriage towards which the carriage is moving at any given time is effective to trigger braking of the carriage and stopping of the machine if the barrier is penetrated. The carriage may carry a double-sided reflector with combined light emitter/receiver units positioned at each end of the machine.
