An apparatus for controlling the carriage drive motor of a flat-bed knitting machine is provided with a device used for activating, accelerating and turning off the carriage drive motor. The apparatus has at least one manually operable handlebar, essentially extending along a longitudinal section of the machine. The handlebar is mechanically connected to the device which causes the activation, acceleration or turning off of the motor. In order to make possible by means of the already present manually operable handlebar not only the activation and turning off of the carriage movement, but at the same time a continuous adjustment of the speed of the drive motor or of the carriage along the needle bed from a very slow creep rate to working speed, it has been provided that the device causing the activation, acceleration or turning off of the motor have an electrical transducer which can be continuously adjusted by means of the handlebar and that the output of the transducer is a measure for the relative change to the present working speed.

Apparatus for controlling the carriage drive motor of a flat bed

The device for monitoring the knitwear (16') of a flatbed knitting machine for falling-off exhibits several support bodies (18) having in each case a feeling lever (17) which rests against the knitwear (16') and which is coupled to a switching arm (25). The switching arm (25) is constructed as a contactless contactor and is moved during an adjusting movement of the feeling lever (17), which is triggered when knitwear (16') has fallen off, through the contact range of an electric switching device, for example a light barrier or an ultrasonic barrier or through a magnetic field area into an ineffective end position so that a control signal can be triggered only during the adjusting movement of the switching arm (25) between its end positions.
