Abstract
A fabric manufacturing device having a drive to rotate a coiling mandrel (the so-called weaving blade), which, in order to avoid the difficulties of positioning the mandrel by means of motor, transmission, coupling and brake and in order to improve the productivity of the device, utiizes an electro-hydraulic torque amplifier as the mandrel drive, having an electrical step motor as a set-point value indicator, a switch valve as a servovalve and a hydromotor as an actual drive motor. A control device is provided which includes a positioning element for the step-wise positioning of the coiling mandrel in the rotational positions desired for certain points in time. In this manner, the invention automatically assures that the mandrel will precisely reach the desired rotational position and assures manufacturing of fabric with the highest possible rate of addition.
