Synchronized drive system for a leno selvedge

摘要

The mechanical loom includes a drive unit for a shaft of a device from a leno selvedge and is synchronized with the frames of a mechanical loom. The drive unit comprises a first electromotor and a second electromotor. The drive shaft (111) is actrated by the first electromotor (110) (driving motor) and is electrically coupled with the second electromotor (120) driven by the driven shaft (121) of the mechanical loom, by at least two phases of alternating current waveforms carried by two or three electric transmission wires coupling the first and second electromotors together.
