Not only the imitation Germany loom with two beating up but also the imitation Japanese loom with one beating up, The correct cloth take-up time shall be the time of beat-up of weft wire because the cloth tension is at the minimum value at the beat-up of weft wire time which is easy to take up the cloth and reduce the workload of the cloth take-up mechanism. If the cloth take-up time is before and after the beat-up of weft wire time, the workload of the cloth take-up mechanism would be increased; at the same time, the tension of the cloth surface is suddenly increased during the cloth take-up action which is easy to cause the plain weaving cloth fork and break.
