Abstract:

We present herein a genuinely new concept for a rotary mechanism for pneumatic looms, which forms the shed and beating-up the weft, together with an electromagnetic device to drive the guide needle bar. The mechanism and device which we designed and constructed were tested using a model loom. The tests carried out indicated that the use of these machine parts increases the efficiency of looms which manufacture nets with leno weaves, significantly reduces noise generation by the loom, allows for weft inserting with the use of an air stream, and improves the energy balance of the loom.
