Ruti-te Strake B.v.

A shuttleless weaving machine has a shedding mechanism, a weft conveyor for launching a weft thread through a weaving shed provided by the shedding mechanism, and a plural weft preparation device for delivering weft threads according to a repeating pattern to the weft conveyor. There is a disconnectable coupling between the plural weft preparation device and the shedding mechanism. An angular position comparator includes a part coupled to the shedding mechanism and a part coupled to the plural weft preparation device, said parts assuming a marked angular position relative to each other during normal operation while rotating through 1/(an) revolution per weaving cycle (a=number of wefts after which the weft pattern is repeated, and n=number of marked angular positions). Means are provided for detecting such marked relative angular position of the two parts, which means operate, while such position is not detected, to disconnect said coupling. An auxiliary motor is connected to the plural weft preparation device, for driving said device and the part of the comparator coupled thereto to bring said part to a marked angular position relative to said other part.
