Latest Patents

One of Stark's latest patents is focused on "Clearing mispicks in rapier looms." This innovation addresses weft yarn faults encountered during the operation of rapier looms by correlating the detection of faults to the angular position of the loom's rotating main shaft. The loom features a shed with a giver side and a taker side, equipped with a giver rapier and a taker rapier. Position signals are stored in an electronic device for weft yarn faults that may occur at predetermined angular positions during operation. The weft yarn is monitored, and a signal is generated upon detecting a faulty yarn. This signal is then compared with position signals in a logic circuit to determine the nature of the fault. Once identified, the faulty weft yarn is removed, allowing weaving to continue seamlessly.

Another significant patent by Stark is the "Yarn selector unit for a weft feeder." This invention involves a yarn selector unit that has multiple feeders, each associated with a specific weft yarn. Each feeder is driven by a tongue that can be selectively moved via a lever and slide. The tongue's position is clearly defined, ensuring that misactuation of the yarn selector unit does not occur. This innovation enhances the precision and reliability of yarn selection in weaving operations.
