WEAVING MACHINE WITH A SYNCHRONOUSLY OR INDEPENDENTLY OPERABLE MECHANICAL DOBBY ABSTRACT A weaving installation includes a weaving machine and a dobby which can be driven by the weaving machine. In order for the weaving machine to drive the dobby, the weaving machine may be provided with a pulse generator for the transmission of pulses to a control unit which, in turn, regulates a motor coupled to the dobby. Alternatively, the camshaft of the weaving machine may be provided with an extension which is directly connected to the dobby. The dobby may also be driven independently of the weaving machine. In the case where the weaving machine has a pulse generator which controls a motor coupled to the dobby, this is accomplished in that the motor is operable even in the absence of pulses from the pulse generator. In the case where the camshaft of the weaving machine has an extension which is directly connected to the dobby, the dobby can be driven independently by a planetary gear on the extension. The planetary gear has a housing which is coupled, and is rotatable relative to, a motor and is also connected to the dobby thereby allowing the latter to be driven by the motor independently of the weaving machine. A brake enables the housing to be fixed against movement relative to the associated motor so that the dobby can be driven by the weaving machine.
