Abstract:
1. A drive mechanism for a weaving machine and shed forming machine with means for compensating r.p.m. fluctuations of the drive of the weaving and shed forming machine, (a) wherein the weaving machine includes an electric motor drive which is connected directly or through intermediate gear means with its main drive shaft, (b) wherein the shed forming machine includes an electric motor drive which is connected directly or through intermediate gear means with its drive shaft, (c) wherein at least the weaving machine includes means for braking the main drive shaft; (d) wherein a control unit is connected in a signal transmitting manner with the weaving- and the shed forming machine, (e) wherein the control unit includes closed loop control means for operating respectively one of said drives in dependency of the other of said drives, characterized in that said means for compensating comprise at least one partial flywheel mass ( 1 . 5 , 1 . 11 ; 5 . 4 , 5 . 14 ; 6 . 5 , 6 . 16 , 8 . 10 , 8 . 18 ) which becomes effective on the main drive shaft ( 1 . 8 ; 5 . 7 , 6 . 7 , 8 . 1 ) of the weaving machine and at least one partial flywheel mass ( 2 . 5 ; 5 . 14 ; 6 . 5 ; 6 . 16 ; 8 . 10 , 8 . 18 ) which becomes effective on the drive shaft ( 2 . 8 ; 5 . 17 ; 6 . 19 ; 8 . 15 ) of the shed forming machine or that gear means are provided which permit the mass inertia moment of at least one flywheel mass that is entrained for rotation with an electric motor drive ( 5 , 5 A; 6 , 6 A; 8 , 8 A, 8 B) of the main drive shaft of the weaving machine, to become effective on the drive shaft ( 5 . 17 ; 6 . 19 , 8 . 15 ) of the shed forming machine, that the drive of the weaving machine comprises a plurality of electric motor partial drives ( that the drive of the shed forming machine is at least one of the electric motor partial drives that the means for braking are preferably first brake means which are integrated into the partial drives, which bring the weaving machine to a standstill, that further second brake means ( that third brake means ( that all electric motor partial drives
