Abstract (en)
[origin: EP0799919A1] Device for carrying out the programming of rotary dobbies for the operation of heald frames in weaving machines, of the type in which the heald frame operating levers (3) are actuated by connecting rods (2) each mounted on an eccentric ring (5) rotating with respect to the main shaft (1) of the dobby, which has moreover a disc (13) made to rotate by said shaft (1) and a selection lever (7) pivotably hinged on said eccentric ring (5) and designed to engage with said disc (13) via one of its end teeth (11), through the action of a spring (12). The device comprises operating means which are arranged alternately along or outside the trajectory at the end (8) opposite to the toothed end (11) of the selection lever (7) so as to cause or avoid the engagement thereof with the rotating disc (13). The action of said operating means is co-ordinated with the rotation of the main shaft. Said operating means comprise at least one electric linear stepper motor (15, 18, 19). <IMAGE>
