Abstract
The invention relates to a method for applying forces and motions to warp threads (1, 1′) of a weaving machine with the following method steps: deflecting the warp threads (1, 1′) via a thread deflecting element (2) which is supported pivotably about a pivot axis (3); applying spring forces to the thread deflecting element (2) via more than three force application points (5) along a first line (6) which extends parallel to the pivot axis (3), wherein the spring forces are applied by at least one spring element (4); applying a prescribed positively constrained oscillating motion (38) onto the thread deflecting element (2) wherein this motion (38) is applied by a drive means (7) via a drive element (8), wherein the forces on the thread deflecting element (2) are supported partially via the thread deflecting element (2) on the at least one spring element (4) and partially via the drive element (8) on the drive means (7). The invention also relates to a corresponding apparatus.
