Abstract
A shedding device as provided for textile machines which includes oppositely movable lifting blades (41) and pulling elements (42) which are reciprocally movable between a lower shed position and an upper shed position and which are interconnected in pairs by a connecting member (1). The connecting member (1) is connected through a pulley block (2) to a heddle (7) and a retention device (12) is located at a lower shed position and between the pulling elements (42) to control the latter in accordance with the particular pattern program. The insertion device (12) has a wedge-shaped base (17) including a base edge (17a) directed toward the harness string (6). Magnetic pull areas (23, 24) are formed at inclined surfaces (20, 21) of the wedge-shape base (17) and through an associated air gap (A) progressive movement of the coupling portion (46) of each pulling element (42) is effected upon magnet energization or coupling/uncoupling operations at low forces and under relatively quiet operation.
