Abstract

A shed-forming device, in particular an electronically controlled jacquard machine, with a number of combinations of at least two selection systems (3, 6 7), (5, 8, 9) respectively with selection elements provided one above the other. Each selection system comprises two hooks (6), (7), (8), (9) working together and that can be moved up and down by lifting device (13), (14) which can be selected by a selection element (3), (5). Hooks of different selection systems of a combination can be moved up and down, allowing for the use of simple selection elements. Two selection systems are provided per combination. This enables the number of selection systems with similar machine dimensions to be almost doubled in relation to the known devices. The hooks of selection systems of a same combination are movable by one and the same pair of lifting device (13), (14) and each lifting device (13), (14) has at least two parts for being able to engage respective hooks, well separated from one another, of different selection systems of the same combination.
