US Patent 6,581,646, granted 24 June 2003 to Andre Dewispelaere and assigned to N.V. Michel Van de Wiele, for a three-position shed-forming device used in jacquard machines. Two lifting blades with different lifting heights (h and 2h) move in phase, and a selection device lets a hook be carried by the upper blade, the lower blade, or neither. This gives upper, center and lower warp positions. A second embodiment pairs two such sets, moving in opposition, with a single pulley block element, for an open-shed machine. The document includes the abstract, claims, background discussion of prior patents (DE, EP), description of the figures and two sheets of mechanism drawings.
