US Patent 3,090,550 by Gabriel Servillat, assigned to Société des Mécaniques Verdol, Lyon, describes a machine for preparing Jacquard pattern cards, specifically continuous paper bands for Verdol Jacquards with 1,344 hooks. A carriage with an obliquely arranged row of electromagnets moves continuously past rows of retaining members that control the feeler needles of the punching device. The electromagnets are driven by photo-electric reading of a squared pattern drawing or by a perforated tape memory, through electronic "and" gate circuits. The document includes two sheets of drawings, the specification, nine claims and cited references.
