US Patent 3,944,134 (granted March 16, 1976) to Pierre Frappe of Lyon, assigned to Verdol S.A., describes a machine for punching the cards or paper bands that control jacquards and dobbies. Horizontal punches are driven through presser rods selected by vertical retaining rods, which are held in place by banks of U-shaped electromagnets receiving signals from a photo-electric reader or other source. The scan includes a 2001 USPTO web printout of the full text, the printed patent with claims, and four sheets of drawings (Figs. 1-6).
