964, 121. Jacquard harness boards. SOC. DES MECANIQUES VERDOL. April 17, 1962 [Feb. 19, 1962], No. 14726/62. Heading D1E. A harness board is made by assembling two layers of hard steel rods 3, 4 between spacing pins 2 on a Fig. 1. The projecting ends of the rods are then embedded in synthetic resin by immersing them in a metal channel containing liquid resin; when the resin has polymerized, the channel may be removed or may be left in place to form part of the harness board. |
