PROCEDE ET DISPOSITIF POUR ANIMER UNE SURFACE D'UN MOUVEMENT DE VA-ET-VIENT DANS UN PLAN.

摘要

The invention concerns a device and process to causing a movable surface to reciprocate with an amplitude A2 in a plane. According to the present invention, two deformable parallelograms are arranged in a plane perpendicular to the plane of the movement to be produced. Each parallelogram has two sides parallel to the plane of the movement. One of these parallel sides is shared by both parallelograms and caused to reciprocate with an amplitude A1 = A2/2. The other parallel side of the first parallelogram is fixed while that of the second is caused to reciprocate with an amplitude A2. Application to strip perforation devices.
