ABSTRACT:
A programming system for preparing stitch instructions for the purpose of controlling the relative position between a needle and a workpiece by means of so varying the relative position between an index member and a record medium as the index member traces after the profile figured on the record medium. In this system a manual operating member is disposed for designating the direction and speed of variation of the relative position between the index member and the record medium. An exact tracing of a profile of complicated shape is made possible by designating the speed appropriate for the tracing of the profile through varying the angle of inclination of the manual member according to the shape of the profile. The programming operation for preparing the stitch instructions can be performed in this way exactly and easily.
