A sewing guide for a seam pattern sewing machine, provided with seam pattern selectors (14,15) and an electronic seam memory (16) for supplying stitch data to needle positioning and feeding mechanisms is constituted of a set of seam symbols (24,25) inserted on the front side of the machine to which seam selection buttons are associated and at least one switching means (15) related to the adjustment on e.g. some sort of cloth. Associated circuits in the electronics control the indicating means at the symbols, whereby some are indicated as suitable for the sort of cloth pointed out by the switching means. The seam selection is then effected by actuating the bottom of the selected symbol. The electronics comprises circuits for supplying ideal data controlling stitch length and stitch width for the selected cloth and seam, respectively. |
