TUCKER
Remove the presser foot and attach the tuck- er in its place. The width of the tuck is deter- mined by the scale of figures nearest the needle, which shows in eighths and six- teenths of an inch the distance of the edge of the fold from the line of stitching.
The crease or mark for the second and fol- lowing tucks is determined by the scale near- est the operator and this is set by the line in front of the needle hole in the presser foot. For blind tucks without spaces set both scales at the same figure; to make spaces between the tucks move the front scale far- ther to the left until the desired space is obtained.
Having adjusted the scales for tuck and space as desired, fold the material and crease by hand; pass the folded edge between the spring and spur near you, then between the two blades of the second scale, and back under the presser foot; draw to the right against the guide, lower the presser bar; see that the lever for the needle clamp to strike is in its backward position so as to form a crease for the next tuck, then proceed with the first tuck.
FIG. 34
For the second tuck fold carefully at the crease made by the spur and place the edge of the first tuck underneath and against the spur at the left. The spur will serve as a guide and will also make a distinct crease for the next tuck. Always place the last tuck against the spur to ensure perfect work.
When making the last tuck the lever upon which the needle clamp strikes while tucking should he raised to its highest point; while the lever is in this position no crease for a suc- ceeding tuck is made upon the goods.
