2 Hemmer (Hem with a width of approximately V»") Attach the hemmer in place of the ordinary presser foot, raising the presser foot bar for the purpose. Fold the edge of the material over to the desired hem width and guide the fabric into the spiral-type guide tongue of the raised hemmer as far as the needle, then lower the hemmer. When sewing, lightly guide the prefolded edge (see fig. 29). If too much fabric enters the hemmer, the seam will become bulgy and uneven; if too little, the hem will not be folded in sufficiently and does not close the seam in the correct way. Gathering foot (Only supplied against extra charRc) Fin. 30 28 insert gathering foot. Adjust machine upon plain stitch sewing. Put the material to he gathered under the gathering foot, that is to say nol into the transverse slot. Lower the gathering foot by means of the presser foot lever and insert the piece of material, which must remain quite flat, into the transverse slot of the gathering foot as far as it will go. To increase the amount of gathering on the bottom material, hold the top material back. The more it is held back, the greater the fullnes of gathering, and vice-versa. If only ony layer of material has to be gathered, place the material beneath the gathering foot onto the feed dog, and the length of stitches will regulate the fullness of the gathering. A longer stitch will increase the fullness, whereas a shorter one will decrease it. Edger Adjust machine upon plain stitch sewing anti insert edger instead of regular presser foot. The edger with its stitch hole placed farthest to the right of foot is specially suited for edge stitching. For this purpose the edge stitcher is used without the quilting guide. The edger with the quilting guide is generally used for quilting works (see fig. 31), the distance of the guide from the needle determining the width between the rows of stitches. Adjust adequately and when sewing guide the material in such a way that the quilting guide runs always within the precedent scam. In such a way all the seams - the cross seams included - are quite parallel one against another. K!k. 31 29 THE ZIPPER FOOT (specially designed for inserting zippers; available only against extra chargc) 30 When inserting zippers be sure that for the stitching nf the left side of Ihe zipper the needle position to the right must be used (see fig. 34). Thus knob 17 should be set to the right (see fig. 21. The stitching of the left side of the zipper must be done with needle position to the left (sec fig. 33). Zipper Presser foot base Layer of material Layer of material Needle insertion to the right Presser foot, base Needle insertion to the left Presser foot base Kfe. 33 Fiz. Presser foot base Zipper 31 Zigzag Zigzag Sewing, with service by hand Adjustment of Stitch Width At the right-hand top of the body of the machine the adjustment knob 18 (see fig. 2) which serves to regulate the stitch width will be found. When turning I his zigzag adjustment knob 18 the width of the stitches will be set. The pointer on the knob 18 enables you to read on the stitch width scale the actual width of the seam. For plain stitches the Ffcc. 36 n b c I i I 32 pointer of the knob must indicate number zero on the stale. Thus a plain stitch will result. When turning the adjustement knob 18 to the right (in clockwise direction), the pointer will move from number zero to number four. The higher the number, the wider the stitches. The adjustment knob 18 can be regulated whilst sewing, but when you are not operating the machine, it can be set only when the needle is raised above the layer of material. Centre - right - left position Above the zigzag adjusting knob 18 a lever 17 is provided. This lever can also be adjusted when sewing, but when the machine is at a standstill, it can be set only when the needle is raised above the layer of material. By placing said grip upwards, i.e. when the pointer is in an upright position, the needle throw will be uniform to both sides, proceeding from the centre, to the left and to the right (see fig. 36 a, centre position). By turning the grip 17 in such a manner that the arrow points to the right, the needle will now throw from right to left when making zigzag stitches, the a) Centre position Needle throw from centre evenly to both a id cm 10 Right position Needle throw starting from a straight line at right edge of seam e) T.ejt position Needle throw starting from a straight line at left edge of seam piercing «if the needle being in a straight line only at the right edge of the zigzag stitch ( fig..'!<> b. right position i. On the other hand, if the arrow points to the left, the piercing of the needle will be in a straight line only at the Irfl edge of the zigzag stitch t fig. 38c, left position). Most zigzag sewing is done with the zigzag stitch adjusted in centre position, while the sewing machine is generally set to the left position when making buttonholes, s...
