Threading the two Top Threads Fig. 73 To thread the machine for pin-tucking with two top threads, proceed as for normal sewing. The thread spools are slipped on the double spool holder with the two spool pins 22 at the rear of the machine. The thread of the left reel is passed through the rear eyelet 8 on the top of the stand, hence to the eyelet 8 in front and through the rear thread tension disc which is separated from the front disc by an intermediate disc. Then pass the thread through the upper opening of the take-up lever 7, down behind the thread guide 32 on the stand and then into the needle holder eyelet 33 and finally through the left-hand needle eye. The second thread is threaded similarly, but passed through the front thread tensioner to the lower hole in the thread take-up lever 7, and through the right-hand needle eye. Both threads should be separate in the thread tensioner since better pin-tucks are obtained that way. Pin-lucking Fig. 74 A pin-tuck is formed by the bottom thread which pulls the two top threads together so that the fabric between the two needles is raised into a tuck. For pin-tucks with inserted cord, the insert is passed, from the ball slipped on a thread reel pin of the container, through the groove in the flap, through the hole in the throat plate between the two teeth rows of the feed dog, and passed away from operator below the pin-tucking foot. 94 Ornamental Stitch with Double Needle When using one pin-tucking needle and the standard zigzag foot, a parallel double ornamental stitch can be produced, the two threads being preferably of different colours. When using u double needle with 1/I2 and 1/i, inch gap, an additional zigzag motion can be performed. The needle deflection should only be so large that neither needle fouls the stitch bole either on the left or on the right. The zigzag lever 12 (Fig. 2) should therefore be moved slightly to the left of zero point. 1 495
