Threadlns Ih* two Top Thread* Pig. 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, hut
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.

Oi i i a m c H t i t l Siiteli it’ith Donile Needle
When using one pin-tucking needle and the standard zigzag foot, a parallel double
oinaiuentai stitch can be produced, the two threads being preferably of different colours.
When using a doublé needle with Vi: and ‘Is inch gap, an additional zigzag motion can
be perfumied. The needle deflection should only he so large that neither needle fouls
tlie stitch hole either on the left or on the right. The zigzag lever 12 (Fig. 2) should
therefore he moved slightly to the left of zero point.
