(6) Adjustment of the looper motion paths
1. Looper momentum in the front-rear direction
(1) The standard position of the front looper
is decided under the condition that the tip of the needle
touches the rear of the front looper
at 1/4" from the bottom surface when the pulley is rotated
counterclockwise and the front looper
is moved from right to left after mounting the front looper
in a
standard manner.
(2) For the middle and rear loopers (
and
), the standard position for each is decided under the same
condition as the front looper, i.e. the tips of the needles (
and
) touch the rear of the loopers at 1/4" from
the bottom surfaces, respectively.
(Caution) If the material has a thick unevenness during sewing, contact areas between the needle tips
and the rear surfaces of the loopers (
and
) may become smaller. (to prevent needle tip
breakage)
