Computer-controlled, Dry-head, Lockstitch Sleeve Setting Machine
with Multi-programming Device
DP-2100
● The DP-2100 is able to easily carry out sleeve-sewing processes,
which are regarded as the most difficult, promising a higher
finifhed-seam quality.
● Thanks to JUKI's unique right-and-left independent drive system
of the top feed belt, right and left feed amounts can be
adjusted separately. This prevents the material from slipping out
of position, thereby sewing sleeves with a consistent seam
allowance.
● The machine comes provided with a mechanism for moving the
belt feed and intermediate presser up and down alternately,
enabling it to eliminate tucks produced at the sleep cap as well
as irregular puckering produced in the neighborhood of the
sleeve cap.
● By introducing the belt feed, the machine reduces scratches to
the material made by the feed.
● The introduction of active-tension enables the separate setting
of suitable thread tensions for sewing sleeves on a portion-by-
portion basis. This prevents an inadequate thread tension at a
portion where the shirring amount is large or an excessive
thread tension at a portion where the shirring amount is small.
In addition, specified tension settings can be stored in the
memory on a pattern-by-pattern basis and can be reproduced
with ease.
