MOL-254 (September, 2003) 1/2
MOL-254
● The new machine head specifically developed for belt-loop attaching
machines runs at a maximum sewing speed of 2,500rpm and is equipped
with a direct-drive system that improves start up performance and
shortens sewing time.
● The belt-loop feeding device is now provided with a halfway standby
capability for subsequent belt-loops, and its faster belt-loop supply action
shortens the time required for supplying belt-loops and helps speed up
the machine time to 1.2 seconds per belt-loop (with 28 stitches).
● Belt-loops are fed out by the conventional gear-roller feeding mechanism
and also drawn out by the new drawing mechanism on the clamp device.
Supported by these two mechanisms, the folding fork catches "curled" or
"creased" belt-loops every time and supplies them to the head.
● The machine preliminarily detects each splice in the belt-loops and
efficiently disposes them. This means that even when the machine
carries out the splice-disposal procedure, the belt-loop feeding device
can complete its belt-loop supply action and supply the next belt-loop
well before the machine starts to sew. As a result, the operator can
perform rhythmical and efficient sewing work with no delay in cycle time.
● The number of stitches to sew a belt-loop can be switched between; 28-,
36- and 42-stitches, and the bartacking size can be easily changed
through the operating panel. What's more, the user can create his/her
own original sewing patterns in addition to the standard ones using
JUKI's PGM-20 programming software developed for computer-controlled
sewing machines.
