● A small-diameter cyilinder bed has been introduced. As a result, the
operator can easily handle the sleeve cuffs of children’s wear,
the diameters of which are very small. The cylinder-bed allows the
operator to help feed a tubular material being sewn along the bed.
This helps reduce the operator’s fatique.
● The machines in the MOC-3900 series in corporate high-precision
components, are light in weight, and can sew pieces of material
without applying heavy pressure on them. These features enable the
machines to smoothly feed soft and delicate materials as well as perform
consistent sewing, while preventing the material from flopping and the
presser foot from jumping even when running at high speed.

● The machine comes with the top-feed dog that moves along an ideal
locus. The feed dog securely catches the material and allows the
multi-layer portion of a material to be fed under it with consistency.
In addition, it helps finish uniform seams while preventing the presser
foot from jumping and smoothly feeds the material without fail.
Compact-shape of the cylinder effectively prevents the material from
being fed unevenly and from twisting in various kinds of sewing of
tubular materials, e.g., joining sleeve cuffs of which diameter is small
and blind hemming long materials.
● The machine achieves the highest sewing speed among cylinder-bed,
variable top-feed overlock machines. It demonstrates its sewing
capabilities especially when blind hemming long materials.
In addition, it is not necessary to reduce the sewing speed even if the
material thickness changes at joints or the like.
