Juki PFAFF
Juki Corporation has been
leading in sewing machine
technology for over 75
years. Germany-based PFAFF,
known for its sewing
automation machines, also
offers a gamut of welding
machines. PFAFF 8310-144
is a new ultrasonic welding
machine which comes with
a patented double wheel
solution. The welding and
cutting wheels can be set
separately. Parameters
such as amplitude of the
sonotrode, speed of the
anvil, and pressure of the
anvil can be preset using
touch screen controls for
each type of fabric whilst
layer detection devices
change these parameters
automatically to cater to
different thicknesses and
types of materials.
Juki’s LWU-3015 is
an ultrasonic welding
machine which is a perfect
alternative of sewing in
non-woven fabric. The
ultrasonic welding results
in seamless finishing that
facilitates comfort and high
stretchiness. The machine
uses a specialised horn to
fuse two bits of material
together. The horn vibrates
and generates ultrasonic
energy which causes heat
at the points of contact with
the material and results in
polymerization. The shape
of the horn is such that
the residual material is cut
away as it passes beside
the horn. The feed speed
of LWU-3015 is 0-8.0m/min
(minimum 0.1m/min).
8310 offers a welding
speed of 0.5 to 20 metres
per minute, a seam width
of 0.5 to 10 mm, 35 KHz
of operating frequency of
sonotrode, and welding of
materials thicker than 50
microns.

Sonobond
Ultrasonics Nucleus
Ultrasonics Schips AG
Automation
Sonobond Ultrasonics is a
leading player in ultrasonic
technology for non-woven
and woven synthetic
materials. The Sonobond
SeamMaster High
Profile Ultrasonic Sewing
Machine can seal, sew and
trim synthetic fabrics without
the use of thread or glue.
SeamMaster is available as
modular unit which can be
integrated into production
lines just like basic sewing
machines while providing
a speed of 60 feet per
minute, which is nearly 4
times faster than a sewing
machine and 10 times faster
than adhesive methods. Founded in 1976 and
based in Duesseldorf
(Germany), Nucleus has
continued to develop
the ultrasonic welding
technology further for
application on technical
textiles, non-wovens
and films. The Nucleus
Rotosonic V4E is a multi-
purpose machine in four
variants for flat fabrics,
3D-parts, small parts and
preforms. The flatbed
machines can be equipped
with pillars and downward
arms simply by plug & play.
Also, the wheels can easily
be changed.  Based in Tuebach
(Switzerland), Schips
has over 50 years of
experience in sewing
automation in the apparel
and underwear sector.
It specialises in the
manufacture of automatic
workstations for the
garments industry and has
further added ultrasonic
technology to its portfolio.
The company offers a high
degree of consulting and
very specialised machine
configurations depending
on the need of the
customer. Martin Schips,
CEO of the company, talks
of ‘plug & play’ solutions
including optimised details
for the welding process.
Seams welded on the
machine fulfil the OSHA
requirements for barrier
seams, which state that
any seam in a garment
to be used by a medical
professional must be
capable of barricading liquid
from entering the garment.
