New extrusion film line
technology to AAPPI
Wayne Machine and Die Company has
designed, built and sold a combination
5-layer yellow jacket laboratory blown
and cast film line to the Advanced and
Applied Polymer Processing Institute in
Danville, Virginia.
This system is based upon new Yellow
Jacket die technology that is capable
of producing 5-layer blown and cast
plastic film in A-B-C-B-A and other
configurations.
The line can process polyolefins such
as LDPE, LLDPE, and HDPE, barrier
materials such as EVOH, and adhesives
for tie layer applications.
It is ideal for rapid development of
multi-layer structures for subsequent
testing, while using small amounts of
raw material, utilising 5-Layer blown
film stack type die and a 5-Layer
feedblock and cast film die.
The line consists of three 1" 24:1
yellow jacket extruders, dies, blown
film takeoff, cast film takeoff and torque
controlled winder.
The new line is capable of up to 12"
layflat blown film and 8" wide cast film.
Full instrumentation, including digital
auto-tune temperature controls and
melt pressure indicators are part of
each extruder.
The line includes a PC-based data
acquisition system that interfaces
to each extruder control panel and
to record process parameters for
statistical analysis, create trending
plots and perform recipe storage.
The Advanced and Applied Polymer
Processing Institute is a full-service
polymer processing and research
centre.

Fast wire processing
North America OMCG, Inc specialises
in machinery for wire and metal strip
processing.
The company’s CNC-61 multi axis fast
wire bender is used for forming wire
from 1mm to 7mm, and can perform
22 flat bends in 7.8 seconds, or eight
3D bends in 7 seconds. The system
features easy programming for the
input of wire parameters, and allows
two to four different bend radii.
Options include chamfering and
grooving, with parts made in sequence
using the position unload manipulator
to place them in fixture for assembly,
welding or inspection. The machine
can process strip, flat or square wire,
and if holes are required, a press head
can be added.
OMCG’s range of CNC machines can
handle wire up to 5/8" diameter, and
for higher production requirements
the company can also supply slide
machines.

Machine is a big bonus for RG
The purchase of a new swivel
bending machine will allow UK
company RG Attachments to
form a variety of shapes from
large sheet metal.
This task had previously been
unavailable for the Leicester-
based company who will now
find the machine especially
useful in the primary stages
of Tapeformer production,
whereby large metal sheets
need to be chopped and
formed into smaller, more
manageable pieces.
The new purchase will allow a
higher quality of Tapeformer
to be produced, especially for
larger cable sizes. RG have
been producing Tapeformers
for more than 25 years,
and they are used by cable
manufacturers to fold a variety
of insulating material around
cable cores before entering the
final jacketing stage.
The Tapeformer is positioned just before the extruder head and guarantees
precision folds. With an extensive selection of models and folding profiles
the Tapeformer is manufactured to your exact requirements. They can be
used with many insulating tapes including Mylar, paper and metalised foils
and can insulate a wide range of cables including LAN, power, telephone,
communication and automotive cable.
