Eriez offers an extensive range of equipment to textile and nonwoven
producers to both detect and remove metal contamination of all types from
the production process, thereby reducing the risk of machinery and product
Magnetic separation devices in the form of Magnetic Tubes
or Rods, Plate and Bar Magnets remove ferrous metals and
are often installed at the raw material stage. Such magnets
are available in a wide range of strengths and sizes.
Choosing the optimum magnet for the job depends on the
application parameters and the type of metal to be
During the production process, expensive calenders, rollers and cutting
mechanisms can be protected by use of high sensitivity aperture type
E-Z Tec Metal Detectors. These
can be employed to detect metal
objects of 1mm (0.039") and
sometimes less in diameter.
The final product can be checked for small metal inclusions such as broken
needle tips by using the Eriez Model SS METALARM 7000 Single Sider
Metal Detector which has the ability to spot metal fragments in any type of
The METALARM 7000 incorporates a
patented search coil system that not only
yields a high level of sensitivity – typically a
1mm (0.039") sphere – but also has two
significant advantages over existing systems.
The first is that it can be installed at close
proximity to moving metals without losing
sensitivity or being falsely tripped. This in turn means that the detector can
be fitted into a wide range of machines with virtually no modification, and in
positions not previously possible to accommodate such equipment.
Second, the METALARM 7000 will also indicate the position of any metal
detected within a 250mm (9.8") length, if required. This saves the user having to visually check materials – up to five metres (16.4 ft) wide – which
can be very time consuming and costly in terms of production downtime.
In addition, Eriez manufactures metal detector conveyor systems for
checking finished garments and primary products such as ribbons, elastic,
shoulder pads, etc.
Often used in tandem with conveyor and aperture type
metal detectors is the HandyTec Hand-held Detector.
This is a simple, portable device for pinpointing the exact
position of metal down to 1mm (0.039") in size and is often
used for routine inspections to check finished items for
pinheads and any other lingering metallic objects.
