METAL STRIP BRUSHES
METAL STRIP BRUSH DESIGN
SHEET
Flex-guard's metal
strip brushes are simple to manufacture, ideally suited to highly
automated, high volume production and, after basic manufacture, can be
easily coiled or formed into special shapes and configurations and
combined into special assemblies. Tooling costs are seldom incurred
unless special forms, trims and channel shapes or secondary assembly
tooling is required. Flex-guard® manufactures metal strip brushes
by laying filaments (natural, synthetic or wire) over a continuous metal
channel while it is being formed into a "U" shape. A binding wire is
forced down into the partially formed channel, forcing the bristle
material down to the bottom of the newly formed channel. The bristle
material aligns vertically as the strip is closed together. Brushes are
then trimmed to the required height and cut to length automatically.
Lengths are virtually unlimited. Pieces as short as 3/8" are possible in
the smaller strip sizes and lengths up to 12 feet are easily
manufactured.
Metal strip brushes can be manufactured in a wide range of standard and
special configurations. The metal holding channels (of steel, stainless
or brass) and metal or plastic binding wires offer malleability for
forming and coiling yet provide consistent dimensional stability and
repeatability with structural integrity. Virtually any type of filament
can be inserted into the metal channel as well as solid materials such
as felt, plastic and rubber; alone, or combined with the bristle
material. The advantage of
Flex-guard's metal
channel strip brush construction is that,
along with the wide range of design possibilities,
metal strip brushes require
minimum labor and low tooling costs for high output production on a
highly repeatable basis.

CHANNEL MATERIALS
Different manufacturers may use the same Size, Letter or Number for
metal channel strip brushes.
There are often however, significant differences in the actual dimensions after
forming. Thus, if the metal channel strip brush is to
be inserted into an extrusion, holder, bracket assembly or mating part; it
should be submitted and retained by Flex-guard to be used as an additional gauge
to insure proper fit.
Flex-guard's
unique "h" back metal strip brushes combine brush and mounting flange into one unit.
For the OEM designer, maintenance or process engineer, "h" back strip brushes
eliminate parts, facilitate assembly and reduce cost and installation time. A
wide range of special options and additional sizes are available to the OEM
user. In addition, five standard size "h" back brushes with a variety of bristle
materials are available from stock.
OPTIONAL CHANNEL
SHAPES
Many styles and shapes are possible in special
metal channel strip brushes. Tooling for forming tools
would be required. Some of the special shapes we have produced are:
