BORE-Inside diameter of a core or hub for a roller
brush.
BRISTLE-Natural animal fibers used to create brush tufts.
BRUSH PART-The length of the brush area on a block or core. Brush
Part can be the same or shorter then the Overall Length.
CORE DIAMETER-Diameter of a cylindrical brush core.
CRIMPED-Filament that has
been embossed with a wave pattern. Crimp is measure by amplitude and frequency.
CUT END-Part of a twisted-in-wire brush where
the wire has been flush cut at the brush part end.
FERRULE-A steel tube, seamed or seamless, that gathers and binds the bristle in
a paint brush.
FIBER-Any material used to create a brush tuft, but the term is normally reserved for vegetable fibers such as tampico
and palmyra.
FILAMENT-Extruded synthetic fibers used to create brush tufts.
FINGER LOOP-Part of a twisted-in-wire brush that has a loop
in the end opposite the brush part to accomodate pulling with the index finger.
FLAGGED-Filament that has been run through a series
of knives to splinter the ends and produce a softer tipped brush.
FLARE-1. The angle of a tuft respective of the block or core.
A tuft perpendicular to the block has a flare of 0. Typically, this is used as a descriptor on floor and hand brushes.
2. The spread of the bristle in a tuft. Tufts can be cylindrical or conical, the spread at the bristle ends is called the tuft
flare.
HOLE DIAMETER-The diameter of a tuft hole in a block or core.
INSIDE DIAMETER-The diameter of the inside of a metal grip coil
brush.
KEYED HUB-A core hub with a key and two set screws.
LEVEL-Filament that has been extruded straight, without crimp.
METAL GRIP
ROLLER (MGR)-Metal-grip strip brush that has been coiled onto a cylindrical core.
METAL GRIP STRIP (MGS)-Continuous brush that is formed
by placing filament in a dove tail shaped metal channel and held in place with a retaining wire.
OVERALL DIAMETER-The diameter of a
cylindrical brush measured at the filament ends.
OVERALL LENGTH-The length of a brush, usually measured as the length of the block
or core.
PATTERN-The distance between tufts usually given by a row and column distance measurement for block brushes and by tufts per
circumference and spacing for cylindrical brushes.
PITCH-The distance between wraps on a coil brush. See also Wraps Per Foot.
PLASTIC
BACKED STAVE (PBS)-A tufted strip brush with a plastic backing.
POLY CORE ROLLER (PCR)-A cylindrical brush with a plastic core.
POLY
STEEL CORE ROLLER (PSCR)-A cylindrical brush with a combination plastic, inner steel core and hubs.
ROLLER BRUSH-Any cylindrical brush.
STANDARD
KEY-A metal pin used to lock a hub to a shaft by positioning the key halfway in between. Standard keys are determined by the
diameter of the shaft or bore.
STAVE BRUSH (PBS, WBS)-A tufted brush with one or more rows of tufts in a long rectangular wood or plastic
block.
STRIP BRUSH-A long brush either tufted or metal-grip in construction and usually without flare.
TRIM-The length of the brush
filament from the block or core.
WALL THICKNESS-The thickness of a cylindrical core wall.
WOOD CORE ROLLER-A cylindrical brush with
a wood core.
WRAPS PER FOOT-The number of wraps in a foot for a coil on a cylindrical brush. See also Pitch.
