Forbo-Trimmer application possibilities
The Forbo-Trimmer is designed to remove factory edges from
linoleum, to cut strips and to cut seams ready to fit. The Forbo-
Trimmer may be used with such linoleum products as Marmoleum,
Artoleum, Walton, Desk Top, Corklinoleum and Bulletin Board, as
well as with homogeneous vinyl products.
Adjusting the Forbo-Trimmer
Arranging the knives
Which type of knife blade is to be placed in the Forbo-Trimmer
depends on the product for which it is to be used:
linoleum products such as Marmoleum, Artoleum and Walton
are first scribed with a straight blade and then cut with a
hooked blade. These two blades should therefore be arranged
behind one another in the Forbo-Trimmer;
for homogeneous vinyl products, only a hooked blade is used
and it should be placed in the rearmost position in the
Forbo-Trimmer;
for Corklinoleum and Bulletin Board, only a straight blade is
used and it should be placed in the
rearmost position in
the
Forbo-Trimmer.
The casing needs to be removed in order to arrange or replace
blades. The plate positioned against the blades should then be
removed, after which the blades can be positioned or replaced.

Position of the base plate
The position of the base plate must be adjusted depending on
which product is to be cut with the Forbo-Trimmer:
- linoleum products such as Marmoleum, Artoleum, Walton and
homogeneous vinyl products must have approximately 1.5 mm
more space in the opening of the Forbo-Trimmer.;
- with Corklinoleum and Bulletin Board, the opening between
the base plate and the frame needs to be.approximately
10 mm, so that the straight blade does not protrude from
under the base plate.
The position of the base plate may be altered by loosening the
two screws on the side of the Forbo-Trimmer. To make a quick
adjustment, a piece of floor covering may be inserted into the
trimmer on top of which can be placed a few metal shims with a
combined thickness of 1.5 mm (which is the combined thickness
of two blades). When the correct position has been achieved,
the screws may be refastened.
Parallel and horizontal position of base plate
It is important that the base plate is parallel to the frame of
the Forbo-Trimmer. The base plate is to some extent adjustable
sideways. To get the settings right at the beginning, proper
sideways adjustment of the base plate is essential.
The procedure is as follows:
- Remove the casing and the plate positioned against the blades;
- Place two hooked blades in the Forbo-Trimmer;
- Replace the plate against the blades;
- Unscrew the two screws at the bottom of the base plate;
- Push the base plate snugly against the blades;
- After adjustment, the correct blades may be positioned,

Left-handed and right-handed use
Both left-handed and right-handed people can use the Forbo-
Trimmer. To this end, the blades can be placed in the correct
cutting direction and the casing can be turned around. For
right-handed use, the blades should be positioned on the right,
and for left-handed use, on the left.
Working with the Forbo-Trimmer
Cutting clean
When installing linoleum, one should always remove the factory
edges. This is called 'cutting clean: When doing so, the strip of
floor covering is undercut. This canbe done in one go by sliding
one or more filling strips into the Forbo-Trimmer in such a way
that 15 mm is cut from the floor covering; Bend the filling
strips a little before inserting them into the Forbo-Trimmer, so
that they are wedged tightly in position.
Cutting seams
The Forbo-Trimmer may be used to cut seams in one go.
Cut the first length of floor covering on three sides ready to fit,
and cut it clean on the side which is to be positioned against
the second length of floor covering. Stick this length into
position and roll it. Now cut the second length of floor covering
ready to fit. This can be done as follows:
- Clean cut the second strip at the seam side over a length of
approximately 15 mm and place it with the clean-cut portion
against the first length of floor covering;
- Draw a line on the floor along the other longitudinal side of
the second length:
- Cut the transverse sides of the second length of floor covering
ready to fit;
- Position the Forbo-Trimmer and cut the seam.
When cutting seams in linoleum products, it is also possible to
use the Forbo-Trimmer only for scribing and to use the hooked
knife for cutting. This will prevent the floor covering from beco-
ming unusable if• the ForbO-Trimmer slips.
When cutting seams, it is important to exert substantial lateral
pressure on the Forbo-Trimmer, so that the base plate accurately
follows the edge of the bottom strip of floor covering.
Cutting strips
The Forbo-Trimmer can be used to cut-strifis
—
of various widths
(i.e. 5 mm, 10 mm, 15 mm, 20 mm, 25 mm and 30 mm). To do
so, one or more filling strips may be used. Each strip will have
an overcut and an undercut side, which should be kept in mind
when sticking the strips into position.
If seams are not welded, they can be cut to fit against each
other tightly. After cutting seams in linoleum products, a small
gap the thickness of a business card should be left so that after
sticking and expansion, an almost closed seam is achieved.
If seams are welded, it is useful to allow a space approximately
1 mm wide along which to guide the Forbo-Groover or a slotting
machine. For this purpose, the base plate may be adjusted
slightly in a horizontal direction.
