The Model Number 7 Book Stitcher is a combination light and heavy duty stitcher
designed to staple both flat and saddle work ranging in thickness from a few sheets to
7/8" (22.2mm).
The recommended wire sizes to be used on the Number 7 Stitcher are as follows:
round wire - 28 to 24 and flat wire - 20 x 24, 20 x 25, and 21 x 25. The above wire
sizes can be used without changing parts. However, for heavy flat work it is
recommended that the special flat work Driver be substituted for the standard Driver.
The Number 7 is easily adjustable for changing from saddle work to flat work by
means of the tilting work table. Figure 1 shows the stitcher set for flat work operation.
An adjustable work guide and adjustable work stops are easily attached to the work
table and provide for accurate registering of flat work for uniform spacing of staples.
When the work guide is not being used it can be attached to the right side of the
stitcher's frame, where screw holes are provided for attaching the guide (using the
same screws which attach it to the work table), thereby providing a convenient storing
place for the guide. In addition, work table extensions, both front and back, are
provided to accommodate the larger sizes of work to be stitched.
The Model Number 7 is foot-switch operated and is belt driven by a 1/3, HP motor,
making possible operating speeds up to 125 stitches per minute. The motor is
mounted on an adjustable bracket which can be raised or lowered for adjusting the
tension of the driving belt. The machine driving mechanism is thoroughly shielded
thus preventing the possibility of personal injury.

Operating Adjustments
The quality and quantity of work that can be stitched on the Number 7 machine is dependent upon
the operator making the various operating adjustments as accurately as possible. The following
illustrated instructions and information are provided so that the operator will clearly understand how
to make the required operating adjustments.

To open the stitcher head Door, press the Door Latch (1) to the right, thereby releasing the Latch
from the Latch Catch and permitting the Door to swing to an open position (shown by the dotted
line in Figure 2). To close the Door, first
check that the machine is at the top of its
stroke (the Supporter (2) will be at a
forward position), then depress the
Supporter back to its retracted position
with one hand and close the Door with
the other hand while compressing the
Latch (1) until it catches in the Latch
Catch.

Turn the thickness adjustment handwheel (1) counter-clockwise (to the left) until the Column Gauge
(2) has raised sufficiently to allow a sample of work to be stitched to be inserted between the Gauge
and the Gauge Shelf, as shown in Fig. 3. With work held in this position, turn the handwheel (1)
clockwise (to the right) until the work is firmly clamped between the Gauge (2) and the Gauge Shelf;

then turn the handwheel to the left, raising
the Gauge just far enough to permit work
to be withdrawn from between the Gauge
and the Gauge shelf. After withdrawing
the sample work, turn the handwheel to
the right until the Gauge has returned to
the point at which it clamped the work.

* Note: 21x25 flat wire can be used for Heavy Saddle applications but it is not
recommended. If 19x21-1/2 flat wire is required, contact your Graphic Arts
Representative for the recommended parts.
Open the Stitcher Head Door (1).
Pass the wire from the Spool over
the Wire Guide Spring (2),
threading the wire between the
Guide Studs on the Guide Spring
and through the Oiler Felt in the
Retainer (not shown). Thread the
wire between the Rolls of the two
sets of Wire Straighteners (3) and
(4). Pass the end of the wire behind
the Wire Clip (5) and then pull the
wire down until it extends to just
below the Wire Cutter Holder (6).
Push the Wire Holder Slide (7) to
the left. With the Slide held in this
position, lay the wire well back in
the slot (8) in the Wire Cutter Holder
then release the Slide (7) allowing it
to close over and retain the wire in
the slot (8). Slide the Wire Retainer
(9) up, thereby uncovering the
groove in the Wire Guide (10). Lay
the wire in the groove and then slide
the Retainer (9) down securing the
wire in the groove. Turn the
machine over manually until the
wire
automatically falls in place between
the Moveable and Fixed Grips (11) and (12).
The wire is now threaded in the Head. However, before operating the Stitcher under power, turn the
machine over manually a few revolutions and observe that the wire is feeding freely and is being
cut off by the Cutters in the Cutter Holder. Then close the stitcher head door and check that the wire
is feeding in a straight vertical line, as directed in the following paragraph.

In order to insure continuous
operation of the Stitcher, it is
important that the wire when
being fed into the Swivel,
enters in as close to a
straight-vertical line as
possible. To check this
condition and make the
necessary adjustments,
proceed as follows.
Disengage the Swivel Spring
(1) from the Swivel (2) and
withdraw the Swivel from its
Bushing (3). Turn the
machine over manually and
observe by looking directly
into the Swivel Bushing (4)
that wire is being fed in a
vertical line, as shown in
insert Figure 6. If the wire is
feeding to the left or to the
right, turn the Lower Wire
Straightener Eccentric
Handle (5) clockwise or
counter-clockwise as
required, until wire feeds in a vertical line. If wire is feeding in a straight line with respect to
the left and the right but tends to curl forward or backward, turn the Upper Wire Straightener
Eccentric Handle (6) until this condition is remedied. After the necessary adjustments have
been made, replace the Swivel in its Bushing and attach the Swivel Spring.
Wire Straightening (Figure 6)
Do not slam door shut, or attempt to force door shut while
cycling machine or with machine positioned at bottom of stroke.
Failure to comply with this may result in damage to the stitcher head.
rCAUTION
!
Always disconnect the power supply before
making any adjustments or servicing the stitcher.

If staple is cut off center causing one leg to be longer than the other, the left leg of the staple can be
shortened or lengthened as follows. Loosen but do not remove the two Wire Feed Adjustment Rack
Screws (1) permitting the Adjustment Rack (2) to be moved up or down. If a shorter left leg is
required, move the Adjustment Rack (2) up slightly. If a longer left leg is required, move the
Adjustment Rack down slightly.
After positioning the Adjustment Rack,
tighten the Adjustment Rack Screws (1) and
turn the machine over a few revolutions to
check the stitches. If the staple is still off
center, repeat the preceding steps until a
perfect stitch is obtained. With a little
experience, the operator will soon learn how
much to raise or lower the Adjustment Rack
to obtain the correct staple leg length. After
the final adjustment has been made, securely
tighten the Adjustment Rack Screws (1).
