Xerox 4000 for Books With Narrow Inner Margins
The rumor that the Xerox 4000 photocopier is no longer available
is untrue: Jan Merrill-Oldham of the University of Connecticut in
Storrs (203/486-2520) just bought one. This model allows the book to
remain open at only a 900 angle while being copied.

Literature has been collected from three (the three?)
manufacturers or distributors of machines for sealing polyester
encapsulations: the Minter/Malosh ultrasonic welder, the CRI
Polyweld and the University Products Radiowelder. They are described
below in the suppliers' own words.
- Minter/Malosh Ultrasonic Welder. Polyester encapsulation
has become the most widely accepted technique for the preservation
of fragile documents. Ultrasonic welding is one method of sealing
the edges of two sheets. Ultrasonics is a process that is widely
used in the plastics industry for the assembly of parts. This method
of sealing has been available to the conservation field for the past
The basic principle is friction. Standard 60 cycles per second of
electrical current is increased by a generator to 40,000 cycles per
second. This electrical impulse is converted to a mechanical
vibration which is transferred through the tip of what is called the
horn. Opposite the horn is an anvil. With the two sheets of
polyester between the horn and the anvil, a weld is produced by the
vibration or hammering action. [An earlier article with diagram is
in the April 1980 issue of AN.]
The first machines of this type required the critical adjustment
of a micrometer to set the gap between the hero and the anvil.
Recent improvements, however, have eliminated this rather
troublesome operation. Now the welding head is mounted on a
self-adjusting slide. The welding head is transported along shafts
by a variable speed reversible motor which is controlled by a foot
switch. A magnetic rubber blanket holds the polyester and the
document to a stainless steel work surface during the welding
operation. The magnetic blanket also eliminates any air that might
become trapped inside. The machine is 25" x 48" x 12" overall, while
the work surface is 15" x 48". There are two auxiliary tables--one
9" x 48" and the other 15" x 4B"--to permit the encapsulation of
documents up to 38" square. However, larger documents can be
encapsulated by simply repositioning the material.
Another recent improvement has been a modification which allows
the weld to be made up to 9" from the edge of the polyester. The
material can also be rolled, if necessary, to weld to the center of
a larger sheet. A special modification of the basic model would
permit even deeper welds.
Ultrasonics can easily weld two sheets of 2, 3, 4, or 5 nil
polyester (Do Pont Mylar Type 0 or ICI Melinex 516). For larger
documents that require additional support, a sheet of 2 or 3 mile
can be welded to a sheet of 5, 7 or 9 mile.
The ultrasonic welder was designed primarily for the
encapsulation of book leaves and archival documents. It takes less
than two minutes to completely encapsulate an 8½" x 11"
document in 3 nil polyester, allowing for a binding stub. The
machine will pay for itself after approximately 6,000 items are
- Model B-50 Polyester Sealing Machine, from Conservation
Resources International, Inc. We designed the
PolyweldTM B-50 specially for use in the conservation
laboratory. We talked with conservators in large institutions,
commercial operations and small university workshops. There were no
conflicting requirements among the people we interviewed, and, not
surprisingly, there was considerable concurrence among the
conservators about features they did want. These features included
simplicity, reliability, speed of operation, the ability to
encapsulate 48" maps, and economy. We feel the Model B-SO excels in
all of these areas.
- [It] can seal 100" per cycle, with a maximum single length of 50
inches.... The complete sealing cycle, start to finish, is only
3½ seconds. This means you can produce, for example, ten 6 x
9" polyester folders in one 3½ second cycle.... Two people
performing the same (or different) task can use the machine at the
We have eliminated the need to resort to cooling fans (which tend
to blow the polyester sheets out of alignment before they can be
sealed) or cumbersome cold water pipes or any other superfluous
devices to cool the polyester before you can remove it and start
We use a special coating on the Model B-50 to eliminate the
static electricity buildup in the polyester film. This makes the
polyester much easier to handle, which results in increased
efficiency and eliminates shocks to the operator.... We have
provided separate pressure clamp alignment and sealing cycle
operations. This allows you to put 10 or 20 items in the machine,
align and clamp them, and still make a quick visual check before
pressing the sealing cycle button.... It is easy to operate. Plug
the machine into an ordinary wall outlet, insert two or more
polyester sheets and push the cycle button. There is no special
training period or skill required to operate this machine.
It is super reliable. We were able to continually refine this
machine in our factory over a considerable period of time, while
producing tens of thousands of seals.
