3M-Matic™ S-857 "L" Clip Applicator, Type 29500
The intended use of the S-857 "L" Clip Applicator is
to apply an "L" clip of Scotch™ brand filament tape
to most box corners.
The machine is designed for installation adjacent to
a conveyor system or on a stand for off-line systems,
the S-857 allows the operator to quickly apply the "L"
clip box closure. When a box is inserted into the
Intended Use
nest, the product paddle is depressed and the air
operating mechanism which applies the "L" clip tape
closure is activated causing the "L" clip to be
automatically applied to the box corner.
The S-857 "L" Clip Applicator has been designed
and tested for use with Scotch™ brand filament
tape.

Specifications
4. Cycle Time:
1.2 seconds per cycle
The cycle time is sufficient to satisfy the majority
of applications. Flow controls (see page 17 – Air
Flow Controls) control the application rate and
return stroke rate of the air cylinder. While these
flow controls can be adjusted for increased
speed, this practice may result in higher
maintenance costs and shorten machine life.

Installation and Set-Up
Receiving and Handling
After the applicator has been unpacked, examine it
thoroughly for any damage that may have occurred
during transit. If damage is evident, file a damage
claim immediately with the transportation company
and also notify your 3M Representative.
Machine Set-Up
Read the installation instructions through completely
before performing the set-up procedure. Refer to
the back of this manual for literature on "Typical
Mounting Set-Up" for the S-857 Applicator.
Mounting – The S-857 can be set up in either of
three taping positions:
Bottom Taping Position – Shown in Figure 2-l.
For application of "L" clip tape seal to the bottom
corner of a box.
Top Taping Position – Shown in Figure 2-2. For
application of a tape seal to the top corner of a
box.
Side Taping Position – Shown in Figure 2-3. For
application of a tape seal to the end of a box.
Three mounting areas have been provided on the
S-857 main frame. A mounting bracket (with two
holes) and a single mounting hole on the left side
and two mounting holes located on the front of the
machine. It is suggested that the S-857 be mounted
securely at any two of these mounting areas.
Note: When mounting the unit, always align the
top surface of the nest parallel with the work
surface. When mounting the unit for side taping
align the nest perpendicular to the work surface.
It is suggested that a secondary height adjustment
be provided for head adjustments as referred to in
the top taping operation section.
Note: The air flow control unit must be
remounted in a vertical position when operating
the S-857 in the top or side taping position.All
additional brackets, fittings and air lines are to
