saw." The Defender 4000 utilizes the fastest
camera available for the application with a
total processing time of 4 milliseconds. (Total
processing time means that the camera will
take a picture, analyze it, decide if the image
is good or not and tell the saw to stop-all in
.040 seconds.)
"A normal vision system's processing time is
somewhere around 50 to 100 milliseconds,"
Guynn says. "What I found was, at that speed,
when you move a hand in quickly towards
the blade, it may or may not catch it."
Along with the camera's speed of processing,
the saw's exclusive visual glove detection
system detects a special colored glove worn
by the operator. Once the camera detects
the glove in a pre-determined zone, the
system activates the braking mechanism to
stop the blade immediately, greatly reducing
unintended or inadvertent contact with
the blade. The operator can wear cotton or
rubber gloves that are verified by the patentpending detection system before every start
up to ensure proper personal protective
equipment (PPE) is being worn.

DEFENDER PC1500 POULTRY CUTTER
The Defender PC1500 Poultry Cutter utilizes
the same servo-driven braking mechanism
and a conductive glove detection system
without the vision system. Guynn says the
Defender PC1500 spins with significantly less
inertia, allowing the blade to stop faster. No
camera simplifies the whole unit.
"It uses the conductive gloves, just like the
larger Defender 4000 Band Saw. So, the
operator would wear the conductive gloves
and if the blade touches the conductive
gloves then it's going to stop," Guynn says.
"Basically, it alleviates the operators from
having to wear chain mail or metal gloves

Available options on the Hollymatic Defender

or thimbles because it stops in under 8
milliseconds."
Hollymatic's two Defender saws fulfill a
need in the meat and poultry processing
industry for the next level of safety. For
decades the industry viewed the dangers
of processing floors as the nature of the
business. Hollymatic's development of the
Defender 4000 and Defender PC1500, and
the adoption of new attitudes by companies
such as Tyson Fresh Meats, have begun to
shift those views and change that culture.

AMPUTATION REDUCTION
Band Saws and Poultry Cutters in the
processing industry possess many inherent
dangers and pose a serious threat to both
worker safety and food safety throughout
the nation's meat and poultry processing
plants. The use of saws to cut meat creates
an environment wherein the slightest misstep has the potential for injury and the
amputation of fingers or hands.
The Occupational Health and Safety
Administration (OSHA) issued a California
processor a citation after an investigation
into an amputation revealed a guarding
violation had occurred. While cutting meat,
the employee neglected to adjust the guard,
which was just two inches above the product.
OSHA issued a Connecticut processor
multiple citations after an employee at
