drive motor
The motor that provides the necessary motion, usu-
ally a turning motion, for any particular component or
components�
energy source
Any source of electrical, mechanical, hydraulic, pneu-
matic, chemical, thermal, or potential energy�
emergency stop
A line status in which all machinery is stopped and
operation is suspended� Emergency stop conditions
occur when an emergency stop button is pressed or a
fault occurs in a machine�
fault
A condition whereby a machine’s operation is sus-
pended after a problem has occurred with a machine
or the line� After the problem has been corrected, the
machine usually must be reset before it can be restart-
ed� A reset is a precautionary step that helps to ensure
safe operation�
field device
A sensor that provides input to a programmable logic
controller, such as a photoeye, limit switch, or proxim-
ity sensor�
flash point
The temperature at which the film begins to melt.
flight length
The distance between two adjoining pushers on the
infeed chain� Also called the infeed pitch�
gauge
(1) The film thickness or (2) an instrument used for
exact measuring or testing�
gear
A toothed machine part, such as a wheel or cylinder,
that meshes with another toothed part to transfer mo-
tion to other machine components�
gear box
A metal enclosure housing a group of gears and shafts�
Gear boxes are usually sealed and filled with lubricant.
guards
Shields that protect the operator from dangerous
parts of a machine or system�
gussets
Tucks made in the sides of a film tube to ensure an

height
The distance from the base of an object to its top�
home position
The location a machine component returns to while
waiting to begin a cycle� A component’s resting posi-
tion�
infeed
The location where product or containers enter a ma-
chine or packaging line�
infeed pitch
The distance between two adjoining pushers on the
infeed chain. Also called the flight length.
jog
To advance a machine through its cycle manually by
pressing and holding a JOG or RUN button� The ma-
chine usually will run at a slow, preset speed� An op-
erator usually jogs a machine to align its components
or to ensure the machine is ready to work at normal
speeds�
leading edge
The downstream edge of a product or package�
length
The measure of the base of an object along its greatest
dimension� Usually a measure of how long something
is�
limit switch
A mechanical sensor that detects the presence or
absence of an object by making or not making contact
in a mechanical switch�
lock
A lock provides protection by holding an energy isola-
tion device in the safe position, thus preventing the
equipment from becoming energized�
