Operation 23
6. System Speed Control — The conveyor speed control dial located below the E-
Stop on the electrical control box allows speed adjustment for the system. The
Infeed and Exit Conveyors, Scrap Chain, and Power Film Unwind are all on a
single speed control because they must all be synchronized when running.
7. Scrap Chain Jog — This is a black palm button located on the electrical control
box on the side toward the infeed conveyor and near the bottom. Once film is
inserted into the scrap chain pinch rollers, use this button as necessary to jog the
scrap chain forward to engage the scrap film.
8. Knob for Raising and Lowering the Seal Head — This knob is located beneath
the electrical control box, above and behind the air filter-regulator-lubricator.
NOTE: Use this knob only when the system is in head setup mode.
CAUTION! When making adjustments for product height, make sure the
seal head seat is all the way down in the lowest position
before lowering the seal head to avoid causing the seal head
to collide with the seal head seat.
Other Features
Film Unwinder — The Film Unwinder is located behind the Product Infeed Conveyor
and Film Separator / Inverter area, behind and to the right of the enclosed L-sealer
area. A roll of film is loaded on the Film Roller Shaft at the bottom of the Film Unwinder
and film is pulled by the Drive and Pinch Rollers, past the Pin Perforator, and routed up
through the Dancer Roller, Idler Rollers Centering Roller and Separator Rod, to the Film
Inverter.
Pin Perforator
— The pin perforator is a special roller in the film unwinder that creates
small holes in the film to allow air to escape during shrinking. The pin perforator must be
synchronized with the film during normal operation in order to make the holes and not
damage the film. The pin perforator must be disengaged by lifting it while loading and
routing the film.
Rubber Drive Roller and Pinch Roller — The Rubber Drive Roller and Pinch Roller
are also special rollers in the film unwinder. The Pinch Roller holds the film against
Rubber Drive Roller to provide the necessary traction to allow the Rubber Drive Roller
to pull the film off the Film Roll and feed the film to the Film Inverter. The Pinch Roller
must be lifted in addition to the Pin Perforator when loading and routing film.
Film Brake
— The Film Brake is located at the infeed end of the Film Roller Shaft and
creates a drag that maintains tension on the film as the film is dispensed. The operator
should from time to time re-check the setting of the film brake for proper tension. The
film brake’s purpose is to reduce overruns or slack in the film.
Film Inverter — Upper and lower film is separated by a rod at the top of the Film
Unwinder.
