Section 1—Introduction
About this Manual
Valco Cincinnati has prepared this manual as an aid for installing, operating, and servicing the VC350A Flexoseal®
control (Figure 1). This manual provides specific information about the unit, and general guidelines and references
when discussing other equipment such as glue systems, scanners, encoders, and dispensing valves. If you need more
information, contact your Valco Cincinnati representative.
Product Description
The VC350A Flexoseal® system is an electronically controlled lap-gluing system. Using an enclosed glue system,
the Flexoseal®equipment applies accurate glue patterns to inside or outside laps at speeds of up to 2000 feet per
minute (610 meters per minute). The VC350A applies adhesive directly to the product through glue valves. The
valves deliver a precise, uniform application of adhesive through the system’s fluid-flow-control component. The
VC350A Flexoseal® system is used on corrugated box board processing equipment to produce high-quality seals.
The VC350A Flexoseal®system consists of three main components:
•VC350A control—Control boards, encoder
•Glue delivery system—DD-1 pump, air filter/regulator, glue filter, glue-pressure regulator, gauge, and
gaugeprotector
•Glue application system—Glue station, scanner, glue valve, applicator head
Options include:
•Channel II board
•Glue-pressure relief system
•Scanner logic module kit
•JP2000 jam preventer

WARNING! When making adjustments or performing checkout procedures,
stay clear of any moving mechanical parts and do not touch exposed electri-
cal equipment or electrical connectors. OTHERWISE, DEATH OR PERSONAL
INJURY COULD OCCUR.
WARNING! Keep pump cover and electrical enclosures closed except during
setup,service,and checkout procedures.OTHERWISE,DEATH OR PER-
SONALINJURYCOULD OCCUR.
WARNING! Promptly repair or replace all worn or damaged parts. OTHER-
WISE, PERSONAL INJURY OR EQUIPMENT DAMAGE COULD OCCUR.
WARNING! Always wear insulated gloves and proper eye protection when
working around hot-melt equipment. A protective screen around the face is
also recommended. OTHERWISE, DEATH OR PERSONAL INJURY COULD
OCCUR.
WARNING! Purge the fluid pressure from the system before disconnecting
any part of the system. OTHERWISE, DEATH OR PERSONAL INJURY COULD
OCCUR.
WARNING! People with respiratory problems (e.g., asthma, bronchitis, etc.)
should not work in the vicinity of molten adhesive. RESPIRATORY PROB-
LEMS MAY BE AGGRAVATED BY THE FUMES. Do not wear a face mask
when working around molten adhesive. THE MASK MAY TRAP THE FUMES
AND DEATH OR PERSONAL INJURY COULD OCCUR.
WARNING! Keep hot-melt hoses away from walkways and the moving parts
of hot-melt systems. OTHERWISE, PERSONAL INJURY OR EQUIPMENT
DAMAGE COULD OCCUR.
WARNING! The hot-melt unit should be installed so that it can be turned off at
a location away from the hot-melt unit. OTHERWISE, DEATH, PERSONAL
INJURY, OR EQUIPMENT DAMAGE COULD OCCUR.
Cautions
All personnel involved with the installation, operation, and maintenance of the equipment must read and thoroughly
understand the following cautions:
CAUTION! Never hose or steam-clean the unit. If the surrounding area is
cleaned in this manner, protect the unit by covering it with plastic or other
waterproofmaterial.OTHERWISE,DAMAGETOEQUIPMENTCOULD OCCUR.
CAUTION! Do not bend hot-melt hoses less than an 18-inch (460 mm) radius.
OTHERWISE, EQUIPMENT DAMAGE COULD OCCUR.
CAUTION! Place Material Safety Data Sheets for the adhesive near the unit.
OTHERWISE,DAMAGE TOEQUIPMENTCOULD OCCUR.
