INSTALLATION PROCEDURE
1. EXERCISE CARE WHEN HANDLING THIS MACHINE. A SUDDEN JOLT OR JAR MAY CAUSE
SERIOUS DAMAGE.
2. DO NOT REMOVE THE SHIPPING SKID UNTIL MACHINE HAS BEEN MOVED TO A POINT OF
INSTALLATION. THE SKID IS DESIGNED FOR EASY AND SAFE HANDLING OF YOUR
MACHINE.
3. RAISE OR LOWER THE MACHINE TO THE DESIRED OPERATING ELEVATION USING THE
LEVELING JACK SCREWS AND LEVEL THE MACHINE.
4. A GREAT DEAL OF TROUBLE MAY BE CAUSED IF THE ELECTRICAL CURRENT IS SUPPLIED
BY LINES WHICH ARE NOT HEAVY ENOUGH. IF THIS OCCURS, THE MOTOR AND
CONTROLS CANNOT OPERATE AT THEIR FULL CAPACITY AND OVER HEATING MAY
RESULT. A SIMILAR CONDITION WILL EXIST IF POOR ELECTRICAL CONNECTIONS ARE
MADE. IT'S THEREFORE WORTHWHILE TO MAKE SURE THAT EVERYTHING IS
ELECTRICALLY CORRECT.
5. ELECTRICAL POLARITY MUST BE SUPPLIED TO THE MACHINE EXACTLY AS SHOWN ON
THE ELECTRICAL DIAGRAM. POWER MUST BE SUPPLIED TO (L1) SIDE OF THE CIRCUIT
AND THE (L2) SIDE WILL BE NEUTRAL. IF THIS IS NOT CORRECT, THE CIRCUIT
PROTECTORS (ECP 1) WILL TRIP OUT BECAUSE OF A SHORT CIRCUIT.
6. THE COMPRESSED AIR SUPPLIED TO THE MACHINE SHOULD BE CLEAN AND DRY, AS
THE FILTER IS ONLY MEANT TO REMOVE MINOR PARTICLES OR SLIGHT AMOUNTS OF
MOISTURE. DIRT OR MOISTURE IN THE AIR LINE CAN CAUSE THE ERRATIC OPERATION
OF CONTROL VALVES.
7. CONNECT THE AIR SUPPLY TO AN AIR SOURCE WITH A MINIMUM LINE PRESSURE OF 80
PSI.
8. BEFORE STARTING THE MACHINE, LOAD THE TAPE CARTRIDGE WITH TAPE AND THREAD
THE TAPE. SEE THREADING DIAGRAM ON TAPE UNIT.
9. FOR PROPER START-UP PROCEDURE, SEE THE START-UP PROCEDURE SECTION OF
THIS MANUAL.
10. SAFETY GLASSES SHOULD BE WORN WHEN WORKING ON OR AROUND MACHINE.

SEQUENCE OF OPERATION
INITIAL CONDITIONS:
A. MAIN AIR VALVE TURNED ON.
B. POWER CORD CONNECTED.
C. EMERGENCY STOP BUTTON IS PULLED OUT.
D. SELECTOR SWITCH IS SET TO “AUTO”.
E. HOPPER HAS BLANKS PROPERLY LOADED.
GENERAL SEQUENCE:
1. PRESS THE "START" PUSH-BUTTON (PB1). MOTOR CONTACTOR (K1) IS ENERGIZED
AND THE MOTOR STARTS.
2. NORMALLY OPEN CONTACT (K1) CLOSES, PROGRAMMABLE CONTROLLER IS
ENERGIZED, AND THE SEQUENCE STARTS.
3. THE CASE PUSHER (SOL 4) AND VACUUM TROLLEY (SOL 5) GO TO HOME POSITION.
4. AS SOON AS PROXIMITY SWITCHES 1 (TROLLEY) AND 3 (PUSHER) ARE ACTIVATED,
AND PHOTOCELL 3 (HOPPER) IS BLOCKED, OUTPUT 2 ENERGIZES THE VACUUM
VALVE (SOL 2) AND THE VACUUM TROLLEY (OUTPUT 1) MOVES FORWARD TO PICK
UP A BLANK.
5. AT THE TROLLEY EXTENDED POSITION, PROXIMITY SWITCH 2 ACTIVATES (INPUT 1),
ENERGIZING TIMER 4. AFTER A PRE-SET TIME, TIMER 4 TIMES OUT, DE-ENERGIZING
THE VACUUM TROLLEY SOLENOID (OUTPUT 1).
6. THE VACUUM CUP TROLLEY THEN RETURNS TO THE HOME POSITION, ACTIVATING
PROXIMITY SWITCH 1 (INPUT 0), ENERGIZING THE MINOR FLAP FOLDER (SOL 6,
OUTPUT 3).
7. PROXIMITY SWITCH 1 ENERGIZES TIMER 3. AFTER A PRESET TIME, TIMER 3 TIMES
OUT DE-ENERGIZING THE VACUUM VALVE (SOL 2, OUTPUT 2). THE FORMED CASE IS
RELEASED, READY FOR TRANSFER.
8. AS THE CHAIN LUG IS DETECTED BY PHOTOCELL 1 (PC1), THE INTERNAL RELAY 1004
TURNS ON THE CASE PUSHER VALVE (SOL4, OUTPUT 5). THE FORMED CASE IS
PUSHED INTO THE FEED ROLLERS, AND THEN ACCELERATED INTO THE CHAIN LUG
DRIVE.

9. AT THE EXTENDED POSITION OF THE CASE PUSHER, PROXIMITY SWITCH 4 IS
ACTIVATED, ENERGIZING THE INTERNAL RELAY 1003. THIS RELAY THEN DE-
ENERGIZES THE CASE PUSHER VALVE (SOL4, OUTPUT 5), SENDING THE CASE
PUSHER TO THE HOME POSITION.
10. AS OUTPUT 5 IS DE-ENERGIZED, TIMER 6 STARTS TIMING. WHEN TIMER 6 TIMES
OUT, THE MINOR FLAP FOLDER (SOL 6, OUTPUT 3) IS DE-ACTIVATED. THE MACHINE
IS NOW READY FOR THE NEXT CYCLE.
11. REPEAT SEQUENCE STARTING AT GENERAL SEQUENCE #4.
NOTE 1:
THE CASE-ON-DEMAND PHOTOCELL (PC2) IS LOCATED DOWNSTREAM FROM THE MACHINE.
IF THIS SWITCH IS BLOCKED, INPUT 8 IS ENERGIZED AND THE CASE PUSHER WILL NOT
PUSH ANYMORE CASES INTO THE LUG DRIVE UNTIL THE PHOTOCELL IS CLEARED.
NOTE 2:

NOTES: TURN POWER OFF BEFORE MAKING ANY ADJUSTMENTS
TO THIS MACHINE.
REFER TO ASSEMBLY DRAWINGS FOR ITEM I. D.
1. HOPPER WIDTH ADJUSTMENT:
SET POINT: WIDTH OF BLANK + 1/8”
TO ADJUST HOPPER WIDTH, FIRST LOOSEN THE LOCKING CLAMP (ITEM # 19), THEN,
TURN ADJUSTING RATCHET (ITEM # 20) UNTIL THE BLANK FITS LOOSELY (1/8” CLEARANCE)
BETWEEN THE ADJUSTABLE BLANK GUIDE (ITEM # 14) AND THE FIXED BLANK GUIDE
(ITEM # 23). TIGHTEN THE LOCKING CLAMP BEFORE STARTING MACHINE.
2. HOPPER HEIGHT ADJUSTMENT:
SET POINT: 1/2” THE WIDTH OF THE ERECTED BOX
TO ADJUST HOPPER HEIGHT, ROTATE THE HANDLE ON THE TOP OF THE HYDRAULIC PUMP
(ITEM # 10). CLOCKWISE TO RAISE AND COUNTERCLOCKWISE TO LOWER. YOU CAN SET
THIS ADJUSTMENT USING THE SCALE ON THE SIDE OF THE HYDRAULIC CYLINDER (ITEM # 6)
DIVIDE THE WIDTH OF THE CASE IN 2, AND SET THE POINTER (ITEM # 21) TO THAT POSITION
ON THE SCALE. WHEN YOU ARE FINISHED ADJUSTING THIS ASSEMBLY, PUT THE HANDLE
ON THE HYDRAULIC PUMP BACK INTO ITS LOCKED POSITION.
EXAMPLE: IF THE CASE YOU ARE RUNNING IS 10" WIDE, YOU WOULD SET THE POINTER
TO 5" ON THE SCALE.
3. FINGER ASSEMBLIES:
SET POINT: CENTER OF SLOT, 1/4” DEEP
THE TOP AND BOTTOM FINGERS MUST BE POSITIONED IN A MANNER AS TO SLIP THROUGH
THE SLOTS OF THE KNOCK-DOWN CASE AT THE MANUFACTURERS JOINT AND SLIGHTLY
HOLD THE INSIDE REAR PANEL AS THE VACUUM CUPS PULL THE CASE FROM THE
HOPPER. FIRST, SET BOTH FINGERS SO THAT THEY ARE APPROXIMATELY 3/8" FROM THE
FRONT FACE OF THE CASE. THIS IS ACCOMPLISHED BY LOOSENING AND ROTATING THE (2)
SET SCREWS THAT HOLD THE FINGERS. ONCE SET, THIS ADJUSTMENT SHOULD NOT NEED
TO BE CHANGED FOR DIFFERENT BOXES.

TOP FINGER:
SET THE HORIZONTAL POSITION OF THE FINGER SO THAT IT LIES IN THE CENTER OF THE
SLOT. LOOSEN THE RATCHET HANDLE (ITEM # 23) AND SLIDE THE ASSEMBLY BY HAND
THEN RE-TIGHTEN THE RATCHET HANDLE. SET THE VERTICAL POSITION OF THE FINGER
SO THAT APPROXIMATELY 1/4” OF THE FINGER TIP IS IN THE SLOT. VERY WIDE BOXES MAY
REQUIRE MORE FINGER AND VERY STIFF BOXES MAY REQUIRE LESS. MOVE THE FINGER
UP OR DOWN BY LOOSENING THE RATCHET HANDLE WHILE HOLDING THE GEAR KNOB
(ITEM # 13). TURN THE GEAR KNOB TO ACHIEVE THE PROPER SETTING AND RE-TIGHTEN
THE RATCHET HANDLE.
BOTTOM FINGER:
THE BOTTOM FINGER REQUIRES THE SAME SET-UP AS THE TOP FINGER. HOWEVER, ONCE
THE VERTICAL POSITION IS SET INITIALLY, IT SHOULD NOT NEED ADJUSTMENT FOR MOST
OTHER BOXES BECAUSE THE BOTTOM OF THE CASE IS ALWAYS THE SAME DISTANCE FROM
THE FINGER. THE HORIZONTAL POSITION IS SET BY LOOSENING THE CLAMP KNOB AND
SLIDING THE FINGER BY HAND. RE-TIGHTEN THE CLAMP KNOB.
4. CASE PUSHER:
SET POINT: LENGTH OF ERECTED BOX
THE CASE PUSHER/REAR FLAP FOLDER ASSEMBLY WILL BE SET SO THAT THE PUSHER
PLATE (ITEM # 4) IS APPROXIMATELY 1/4" AWAY FROM THE REAR MINOR PANEL OF THE
FORMED CARTON, AS IT SITS ERECTED ON THE BOTTOM FLAP FOLDERS. TO ACCOMPLISH
THIS, LOOSEN THE (2) RATCHET HANDLES (ITEM # 22) AND SLIDE THE ASSEMBLY. ALIGN
THE REAR EDGE OF THE CASE PUSHER FRAME TO THE SCALE EQUAL TO THE LENGTH OF
THE CARTON. TIGHTEN RATCHET HANDLES BEFORE STARTING MACHINE.
EXAMPLE: IF THE CASE YOU ARE RUNNING IS 16" LONG, YOU WOULD ALIGN THE FRAME
WITH 16" ON THE SCALE.
5. VACUUM TREE:
SET POINT: CENTER OF MAJOR PANEL
CASE LENGTH ADJUSTMENT:
THE VACUUM TREE SHOULD BE POSITIONED HORIZONTALLY IN THE CENTER OF THE MAJOR
PANEL (LENGTH OF THE BOX). TO SET, PUSH THE TROLLEY TOWARD THE HOPPER SO THAT
IT IS NEAR THE BLANK. LOOSEN RATCHET HANDLE (ITEM # 39) AND SLIDE THE TREE TO THE
MIDDLE OF THE MAJOR PANEL. RE-TIGHTEN RATCHET HANDLE.
VACUUM CUP POSITION:
THE VACUUM CUPS SHOULD BE SET ON EACH CORNER OF THE MAJOR PANEL TO PROVIDE
THE BEST SUPPORT. TRY NOT TO HAVE ANY CUPS LANDING OVER A SCORE LINE ON THE

BLANK. THE CUPS SHOULD BE OFFSET FROM THE EDGES BY ABOUT 1/4”. WHENEVER
POSSIBLE USE ALL FOUR CUPS TO RUN THE BOXES. TWO CUPS MAY BE USED IF THE
MAJOR PANEL IS TOO SMALL. FOR TALL BOXES (OVER 10”) THE VACUUM POST EXTENSION
MAY BE USED. TO SET, LOOSEN THE CENTER KNOBS FOR VERTICAL POSITION. LOOSEN
THE OUTER KNOBS TO ALLOW THE ARMS TO SWEEP THROUGH THEIR ARC. THIS PROVIDES
BOTH WIDTH AND HEIGHT ADJUSTMENT. BE SURE TO TIGHTEN ALL KNOBS WHEN FINISHED.
TO REMOVE A SET OF CUPS (2), DISCONNECT THE HOSES AT THE QUICK RELEASE
COUPLING, LOOSEN THE CENTER KNOB AND SLIDE THE BAR UP AND OFF THE POST.
IMPORTANT!!!! BEFORE STARTING MACHINE, PUSH THE TROLLEY BY
HAND BACK AND FORTH THROUGH THE FORMING AREA TO CHECK FOR
INTERFERENCE WITH THE FLAP FOLDERS.
6. TROLLEY STOP:
SET POINT: 1/2 THE WIDTH OF THE ERECTED BOX
THE TROLLEY STOP SETTING IS BASED ON THE WIDTH OF THE BOX. IT ALIGNS THE
ERECTED BOX WITH THE LUG DRIVE SYSTEM. THE STOP WILL BE SET TO HALF THE
WIDTH OF THE BOX USING THE SCALE PROVIDED AND THE REAR EDGE OF THE STOP.
EXAMPLE: IF THE CASE YOU ARE RUNNING IS 10" WIDE, YOU WOULD SET THE STOP
TO 5” ON THE SCALE.
7. LUG DRIVE WIDTH ADJUSTMENT:
SET POINT: 1/2 THE WIDTH OF THE ERECTED BOX
TO SET, TURN THE HANDWHEEL ON THE OPERATORS SIDE OF THE MACHINE. TURNING THE
HAND WHEEL CLOCKWISE WILL OPEN THE DRIVE, COUNTER-CLOCKWISE WILL CLOSE UP
THE DRIVE. OPEN THE SLIDING GATES AND USE THE SCALE TO GET AN APPROXIMATE SET
POINT. ALIGN THE EDGE OF THE DRIVE ANGLE WITH THE SCALE USING 1/2 THE WIDTH OF
THE BOX AS THE PARAMETER.
EXAMPLE: IF THE CASE YOU ARE RUNNING IS 10" WIDE, YOU WOULD ALIGN THE EDGE
WITH 5” ON THE SCALE. TO CHECK, PUT A FULLY FORMED CARTON INTO THE
DRIVE SECTION AT DISCHARGE END. THERE SHOULD BE APPROXIMATELY
1/8” CLEARANCE ON EACH SIDE OF CARTON.
8. TOP SLED ADJUSTMENT:
SET POINT: HEIGHT OF ERECTED BOX + 1/16”
TO SET, PUT A FULLY FORMED CARTON INTO THE DRIVE SECTION AT THE DISCHARGE
END. USE THE CRANK HANDLE LOCATED NEAR THE OPERATOR’S STATION TO RAISE OR
LOWER THE SLED UNTIL IT CONTACTS THE TOP OF THE BOX FLAPS. THE BOX SHOULD HAVE

LIGHT PRESSURE ON IT, NOT BINDING. ALIGN THE SCALE TO THE TOP OF THE BRACKET AT
A MEASUREMENT EQUAL TO THE HEIGHT OF THE BOX PLUS 1/2 THE WIDTH
(IN INCHES).
OTHER SET-UP CONSIDERATIONS:
WHEN HANDLING SMALL CASES, ONLY TWO VACUUM CUPS WILL BE REQUIRED.
REMOVE ONE OF THE VACUUM CUP BARS ALONG WITH THE VACUUM CUPS.
DISCONNECT THE TWO HOSES USING THE QUICK RELEASE FITTINGS WHICH WILL
AUTOMATICALLY SEAL OFF THE VACUUM SYSTEM.
WHEN RUNNING A TALL BOX, USE THE VACUUM POST EXTENSION SO THE CUPS WILL
REACH THE UPPER CORNERS OF THE MAJOR PANEL.
TWO SETS OF FLAP FOLDING TOOLS ARE PROVIDED. THE SMALLER SET SHOULD BE
USED FOR BOXES UP TO 12” IN LENGTH. THE LARGER SET SHOULD BE USED FOR
BOXES LONGER THAN 12” IN LENGTH.
TWO PUSHER DISKS ARE PROVIDED. THE SMALLER DISK SHOULD BE USED FOR BOXES
UP TO 8” IN WIDTH. THE LARGER DISK SHOULD BE USED FOR BOXES OVER 8” WIDE.
THE FORMING BAR, (ALONG WITH THE FINGERS) HELPS OPEN THE BLANK AS IT IS
PULLED INTO THE FORMING AREA. IT SHOULD STRIKE THE CENTER OF THE MINOR
PANEL AND CAUSE A GRADUAL OPENING. IT IS ADJUSTABLE IN TWO DIRECTIONS,
TOWARD THE HOPPER AND TOWARD THE LUG DRIVE. FOR MOST BOXES, NO
ADJUSTMENT WILL BE NECESSARY. IF YOU ARE HAVING DIFFICULTY OPENING A BOX,
YOU CAN TRY ADJUSTING HOW SOON AND WHERE THE BAR STRIKES THE MINOR
PANEL. MOST BOXES (PROVIDED THEY MEET THE CORRUGATED SPEC), WILL RUN
SATISFACTORILY BY ADJUSTING THE FINGER DEPTH AND FORMING BAR POSITION.
IMPORTANT!!!!!: MAKE SURE TO TIGHTEN ALL FASTENERS AFTER CHANGING
TOOLS OR MAKING ADJUSTMENTS BEFORE STARTING MACHINE.
