BELT LAGGING INSTALLATION
1. IF THE BELT MOVES TO THE LEFT OR RIGHT AT THE EXIT END OF THE MACHINE,
THEN THE BELT LAGGING (FRICTION) MATERIAL ON THE DRIVE ROLLER MUST BE
CUT ON THE SAME SIDE THAT THE BELT IS MOVING TOWARDS. TO ACCOMPLISH
THIS, FIRST REMOVE THE BELT THAT IS MOVING OUT OF LINE AS DESCRIBED
ABOVE, SO THAT THE EXIT ROLLER CAN TURN FREELY, AFTER THE MACHINE
IS TURNED ON.
2. TURN ON MACHINE AND WITH A UTILITY KNIFE, CUT ABOUT 1/8” OFF THE BELT
LAGGING MATERIAL BY PLACING THE POINT OF THE KNIFE ON THE LAGGING
MATERIAL WHILE THE DRIVE ROLLER ID TURNING. BE SURE TO PLACE THE
KNIFE ON THE ROLLER SO THAT THE ROLLER IS MOVING AWAY FROM THE POINT
OF THE KNIFE.
3. AFTER A COMPLETE CUT IS MADE, TURN MACHINE OFF AND WITH THE POINT OF
THE KNIFE, LIFT UP A SECTION OF THE CUT LAGGING AND PULL OFF UNTIL IT IS
REMOVED FROM THE DRIVE ROLLER COMPLETELY. (THIS CAN BE DOME BY
JOGGING THE MACHINE ON/OFF WHILE PULLING THE CUT STRIP OF LAGGING).
4. REPLACE BELT AND CHECK ALIGNMENT. BELT WILL HAVE MOVED TO THE
OPPOSITE SIDE THAT WAS CUT. THIS PROCEDURE MAY HAVE TO BE REPEATED
UNTIL THE BELTS ARE CENTERED.

INTRODUCTION
THE LITTLE DAVID LD7D UNIFORM PRESSURE SENSITIVE TAPER IS DESIGNED TO TAPE THE TOP AND
BOTTOM FLAPS OF A WIDE VARIETY OF BOX SIZES. AFTER MANUALLY ADJUSTING THE MACHINE
FOR THE BOX SIZE, THE OPERATOR ONLY HAS TO FOLD THE FLAPS AND PUSH THE BOX INTO THE
MACHINE AFTER WHICH THE MACHINE WILL TAPE THE TOP AND BOTTOM FLAPS AND DISCHARGE
THE BOX.
THE SIMPLE BUT SOPHISTICATED DESIGN INSURES A MINIMUM OF MAINTENANCE PROBLEMS AND
THE MACHINE CAN BE EASILY OPERATED BY UNSKILLED OPERATORS. DUE TO ITS SMALL SIZE AND
SIMPLE PLUG-IN CONNECTION, IT CAN BE QUICKLY MOVED TO THE AREA WHERE IT IS NEEDED. IT
MAY STAND ALONE OR IF DESIRED, BE INCORPORATED IN A CONVEYOR SYSTEM. ALL HARDWARE
USED ON THIS MACHINE IS METRIC.
THE FINEST MATERIALS AND WORKMANSHIP HAVE BEEN EMPLOYED TO INSURE SATISFACTION.
IF ADJUSTMENTS OR REPAIRS BECOME NECESSARY YOU WILL FIND SIMPLE INSTRUCTIONS
OUTLINED IN THIS MANUAL. IF A PROBLEM OCCURS WHICH IS NOT COVERED IN THE MANUAL,

HEAD
THE HEAD RIDES ALONG THE MAST ON BEARINGS AND HIGH DENSITY POLYETHYLENE PADS. THE HEAD
HEIGHT IS ADJUSTED BY TURNING THE HEAD LOCK HAND WHEEL COUNTERCLOCKWISE TO RELEASE THE
HEAD. TURNING THE HAND WHEEL CLOCKWISE WILL LOCK THE HEAD IN THE DESIRED POSITION.
BEARINGS:
IF ANY OF THE BEARINGS WHICH RUN AGAINST THE MAST NEED TO BE REPLACED, PROCEED AS FOLLOWS:
- DISCONNECT ELECTRICAL SUPPLY. PLACE A STURDY BOX/BLOCK ON BED OF MACHINE AND LOWER
HEAD ONTO IT.
- REMOVE COVER FROM BACK OF HEAD TO EXPOSE BEARINGS. LOOSEN OUTSIDE NUTS ON
THREADED SHAFT.
- BACK OFF NUTS BETWEEN BEARINGS WHILE TURNING THREADED SHAFT WITH A SCREW DRIVER UNTIL
DEFECTIVE BEARING CAN BE REMOVED.
- REVERSE ABOVE PROCEDURE TO REPLACE BEARING.
- THE FRONT BEARINGS ARE ACCESSIBLE THROUGH THE BOTTOM OF THE HEAD.
WHENEVER THE BEARINGS HAVE BEEN CHANGED, THE CLEARANCE BETWEEN THE HEAD AND THE MAST MUST
BE RE-ALIGNED. THE CLEARANCE BETWEEN THE TEFLON SLIDES AND THE SIDES OF THE MAST SHOULD BE
ADJUSTED TO APPROXIMATELY .020” (.5 mm). THIS SHOULD BE CHECKED THROUGH THE HEADS RANGE OF
TRAVEL TO INSURE THAT THIS CLEARANCE EXISTS AT THE HIGH POINTS OF THE MAST.
THE CLEARANCE BETWEEN THE BEARINGS AND THE FRONT AND REAR SURFACES OF THE MAST SHOULD BE
SUCH THAT THE HEAD MOVES FREELY AND DOES NOT COCK OR SAG. TO ADJUST THE CLEARANCE, PROCEED
AS FOLLOWS:
- REMOVE COVER FROM REAR OF HEAD.
- ADJUST CLEARANCE OF TEFLON SLIDES OF MAST BY LOOSENING LEFT NUT ON THREADED SHAFT
LOCATED ON THE OUTSIDE OF THE HEAD, AND TIGHTEN NUT LOCATED AGAINST INSIDE OR ROLLER
A CORRESPONDING AMOUNT. THIS IS THE EFFECT OF SPREADING OPEN THE SIDES OF THE HEAD.
ADJUST THE FRONT AND REAR THREADED SHAFTS TOGETHER TO KEEP THE TEFLON SLIDES PARALLEL
TO THE MAST. FIRST ADJUST THE UPPER PAIR OF SHAFTS THEN ADJUST THE LOWER PAIR OF SHAFTS.
- MOVE HEAD THROUGH ITS FULL TRAVEL AND CHECK THAT TEFLON SLIDES HAVE PROPER
CLEARANCE AT THE HIGH POINTS.
- NEXT ADJUST THE FORE AND AFT ADJUSTMENT SCREWS. THESE ARE SET SCREWS THAT ARE
LOCATED IN THE FOUR BLOCKS TO WHICH THE HEAD COVER IS MOUNTED. TURNING THEM CLOCKWISE
WILL MOVE THE ADJACENT REAR BEARINGS IN TOWARD THE MAST. THEY SHOULD BE ADJUSTED SO
THAT THE BEARING JUST CLEARS THE MAST. LOOSEN THE FOUR OUTSIDE NUTS OF THE TWO REAR
THREADED SHAFTS BEFORE MAKING THIS ADJUSTMENT SO THAT THE SHAFTS CAN MOVE IN THEIR
OVER-SIZED HOLES. BE SURE TO TIGHTEN THE OUTSIDE NUTS AFTER ADJUSTING. WHEN PROPERLY
ADJUSTED, THE HEAD WILL BE PARALLEL TO THE BED OF THE MACHINE AND WILL NOT COCK ON THE
MAST AND THE BEARINGS SHOULD RUN FREELY.
- MOVE THE HEAD THROUGH ITS FULL TRAVEL AND CHECK THAT THERE IS PROPER CLEARANCE AT
THE HIGH POINTS.
- REPLACE HEAD COVER.

ELECTRICAL SYSTEM
THE ELECTRICAL SYSTEM CONSISTS OF TWO FRACTIONAL HP DRIVE MOTORS AND THE
STARTER SWITCH. THE MOTORS AND FRAME ARE GROUNDED THROUGH THE ELECTRICAL
CONNECTOR.
THE CIRCUIT BREAKER IS FACTORY SET. IF IT TRIPS, IT SHOULD BE RESET AFTER
INSPECTION OF THE ELECTRICAL SYSTEM.
WARNING: THE INSPECTION OF THE ELECTRICAL SYSTEM SHOULD BE DONE BY A
QUALIFIED ELECTRICIAN ONLY!

LOVESHAW an ITW Company
LUBRICATION
ALL MECHANICAL PARTS ON THE LITTLE DAVID ARE PERMANENTLY LUBRICATED AND
SEALED BEARINGS ARE USED THROUGHOUT.
THE REDUCER USES 6 TO 8 OZS. OF SCH634.
THE MAST SHOULD BE CLEANED AND SPRAYED WITH A SILICONE LUBRICANT - THIS
SHOULD BE DONE ON A WEEKLY BASIS TO ENSURE FREE MOVEMENT OF THE HEAD.

TROUBLE SHOOTING
TAPING DIFFICULTIES:
1. TAPE DOES NOT ADHERE WELL TO BOX:
1. CHECK THAT BOX IS NOT WAXY OR OILY.
2. CHECK THAT BOX IS PROPERLY CUT AND SCORED SO THAT THE FLAPS DO NOT
OVERLAP. IF THE TAPE ADHERES TO THE TOP AND BOTTOM BUT NOT TO THE END
PANELS, THE BOX MAY BE SKEWED FORMING A PARALLELOGRAM. IF THIS CONDITION
EXISTS, BRING IT TO THE ATTENTION OF YOUR BOX SUPPLIER.
3. CHECK THE PRESSURE ON THE WIPE DOWN ROLLERS. IF NECESSARY, INCREASE
THE MAIN SPRING PRESSURE.
4. CHECK THAT THE SPRING IS NOT BROKEN.
2. TAPE END STICKS TO ITSELF OR MECHANISM:
1. CHECK THAT THERE IS NOT TOO MUCH DRAG ON THE TAPE CAUSING STRETCHING
AND SNAP BACK AT CUT OFF. REDUCE THE TAPE CORE DRAG SETTING.
2. CHECK THE TAPE THREADING PATH.
3. CHECK FOR DEFECTIVE TAPE ROLL BY PULLING TAPE OFF MANUALLY. THE PULL
SHOULD BE EVEN AND NOT VARY SUDDENLY.
4. CHECK TAPE GUIDE PLATE SETTING AND FREEDOM OF MOVEMENT.
5. CHECK ROLLER FOR BINDING.
3. TAPE BREAKS OR JAMS:
1. CHECK THE TAPE ROLL BY PULLING TAPE OFF MANUALLY. THE PULL SHOULD BE
EVEN AND SHOULD NOT VARY SUDDENLY.
2. CHECK THE TAPE CORE DRAG SETTING.
3 CHECK THE TAPE THREADING PATH.
4. CHECK FOR NICKS IN EDGE OF TAPE ROLL. PULL OFF DAMAGED TAPE.
5. TAPE TENSION SET TOO HIGH.
4. TAPE WRINKLES:
1. CHECK THE TAPE ROLL BY PULLING TAPE OFF MANUALLY. THE PULL SHOULD BE
EVEN AND SHOULD NOT VARY SUDDENLY.
2. CHECK THE PRESSURE OF THE WIPE DOWN ROLLERS. TOO MUCH OR NO PRESSURE
MAY CAUSE WRINKLES. PRESSURE THAT IS TOO GREAT MAY DEPRESS THE FLAPS
CAUSING PROBLEMS. IF NECESSARY, RE-ADJUST THE PRESSURE.
3. CHECK THAT ALL THE ROLLERS TURN FREELY ON THEIR SHAFTS.
4. CHECK THE BOX CONTENTS. PARTIALLY FULL BOXES OR VERY COMPRESSIBLE
CONTENTS MAY ALLOW THE FLAPS TO DEPRESS EXCESSIVELY CAUSING WRINKLES.
5. CHECK THE DRAG OF THE TAPE. TOO MUCH DRAG MAY CAUSE OVERRUNNING OF THE
TAPE ROLL. ADJUST THE TAPE CORE DRAG SETTING.
6. TAPE TENSION SET TOO HIGH.
7. CHECK ROLLER STOP INSIDE CARTRIDGE.
8. CHECK THAT THE TAPE IS PROPERLY THREADED AND THAT TAPE CORE IS
PROPERLY CENTERED.

9. CHECK THE PRESSURE OF THE HEAD AGAINST THE BELTS AND HESITATE AS IT IS
BEING FED THROUGH THE MACHINE. ADJUST THE HEAD HEIGHT.
10. CHECK THAT THE BELTS ARE NOT SLIPPING.
11. CHECK ADJUSTMENT OF THE GUIDE PLATE AND FINGER PLATE.
5. SHORT TAPE TAB ON BOX:
1. CHECK TAPE TENSION.
2. CHECK ROLLERS FOR BINDING.
6. TAPE NOT BEING WIPED ON BOTTOM OF BOX:
THERE ARE LARGE ECCENTRIC STOPS THAT ARE FACTORY SET TO INSURE THAT FRONT
ROLLER ARM CANNOT BE DEPRESSED BELOW BOX HEIGHT. THEY ARE LOCATED INSIDE
CARTRIDGE ON BOTH SIDES. WHEN FULLY DEPRESSED, FRONT WIPE ROLLER SHOULD
PROTRUDE 3/32” ABOVE CARTRIDGE FRAME. IF THIS NEEDS ADJUSTING, ROTATE THE
ECCENTRIC STOPS. USE BOTH STOPS AND MAKE SURE ROLLER ARM CONTACTS FLAT
SURFACES. WHEN PROCESSING BOXES LESS THAN 5” HIGH, THE ECCENTRIC STOPS
MUST BE MOVED TO THE OPPOSITE HOLE IN THE CARTRIDGE FRAME. THE FRONT
ROLLER SHOULD THEN PROTRUDE TO BELT LEVEL.
7. TAPE NOT CUTTING:
1. CHECK KNIFE ARM FOR MECHANICAL BINDING.
2. CHECK THAT KNIFE IS NOT DULL.
3. CHECK SPRINGS ON KNIFE STUDS.
4. CHECK BUSHINGS IN KNIFE STUDS.
5. IF KNIFE STOP BLOCK IS CAUSING FRICTION ON KNIFE STUDS, ROTATE UNTIL FREE.
6. TAPE TENSION IS SET TOO LOW.
8. TAPE NOT CENTERED ON BOX:
1. USE SCREW IN CENTER OF TAPE CORE TO RE-ALIGN.

TAPE CARTRIDGE
TAPE TENSION ROLLER:
THE TAPE TENSION ROLLER MAINTAINS CONSTANT TENSION THROUGHOUT THE LIFE OF THE TAPE
ROLL. IT HAS A ONE-WAY CLUTCH TO PREVENT PULL BACK ON TAPE. TURNING THE NYLOK NUT
CLOCKWISE INCREASES THE TENSION. COUNTERCLOCKWISE DECREASES TENSION. TOO MUCH
TENSION WILL CAUSE PROBLEMS.
WIPE DOWN ROLLERS:
THE RUBBER WIPE DOWN ROLLERS WIPE THE TAPE ONTO THE BOX AS IT PASSES THROUGH THE
MACHINE. THE FRONT ROLLER HAS A ONE-WAY CLUTCH TO PREVENT KICKBACK OF TAPE. THE
PRESSURE EXERTED BY THE ROLLERS IS ADJUSTABLE BY CHANGING THE POSITION OF THE MAIN
SPRING TO A DIFFERENT HOLE ON THE MAIN TIE BAR. THE PRESSURE SHOULD BE SUFFICIENT TO
OBTAIN A GOOD WIPE. TOO MUCH PRESSURE CAN CAUSE PREMATURE WEAR. PRESSURE SHOULD
BE REDUCED WITH UNDER FILL OR COMPRESSIBLE CONTENTS.
TAPE GUIDE PLATE:
THE TAPE IS GUIDED RO THE FRONT ROLLER BY THE GUIDE PLATE. THE FLAT PORTION OF THIS
PLATE MUST BE TANGENT TO THE RUBBER ROLLER FOR PROPER FUNCTION. THIS IS ADJUSTABLE
BY ROTATING THE ECCENTRIC STOP IT BEARS AGAINST. THE TAPE GUIDE PLATE IN CONJUNCTION
WITH THE FINGER PLATE FORMS THE TAPE WHICH ALLOWS IT TO STAND UP. THE TAPE GUIDE PLATE
MOVES AS THE BOX PASSES, TO FORM A CORNER. THIS ENSURES SMOOTH TIGHT TAPE APPLICABLE
TO THE LEADING CORNER OF THE BOX.
FINGER PLATE:
THE FINGER PLATE PRESSES AGAINST THE ADHESIVE SIDE OF THE TAPE AND FORCES THE TAPE
TO TAKE THE SHAPE OF THE TAPE GUIDE PLATE. IT IS IMPORTANT THAT THE FINGERS JUST MAKE
CONTACT WITH THE TAPE GUIDE PLATE, WHEN THERE IS NO TAPE IN CARTRIDGE. IF AN
ADJUSTMENT IS NECESSARY GENTLY BEND THE FINGERS NEAR THE TIPS. ONLY BEND A SMALL
AMOUNT, THEN CHECK. FINGERS MUST CONTACT PLATE. WHEN THE GUIDE PLATE IS MOVED THE
FINGERS SHOULD NOT FOLLOW. NOTE: FINGERS SHOULD BE ABLE TO MOVE 1/8” AWAY FROM
PLATE.
KNIFE ARM:
THE KNIFE ARM IS MOUNTED AT AN ANGLE TO CUT THE TAPE LIKE A SCISSORS. A STUD LOCATED
ON THE MOUNTING BLOCK TO PREVENT INCORRECT REPLACEMENT OF KNIFE. THE KNIFE SHOULD
BE CLEANED PERIODICALLY USING A RAG AND CLEANING FLUID. DO NOT USE A WIRE BRUSH OR
OTHER ABRASIVE DEVICE. THE KNIFE ARM SHOULD BE ADJUSTED SO THAT THE TIPS OF THE KNIFE
ARM ARE 2 1/2” FROM THE CARTRIDGE FRAME. THIS CAN BE ADJUSTED BY LOOSENING THE SMALL
NUT ON THE KNIFE ARM STUD AND ROTATING THE STUD UNTIL THE LARGE NUT CONTACTS THE
BUMPER AT THE DESIRED SETTING. KNIFE ARM TENSION IS CONTROLLED BY THE COMPRESSION
SPRING ON THE STUD. TIGHTEN THE NYLOK NUT FOR GREATER TENSION. ALWAYS POWER DOWN
MACHINE FIRST.
