Part and Instruction Manual
Loveshaw Pressure Sensitive Taping Machine
Semi – Automatic - Uniform
Model: LD7D/3

2
Theory of Operation:
The LD7 with the Loveshaw patented design tape cartridges apply pressure
sensitive tape to the top and bottom center seam of regular slotted containers.
The standard model machine applies the tape in a “C” clip configuration. The
LD7 is manually adjustable in width and height to accommodate a large range of
boxes.
Starting the machine is accomplished by switching on the manual motor starter.
The manual motor starter is a toggle design with an integral overload heater to
protect the drive motor. By switching, the motor starter to it’s “on” position the
dual bottom belts will begin to move. The drive belts are high quality rubber
rough top belting. With the box height and width adjustments, set the machine
is ready for operation. The operator presents the box to the machine will all
flaps folded and held down. The box is then move to the entrance of the machine
and the dual bottom drive belts pull it forward towards the tape cartridges. As
the box reaches the tape cartridges optional top flap squeezers push the major
flaps together prior to tape being applied. This insures a quality-sealed box will
exit the machine. After tape is applied to the top and bottom of the box, it will
exit the machine. A minimum distance of 14” is required between boxes for the
machine to operate properly.
The simple but sophisticated design insures a minimum of maintenance
problems and the machine is easily operated by general labor with minimum
training. Due to its small size and simple electrical connection, it can be moved
quickly to an area where it is needed. It can also be used for standalone
operation, or incorporated into a conveyor system.
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 please contact our service department.

Installation:
For domestic customer only – The Little David is shipped completely assembled.
The Little David is ready for operation after plugging it into an appropiately
grounded electrical outlet. The line cord is located on the operator side of the
machine.
The conveyor height of the machine can be manually adjusted from 22 ¼” to
30 ¼ “ in one inch increments. The exstension legs have a series of holes that
allow for different heights depending on which holes are selected. There are
mounting holes located in the bottom of the leg exstension to anchor the
machine to the floor. It is important that the machine be located on a flat level
surface; so that it does not rock. Optional caster are available to aid in moving
the machine from one location to another as needed.
The machine can be fed either by a conveyor or a packing table. It is important
that either the conveyor or the table be ¼” lower than the tops of the rough top
belting. This makes for the easiest transition into the machine. It is
recommended that a power conveyor be used at the discharge end of the
machine to take away sealed containers.
An optional packing table can be mounted on either the infeed, exit or both ends
of the machine. Refer to figure 1 for an overall view of the machine.

Operation:
With the tape cartridges loaded and installed in the machine it is ready to be set
up. Place a sample box with all of its flaps folded at the infeed of the machine.
Loosen the side rails locking knob by turning counter clockwise and adjust the
rails to the width of the box. Move the rails by hand until the desired width
adjustment is made. And then turn the locking knob clockwise until the rails are
locked in position. Now loosen the upper taping head assembly lock knob. The
lock knob is located on the side of the head assembly near the mast assembly.
With the lock knob loosened the head can be moved up or down by pushing or
pulling on the head assembly. Now take the sample box and move it under the
entrance of the head assembly. Push down on the head assembly until the box
hold down rails firmly contact the top of the box and fully pushes the top box
flaps down. Lock the head assembly in position by turning the locking knob
clockwise. The head assembly is balanced by a constant force spring which
makes head height adjustments easy.
Test the box set up by turning on the machine. This is accomplished by lifting
the toggle switch on the motor starter. Place the sample box at the infeed of the
machine and while holding the top flaps down push it into the machine onto the
rough top belts. The box should come out of the discharge end of the machine
sealed with tape.
If the box hesitates going through the machine it matybe necessary to check the
head height adjustment made previously. It is important to have enough hold
down force on the rough top belts to make sure that the boxes will travel
smoothly through the machine.

Machine components:
Starter Switch:
The starter switch is mounted on the operator side of the machine. The
device is a manual motor starter with integral overload protection. The
device starts and stops the drive motor while protecting the motor from
over current conditions such as a box jam. When the motor starter
detects an overload conditon the machine is automatically shut down.
If the motor starter needs to be replaced, incoming electrical power must
first be disconnected. Follow your company’s lock out / tag out
procedures. The front cover must first be removed allowing acess to the
starter itself. The starter is either removed by removing mounting screws
or lifting the starter off of din rail. This depends on the machine voltage
and the type of stater being used. All 120/1/60 VAC and 230/1/60 VAC
models require mounting screws to be removed. These starters also have
a non-adjustable heater element in them which needs to be replaced. The
starters mounted on din rail have a dial adjustable overload relay.

11
Side Rails:
The side rails center and align the box as it is being processed. The side
rails are manually adjustable and are held in position by a manual lock
knob. The side rails should never be used to drag or move the machine.
The side rails can also be used to hold a box in position on the pack table
while being filled.
Belts:
Two laced rough top belts located on the bed frame of the machine drive
the box through the machine. The rough top belts are driven via two drive
rollers at the exit end of the machine. The drive rollers are directly
coupled to a dual output shaft reducer which in turn is connected to the
main drive motor. The drive rollers have lagging attached to the face of
them which increases the drive to the belt surface.
To replace the belts first jog the motor via the motor starter until the
lacing of the belt is on top of bed frame of the machine. Pull the lacing pin
out of the belt to be replaced. Connect one end of the old belt to one end
of the new belt with the lacing pin. Now pull the old belt out of the
machine. This will thread the new belt through the machine. With the new
belt completetly threaded through the machine, disconnect the old belt.
Connect the new belt ends together. The belt is spring tensioned, and the
tensioner has to be overcomed in order to connect the belt ends.

It is recommended that both belts be replaced at the same time. It is
important to replace the belts with genuine Little David belts, since they
are engineered specifically for the application.
Belt finger guard:
The rough top belts have finger guards that prevent the entanglement or
pinch hazards. The finger guard is adjustable and needs to be adjusted as
the rough top beltings rears down. The gap from the guard to the belt
must be set to 1/32”. Failure to set this distance may result in injury.

Head Assembly:
The head assembly rides along the mast via ball bearings and high density
polyethylene pads. The head height is adjust by turning the lock knob
counter clockwise to unlock head travel. The head can be manually
adjusted by simply pushing or pulling the head assembly. The head
assembly is counter balanced by a constant force spring to make head
travel easy. The high density polyethylene pads are used to adjust the
head assembly level from front to rear. The pads are adjustable via
jacking screws on both sides of the mast. By repositioning the screws the
horizontal positon of the head can be adjusted. The mast requires routine
cleaning and lubrication to insure easy movement. Wipe the mast with a
clean cloth and then spray it down with silicone lubricant.

Drive Motor:
The standard drive motor is 1/3 hp open drip proof motor. The motor is
dual rated at 120 or 230 vac single phase 60hz. The motor is open drip
proof design. The motor is coupled to a dual output sealed gear box. The
gear box requires no maintenace.

Top Flap Squeezer:
The top flap squeezers are used to butt the major flaps together before
tape is applied. The squeezers are independantly set to the width of the
box. The squeezers can help close boxes that are not severly overstuffed
with product.
The squeezers are adjusted by loosening the wing nut and sliding the
individual squezer in or out. Caution must be observed not to adjust the
squeezer wheel to far into the path of the box being processed. This will
cause box jams and may damged the box and/or product.
