1.1 Description
The Buskro BK731 Labeler is designed to apply pressure-sensitive labels onto mail
pieces. The system offers full flexibility in its ability to apply labels onto mail pieces.
Simplified mechanical adjustments and software controlled label placement functions
offer unsurpassed ease of use permitting rapid job setups.
In keeping with Buskro’s philosophy of ease of use, the Labeling head is designed with
many innovative features. The Labeling head is controlled through software via an
operator keypad that permits rapid selection of the number of labels dispensed and their
placement positions. A unique label-sensing feature allows the operator to easily adjust
the label pitch at a touch of a button. The Labeling head mechanism was designed with
few mechanical parts to allow easy label threading and machine setup to improve
productivity. The Labeling head is mounted on two aluminum extrusion rails, which
allow the Labeling head to be moved easily from side to side to allow labels to be placed
at different locations on the mail piece and facilitate fine tune adjustment. In addition, the
peel point assembly can be adjusted up, down, and laterally for different material
thicknesses and label widths.
All these features, in addition to the manufacturing quality and innovative product design
add up to an extremely functional labeling system capable of years of reliable and trouble
free operation.
1.2 Features
1.2.1 High Speed Production
The BK731 Labeling head is capable of high production speeds in excess of 35,000 PPH
for single label operation, 30,000 PPH for double label operation, and 28,000 PPH for
triple label operation. The unit has been solidly constructed with electrical components
capable of delivering reliable, full-day production.

1.2.2 Simplified Mechanical Adjustments
The BK731 Labeling head is design for ease of use and portability. The operator keypad
is easily accessible simply by sliding it in and out of view. The BK731 Labeler is
mounted on two aluminum extrusion rails, which allow easy movement of the Labeling
head to place labels at different locations on the mail piece and facilitate fine adjustment
of label placement on the product. The peel point can also be adjusted up, down, and
laterally for different product thicknesses and width. Label threading is easy since the
Labeler has few rollers and a large label bin. In addition, the despool roller is not
controlled by a motor but a simple adjustment knob thus reducing the cost of repair. The
Labeler is also fully portable as all the electronics are located inside the unit.
1.2.3 Software Controlled Labeler Head Functions
All Labeling head functions are controlled through software and use an operator keypad
interface for command entry. A unique feature is the automatic label pitch setting, which
allows the operator to set the distance between each label on the backing paper at a touch
of a button. Other features include type of labels, position of labels, full labeling head
diagnostics, product sensor selection, peel point sensor sensitivity adjustment and
production and life counters.
1.2.4 Construction, Safety Features, and Maintenance
All mechanical and electrical system components in the Labeler have been designed for
long-lasting and extensive use. Included is a full safety package with feedback through
the operator display, monitored by a series of interlocking sensors. The Labeling head
operator interface is easily accessible with a simple slide rail design on the Labeling head.
