System requirements
Compressed air Compressed air connection with 4-6 bar must be available. If the pressure is higher, a
pressure reducer must be installed (available as accessory, article no. A9398).

• Installed applicator interface (optional) with firmware version 1.03 or higher. If the
applicator interface was retrofittet, pay attention that the D-Sub 15 connector for
Avery applicators (top side of the front hood) is available.

Functionality
The LTP/LTPV applicator is an additional module to be mounted to one of the above
named label dispensers or print & apply machines (see chapter Intended Use of Sys-
tem on page 2). The device takes over self-adhesive labels from the dispensing
edge of the dispenser/print & apply machine, moves each of the labels to the product
in a linear movement and attaches it to the product.
The label is held by a pressure plate that is driven by a pneumatic cylinder between
home position and end position.
In home position, the label is taken over from the dispenser or the print & apply
machine. The arrival of the pressure plate in home position is detected by a sensor at
the pneumatic cylinder of the applicator. The label is peeled off the backing paper by
the dispensing edge and is pushed under the pressure plate, where it is sucked on by
a vacuum. Additionally, the label is blown onto the pressure plate by an air stream from
the support air nozzle. Afterwards, the pressure plate moves to the end position, whe-
re the label is attached to the product.
The arrival in the end position is detected by 4 sensors which are integrated in the
pressure plate. The sensors are activated, as soon as the pressure plate presses
slightly against the product. This „light touch“ function enables the LTP/LTPV to label
products with varying heights and especially sensitive products.
