MACHINE TERMS
PEEL EDGE:
The peel edge is the beveled plate located at the end of the applicator nose. When the label liner is pulled
around the peel edge, the label separates from the liner and is transferred to the vacuum grid, tamp pad, or
product depending on the applicator type.
PEEL EDGE LABEL TENSION SPRING:
This tension spring is attached to the bottom of the spring block assembly. It is used to keep the label liner
flat on the peel edge surface and assist in controlling the dispensing of the label onto the vacuum grid, tamp
pad, or product. The tension is adjustable to accommodate varying label thickness and release properties.
REWIND MANDREL / SLIP CLUTCH:
The rewind mandrel is provided to store the label liner after labels have been removed. It is equipped with
a slip clutch and is driven by the stepper motor. The pressure exerted by the slip clutch is adjustable.
UNWIND ASSEMBLY:
The roll of labels is placed on the unwind assembly for dispensing onto the product. The unwind block is
used to mount the unwind assembly to the main module. The unwind assembly can be removed and
remounted on the opposite side of the module for easy conversion from a right-hand to a left-hand
applicator or vice versa.
UNWIND ROLL MANDREL:
The unwind roll mandrel is equipped with an adjustable spring tension disk, a brake, and a quick-change
outer disc. The unwind roll mandrel and the dancer arm maintain proper web tension and prevent
excessive run-out of the label liner as labels are processed through the machine.
VALVE BANK:
The valve bank will consist of single valve for a merge applicator with an imprinter, two valves for a blow
box applicator, or three valves for a tamp applicator. The valve bank has built in regulators and gauges and
plugs into the valve connector on the rear panel.
WEB PATH:
The web path is the path the label liner follows from the unwind assembly through the various rollers to the
applicator nose.
