Description
ITW Dynatec’s APEX High Speed Intermittent Slot Die Applicator is an air-operated hot melt adhesive
applicator assembly with an optional filter manifold. The applicator is used with intermittent pressure
and constant pressure hot melt adhesive supply units (ASUs). APEX models are offered in several
different module configurations.
Each APEX High Speed Slot Die applicator features various combinations of adhesive valve slot die
modules mounted to a single service block. Each module is opened and closed by air pressure.
Springs are used to keep needles closed when no air pressure is supplied to the head. The rate of
adhesive flow from the applicator is determined by the adhesive pressure applied by the ASU’s pump,
shim thickness and the amount of shim opening.
The applicator is heated by replaceable cartridge heating elements which are controlled by an
integrated RTD sensor and electronic control. A single heat zone for the service block and die allows
for only one temperature control point on models less than 390mm. Models longer than 390mm have
two heat zones and control points.
The APEX module(s) is mounted onto either a steel or aluminium service block. A piston inside the
module is pneumatically triggered by a solenoid valve, which allows adhesive to flow through a valve
within the module.
The APEX offers a variety of heated
adhesive supply hose connections
into the service or filter manifolds.
Adhesive flows from the hose into
and through the channels within the
manifold to the module. Air
pressure opens the adhesive valve,
allowing adhesive to flow through
the module’s die assembly when
the valve is open.
In order to minimize response time,
operating air and electrical
connects from the solenoid valves
are made to each individual
module.
These slot die applicators can be
configured for either ITW Dynatec’s
DynaControl controller,
Microprocessor Temperature
Control/ Compu-Vision (MCV),
DynaPlus/ Pro or it can be
configured for a competitive
upgrade.
