The Deltaformer is a proven high dilution former that has
been used to produce a wide variety of nonwovens and specialty paper
sheets. When using inorganic or organic fibers with long fiber lengths,
large volumes of water must be used to disperse the fibers and to
keep them from entangling with each other.
The Deltaformer is designed to handle long fiber stocks that
have to be formed at low consistencies such as nylon, dacron, rayon,
orlon, cotton, polypropylene, fiberglass, and abaca.
The Deltaformer design features allow for high hydraulic
drainage capacities needed to produce a variety of durable and disposable
nonwovens from roofing mat to filter membranes, specialty paper
grades to refractory materials.
The stock inlet system is custom designed for each application,
using CFD modeling, to ensure an even flow distribution across the
headbox resulting in a uniform basis weight profile of the sheet.
The Deltaformer features a vacuum forming box with multiple
compartments, each equipped with an individual system for flow and
vacuum control. This permits controlled drainage for the best formation
and control of sheet properties.
The wire section of the Deltaformer can be cantilevered for
easy fabric changing. The wire incline can be fixed in the optimum
position for your application, or you may choose an adjustable incline
of 15° to 35°. The adjustable angle gives greater flexibility
to control formation and sheet squareness particularly for highly
diluted stocks running at slow speeds.
