Step 5 - FILTER
PRESS CLOTH CONSTRUCTION
Construction of filter cloth assemblies
plays an equally important role to the fabric design in achieving
optimum performance. A precise fit assures peak performance.
Methods of Attachment
There are various methods for fastening cloth. Attachments may be
stitched, welded or machine assembled to provide durable constructions.
Peg eyelets, cloth castellation & rod suspension are used to carry
the cake weight. Side tie eyelets & reinforced holes, keep the
cloth flat and positioned correctly.
Velcro
Velcro provides a lapping joint, which has superior strength and keeps
the cloth aligned correctly throughout the many months of operational
life. This attachment is easily repositioned or released for plate
inspection or adjustment.
Edge
Reinforcing(Banding)
Reinforcing around the filter plate sealing surface and over the stay
bosses will increase the mechanical strength of the cloth. Micronics
banding material is specifically manufactured with high tensile strength
and stability for this application.
CLOTH NECK TYPES
High
Performance Rubber (HPR)
The Micronics patented design uses thermoplastic
rubber compounds and a controlled temperature welding system to attach
the feed neck to polypropylene filter cloth. This 100% impervious
joint guarantees filtration only takes place within the filter chamber.

Plastic
Neck (SK)
This new patented product allows rigid, polypropylene, Nylon or Polyester
necks to be attached to any fiber type. The benefits of performance
are the same as the HPR design but it also allows other fibers to
use an impervious design.
Rubber
Coated Neck
For applications where cloth attachments are desired a coated neck
should be selected. This product uses synthetic rubber formulations
determined by Micronics to be abrasion
resistant and chemically stable. They will always outperform hand
applied treatments.
