Merritt MX Series
This versatile extruder is engineered for high throughput rates and lower mel t temperatures for a
range of applications.
EXTRUSION LINE COMPONENTS
Extrusion lines can be built with a wide range o f extruders, payoffs and tension brakes, take-ups
and auxiliary equipment including cooling troughs, capstans and accumulator systems. Laboratory
equipment, customized feedscrews, and control systems are also available.
C O MPLETE EXTR U SIO N SYSTEMS
We supply complete wire and cable extrusion systems for commun ication, construction/building ,
telephone, and automotive wire, high temperature wire, plug, optical fiber and s pecialty wire.
Capabilities include communication cable systems, automotive cable systems, power cable
systems, construction cable s ystems , fiber optic systems and coaxial cable systems. All wire and
cable extrusion s ystems are available with Clipper take-ups, payoffs and spoolers, customized
feedscrews and patented micro-processor based control systems.
WIRE HANDLING EQUIPMENT
We offer high performance wire handling equipment including capstans, payoffs and take-ups, and
linear caterpillars.
Capstans
Belt wrap capstans are available from 6 to 84 inches (150 to 2,133mm) in diameter, dual wheel
multi-pass configurations from 12 to 32 inches (300 to 813mm) in diameter, with lengths to 40 feet
(12 meters) in dry and wet arrangements. Linear caps tans (caterpillar) from 14 to 80 inches.
Payoffs and Take-Ups
Davis-Standard, LLC offers a com plete range of payoff and take-up systems designed to handle
products as small as 40 awg soft copper and as large as jacketed cable to 6 inches in diameter.
The payoff product offering includes flyer type, sing le and dual, in s izes from 24-inch to 50 -inch with
accompanying lift trucks and tension brake assemblies.
Single reel payoffs, both motorized and drag type, and s ingle reel take-ups in various configurations
including rol l-thru, retracting arm sha ftless and shaft type, with ranges from 12-inch to 120-inchflange diam eters with weight capacities to 40,000 pounds . For precise control, a complete line of
oscillating des igns is available.
Dual reel fully automatic take-ups range in size from 6 to 50 inch and include both shaft types for
speeds to 5,000 fpm and s haftless des igns running at speeds to 9,500 fpm.
Single reel, dual reel, flyer, and portal pay-offs and take-ups for a wide range of app lications.
Options are available for portal, cantilevered arm, and floor traversing.
Specialty Equipment
Equipment is available for fiber optic cable lines , CATV cable lines , high temperature wire lines , and
silicone rubber lines.
Auxiliary Equipment
Auxilia ry equipment includ ing coo ling troughs , capstans, semi-automatic and ful ly-automaticspoolers, caterpillars, wire pre-heaters, and curing systems can be supplied based on application.
C O N TIN UO U S VU LC A N IZA TIO N (C V) SYSTEMS
Radiant Heat Gas Cure System
This s ystem provides a fast and econom ical dry cure for thermoset ins ulations, particularly XLPE. By
utilizing nitrogen as the curing media, the presence of moisture is el imina ted during the critical
curing process . A patented by-product removal system that removes contaminates and increases
the efficiency of the radiant curing s ystem by circulating the nitrogen continuously is optionally
available.
Cure system componen ts are manufactured to quality specifications for press ure
vessels and fabricated stainless steel.

Complete s ystem includes an in-tube, no-contact sag control, variable water level and
pump controls, primary seal and lead wire seals.
The heated tube is divided into separately controlled heat zones, which a re
independently adjus table to 842F (450C).
Heating elements are calrods uniquely designed for extended life.
Each zone is equipped with blowers to circulate air through the chamber around the
calrods for fast cooling during shutdown.
System can be utilized as a gas /water system for low and m edium voltage, gas/gas
system for high and extra-high voltage, and as a steam/super-steam s ystem for rubber
products.
Can be retrofitted to an existing continuous vulcanization line .
Steam Cure System
These systems are best suited for minimum investment cost, and for extrusion compounds not
formulated for high temperature curing. A variety of configurations o f steam C V processing are
available. Steam bo ilers provide fast pressure ris e in the cure tube at start-up.
Steam cure s ystems provide broad flexibility in operation.
Water level controls permit accurate control of steam-to-water ratios for optim um cure
conditions on every cable cons truction.
This equipm ent processes rubber, XLPE, and regular thermoplas tic polyethylene
without changing a major piece of equipment.
Power cables from utility through transmis sion voltage may be produced over a very
broad speed range.
