Duncan Carders

Duncan Fiber Enterprises Ltd.
Features of Duncan Carders
Rubber feet are used to prevent shifting of the carders, protect surfaces and minimize noise and vibration. OUR CARDERS DO NOT HAVE TO BE CLAMPED DOWN.
Drums are 7" diameter by 8" or 16", long depending on model.
Frame, Legs and Bearing Blocks :
All wood parts are kiln dried hardwood
Drum Size:
Feet:
Drum Construction:
Drums are constructed of solid medium density fiberboard (MDF) with hardwood plywood ends and precision turned to be perfectly round.
Drum Spacing:
Drum spacing is set and maintained by a rotating diagonal stiff-arm attached to the front bearing block and held rigid by a bracket attached to the carder frame. "Micrometer" adjustments of the gap between the large and small drums can be set by alternately loosening and tightening the nuts attaching the arm to the bracket. Once set, the drum spacing cannot change until reset.
Shafts and Cranks:
1/2" Cold rolled steel is used for all shafts, axles and cranks.
Crank Height:
Our carders can be cranked without hitting your knuckles on the table.
Bearings:
Bearings are sintered bronze graphite impregnated "Oilite", press fit and epoxied tight.
Hardware:
All fasteners are high quality zinc plated. Lock nuts are aircraft type "Nylock".
Licker In Drive:
The small drum , "licker-in" is driven by Pyrothane (R) power transmission stretch belts. The belt does not cross or rub. Our 8" models have the drive on the left hand side of the carder. We use this drive on both sides of our 16" carders.
Card Cloth:
The card cloth we use on all models of our carders has 6 ply, rubberized fabric backing with 80 points to the square inch set in diagonal rows.
Batt Doffing:
On our motorized carder models, the large drum is reversed for batt doffing by means of a 9" diameter hand wheel.
In Feed Pan:
In-feed pans are constructed of 22 ga. galvanized sheet metal and are contoured to guide the fibers onto the large drum as they pass under the licker in drum.
Carder Motor:
The gearmotors we use on our electric carders are heavy-duty totally enclosed fan cooled (TEFC), permanently lubricated with heavy gear oil. The gears are hardened steel. Bearings are heavy duty, needle , roller, and thrust bearings in the gearhead and ball bearings on motor. Motors for the U.S. electrical system are wired for 60Hz, 115 Volts. Motors for European and other 50Hz 230 Volt systems are used when required.
Cleaning:
Clearance between the drum ends and frame parts is sufficient to allow the easy use of fingers and cleaning toools to remove fiber that may collect on the drum shafts and bearings. Our machines do not have to be disassembled for proper cleaning.
