The Roving Carder is made of laminated birch and has a hard white coating. The drums of the Roving Carder is (10 cm (4") wide). In order to ensure a long life, the teeth on all Louët carders are made of high grade plated steel wire. All gearboxes, except for the Elite drumcarder, are enclosed to prevent fibers entering the gear system.
The Roving Carder has an extra fine cloth (72 teeth per square inch). The advantage of this extra fine cloth is that you also can perfectly card very fine fibers.
All drumcarders are equipped with a doffer brush, doffer pin and two table clamps to clamp it onto a sturdy table. An instruction manual written by well known author and fiber artist Deb Menz is included with all drumcarders.
For drumcarders it is common to mention the gear ratio that drives the licker-in when you rotate the large drum. For the Roving carder the ratio is 3.8:1. However, what really counts for carding is the ratio of the surface speed of both drums. You get this by multiplying the gear ratio with the ratio of the diameters of the large drum and the licker-in. This surface speed ratio is 12:1 for the Roving Carder.
