The Louët XL carder is a workhorse. With a width of 12 inches, batts of up to approximately 4 ounces (120 grams) can be carded. 72 TPI (teeth per square inch) carding cloth is made of nickel-plated steel wire on a bed of cotton and natural rubber, which gives it a long life.
The frame of the carder is made of water resistant birch plywood with a white HPL top layer. The drums are driven by a closed gear system. As a result, the carder requires very little maintenance and this keeps fiber from getting caught up in the gears.
In carders, as a rule, the acceleration between the drums is stated. For the standard carder it is 4:1. However, more important for the effectiveness of the carder is the difference in surface speed between the large and the small drum. To calculate this, multiply the acceleration by the ratio of the diameters of the two drums. For the standard Carder, this speed ratio is 9:1.
