Parallelizing action is often attributed to the card. This is not completely justified, since the fibers in the web are not parallel, although they do have, for the first time, a certain degree of longitudinal order. It is true that a parallel condition is achieved on the 
main cylinder, but it disappears during formation of the web between the cylinder and the doffer. Thus, the card can be given the task of creating partial longitudinal orientation of the fibers, but not that of creating parallelization.
