The card comprises a large number of individual parts that guide the material, open it and clean it. Optimal, gentle treatment is only possible if these parts have the correct form and the right relative positions and spacings. The socalled settings of the card are of the greatest importance. For example, too narrow spacing of the operating elements leads to fiber damage (loss of breaking strength); too wide a setting produces more neps.

 Table of settings shows the most common settings for conventional cards. The  licker-in on these conventional cards calls for special treatment: the licker-in has to be removed and replaced by a gauge in the form of a pendulum (Fig. 147). The radius of the gauge has to correspond exactly to that of the licker-in. It should be realized that the settings vary from one make of machine to another – the setting instructions of the individual manufacturer must be followed. This applies especially to modern, high-performance cards. That is why no instructions for these cards can be given here.
