On the Improvement of Statistical Static Timing Analysis.

A carding flat arrangement for cards in which lateral end head sections are guided along sliding guide members. The center section is made of a material of low specific gravity, and the end head section can be pressed against the sliding guide. The end head sections, furthermore, are provided with sliding surfaces of wear-resistant material of substantially high specific gravity. The center section may be made of aluminum, and be in the form of a hollow section. Reinforced fiberglass may also be used for the center section, and stabilizing elements may be inserted therein. The end head sections may be connected to the stabilizing elements, and the sliding surfaces of the end head sections may be coated with a friction-reducing material. A pressure element is applied to press against the rear side of the carding flat arrangement and/or against the end head sections.
