Cleaning card for e.g. data carrier card reader`s reading head, has section flock attached to carrier unit by ultrasonic-welding, where flock layer of flock includes cleaning fibers that are dimensioned in length, refinement and profile

摘要

The card has a section flock that is attached to a card-shaped carrier unit (1) using ultrasonic-welding in such a manner that clear risings with flat points are formed. The section flock is made of an electrostatically flocked flexible foam material (2). A flock layer of the section flock includes cleaning fibers (3) that are dimensioned in length, refinement and profile and made of polyamide.
