A process for the removal of particles (15) that are adhering to dry surfaces (2) of an object to be cleaned is carried out by means of a wiping element (5) in such a way that this wiping element (5) and the surface (2) to be cleaned carry out a movement relative to each other, and in conjunction with this, the wiping element (5) frictionally contacts the surface (2). In order that the particles (15) that are adhering to the surface (2) can be easily picked up by the wiping element (5), the wiping element (5) is moistened to such a slight extent that the particles (15) adhere better to this wiping element than to a dry wiping element, whereby, however, this amount of moisture is so chosen that the contacted surface (2) to be cleaned itself remains dry, so that the adhesive forces there would not in turn be increased by the cleaning liquid.
A process for the removal of particles (15) adhering to a dry surface (2) by means of contacting said dry surface with a wiping element (5), comprising moistening a surface of the wiping element (5) with a moistening liquid thereby forming a wiping element having a moist surface (5), wherein said moistening is to such a slight extent that the dry surface (2) to be contacted by the moist wiping element (5) will remain dry when contacted by the moist wiping element, effecting a relative movement a selected speed between the dry surface (2) to be contacted and the moist wiping element (5) such that the moist surface of the wiping element (5) is moved transversely to a direction of forward feed of the dry surface (2) to be contacted and frictionally contacts the dry surface (2) thereby removing the particles from the dry surface, measuring moistness on the moist surface of the wiping element (5), applying additional moistening liquid on a regulated basis in response to said measurement of the moistness on the surface of the moist wiping element (5), and applying the additional moistening liquid to the moist wiping element (5) to maintain a desired level of moisture on the moist surface of the wiping element (5).
A process for removal of particles (15) adhered to a dry surface to be contacted (2) by means of a moistened wiping element (5) having a moist surface comprising moistening a surface of a wiping element (5) with a moistening liquid thereby forming a wiping element having a moist surface, whereby said moistening is to such a slight extent that the dry surface (2) to be contacted by the moistened wiping element (5) will remain dry when contacted by the moistened wiping element, effecting a relative movement at a selected speed between the dry surface (2) to be contacted and the moistened wiping element (5) such that the surface of the moistened wiping element (5) is moved transversely to a direction of forward feed of the dry surface (2) to be contacted, and said moist surface of said moistened wiping element frictionally contacts the dry surface (2) to be contacted to thereby remove the particles (15) from the dry surface, determining an amount of the moistening liquid to be applied to the surface of the wiping element based on the speed of relative movement between the moistened wiping element (5) and the dry surface (2) to be contacted such that the moistening liquid wets fibers or bristles (13) of the wiping element (5) in the form of a film (14) and the dry surface (2) contacted by the moistened wiping element (5) remains dry.
