Abstract: A device for grouping and/or separating of articles which are transported on a conveyor device (10) along a conveying plane in at least a row in an essentially closed stream and which are grouped by at least one separating finger (16) which is inserted into the stream from below, transverse to the conveying direction (t). The separating finger (16) is inserted in the stream in such a way that a targeted article and the articles following the targeted article are slightly delayed or accelerated during their forward movement in the conveying direction (t) whereby a gap is formed. The separating finger (16) engages with a lateral edge of an outer surface of the article includes a contact area (26) that at least partially contacts and/or at least partially encompasses the outer surface of the article.

Abstract: A grinding wheel includes a carrier wheel and a grinding layer formed on a peripheral surface of the carrier wheel. The grinding layer includes grinding segments and cup-shaped or scoop-shaped openings between the grinding segments.

Abstract: Grinding tool for the machining of particularly brittle materials, whose abrasive rim bond is constructed of two components, whereby one component consists of resinoid such as, for example, high temperature thermoplast or pressure sintered polymer and a second component of low melting sintered metal. The processing temperature of both components by the joint pressure sintering is the same. The nature of the invention consists in the construction of a particular connected network for each of the two different bonding agents and their interrelated spatial intertwining in the abrasive rim to an interpenetrating network. A process for the production of abrasive rims for grinding tools according to the invention is indicated.
