Abstract
A threshing unit for combine harvesters has a cylinder, an assigned concave, at least one drum situated downstream of the cylinder, redirecting a threshed crop material out of a threshing region, and conveying it further in a direction of a remaining-grain separating device, wherein threshing slats of the cylinder and slats of at least one downstream drum are situated at a distance from one another in a circumferential region of the cylinder, and wherein peripheral speeds of the cylinder and the drum are synchronized with one another such that in a turning and scraping region the slats of the cylinder and the drum are always positioned opposite each other, or in a leading position that slightly deviates from the position opposite each other, or in a trailing position which slightly deviates from the position opposite each other.
