Abstract
An apparatus for supplying flat, disc-like articles, such as pharmaceutical compacts and similarly configured technical small parts, in particular tablets (1), and for sealing the articles in hot-sealing sheet (5, 105) comprises a conveyor for supplying the articles and two hot-sealing rollers (30, 130), one of which is arranged on either side of a conveying path (3). A hot-sealing sheet (5, 105), is supplied from each roller so that the rollers receive the articles in seal wells (32, 132) between the hot-sealing sheets and seal the articles between the sheets. A finger roller (10) for positioning the articles is arranged on the conveying path (3) in front of the hot-sealing rollers (30, 130). Between the finger roller (10) and the hot-sealing rollers (30, 130) on both sides of the conveying path (3) there is a respective polygonal roller (20, 120) for geometrical constrained guiding and separating of the articles. The cross-section of the polygonal rollers (20, 120) can have the form of a triangle which is rounded at the corners ( 26, 126) and at the side faces. The axes of all the rollers lie parallel to each other and parallel to the conveying plane but at right angles to the co…
