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 conveying path (3). The finger roller (10), the polygonal rollers (20, 120) and the hot-sealing rollers (30, 130) are arranged in series in such a manner that the supplying, positioning, separating, sealing and carrying away of the articles take place in a horizontal plane.
