Device for sealing capsules

An apparatus (22) for sealing capsules (10), wherein the capsules (10) have a respective capsule shell, which is formed by a first shell part (12) and a second shell part (14), wherein the shell parts (12, 14) are provided or have been provided with a banding liquid (20) in a connecting region (16), wherein the apparatus (22) comprises the capsules (10) and a heat source (30) for drying the banding liquid (20), wherein the apparatus (22) has at least one screen (32), which is arranged in a radiation region of the heat source (30) between the heat source (30) and the capsules (10), wherein the screen (32) has at least one elongate opening (34) having a length dimension that is longer than a width dimension (40) and being positioned such that radiation from the heat source (30) to the capsules (10) irradiates the connecting regions (16) of the capsules (10), wherein the screen (32) has at least one shielding region (36), and wherein the screen (32) is arranged such that the length dimension of the at least one elongate opening (34) extends parallel to a transport direction (26) of the capsules (10), and

• wherein the capsules (10) are positioned such that the connecting region (16) of the capsules (10) passes under, relative to the heat source (30), the at least one elongate opening (34) while partial regions of the capsules (10) that are arranged offset from the connecting region (16) are shielded against radiation from the heat source (30) by the shielding region (36), the connecting region of the capsules having a length dimension measured parallel to a capsule axis, the width dimension of the at least one elongate opening matching the length dimension of the connecting region, and the screen and the capsules transported in the transport direction are spaced, such that, with respect to the capsule capsules (10), the radiation from the heat source (30) is input exclusively onto the banding liquid (20).
