摘要:
Disclosed is a method for producing dosing molds, according to which two separating films (7) are contacted with each other in a defined area, an active substance-containing melt is introduced between the separating films (7) such that a pocket for receiving a portion of the melt is embodied in at least one of the separating films, and the separating films (7) are separated from each other in order to eject the portion. Preferably, a method is disclosed in which the separating films (7) are contacted with each other in the gap of two molding rolls (2, 3) which rotate in opposite directions and are provided with opposite recesses (4, 5) on the surface thereof, and into which the separating films (7) can be pressed when the active substance-containing melt is introduced so as to form pockets. The separating films (7) make it possible to avoid a direct contact between the melt and the rolls (4,5) and thus prevent the melt from adhering to the roll (2, 3). Elastically deformable separating films (7) support the ejection process as a result of the stress thereof being released after leaving the roll gap (2, 3).
