    • 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).
    • 公开了一种用于生产定量给料模具的方法,根据该方法,两个分离膜(7)在限定的区域中彼此接触,含活性物质的熔体被引入到分离膜(7)之间,使得用于接收 熔体的一部分体现在至少一个分离膜中,并且分离膜(7)彼此分离以便喷射该部分。 优选地,公开了一种方法,其中分离膜(7)在沿相反方向旋转的两个成型辊(2,3)的间隙中彼此接触并且在表面上设置有相对的凹部(4,5) 并且当引入含活性物质的熔体以形成袋时,分离膜(7)可以被压入其中。 分离膜(7)使得可以避免熔体与辊(4,5)之间的直接接触,从而防止熔体粘附到辊(2,3)上。 弹性变形分离膜(7)由于在离开辊间隙(2,3)之后其应力释放而支持喷射过程。
