    摘要： An apparatus for the manufacture of multilayer articles has a plurality of female dies mounted in a rotary disc. A plurality of feeding devices equal in number to the number of layers in the articles to be manufactured is distributed about the rotary disc. Each feeding device admits a quantity of material into the female dies as these travel by. A compressing device is arranged downstream of each feeding device as seen in the direction of movement of the female dies. The compressing devices compress the material admitted into the female dies by the respective feeding devices and also cause the various layers of material to adhere to one another. When the required number of layers has been formed, the resulting article is ejected from the respective female die. One or more of the feeding devices is movable to an inoperative position in which it is unable to feed the female dies. This movement may be effected while the female dies rotate. The purpose of a movable feeding device is to permit the dosing accuracy of another feeding device to be checked. Thus, by moving a feeding device to an inoperative position, it becomes possible to accurately weigh out the dose of material fed to a female die by another feeding device since the material normally fed by the movable feeding devices does not interfere with the weight measurement. Furthermore, movement of a feeding device to an inoperative position enables a dose of material which is to be weighed to be given a second compression with the compressing device downstream of the movable feeding device. This enhances the cohesiveness of the dose to be weighed.

    摘要翻译： 用于制造多层制品的装置具有安装在旋转盘中的多个阴模。 与要制造的制品中的层数相等的多个进给装置围绕旋转盘分布。 每个喂养装置随着这些旅行而承认一定量的材料进入雌性模具。 压缩装置设置在每个进给装置的下游，如从阴模移动的方向看。 压缩装置通过相应的进给装置压缩进入阴模的材料，并且还使各种材料层彼此粘附。 当已经形成所需数量的层时，所得物品从相应的阴模排出。 一个或多个喂食装置可移动到不能喂养雌模的不工作位置。 这种移动可以在阴模旋转时进行。 可移动进给装置的目的是允许检查另一进给装置的计量精度。 因此，通过将进给装置移动到不工作位置，可以通过另一个进给装置精确地称量供给到阴模的材料的剂量，因为通常由可动进给装置馈送的材料不会干扰重量测量。 此外，馈送装置移动到非操作位置使得能够通过压缩装置在可移动馈送装置的下游使待测量的材料的剂量被赋予第二压缩。 这增强了称重剂量的凝聚力。
