摘要： A machine is disclosed which is intended to apply a saw-toothed blade to containers (for example of cardboard) which hold a coil or roller of aluminum foil or plastics material film of the kind used, for example in the kitchen or household in general. The saw-toothed blade must slightly protrude from the bottom front edge of the container to enable the user to tear out the portion of foil or plastics sheet to be used from time to time. The machine comprises a station in which the saw strips are severed from a metal tape and are applied to the flattened container, the latter being conveyed to the station by a conveyor belt assembly. The machine is equipped with appropriate cam and lever controlling and synchronizing means to have all the operative steps performed in the correct sequential order: the machine is compact and easily inspectable by one operator and the feeding means are all located on the longitudinal central axis of the machine. The station at which the metal strips are severed and applied to the cardboard sheets is placed nearly midway between the points at which the metal tape and the cardboard pieces are fed, these two materials being fed into the machine from opposite directions, that is, in counterflow relationship.
摘要翻译：公开了一种机器，其旨在将锯齿形刀片施加到容纳例如在厨房或家庭中使用的类型的铝箔或塑料材料膜的线圈或辊的容器（例如纸板）。锯齿状刀片必须从容器的底部前边缘稍微突出，以使用户能够不时地撕出要使用的箔或塑料片的部分。该机器包括一个工位，其中锯条被从金属带切断，并被施加到扁平的容器，后者通过传送带组件传送到工位。机器配备有适当的凸轮和杠杆控制和同步装置，以使所有的操作步骤以正确的顺序执行：机器紧凑并且由一个操作者容易地检查，并且进给装置都位于机。将金属带切割并施加到纸板上的工位几乎放置在金属带和纸板片供给的点之间的中间，这两种材料从相反的方向进给到机器中，也就是在逆流关系。
