摘要： The tear-strips are formed by transverse cutting of a sheet material by a cutter with a rotary blade, of which the blade cooperates with counter-blades carried by a rotary member. Once formed, each tear-strip is held on the respective counter-blade, for example, by means of a vacuum, so that it can be transferred to a sheet of wrapping material. The tear-strip is applied to the wrapping material transversely by the combined action of the counter-blade and of a striker block carried by a further rotary member disposed on the opposite side of the sheet material. The sheet material can thus advance at a constant speed throughout the process of applying the tear-strips. The preferred use is for automatic packaging machines for products such as food products.

摘要翻译： 撕条通过具有旋转刀片的切割器横向切割片材形成，其中刀片与由旋转构件承载的反向刀片配合。 一旦形成，每个撕条被保持在相应的反向叶片上，例如通过真空，从而可将其转移到一片包装材料上。 通过反叶片和由设置在片材相对侧上的另一旋转构件承载的撞击块的组合作用横向地将撕条施加到包裹材料上。 因此，在施加撕裂带的整个过程中，片材可以以恒定的速度前进。 优选的用途是用于诸如食品的产品的自动包装机。
