    • A hot-stamping device (1) is described, having a stamping device (2) for transferring a transfer layer (15u) disposed on a carrier layer (15t) of a hot-stamping foil (15) onto a substrate (14). The hot-stamping device comprises a heatable stamping roller (11) and a counter-pressure roller (12), between which a stamping gap (16) is realized, in which a stamped substrate (17) is realized, and comprising a separating device (3), disposed downstream, for separating the carrier layer (15t) from the stamped substrate (17). The separating device (3) has a separating element (20), which is realized as a bar-shaped hollow body, disposed on which there is a supply for a compressed gas (21). At least one longitudinal edge of the separating element (20) is realized as a perforated separating edge (20k) having outflow openings (20a) for the compressed gas (22), for the purpose of realizing a gas cushion between the carrier layer (15t) and the separating element (20). The separating edge (20k) is disposed transversely in relation to the running direction and parallelwise in relation to the top side of the coated substrate (17).
    • 描述了一种热冲压装置(1),其具有用于将设置在热烫箔(15)的载体层(15t)上的转印层(15u)转印到基板(14)上的冲压装置(2)。 热冲压装置包括可加热冲压辊(11)和反压辊(12),在其间实现冲压间隙(16),其中实现冲压基板(17),并且包括分离装置 (3),设置在下游,用于将所述载体层(15t)与所述冲压的基板(17)分离。 分离装置(3)具有分离元件(20),该分离元件(20)实现为棒状中空体,其上设置有用于压缩气体(21)的供应源。 分离元件(20)的至少一个纵向边缘被实现为具有用于压缩气体(22)的流出开口(20a)的穿孔分离边缘(20k),以实现载体层(15t )和分离元件(20)。 分离边缘(20k)相对于运行方向横向设置并且相对于涂覆的基底(17)的顶侧平行放置。

    • A system is disclosed for sealing a metal foil membrane on the end of a container such as a composite container using a rotating turret having a plurality of spindles in it with non-metal rotating heads on the spindles for pressing a closure and foil membrane against the container sealing surface and rotating the container-closure assemblies about the axis of the container as they are moved through a magnetic field produced by an induction heating coil disposed at least partway around the turret. The container-closure assemblies may be moved through the magnetic field in less than one second to heat the sealing area of the foil membrane and metal foil liner in the container to the required sealing temperature while minimizing heating of the membrane beyond the area of sealing contact with the container. Either the foil membrane or container liner or both have a heat seal resin thereon which is softened or melted by the induced heat in the membrane and seals the membrane to the container when the container-closure assemblies are removed from the magnetic field.
