    • An process and apparatus for packaging a product arranged on a support (4) is disclosed. The apparatus comprises a packaging assembly (8) configured for tightly fixing one or more film sheets (18) to one or more supports. The packaging assembly (8) includes a lower tool (22) comprising at least an inner wall defining a prefixed number of seats for receiving the supports, and an upper tool (21) facing the lower tool and comprising a film holding plate (36) configured for holding the one or more film sheets, the film holding plate having a respective active surface (37) configured for receiving the one or more film sheets (18), at least the upper and lower tools (21, 22) cooperating to define a packaging chamber (24). The packaging assembly (8) is configured to operate at least in a first operating condition, where said packaging chamber is open to receive the one or more film sheets, and in a second operating condition, where said packaging chamber is hermetically closed. The film holding plate (36) has a lateral surface extending substantially perpendicular to a plane defined by the active surface (37), the film holding plate (36) comprising a plurality of ejectors (36c) arranged in the lateral surface, each of the plurality of ejectors being configured for ejecting a stream of gas in a direction substantially parallel to said plane and substantially away from a center of the active surface (37). The process includes the step of activating ejection of a plurality of streams of gas around a perimeter of the film holder and over a peripheral portion of cut film sheets in a direction substantially parallel to a plane defined by the cut film sheet and away from a center of the cut film sheet, in order to position and/or maintain the peripheral portion substantially within the plane of the cut film sheet.
    • 公开了一种用于包装布置在支撑件(4)上的产品的工艺和装置。 该装置包括被配置用于将一个或多个胶片片(18)紧密地固定到一个或多个支撑件上的包装组件(8)。 包装组件(8)包括下部工具(22),该下部工具至少包括限定用于接收支撑件的预定数量的座的内壁,以及面向下部工具的上部工具(21),其包括膜保持板(36) 被配置为保持所述一个或多个薄膜片,所述胶片保持板具有构造成用于接收所述一个或多个胶片片(18)的相应的活动表面(37),至少所述上部和下部工具(21,22)协作以限定 包装室(24)。 包装组件(8)构造成至少在第一操作条件下操作,其中所述包装室打开以接收一个或多个薄膜片,并且在第二操作条件下,所述包装室被气密地关闭。 膜保持板(36)具有基本上垂直于由有源表面(37)限定的平面延伸的侧表面,膜保持板(36)包括布置在侧表面中的多个喷射器(36c) 多个喷射器被配置用于沿基本上平行于所述平面并基本上远离有源表面(37)的中心喷射气流。 该方法包括以大致平行于由切割薄片片所限定的平面并远离中心的方向激活多个气体流围绕胶片保持器的周边喷射到切割薄膜片的周边部分的步骤, 以便将周边部分基本上位于和/或保持在切割薄膜片的平面内。
