A centring device for centring a packaging film for a forming unit of a packaging machine, comprises a support structure connectable to the forming unit; centring elements connected to the support structure and movable between a rest configuration and an active configuration for compressing the packaging film against a guide body of the forming unit; actuation members connected to the centring elements so as to align the packaging film in accordance with a predefined sliding axis thereof. The rest configuration corresponds to a static position whereas the active configuration corresponds to a dynamic position, in which the centring elements are in contact with the film so as to align it with the sliding axis. The centring elements can only be selectively activated under conditions in which the film is skidding with respect to the sliding axis.

The invention relates to a method for manufacturing a pod (100) for preparing a beverage in a beverage production machine, the machine having opening elements for opening the pod (100) under the effect of rising pressure of fluid being injected into the pod (100). In the method, two formable sheet elements (200) are provided, into one of which an opening (210) is cut. A second sheet material (300) is provided and connected with the respective sheet element (200) at a connection area (230) that circumferentially surrounds the opening (210). The so connected sheet material (300) forms a delivery wall (110) of the pod (100), through which during the beverage preparation process the prepared beverage is dispensed from the pod (100). The two sheet elements (200) are formed into the shape of a half-shell (101, 102), respectively, whereby the connection area (230) is pinched from opposite sides of the sheet element (200) when forming the respective half-shell (101, 102). An injection wall (120) for injecting a fluid into the pod (100) is formed. A substance (105) for the beverage is provided and the two half-shells (101, 102) are connected to form a pod body (130) around the substance (105). Therein, the pod body (130) together with the delivery wall (110) and the injection wall (120) delimit a chamber containing the substance (105). The delivery wall (110) is configured to be opened upon interaction with the opening elements of the beverage production machine under the effect of rising pressure of the fluid being injected into the pod (100).
