Method and device for inspecting flexible container

摘要

A method for testing a flexible container includes arranging the flexible container on a winding core that can be rotated about a winding axis W and forms an internal support. The method continues by winding the flexible container around the winding axis W arranging an external support around the wound container and connecting at least one container opening of the container to a fluid source. The method proceeds by filling the container with a fluid from the fluid source to generate a predetermined positive pressure P1 in the flexible container at a first time T1 and determining whether the container is sufficiently leaktight.

1. A method for testing a flexible container, comprising the steps:
arranging the flexible container (3) on a winding core (5), which can be rotated about a winding axis (W) and forms an internal support (5), a separating means (9) which is formed as a windable sheet (41) being fastened on the winding core (5) with a width extent (X) parallel to the winding axis (W); winding the separating means (9) together with the flexible container (3) around the winding axis (W) so that each successive winding of the separating means (9) and the flexible container (3) is farther from the winding axis (W); arranging an external support (17) around the wound container (3); connecting at least one container opening (13) of the container (3) to a fluid source (33); filling the container (3) with a fluid from the fluid source (33) in order to generate a predetermined positive pressure (P1) in the flexible container (3) at a first time (T1); determining whether the container (3) is sufficiently leaktight.
