ABSTRACT:
A spacer frame consisting of a hollow profile strip bent three times and still open at the fourth corner, wherein one leg (2) is longer than the other leg leading to the open corner, is filled with granulated desiccant by way of a probe (20) introduced into the leg (2). The probe (20) extends with its front end (20)into the leg (2') up to the desired filling level. As soon as the desiccant in the leg (2) has reached the probe (20), the feeding flow of desiccant ceases. This is detected by a sensor (27). The sensor (27) actuates the pulling out of the probe (20). During this step, a vacuum is applied to the probe (20) a distance from the front end (201) of the probe via a conduit (40) so that no desiccant can exit from the probe (20).
