Verfahren zum teilweisen Füllen von Hohlkörpern mit Granulat

摘要

A spacer frame which comprises a hollow profile moulding bent-off three times and is still open at the fourth corner, one leg (2) being longer than the other leg leading to the open corner, is filled with a granular drying agent via a tube (20) which has been introduced into the leg (2). The tube (20) projects, with its front end (20'), into the leg (2) up to the desired filling height. As soon as the drying agent in the leg (2) reaches the tube (20), the inflow of drying agent ceases. A sensor (27) detects this. The sensor (27) activates the drawing-out operation of the tube (20). In this arrangement, subatmospheric pressure is applied to the tube (20) via a line (40) in order that no more drying agent is discharged out of the tube (20).
