Abstract

An injection moulding tool made from two opposing displaceable tool halves, for the production of plastic frames on pre-formed bellows for filter cassettes, with a comb-shaped row of teeth for clamping the longitudinal side edges of the bellows, during the injection process, arranged at a pre-determined folding angle and with terminal walls (15, 16) for clamping the end folds of the bellows during the process, whereby the terminal walls (15, 16) of the tool in the clamping region (6) of the end folds (3) are angled at the fold angle (4) of the end folds (3).
