Abstract: The invention is based on the problem of increasing the distance between the gripper and the mould half whilst maintaining the gripping power, so as to avoid damage to the contact lenses and the mould half, and of enabling the gripper to be simply aligned in relation to the mould half. This is solved by the usage of a spacer which is placed between the mould half and-the gripper. The distance between the mould half and the gripper is thereby increased without reducing the gripping, strength. In this way, damage to the mould half or the contact lens is avoided, and alignment of the gripper to the mould half is simplified. Moreover, the invention enables flaws in the periphery of the contact lens to be noticed more easily, since owing to the greater flux acting on the contact lens, the latter undergoes greater expansion in the end region of the gripper, thereby enabling possible flaws to be discerned more easily.
