Abstract
For two-side processing of optical lenses, the invention provides that blanks to be used for each lens body (7) comprise a chucking extension (18) whereby a single machine is sufficient for implementing the procedure. In addition to workpiece spindles (1, 2) as well as tool spindles (4, 5) with coarse tools (8) and finishing tools (9), the machine also includes an unloading device (10) and a loading device (13) which in successive interacting operations take the lens body (7) when processed on one side and at the circumference from a chucking tool (12) of the tool spindle (1) and turn it round for centered insertion in its inverted position into a chucking tool (15) of the tool spindle (2) for processing on the other side. The workpiece spindles (1, 2) may be mounted parallel to each other on a horizontally displaceable and vertically adjustable feed slide (3). A feed carriage (6) may displace and slew the tool spindles (4, 5) together with the unloading device (10) around a horizontal B axis. The loading device (13) is slewable around a further horizontal axis (C) between the workpiece spindles (1, 2) and the tool spindles (4, 5).

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
