Abstract: The invention concerns a device in which a blocking arm (13) is mounted on a carriage (15) in such a way that it pivots between a raised loading position and a pivoted fitting position. According to the invention, between the blocking arm (13) and the carriage (15) there are pawl-type engagement means (38, 40) capable of a releasable locking of this blocking arm (13) on this carriage (15) when it is in the pivoted fitting position. Application to the blocking of any grasping stud on a spectacle lens workpiece.

Abstract: A particular measurement on a template is known to be D(0) and is measured on the profile reader as D(1) such that D(1) = D(0) + X; X being the profile reader error. After the trimming machine has made a copy of the template the corresponding measurement is actually D(2) = D(1) + Y; Y being the trimming machine error. The profile reader is then used to measure the dimension on the copy made and the reading taken is D(3) = D(2) + X. It is known that X the profile reader error is substantially constant and this allows both the profile reader and trimming machine errors to be determined.
