<p>The method of cutting lengths of glass from a ribbon of glass of the parent Specification is modified by the use of two independent measuring means, e.g. graduated rods, that will enter into locking engagement with the guideway, so enabling one measuring means to be adjusted to another cutting length while the other is controlling the length to be cut. Remote control of the setting of the graduated rods may be provided by photo-electric counting of slits in a screen carried by each rod with means to stop the movement of the rods after a number of impulses have been recorded corresponding to the desired cutting length.</p> |
