AXIS ADJUSTMENT IN PRODUCTION OF TORIC CONTACT LENSES Russian patent published in 2011 - IPC B29C33/30 

FIELD: process engineering.

SUBSTANCE: invention relates to methods and device used in production of contact lenses. Proposed device serves to adjust coordinated relative position of first and second half-dies and comprises pallet with base, top surface and four lateral walls there between. It includes also multiple front curved cells each comprising curved wall and belt running radially. Note here that curved wall feature shape and sizes to allow accommodating front curved half-dies while belt features shape and sizes to allow half-die flange to be secured. Set of posts ups from pallet top surface. Note here that every post has top surface, lateral walls and multiple guide of eyes with shape and sizes allowing accommodation of half-die to prevent deflection and rotation of half-die.
