Copying method and device

A system for producing an article from a blank, the contour of the article being altered with respect to a selected model by using a copying machine including:

• a first pair of units having a first unit for supporting the model and a second unit for supporting the blank and a second pair of units including a third unit for supporting a detecting member, and a fourth unit for supporting a machining member;
• means for controlling said units of said first and second pair for execution of first relative longitudinal displacement movements of said pairs of units towards and way from each other such that said detecting member is brought in cooperation with the model for detecting its contour and the machining member is brought into contact for working upon the blank;
• a first linkage system associated with said first pair for controlling one of said first and second units in said first pair such that the other of said first and second units executes second displacement movements with respect to the one unit to provide a desired alteration of the article contour in the longitudinal direction;
• a second linkage system associated with said second pair for controlling one of said third and fourth units in said second pair such that the other of said third and fourth units executes second displacement movements with respect to the one unit to provide a desired alteration of the article contour in the radial direction;
• and
• wherein said units are positioned such that longitudinal axes of said first and third unit relative to said second and fourth unit respectively are at an angle with respect to each other.

• said second linkage system comprising a second link arm which is mounted at a fixed point and extends across said third and fourth units of said second pair which are arranged in parallel, said second link arm at its free end being provided with manually actuatable adjustment members for manual adjustment of a percentage value of the second displacement movements of the said second pair of units, and wherein the link arms of the second linkage system comprise further links for transferring movements from the one unit of the second pair to the other unit.
