Abstract
A guide for drawers comprises two elongated metal parts, mutually slidable along each other. One of said two parts has a wall conveniently bent to define a raceway ( ) with play for a wheel ( ) rotatably fastened to the other part. In the raceway ( ) a wall region ( ) is deformed to define a passage (d) having a predetermined interference for the wheel. A method of manufacturing the guide comprises the steps of bending a wall of a first one of said two parts to define the raceway ( ) with play for the wheel ( ), inserting a gauged template ( ) into a predetermined raceway region, deforming the raceway from the outside against the template to obtain the passage with a predetermined interference for the wheel in the predetermined region ( ). Also described is a guide manufacturing machine.
