ABSTRACT:
A drawing head for a drawing machine has a base plate with a central bore. he base plate is nonrotatably attached to the drawing machine. A rotatable straightedge support under the base plate has a central pin extending through the central bore. A nonrotatable cover plate is mounted on the pin with a gripping knob above the base plate. A spacing ring is rotatably positioned between the base plate and the cover plate. Locking devices are provided for releasably retaining the straightedge support with respect to the spacing ring and for releasably retaining the spacing ring with respect to the base plate. It is thereby possible to reduce the overall height of the drawing head while maintaining the bearing precision, and to thus achieve lower costs for production and assembly of the drawing head. Bearing means are provided whereby the central pin which engages the bore of the base plate is axially supported and rotatably positioned therein to firmly support the spacing ring. Moreover, the straightedge support is axially supported and rotatably positioned on the bearing means.
