Abstract
An improved device for translational movement of automatic drawing machine tools of the type having a frame connected to a drawing machine, a permanent magnet system, and a controlling plunger attached for free movement, with respect to said frame. The plunger is interconnected to a tool carrier which accepts a writing tool in a manner wherein an electromagnetic control coil around the plunger and the tool carrier are moved by a mechanical linkage, pivoted upon said frame, so that the plunger and the carrier are simultaneously moved in opposite directions. The linkage preferably comprises a closed band, which runs around and over two deflection rollers, so that its mutually opposing and essentially parallel side portions are respectively connected to the tool carrier and the plunger. The interconnecting linkage also includes means to statically compensate for the different weights of the plunger and carrier.
