Title: Process for suppressing undesirable vibrations of the print support in a vector-type plotter, and plotter implementing this process
Inventor: DELAPLACE ETIENNE X
IPC: G01D15/28
Filed: 1991-06-17
Abstract: The system applies to a drawing machine of the vectorplotter type, in which the drawing is made by combining movements of the sheet in a first direction (X) and movements of a writing implement in a second direction (Y), as a function of vectors compiled from graphical data supplied to the plotter. According to the present system, there is undertaken a step of detection of critical conditions liable to engender undesirable vibrations of the sheet following which, in response to a detection of these critical conditions, the movements are interrupted for a specified duration. Preferably, detection of the critical conditions comprises a step of detection of critical vectors and a step of detection of critical sequences of vectors containing a first and a second critical vector which follow one another in time in a not necessarily consecutive manner, and the interrupting of the movements is effected by introducing a delay between the first and the second critical vector.
