  • Method and apparatus for controlling with increased accuracy a processing machine driven at varying operating speeds, such as a slide drawing machine, especially, as well as the slide drawing machine per se and auxiliary devices
    Patent number: 3999455
    Abstract: Method of controlling with heightened accuracy a processing machine driven t different operating speeds and having a machine part moving through a predetermined full range, the processing machine, at an initial setting of the moving machine part, within a given tolerance range, repeatedly permitting start-up of a processing cycle that has been instituted in advance through a precontrolled time period dependent upon the operating speed and which includes a control commencement build-up time period and a full range displacement time period, which includes interposing a blocking time period between the control commencement build-up time period and the full range displacement time period, the blocking time period always ending at the same position in the displacement range of the moving machine part, blocking the full range displacement by the moving machine part until the end of the blocking time period, and advancing the start of the control commencement build-up time period in accordance with the blocking time
    Type: Grant
    Filed: November 3, 1975
    Date of Patent: December 28, 1976
    Assignee: Schumag Schumacher Metallwerke Gesellschaft mit beschrankter Haftung
    Inventors: Walter Wetzels, Johann Greven, Wilhelm Romer, Heinz Hoppe
