AN APPARATUS FOR INTERMITTENTLY DRAWING AN ENDLESS BELT IN AN AUTOMATIC SCREEN PRINTING MACHINE AND AN AUTOMATIC SCREEN PRINTING MACHINE INCORPORATING SAID APPARATUS

摘要

In an automatic screen printing machine of the roller intermittent drive type, errors of feeding of an endless belt by a driving roller are effectively eliminated by preliminarily correcting feed errors owing to unevenness of the thickness and elongation of the endless belt by increasing or decreasing the pulse number representing the repeat length of the endless belt and controlling feeding of the endless belt at every repeat based on the increased or decreased pulse number.
