Vertical graining machine

Abstract

Abstract AN IMPROVED VERTICAL GRAINING MECHANINE, FOR GRAINING ARTICLES HAVING TAPERED OR STRAIGHT SIDES AND BEING ROUND, SQUARE OR RECTANGULAR IN CROSS SECTION AND PROVIDED WITH ROUNDED CORNERS, OF THE TYPE HAVING A FRAME WITH A HORIZONTAL SURFACE MOUNTING SUBSTANTIALLY VERTICAL MASTER AND PRINTING ROLLS, THE MASTER ROLL HAVING A GRAINING PATTERN ETCHED THEREON AND BEING CONTINGUOUS WITH THE PRINTING ROLL, INKING MEANS TO INK THE MASTER ROLL, GEAR MEANS JOINING THE MASTER AND PRINTING ROLLS, DRIVE MEANS MOUNTED WITHIN THE FRAME AND CONNECTED DIRECTLY TO AT LEAST THE PRINTING ROLL, AND WORK HOLDING MEANS FOR HOLDING THE ARTICLES TO BE GRANTED CONTIGUOUS WITH THE PRINTING ROLL. THE WORK HOLDING MEANS COMPRISS A VERTICAL BACK-UP PRESSURE ROLL, A PRESSURE ROLL DRIVE SHAFT ADJACENT THE FRAME AND COAXIAL WUTH THE PRESSURE ROLL, THE DRIVE SHAFT MOUNTING THE PRESSURE ROLL AT ONE END THEREOF AND BEING PIVOTAL ABOUT THE OTHER END SO AS TO ADJUST THE POSITION OF THE PRESSURE ROLL AS DESIRED, THE PRESSURE ROLL DRIVE SHAFT BEING OPERATIVELY CONNECTED INTERMEDIATE ITS ENDS TO THE DRIVE MEANS OF THE GRAINING MACHINE SO THAT THE SURFACE SPEED OF THE LARGE BASE OF THE PRESSURE ROLL IS SUBSTANTIALLY IDENTICAL WITH THE SURFACE SPEED OF THE PRINTING ROLL, AND MEANS TO LOCK THE PRESSURE ROLL DRIVE SHAFT AND THUS THE PRESSURE ROLL IN A DESIRED POSITION.
