Mounting preformed roller on shaft
Abstract
Abstract A ROLLER, SUCH AS A PRINTING ROLLER, IS FABRICATED BY SLIDING A CYLINDRICAL BODY HAVING A LONGITUDINALLY EXTENDING, SUBSTANTIALLY CENTRAL OPENING OVER A RIGID SHAFT DESIGNED TO SUPPORT THE ROLLER DURING ROTATION OR THE LIKE. THE ROLLER IS PREFERABLY CUT TO A DESIRED LENGTH FROM A PREFORMED, RELATIVELY LONG SECTION OF THE MATERIAL. A LUBRICATING ADHESIVE IS USED FOR THE JOINT PURPOSE OF FIRST LUBRICATING THE RELATIVE SLIDING MOVEMENT BETWEEN THE CYLINDRICAL BODY AND SHAFT DURING ASSEMBLY AND THEN ADHERING THESE PARTS TOGETHER AFTER ASSEMBLY. IN THE PREFERRED PRACTICE, A WET POLYMERIZABLE ADHESIVE COATINGS THE OPENING OF THE CYLINDRICAL BODY, AND A SECOND DIFFERENT ADHESIVE IS USED ON THE SHAFT. THE LUBRICITY OF BOTH ADHESIVES CONTRIBUTES TO THE SLIDING OF THE ROLLER RELATIVELY TO THE SHAFT, AND SUBSEQUENTLY THE TWO ADHESIVES FORM AND ADHESIVE BOND BETWEEN THEMSELVES AND THE PARTS TO WHICH THEY ARE APPLIED.
