![]() ![]() As measurements at each roller end are taken and the difference between these readings is calculated, one can map the position of every roller in the horizontal plane.Ĭlick here to download the free “Roll and Web Alignment” whitepaper by Pinpoint Laser Systems. Introducing the 90-Line into the laser path redirects the laser across the face of the roller to be measured. ![]() Pinpoint has developed a practical tool called the Vertical Roll Adjuster.įor checking roll parallelism, the laser beam is directed along the outside edge of the machine and becomes a fixed laser reference line that does not move. Once again, a height reading is taken at the left and right side of each roller and the difference between these two readings shows how the roller sits relative to the reference plane.Īn alternative to using a precise plane of laser light is to use a bubble level for setting the vertical orientation of rollers in a system. For laser leveling, the laser light is directed across the top of the rollers and the digital receiver and display provide readings of the roller position, relative to the plane of laser light. Pinpoint offers solutions for both of these approaches. The Laser Microgage can measure rolls that are straight or crowned and can also be used to detect roll defects.Ĭhecking roll parallelism in the vertical orientation can be done by either of two methods: laser leveling or adjustment with a machinist’s level. The receiver is then moved along the top of the roller while staying in the beam path to record height or surface deflections. Pinpoint Laser System’ unique 2-dimensional Microgage is designed for precision measuring, machine alignment, calibration, and other demanding industrial applications. The laser is projected across the top of the roll surface and adjusted so that the receiver readings at one end match the readings at the far end. The profile of a roller is easily checked using the Laser Microgage. In addition, a variety of accessory products and mounts are available that allow the Microgage to be adapted to a wide range of applications. If the receiver or laser moves, relative to each other, the display values will change in real time. This information is then transferred to a digital display unit that clearly indicates the precise position of the receiver in relation to the laser position. The Laser Microgage has a compact digital receiver that precisely detects the incoming laser beam. This whitepaper explains the general use of the Laser Microgage for various aspects of roll alignment.ĭownload the “Roll and Web Alignment” whitepaper to learn: The alignment of rolls and web systems is necessary to achieve efficient operation, improve productivity and reduce production downtime. Many manufacturing facilities operate equipment that contains rollers, idlers, press drums, and web handling systems. “Roll and Web Alignment” is the newest installment in the Pinpoint Laser Systems Alignment and Measuring Whitepaper Series. ![]()
