Pivot Web Guiding SystemPivot Roll Guiding
This method particularly good for flexible web. It is available, when location in long distance between entry idler roll and exit idler roll The assumed pivot of the guide roll rotation be arranged to be long, so turning angle of the guider rolls and the tension variation are lesser, will reducing the wrapping of the web. There have 90° wrap for single roll and 180° wrap for double rolls shown as below.What Is Web?
A Web Is Any Flexible Material Which ls Processed From Roll in To A Product Lateral Wander Of A Moving Web In To Various Processes Telescoped Roll, Misalignment Of Machine, Air Turbulence, Hi Speed And Many Other Problem Encountered KMT Guiding System Accurate The Mistrack And Guide It Straight.Web Guide Benefits
REDUCED WEST,improved Product Quality. increased Production. Reduced Operator Attention, Quick Payback.Description
KMT-Tracking roller assembly TRA consists of two rectangular steel tubing frames. One is stationary, the other is movable. it is supported in a nylaguide sliding block accurate bar system or Linear bearing , and has ab idler roller at either end. The web can be fed over the TFIA in a 'U' shaped path, reversing its direction of travel, or thought the TRA in a ’2’ configuration .maintaining the same direction of travel. It is insensitive to attitude and can eve-n be mounted upside down. Solidly supported on all four corners by nylaguide bearings, linear hearing it is not subject to deflections caused by cantilever stresses. Radial bearings are sealed, and linear bearings are self-lubricating. The unit thereforeThe Principle
The TRA is designed so that it swings in an arc laterally, pivoting about an imaginary pivot point located exactly in the plane of the entering web path. The servo cylinder swings the other end of the frame, moving the outgoing web laterally back into the desired web path. Because the TRA correction range is increased by lengthening the span. Therefore the correction angel can be kept small to reduce induced stresses to the level desired. Because stresses can be kept minimal, the TRA can be used to guide within the tension loop on your process. It can be installed successfully on lines handling fragile material such as parchment paper, thin metal foil, or saturated paper even when other guiding methods have failed. It can also be used to make extremely large corrections in the web path, even displacing the shifting unwind, because of its very low inserted stress level.Center Guide System
KMT movable sensor guide systems are used primarily on processes to center the print regardless of web width variations during the process. The system will sense web width variations up to four l4)"inch with moving the sensor or affecting results, an in most cases will eliminate misprint process. Center guide can be used where great width variations. Its uses two air flow sensor each mounted on a nylaguide block and bar support connected to opposite sides of a common cable and two pulley arrangement. A single servo cylinder drive the air flow sensor in opposite direction the airflow censor in opposite direction the airflow sensor.
