Intermediate guiding system

" KMT " Tracking roller assembly (TRA) consists of two rectangular steel tubing frames. One is stationery, the other is movable; it is supported in a BEARING Guide

The Principle:

The improper mounting of the detector and improper arrangement of the rolls will result in unsatisfactory control performance, or will cause wrinkles to the web.
When planning and aligning the process line, the following described items must kept in mind. If distance is too short, winkles will happened on thin or soft web.

KMT 

when needed to correct web position in the middle of the process line, there are two methods to modify the web edge.

  • Center Pivot Roll Guiding :

    This method best applied to the webs of novelistic materials, or distortions web due to the difference tension of both side.
    The web hardly slips on this guide roll, since there has two 90°wrapped angle. If it is slips, use a rubber coated roll will prevent slip age occurs.

  • End Pivot 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.

Edge Position Controll :

Whenever the film roll is not feeding in order, it could be adjusted by EPC control unit and the film feeding will be corrected to the right position. This system will enhance the productivity of machine and there will provide one set of EPC for each line.

Turn Bar Web Guiding System For Lamination Plant

Turn Bar With Web Guiding

  • The turning bar is used wherever a 90 turn In the direction of the web is required. together with some adjustment of the web alignment.
  • The turning bar is installed at an angle of 45 to both the infeed and outfeed direction of the web.
  • The web winds itself around the turning bar 180 and leaves the guiding device at right- angles to the infeed position.
  • To correct the web path at the same time the turning bar is moved across the outfeed direction (in other words in line with the infeed direction) according to the guiding signal.
  • In order to avoid material stress turning bars can be supplied with an optional connection which puts a protective air cushion between the turning bar and the web

Description

Standard adapter bases consist of a stationary floor - mounted frame or plate, a four unit, standard bearing and support system, and a moving frame or plate. A heavy duty servo cylinder is mounted between the frames and the bearings. The servo cylinder moves the upper adapter base plate back and forth in response to hydraulic signals from the power unit.

Unwinding

  • If the material wound is irregular, this system guide the edge position and let it regularly into the subsequent process. The idler roll moves with the unwinding reel stand.
  • Mount the detector fixed and as close to the idler roll as possible.
  • The leaving web formed 3 angle at the deflector roll should more than 30“.if not possible,apply a pinhole added. The important, do not allow the web slip on this roll. The distance between two rolls should be more than the maximum width of the web.

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 therefore

The 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.
