Definitions

  • a guide roll assembly for the traveling paper web including means for delivering such a traveling paper Web as for example used on a paper roll winder, and a freely .rotatable guide roll engaging the web with the surface partially wrapped thereby and being driven thereby.
  • the freely rotatable guide roll is provided with a plurality of venting means in the surface thereof, such as extending grooves of certain configurations, receiving the air carried over the roll surface body by the oncoming web and purging the same therebetween.
  • Another object of the invention is to provide an improved guide roll driven by contact with a paper web wherein the tendency to build up a cushion of air between the web and roll surface is eliminated and the roll thus will continue to have good contact with the traveling paper web and will continue to hold the web accurately in its path of movement and will continue rotating with a surface speed substantially at the exact speed of movement of the paper web.
  • a further object of the invention is to provide an improved paper web guide arrangement for use with paper web winders avoiding the necessity of providing expensive drives to maintain the guide rolls at the exact speed of paper web travel.
  • a still further object of the invention is to provide an improved guide roll structure which eliminates the formation of air bubbles between the web and roll and improves sheet tracking at light tensions with or without driving of the roll.
  • the invention contemplates providing a guide roll assembly for a paper web including means for delivering a traveling paper web, such as used in a paper roll Winder, and a freely rotatable guide roll engaging the web with the surface partially wrapped thereby and being driven thereby, and a plurality of venting means in the surface of the roll such as extending grooves of certain configuration receiving the air carried over the roll surface by the oncoming web.
  • FIGURE 1 is a schematic view showing rolls as arranged in a winder machine for handling a traveling paper web embodying a guide roll constructed and operating in accordance with the principles of the present invention
  • FIGURE 4 is a fragmentary plan view of the end of the roll of FIGURE 3;
  • FIGURE 5 is a fragmentary plan View of a modified form of guide roll
  • FIGURE 6 is a fragmentary plan view of another form of roll.
  • FIGURE 7 is a schematic fragmentary end elevational view of the roll of FIGURE 6.
  • FIGURE 1 shows a winder mechanism schematically with a paper roll 10- being wound supported on winder drums 11 and 12 with a rider roll 13 at the top.
  • the winder drums 11 and 12 are driven by suitable means and a paper web W is delivered to the roll at relatively high speed.
  • the web is received from suitable web supply means and is delivered as shown schematically by a roll 14 and passes over a guide roll 15.
  • the guide roll 15 supports the span of web between the web delivery means in the form of the roll 14 and the web receiving means in the form of the drum 12.
  • the web is received by being unwound off a supply roll (not shown) before it passes onto roll 14 and for convenience the roll 14 may be referred to as the supply or delivery roll inasmuch as it transports the supplied or delivered web on to the guide roll 15.
  • the guide roll 15 is a freely rotating roll having a small angle wrapped by the web and driven by surface engagement with the web. While the guide roll 15 is shown schematically in a location leading directly to the winder it will be appreciated that various other locations may be employed.
  • the building up of the air cushion 17 also causes lateral skidding of the sheet causing it to deviate from its path which is highly undesirable as far as the operation of the winding mechanism is concerned.
  • Plain surfaced roll 15 has relatively substantial mass and once the web W has sufficiently driven the roll 15 to a substantially matching linear speed of the traveling web, the roll 15 will tend to continue at that relatively high speed from its resulting inertia. When the web W decelerates, as previously explained, and again contacts the roll surface, the inertia of the roll mass resists the change of speed and will cause scorching, slippage, and similar damage to the web which is highly undesirable as far as the finished paper product and the operation of the winding mechanism is concerned.
  • a guide roll 16 is provided, FIGURES 3 and 4, which has imperforated recesses in the surface preferably in the form of extending grooves 18.
  • the venting means may be axially extending grooves and ridges machined onto the surface of roll 16 or the grooves may be preformed onto a suitable cover which is then fitted onto the periphery of a suitable roll.
  • the grooves 18 have an open top at the roll circumference and a closed bottom interior thereof so as to form an imperforate roll.
  • discrete recesses or bottomed holes may also be used.
  • the air carried over the roll surface is vented by the grooves to ambient atmosphere (where discrete holes are used, the air is briefly compressed within the holes) permitting the web to maintain contact with the surface area between the openings and properly track in the proper direction.
  • the grooves 18 must be of an axial dimension to prevent sheet marking and that the axial dimension of the grooves is preferably in the range of to inch, and the recesses should cover no more than 40% of a total surface of the roll in order to avoid sheet marking and provide adequate surface area for engagement between the roll surface and web.
  • the arc of wrap of the roll by the web extends over an arc of between to 60.
  • venting means serve not only to vent the oncoming air from beneath the traveling web as it contacts the roll surface, but additionally reduce the overall mass of the roll so that it does not develop any substantial inertia. It is advantageous to use as light a mass as possible consistent,
  • imperforated guide rolls having extending grooves are uniquely well suited.
  • the grooves serve the dual function of removing a substantial amount of mass from. the roll and venting air from the underside of the web as it passes over the roll.
  • the grooves are bottomed and the roll still maintains a solid shell, at least at the inner extremity of the grooves, no substantial sacrifice of strength is necessary and materials presently being used for guide rolls can continue to be safely used.
  • the relatively narrow groove axial'dimensions allow suflicient land areas to fully support the web and vent the oncoming air.
  • FIGURES 5, 6 and 7 show an arrangement where the guide roll 22 (and alternatively guide roll 22, as shown in FIGURE 6) is provided with other configurations of grooves to permit the escape of air.
  • the guide roll 22 is provided with grooves 23 (and alternatively grooves 23' as shown in FIGURE 6) which extend preferably the entire length and open at the end of the roll 22 as shown at 24 to provide escape channels.
  • the grooves are prefer ably non-linear axially and certain forms of grooves are shown, and other groove forms may be employed which do not tend to shift the paper web axially relative to the guide roll.
  • the present arrangement is employed at low web tensions in the range of less than 10 pounds perinch of web width.
  • patterns different than FIG- URES 5, 6 and 7 may be used such as other herringbone patterns, and parallel grooves which extend inwardly at an angle to the roll axis from both ends to meet at the midpoint of the roll surface, either extending generally axially or generally circumferentially.
  • a guide roll assembly for paper web handling machines, the combination comprising, means receiving a traveling paper web, roll means engaging the traveling web with a span between said receiving and engaging means, an imperforated freely rotatable guide roll en gaging the web in said span throughout a relatively small arc, and a plurality of venting means in the surface of said guide roll purging air carried over the roll surface by the oncoming web, said venting means defining an open area at the roll periphery of not more than 40%.
  • venting means comprises relatively narrow axially extending grooves receiving air carried over the roll surface by the oncoming web to avoid forming an air film lifting the web off said guide roll to avoid thereby marking the web.
  • a guide roll assembly for a paper web handling machine, the combination comprising, means receiving a traveling web of paper, roll means engaging the traveling web with a span between said receiving and engaging means, an imperforated freely rotatable idler guide roll engaging the web in said span with the roll surface partially wrapped thereby and being driven thereby, and a plurality of alternating ridges and grooves in the surface of said roll with the grooves receiving air carried over the roll surface by the oncoming web, said grooves having an open top at the roll circumference and a closed bottom, each groove extending on the roll surface so that when a first portion of the groove is beneath the Web on the roll and said portion is closed by the web spanning the ridges each side of another portion of the groove communicating with said first portion is free of being closed by the web and is exposed to the atmosphere so that air can escape from the open top of the groove to the atmosphere, said grooves defining an open area of not more than 40%.
