  • Mintz Attorney- Burgess, Dinklage and Sprung ABSTRACT An apparatus for compensating for the adverse effects occasioned by noncircularity of unwinding or delivery rolls in paper processing machinery such as roll cutting or slitting machines, rewinding machines and similar machines
  • APPARATUS FOR COMPENSATING FOR THE which operate in dependency upon a delivery roll and in EFFECTS OF NON'CIRCULARITY 0F which a measuring or sensing means influenced by the tensile UNWINDING ROLLS stress of a web fed from a delivery or unwinding roll controls a 3claims4nnwing Figs brake operably associated with the shaft or axis of such [52]
  • 242/7543 delivery roll comprising a low weight guide means interposed [51] Int. Cl. Bh 77/00 in the path of web travel between the unwinding or delivery [50] Field of Search 242/ .43, roll and the measuring or sensing means and acting upon such 75.42, 75.44, 75.3 web in pressure yielding fashion.
  • the present invention relates broadly to the art of winding and reeling. More particularly, this invention relates to the winding and reeling of paper and the like material.
  • this invention relates to an apparatus for com- In the processing ofcontinuous webs of. paper or the like, as
  • a web tension regulator compensating for the paper webs tensile stress is generally embodied in the machine subsequent to the unwinding apparatus.
  • the arrangement thereof is such that the paper web is conducted or passes over a pivotally mounted roller which swings out according to. each sensing of tensile stress, thereby imparting impulses to a brake which acts upon the unwinding axis or shaft.
  • the primary function of this type of web tension regulator is to adjustthetensile stress of the paper web to a preselected desired value by means of appropriately acting upon the .brake as said tensile stress increases due to the decreasing diameter of theunwinding'roll.
  • the primary object of this invention is to produce an apparatus which overcomes and removes the aforesaid drawbacks and difficulties and eliminates the paper stress fluctuations occasioned by noncircular unwinding rolls.
  • the spring-suspended arm is mounted for lateral as well as vertical adjustment and/or the effective lever length of the arm is adjustable. Furthermore, the arrangement can be such as to associate certain implements with the guide member which establish a friction-reducing air cushion between the paper web and the guide member.
  • a paper web 1 is pulled off from an unwinding roll 2and conducted to a rewinding roll 10 via a guide member comprising a pressure guide 3 having an areaate web-contracting surface and an arm 4, a measuring roll 5 is, a longitudinal cutting or slitting mechanism6, 7 and transportation rollers '8 and 9.
  • the measuring or sensing roller 5 carried by a lever arrangement 5"that is swingably mounted about axis 5" and by responding to the respective tensile stress of the web acts upon brake 11 through means which are well known to the art, said brake in turn acting upon the axis, or shaft of unwinding roll 2.
  • the paper web 1 is thereby acted upon in pressure-yielding I fashion by-pressure guide 3.
  • arm 4 of the guide member is mounted in aslot in an axis or shaft 12 so that it is adjustable and securably held, so that the pressure being exerted upon web I can be adjusted as desired by changing the effective length of lever arm'4.
  • Shaft 12 is rotatably and securably mounted in a bearing 13 which is attached to machine frame made possible as depicted in dotted line in FIG. 2, said adjustments being required in order to vary the pressure acting upon web 1.
  • FIGS 3 and 4 show as a further development of the invention the guide member 3, 4 having associated therewith implements 15,16 for producing an air pressure cushion-between pressure guide 3 and web 1.
  • the arrangement is effective to introduce compressed air between the paper webl and pressure guide 3 through several air. jets l7- distributed across the, width of the web for establishing an air cushion.
  • the air'jets l7 are connected with an air compressor not otherwise shown in the drawings through conduits 18.
  • machines include an unwinding axis for such an unwinding roll, measuring means influenced by the webs tensile stress, a brake operably associated with said unwinding axis, said measuring means being operably coupled to said brake for controlling the same in accordance with tensile stress variations, a light weight guide means interposed in the path of web travel between said unwinding roll and said guide, means comprising a resilient arm and means defining a shaped stationary guide surface engaged by said web from above, extending across the entire width of said web, and carried by said resilient arm and means for adjusting the position of said arm including means for swingably adjusting said arm and guide surface relative to said path of web travel about an axis parallel to said unwinding axis and
