Definitions

  • the detachable part can be secured by screws or may consist of a porous flexible sheet stretched over a perforated segment of the bar and secured by quick fastening devices.
  • detachable covers are provided to mask off end portions of the porous part.
  • the invention relates to a turning bar for the deflection of paper webs, the cylindrical periphery of which bar consists of porous, air-permeable material through which air from the interior of the turning bar can escape to atmosphere.
  • Such turning bars serve for the deflection of webs of material.
  • the air issuing from the periphery of the turning bar forms an air cushion between the turning bar and the material web and reduces the friction between the turning bar and the web.
  • friction between the turning bar and the paper web leads to smearing of the printing ink.
  • a turning bar which possesses a cylindrical periphery of porous, sintered material through which air escapes from the interior of the turning bar.
  • the invention has the object of avoiding the disadvantages of the known turning bars and of rapidly and easily eliminating the soiling of the porous surface of a turning bar.
  • a segment of the cylindrical periphery co-operating with the paper web is arranged to be easily detachable from the rest of the structure of the turning bar.
  • the segment can be replaced, or, since in comparison with the turning bar body it is small and convenient, can easily be cleaned on all sides.
  • the segment is made as an easily flexible covering body. It is possible for example to use porous cardboard which is cheap and therefore constantly renewable.
  • a device for covering that part of the segment which the paper web does not overlie in the case of smaller web widths.
  • This device has the advantage that it is always possible to use segments of equal width, since the area not covered by the paper web can be sealed off and thus air losses are avoided.
  • Covering plates coated with a synthetic plastics material can be used for coverings which are displaceable over the width of the turning bar. Since the covering plates do not come into contact with the paper web, they are also not soiled and do not need to be cleaned or replaced.
  • FIG. I shows a longitudinal elevation of a turning bar according to the invention, partly in section
  • FIG. 2 shows a cross-section of the same turning bar along the line 11-" in FIG. 1;
  • FIG. 3 shows a crosssection of the same tubing bar along the line III--III in FIG. 1;
  • FIG. 4 shows a longitudinal elevation of a further embodiment of a turning bar according to the invention.
  • FIG. 5 shows a cross-section of the turning bar along the line V--V in FIG. 4;
  • FIG. 6 shows a perspective illustration of the bar shown in FIGS. 4 and 5 with a segment removed.
  • the turning bar or roll 1 shown in FIG. 1 consists of a turning bar body 2 on to which there is screwed a segment 3 of porous, air-permeable material, by securing screws 4 (see also FIG. 2).
  • the turning bar body 2 con sists of two end discs 5, 6, through which a shaft 7 extends for securing in the side walls of a rotary web printing machine (not shown), and to which a cut-away hollow body 8 is welded.
  • Air is supplied to the interior of the turning bar through an air connection 9 provided on one end disc 5, which air passes through the porous material of the segment 3 and forms an air cushion between a paper web 10 looping around the turning bar and the segment 3.
  • the segment is sealed off from the turning bar body by packings ll, 12.
  • the securing screws 4 are arranged in depressions 13 of the hollow body 8.
  • a device for covering the part of the porous segment 3 not covered by the paper web (see also FIG. 3).
  • a cover palte 15 which can be coated with rubber or synthetic plastics material, is hooked on a projection 16 on the hollow body 8 of the turning bar and stretched over the segment 3 by a snap fastener 17.
  • the turning bar consists of a hollow body 18 which can be secured on the machine with projections 21, 22 provided on end walls 19, 20.
  • the periphery 24 of the turning bar hollow body 18 comprises a plurality of openings 25 through which air can escape.
  • a flexible segment 27 consisting of porous material is stretched by'an easily and rapidly operated fastening device 26. Asbest shown in FIG. 5, one end of the segment 27 is clamped fast between clamping eccentrics 28 and a clamping face 29 on the turning bar.
  • the clamping eccentrics 28 are secured on a shaft 31 which is pivotable by a hand lever 30.
  • the other end of the segment27 is held in holders 32 which aresecured on a pivotable shaft 3 3.
  • Tension springs 34 ensure taut tensioning of the segment 27.
  • the clamping of the segment 27 in the holders 32 is effected by a wedge action.
  • the segment end is introduced into an opening 35 having two opposite surfaces 36, 37 inclined somewhat towards one another. On an attempt to extract the segment end a ball 38 movable in the opening 35 is forced into a narrowing cross-section and the segment is clamped fast.
  • An aero-dynamic turning roll for supporting and guiding a web moving along an elongate path including an arcuate turn, said turning roll comprising an elongate generally tubular body, said body being composed of two longitudinally extending complementary parts, one of said parts being stationarily mounted and the other part having a substantially circularly curved cross-sectional outline and being made of an airpervious material, the outer surface of said other part being a surface for supporting and guiding the web; fastening means for releasably fastening said other part to said one part to constitute said tubular body; and conduit means for directing a flow of air into said body for causing air to escape through said other part, the escaping air forming an air cushion between said outer surface and the web moving over the roll.
  • said fas- 4. tening means comprise two quick-release fastening means each for rastening one of the longitudinal edges of said other part, one of said quick-release fastening means including a clamping means for clamping the respective longitudinal edge of said other body part against said one body part and the other of said quickrelease fastening means including a pivotally supported member and defining an inwardly narrowing slot, and a ball freely movable in a wide part of said slot whereby upon fitting the respective longitudinal edge of said other body part into said slot and past said ball, an outwardly directed pull acting upon said other part edge forcing the ball deeper into the slot thus anchoring the respective longitudinal edge in the slot.
  • said clamping member coacting with said strip and said slotted member being pivotally mounted on the strip.
  • an airimpervious cover member is attachable upon the outer surface of said other part to close off air passage through a corresponding surface portion of said other body part.
