Abstract

A turning bar to deflect a moving web has part of its cylindrical periphery of porous air permeable material so that air may pass therethrough from within the bar to prevent the web making surface contact with the bar, which part is readily detachable from the rest of the bar for cleaning or replacement. 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. To render the bar useful for locks which are narrower than the bar length detachable covers are provided to mask off end portions of the porous part.

6 Claims, 6 Drawing Figures 9/1965 Canada 226/197 TURNING BAR FOR THE DEFLECTION OF PAPER WEBS 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. Especially in the case of freshly printed paper webs conducted between printing mechanisms of a rotary web printing machine, friction between the turning bar and the paper web leads to smearing of the printing ink.
A turning bar is already known which possesses a cylindrical periphery of porous, sintered material through which air escapes from the interior of the turning bar.
However, despite the air cushion it is not entirely possible to prevent contact between the paper web and the turning bar, and ink is thus transferred to the periphery of the turning bar, resulting in clogging of the pores in the sintered material. The turning bar ultimately becomes incapable of functioning properly and must be replaced. However, for this purpose the turning bar mountings and the air connections to it have to be disconnected. Under favourable circumstances the turning bar can then be cleaned after dismantling, but the cleaning of the entire turning bar is complicated, and it is important that the turning bar is freed of cleaning agent, after cleaning, in order to avoid corrosion.
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.
In accordance with the invention, 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. Thus it is only necessary to replace that part of the turning bar which becomes smeared with ink, and the remainder of the body of the turning bar with its air connections can remain in the machine. 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.
Preferably 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.
In the invention device for rapid securing of the segment on the turning bar is provided. In the case of a rigid segment fastening with a few screws is advantageous; on the other hand for a flexible segment a rapidly operable clamping device is especially suitable.
In a further development of the invention a device is provided 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.
Embodiments of the invention by way of example are shown diagrammatically in the accompanying drawings, wherein:
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; and
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. l
At each of the ends of the turning bar there is provided a device for covering the part of the porous segment 3 not covered by the paper web (see also FIG. 3). At each end 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.
In another embodiment of the invention (FIGS. 4 and 5) 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. On the end wall 19 there is again provided an air connection 23 for the supply of air into the interior of the turning bar. The periphery 24 of the turning bar hollow body 18 comprises a plurality of openings 25 through which air can escape. Over this region of the turning bar provided with air outlet openings 25 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.
