PAPER WEB JUHNZNG WEBER Eawton A. Dix, New York, N. Y.
6 Claim.
This invention relates to improvements in members for securing together the broken ends at paper webs, and the invention also pertains to the processes for producing and using the same.
Hitherto, in the preparation of paper in continuous webs, as on a paper making machine and in rewinding and cutting machines, as well as in the feeding of such continuous webs to printing machines and the like, considerable difiiculty is occasioned due to the breaking of the web or webs while passing through the machines. This is particularly characteristic of paper making machines where the newly formed web at the wet or Fourdrinier end of the machine has very little tensile strength and, even though initially compressed in the calenders, may be readily disrupted. In rewinding machines and on printing presses, the breaking of the paper web or sheet is especially costly in both time and expense.
When a paper sheet breaks and it is desirable to make a splicing of the sheets, it is customary to square oif the edges and lap two meeting edges together, using paste or adhesives to secure them together, the securing action being increased or consolidated by passing the disjoined web members, as continuous sheets through the remainder of the machine. The strength of the joint in most instances is low and the machines must be run at just a moving speed until the joint has passed through the machine, and even under such circumstances the joint or splice does not always hold together.
To avoid the necessity of pasting the adjacent edges, of a broken sheet or web and to give greater strength to the joint, it has been proposed to use strips of adhesive material, such as gutta-percha, and the gutta percha may be compressed by a heated iron before starting the machine to secure the web members together. However, owing to the fact that gutta-percha is inherently brittle it has been found that rolls of relatively large diameter must be provided in the machine to provide suflicient flatness of curvature to avoid breaking or cracking of the gutta-percha joining member while the joint is being run through the machine. Where relatively small sized rolls are used, such as are normally used in rewinding machines and printing presses, this difiiculty is appreciably increased due to the smallness of the are or curvature of the surface of the rolls.
It is an important feature of this invention to provide an improved strip joining member for broken paper webs or sheets, and the like, which is non-frangible on any are of curvature.
It is a further feature of the invention to provide an improved paper web joining member of gutta-percha having means incorporated therein to prevent cracking of the same after being positioned to join the two ends of the paper web together. This improved joining member gives a material increase in the flexibility of the joint.
Yet another important feature of this invention is the provision and use or an improved gutta-percha joining member for paper webs, which member is characterized by a plurality of slot portions co-extensive with its length and disposed centrally of the member.
These and other desirable features and objects and advantages of the present invention will be described with reference to the accompanying drawing showing the mode of application of the improved, joining member with respect to paper webs and also showing a plurality of forms of said member, it being understood that the examples here disclosed are given by way of illustration only, as it is not intended to be limited in the structures or method herein shown, except as such limitations are clearly imposed by the appended claims.
In the .drawing like numbers'refer to similar parts throughout the several views, of which Fig. 1 is a side elevation, partly in broken section of the calendering end of a paper making machine;
Fig. 2 is a side elevation, partly in phantom view, of a reel or roll winding mechanism.
Fig. 3 is an idealized top plan view, partly in broken section, of a web showing a variety of methods and means of joining detached parts of the same;
Fig. 4 is a plan view of a portion of an improved web joining member; and
Fig. 5 is a view similar to Fig. 4 showing a modified form of joining member.
In the formation of paper, in a paper making machine, a web Ill passes through a plurality of stands of rolls, indicated generally by the numeral 20, each provided with a series of rolls 2i, which series or stands may be any desired number. The web I0 is woven through the several rolls and compressed and sometimes subjected to outside heat. The take-up end of the machine may be provided with a plurality of supporting standards 22 having bearings 23 adapted to receive shafts 24, which support the take-up rolls of paper II. The rolls II are driven through shafts 24 by suitable gearing, not shown, as are the calender rolls 2| of the machine.
In the construction shown in Fig. 2, there is disclosed a rewinding assembly comprising a O printing presses.
standard 40 mounted on a base 4| and provided with idler or cradle rolls 42 on which a take-up reel I lb is adapted to be rotatably supported and moved thereby. The rolls 42. are mounted on 5 shafts 43. A take-oil roll He may be mounted between a pair of standards 45 being supported on a shaft 46. The web I!) from the take-oil roll is shown as broken at the top of the roll, a joining member 30 being disposed between the broken portions, as shown more in detail in Fig. 3 A like break is shown in the drawing on the takeup roll lib. Guide rolls 41 are provided for directing the web and a smoothing or riding roll 48 is provided at the top of roll llb and is adapted to engage and smooth down the web ID as it is rolled up on the circumference of the roll llb. The roll lib may be driven through the rolls 42 in any suitable manner, not shown, and forms, per se, no part of the present invention. Suitable pressure may be applied through roll 48 to cause the web I0 to form a close compact will be understood that such showing is intended to cover the breaks in the paper web occurring in any part of the machines. When a break occurs, a strip 30 of a suitable 'gutta-percha composition is placed between the meeting edges of the broken web, which have usually been previously trimmed to remove jagged portions.
The joining member 30 may be made of a gutta-percha and parafiin composition and is caused 40 to adhere to the overlapped. webportions for example, Illa and "lb, by means of suitably applied pressure and/or heat, either by hand tools or other means.
The joining members 30 of the present invention are characterized by a degree of bendability transverse to the longitudinal axis or center, which permits them to be bent over relatively small diameter rolls without cracking, such rolls being standard in paper making machines and With the larger diameter of roll, there is less tendency of the brittle guttapercha members to crack, due to the flatter curvature of the surface.
these cut-out sections may be disposed over the surface of member 30 in any desired arrangement, as for example in Fig. 5 and in the lower section of Fig. 3, and along the edges as indicated at 3| 0. Y
The old form of joint was non-bendable and stiff and in passing around a small diameter roll caused the paper web to break as one edge of the joint would be held close to the roll and the other edge due to the stiffness of the joint would not conform to the roll and would therefore stand out from it, thereby creating a sharp edge over which the paper sheet under material tension is stretched. The added tension, due tothe paper being forced away from the roll by the stiff joint, and the sharpness of the edge of the joint operate to break or cut the paper at the edge of the joint.
While the above described structure of joining member functions very satisfactorily, other forms may be readily employed so long as there is willcient flexibility for the joint to bend around a small diameter roll without the paper web breaking.
By the use of these improved flexible joining members, it is possible to use them directly on paper making machines, rewinding machines or printing machines, without reference to the size of rolls over which the paper is passed at any stage of its manufacture and use, and, due to the fact that the improved, perforated, joining strips may be made up in quantity, and kept available at a machine without requiring refrigcrating or other treatment, the application thereof to the mending of broken webs is greatly facilitated. In addition, due to the fact that these improved, perforated joining members are dry, it is not necessary to use glues, paste or other materials, which are inherently messy, and which also have the disadvantage of having an appreciably lesser adhesion capacity than the improved flexible pressure-flowed gutta-percha member or its equivalent. Such improved joining strips are of particular use in printing presses where the available working space is at a substantial minimum, and the improved strips may be passed through the machine on holders or the like with the greatest facility and case.
While the improved joining members 30 have been disclosed as single strips having cut-out portions 3|, 3la, 3") and the like, it will, of course, be appreciated that a plurality or pair of strips may be laid in parallel and joinedby separate transverse strips of any desired size and configuration whereby to secure the same effective result. Owing to the type of material used, these members may be joined together to form a substantially continuous strip having lateral or continuous edge sections joined by a plurality of transverse fingers or bridging sections to form a continuous hinge or longitudinal bendable member. This improved unit type of joining members are much more easily handled and applied than the several members.
It will now be appreciated that there has been provided an improved method and means for joining paper webs in machines, whether in paper making machines, or in rewinding machines, or in printing machines, and irrespective of the size of the rolls over which the paper webs are passed or to be passed. This is made possible by the provision of a plurality of bridging sections or joining fingers between the main adhesive sections so that a bendable hinge member is formed which permits any desired degree of flexibility in the paper webs. It is also to be understood that the scope of this invention includes the adjustment or balancing of the thickness of the material being employed, the width of it, and the number and locations of the cutouts. Where there is greater thinness of the joining member then there may be a smaller number of holes or cuts-outs. This balancing gives the desired flexibility and paper functioning. The shapes, sizes and positioning of the holes or cut-outs usually have a bearing on the flexibility and successful results.
It will now be appreciated that there has been provided a new and novel means and method for combining or joining broken segments of continuous fabrics, and particularly in machine operations where the fabric is to be wound upon or unwound from supply reels. In addition, the improved article and process permits the rapid, economical and secure joining of broken webs of 2p fabric or paper, and in machines, by means of pressure-plasticizable strips which are provided with a plurality of desirably shaped joining sections which may be cut out from the body of the mass and which permit the use of normally 25 brittle members on rolls having diminished arcs of curvature as opposed to the structures hitherto required and which were characterized by the relatively large arcs of curvature to prevent bending and breaking of the joining strips. The in- 30 vention is further characterized by utilization of strips of gutta-percha or like frangible materials which, although capable of exerting a cementing action when subjected to pressure and/or heat do not lose their normal brittleness.
