BI-TEXTURED WINDER DRUM Filed Feb. 13, 1964 EIE- re INVENTOR United States Patent 3,240,442 BI-TEXTUREI) WINDER DRUM John A. Kilmartin, Berwyn, Pa., assignor to Beloit Eastem Corporation, Downingtown, Pa., a corporation of Delaware Filed Feb. 13, 1964, Ser. No. 344,570 7 Claims. (Cl. 24266) The present invention relates to improvements in winders such as paper web winders wherein a travelling paper web is wound onto a large roll supported on winding dums.
The invention contemplates providing means for supporting and rotating a winding roll including a winder drum having a cylindrical non-yielding outer surface with a spiral groove formed in the drum surface filled with a resilient rubber filler supportin-gly engaging the outer surface of the web as it is being wound and preventing the capture of air between the inner surface of the web and the roll as it is being wound. This entrapment of air occurs when a conventional spiral pattern is out below the supporting roll surface. The web conforms to the bi-level surface but the winding roll is supported by the high areas and bridges this undercut grooving. Air is drawn in between the web and the winding roll.
In the paper web winder wherein the roll is supported on winding drums at the back drum nip air tends to be trapped between the outer layer of paper and the winding roll. This air tends to be squeezed out at the front drum nip causing wrinkles to form in the roll and causing uneven winding and damage to the quality of the paper.
It is accordingly an object of the present invention to provide an improved method and mechanism for winding a paper roll which will eliminate the problem of damage to the roll and paper web due to air being trapped between the paper web and roll.
A further object of the invention is to provide an improved 'back drum for a paper web winder which has an improved structure for maintaining good support and traction between the drum and roll and yet which will prevent the entrapment of bubbles of air in the rewound roll.
A still further object of the invention is to provide an improved winding drum structure having strips of resilient material on the surface wherein the material is firmly held and supported by the roll and has a structural relationship to the roll for optimum winding operation.
Other objects, advantages and features will become more apparent with the teaching of the principles of the present invention in connection with the disclosure of the preferred embodiments thereof in the specification, claims and drawings, in which:
FIGURE 1 is a schematic end elevational view of a winder machine constructed and operating in accordance with the principles of the present invention;
FIGURE 2 is a fragmentary elevational view of the winder drum of the winding machine of FIGURE 1;
FIGURE 3 is a fragmentary sectional view taken substantially along line III-1H of FIGURE 1; and
FIGURES 4 through 6 are fragmentary sectional views similar to FIGURE 3 illustrating modified structural arrangements.
On the drawings:
FIGURE 1 shows a roll 10 being wound with a travelling web W guided to the roll by a spreader roll 13. The web is received at a substantially continuous speed from the paper machinery such as paper making or converting machines such as from a slitter. The roll 10 is started being wound on a center core 10a and wound to 3,240,442 Patented Mar. 15, 1966 the desired size whereupon the web is transferred to a fresh core and a new winding operation started. A rider roll 14 may rest at the top of the roll 10 for aiding and controlling the uniformity and tension on the roll 10.
The roll is supported on winding drums 11 and 12 with one or both being suitably driven to rotate the roll 10.
A phenomenon which occurs during winding, particularly at higher speeds, is the entrapment of air between the paper web W and the roll 10 at the nip N formed between the back drum 12 and the roll 10. The air tends to be squeezed out at the nip formed between the roll 10 and the front drum 11 causing wrinkles to form in the paper. For avoiding this disadvantageous result the present invention provides grooves in the cylindrical non-resilient outer surface 15 of the drum 12, with the grooves being filled with a resilient material such as rubber.
As shown in FIGURE 2 a groove 17 is cut in the outer surface 15 in a helical shape preferably with helixes in opposite directions starting at the center of the roll for a spreading effect. The groove is filled with a strip 16 of rubber which fills the groove at least to the surface 15 of the drum 12 so as to maintain surface engagement with the web W and to retain the required support and traction between the drum and roll 10. FIGURE 3 shows the rubber strip material 16 seated in the grooves, being cemented or otherwise suitably held in the groove 17.
I have discovered that the varying friction component between the hard outer surface 15 of the drum, which is preferably of metal, and the filler material 16 will act in a normal spreading pattern. Also, compression of the material 16 into the groove will permit normal action of the non-compressing metal surface 15. This will stabilize the winding 'in a lateral direction.
I have also discovered that this avoids the entrapment of air between the layer W of the web and the surface of the roll 10. The theory of operation which I believe occurs, but by which I do not wish to be non-yieldably bound, is that a level surface will present a closed nip at the point where the web meets the roll 10. However, yielding material 16 will permit penetration of sections of the roll 10 while continuing to resist entry of surface air. Any degree of displacement of yielding material 16 will permit non-yielding surface areas 15 to perform their advantageous spreading or stabilizing function. The compression of the material occurs as the material and web are entering the nip N and as the air compresses it is immediately forced out of the nip. If the yieldable material 16 extends above or is crowned to project above the non-yieldable surface area the spreading action will be greater without loss of benefit in resisting air entrap ment. Since the rubber material is substantially noncompressible it displaces into the nip. Thus an air rejection nip is in effect formed permitting and, in effect, compelling the ejection of air moving into the nip improving engagement between the drum and the roll 10, and improving the uniformity of the web as it is laid against the roll 10.
The straight line of contact between the drum 12 and the roll 10, and the worming action through the varying friction components of the metal and rubber, and additional worming action at the rubber relieves itself in the grooves under pressure, improves the winding operation and the overall operation of the winding mechanism permitting higher speed operation.
FIGURE 4 illustrates an arrangement for improving and insuring that the rubber strips will remain in the grooves. Grooves 19 are cut into the metal outer surface 18 of the drum with undercut portions 20. The rubber strip 21 is formed to fit into the undercut portions 20 for holding the strip in place.
FIGURE 5 illustrates an arrangement wherein grooves 23 are cut into the metal outer surface 22 on the drum and filled with rubber strips 24. The strips are crowned at 25 to project above the cylindrical surface 22 and insure frictional traction between the strips and the drum.
FIGURE 6 illustrates an arrangement wherein grooves 27 are cut into the hardened outer cylindrical surface 26 of the drum and filled with strips 28 of substantially rectangular cross section but which are slightly higher than the depth of the groove to project above the surface 26 of the drum.
In the preferred constructions the spiral grooving should have a lead in the range of 1 A" to 1%. The width of the grooves should be such that the ratio of surface area of resilient material to metal surface area should be in the range of 1 to 2. The resilient material filled into the grooves is preferably rubber with a hardness in the range of 40 to- 70. The rubber strips must be at least flush with the hardened surface of the drum, and if they project above the surface the projection should be no greater than A; inch above the surface. A slight projection is preferred. The grooves should have a depth of at least & and the ratio of width to depth of the rubber strips should be in the range of from 2 to 1 m3 to 1.
In operation the roll 10 will be wound with the travelling web. Air, which tends to be captured in the nip N formed by the drum 12 and the roll 10, is expelled by the action of the resilient material in the grooves and the area between the grooves. The friction differential provided by the hardened metal areas 15 and the rubber strips 16 acts in a normal spreading pattern.
Thus it will be seen that I have provided an improved winder arrangement which meets the objectives and advantages above set forth and can be embodied in existing winders or in new construction.
The drawings and specification present a detailed disclosure of the preferred embodiments of the invention, and it is to be understood that the invention is not limited to the specific forms disclosed, but covers all modifications, changes and alternative constructions and methods falling within the scope of the principles taught by the invention.
