Jan. 17, 1967 w. D. ANGSTADT ROVING CAN WITH REINFORCED TURNED FIBER TOP Filed March 31, 1966 INVENTOR.
WILLIAM D. ANGSTADT BY ATTORNEY United States Patent ROVING CAN WITH REINFORCED TURNED FIBER TOP William D. Angstadt, Norristown, Pa., assignor to The Budd Company, Philadelphia, Pa., a corporation of Pennsylvania Filed Mar. 31, 1966, Ser. No. 539,170 6 Claims. (Cl. 229-5.5)
This invention relates generally to containers and more particularly to roving cans or the like having a reinforced top open end, and which are particularly useful for textile rovings and slivers, and constitutes an improvement over my corresponding copending application, Ser. No. 516,486, filed Dec. 27, 1965, entitled Reinforced Container Rim.
As is known, roving cans are subjected to rough usage and must have sufiicient strength to withstand such usage. It is also known to form the bodies of roving cans of vulcanized fiber material or the like and to reinforce the upper and lower open ends by means of various reinforcing constructions, primarily of metal and secured to the can body in various ways.
Heretofore top rim reinforcing has also included such constructions as rolled fiber tops where a plurality of layers of fiber are rolled upon themselves to form the top; wire rings over which the body material has been turned have been used as also have rolled rims of various types and secured in various manners.
In my previous application the reinforcing rim member comprises a reinforcing band consisting of a single or double metal strip having the lateral ends rolled upon themselves, the upper rolled end extending over the upper end of the roving can body from the exterior into the interior of the can, and the lower end of the band was outwardly rolled upon itself to give added strength in the nature of a hollow rolled section. These constructions, however, had disadvantages when adapted for some usages in the textile weaving industry as well as in construction. The top of the roving can in these prior constructions had exposed metal at the top of the can and in textile mills, for example, were subject to corrosion from moisture or other elements in the air in the mill. The prior constructions also necessitated either riveting of the reinforcement to the counter body or a crimping proce- (lure of the reinforcing band and the material of the body, which constructions were time consuming, costly and provided impediments against free flow of roving from a can.
It is an object of the present invention to provide a top rim reinforcement construction for roving cans or the like where the drawbacks of the prior art are overcome and whereby highly improved construction and operational characteristics are obtained.
It is another object of the present invention to provide a top reinforcement for a roving can wherein the top of the can does not have metal exposed where it is contactable by roving being placed in or withdrawn from the can and wherein deterioration by contamination of the metal in this critical area is obviated.
It is a further object of the present invention to provide a roving can having a reinforced top construction wherein the fiber body of the can is so rolled over the reinforcing member as to eliminate static electricity conditions which result from friction between metal reinforcing rings and synthetic fiber materials of a nature now used in the textile industry.
It is a still further object of the present invention-to provide reinforcing means for the top of a roving can. of such a construction as to eliminate impediments, exposed rough or metal edges susceptible of corrosionetcQ, and in Patented Jan. 17, 1967 which no extraneous securing means, such as rivets or the like, are necessary.
The construction of the present invention is of such a nature, that the reinforcing ring or member is securely held in place by the material of the can, such as vulcanized fiber, and wherein the free end of the fiber container is secured in a tight and troublefree manner without the use of adhesives or the like.
Other advantages and features of the present invention will be more readily apparent from the following detailed description of embodiments thereof when taken together with the accompanying drawings in which:
FIG. 1 is a fragmentary sectional view of one form of the invention showing the reinforcing member is secured relation;
FIG. 2 is a view similar to FIG. 1 of a modification of the invention; and
FIG. 3 is a fragmentary sectional view of a seam construction utilizable for large diameter cans not susceptible of seamless construction.
Reference is now made in detail to the drawings showing the inventive concepts of the present invention and modified forms which can be utilized to this end.
As shown in FIG. 1, the can body 10, which can consist of vulcanized fiber or the like, is normally prefabricated as a seamless cylinder open at both ends. A bottom closure, not shown, is normally provided and the upper end is left open to provide access for placing roving material therein and/ or removing the same for subsequent weaving operations.
The upper end of the can, in accordance with the present invention, is provided with reinforcement means, generally designated 12, and normally consists of a metal reinforcing band or ring of a particular configuration. Generally, the band or ring is formed of strip metal in which the ends are brought together resulting in a circular hoop configuration and the abutting ends are welded or otherwise secured to one another.
In the specific embodiment shown in FIG. 1, the reinforcement means 12 consists of an inner band 14 and an outer band 16, preferably tack-welded together, as indicated at 18. The inner band 14 has its upper end rolled upon itself outwardly to form as closed loop 20 outwardly disposed from the exterior of the can body 10, and the lower flat portion 22 is juxtaposed to the exterior surface of the body 10 in proximity to the open top end thereof.
The outer band 16 is substantially identical with inner band 14 but having an upper flat portion 24 juxtaposed to the exterior of the flat portion 22 of inner band 14, as clearly shown in the drawing. A loop 26 is initially partially formed at the lower end of outer band 16 but left partially open for completion of the construction of the reinforced can upper end.
The material of the body 10 at its upper end is drawn above, rolled over and drawn downwardly over and beyond the loop 20 with its free end 28 inserted in the opening 30, which has been left in loop 26. Subsequently, by means of appropriate tools or dies the lower loop 26 is closed so that it crimps into the free end 28 of the material of the can body 10 in such a manner as As shown in'the drawings, the area between the loops .bands.
3 the material to continue to turn or roll. The substantial thickness between the loops, however, tends to downwardly deflect or direct the free end 28 of the material to facilitate its placement within the lower loop 26 and subsequent securement therein.
It is also to be noted in this embodiment and form of the invention that there is no exposed metal to the upper extremity of the can such, as for example, in my preceding application above referred to, and therefore problems of rust, corrosion, contamination, exposed rough edges, etc. of previous reinforcing band constructions are eliminated, as also the possibility of creation of static electricity.
The present invention, as above described, also overcomes drawbacks in previous attempts to form roving can tops having rolled over materials utilizing circular metal reinforcing rings or the like which tend to become displaced and/ or loose in the finished construction, and the present concept additionally avoids any tendency toward dislodgement of the free end of the turned-over body material or play of the reinforcement means.
In FIG. 2 of the drawings a further embodiment of the invention is shown which embodies the same principle and gives the same end result but in a different manner. Here the reinforcement means, generally indicated at 32, consists of a wedge-shaped metal band 34, having a thicker portion at the top and preferably rounded, as shown at 36. The lower end 38 of thinner dimension, is adapted to be formed into a loop similar to loop- 26 of the embodiment of FIG. 1 and has inserted therein, before closing of the loop, the free end of the material of the can body for subsequent securement and crimping as in the preceding embodiment. This configuration, as will be apparent, likewise provides a guide surface 40 to facilitate downward drawing of the free end 42 of the body material. The advantages of this construction are similar to those enumerated with respect to FIG. 1.
Other configurations of the reinforcement means will be apparent to those skilled in the art so long as they incorporate the fundamental principles of the above described examples and are intended to be included within the spirit and scope of the invention. Further embodiments, however, are not specifically described since this is considered unnecessary. It will be apparent that the described reinforcement constructions and the application thereof to roving cans will be much more effective in end result and in manufacture if the can body 10 is of a seamless construction so that no interruption in the surface thereof occurs.
Under some circumstances, however, where it is desirable to have a large diameter roving can or where shipment of flat sheet body material is desired for economy of space, handling, etc., it is some times necessary to join the ends of the sheet in formation of a cylindrical body. Lap joints or other types form obstructions to practice of the present invention and feathered edge joints are preferable to have continuity of inner and outer surfaces in a substantially uninterrupted manner. A completely feathered edge joint, however, is most difficult to form since the sealing pressure tends to slip the joint in assembly in addition to the difficulties encountered in generating feathered edges. It has also been found in such constructions that adhesive utilized in the joint tends to press out on both sides during cure under pressure.
A seam construction which overcomes these difiiculties is shown in FIG. 3 of the drawings, wherein the ends 42 and 44 of a sheet of material to be joined to form a cylinder consist of a double butt joint configuration, as appears in the drawings. Such a joint or splice provides full control of slippage and retards flow of adhesive during cure pressure while at the same time permitting adhesive to flow into the inside and outside butt joint and to pressure plates used in forming the joint thus filling the seam completely. Such a splice joint can be formed by machining the ends of the sheet on opposite sides and utilization of a proper adhesive and pressure to set and cure the adhesive.
Manifestly, minor changes in details of construction can be effected in the present invention without departing from the spirit and scope thereof, as defined in and limited solely by the appended claims.
