My invention relates to a resilient cushion or padding material and to means and mode of applying such material to rollers. While the invention will be described, for illustrative purposes, in its application to 'rolls of laundry ironing and pressing machines it is to be understood that the padding material is applicable to a wide variety of other purposes and shapes other than cylindrical rolls. Furthermore, the application of the padding to rolls is not limited to heated rolls but e'xtends to any general purpose cushion rolls. The material 1s also quite suitable for padding the bucks of steam pressing machines and may be'utilized' for other purposes than padding including filter-or strainer purposes and especially where a flexible heat-resistant material is desired.

' The heated rolls of laundry ironing or pressing machines are ordinarily covered with felt, cotton padding, or knitted cotton cord material which deteriorates very rapidly under the influence of heat. Furthermore such padding material soon becomes compact and loses its resiliency and cushion effect, necessitating frequent replacement.

The present padding materialconsists of a knitted blanket of metallic fibers known in the trade as steel wool. The metallic fibers are formed into a roving or rope with which are knitted a plurality of tie or warp wires, forming a resilient metallic fabric of uniform thickness, which is highly resilient and will not readily compact or become compressed, and'which will withstand heat of high degree without deterioration. In applying such resilient ad to a cylindrical roll it is combined with a binder cloth which may be canvas or duck'and for rollers subjected to very high degrees of 1 temperature, such binder cloth may be ofwire gauze or woven wire screen. The end of such binder cloth is secured to the surface oi; the roller and one or more preliminary turns of the cloth are a plied about the roller, and during the succee ing turn the binder 'cloth and metallic pad are wound together about the cylinder: The resilient metallic pad is cut to such size and proportion thatit will exactly agree with the cylindrical surface of the roller to be covered with its opposite margins abutting upon each other. Exteriorly of such metallic pad one or more final convolutions of the binder cloth are applied and the end of the cloth is secured to the underlying turn by stitching. It

A further object of the invention is to provide improved means for applying such afore described metallic fibrous padding material to the surface of cylindrical rolls.

A further object of the invention is to pro vide an improved method of forming metallic fibers into a blanket or'pad of uniform thickness and capable of indefinitely retain ing its shape.

With the above primary and other incidental objects in View, as will more fully appear in the specification, the invention consists of the features of construction, the parts and combinations thereof, and the mode of operation, or their equivalents as hereinafter described and set forth in the claims. Referring to the accompanying drawings wherein are shown the preferred, but obviously not necessarily, the only form of embodiment of the invention, Fig. 1 is a detail sectional View of a portion of an industrial laundry ironing machine, showing a succession of rollers to which the present form of padding has been applied. Fig. 2 is a fragmentary view of a domestic ironing or pressing machine to the roller of which the present padding is applicable. Fig. 3 is a detail perspective view of a portion of a roller prior tothe application of the padding material showing the tines or barbs by which the initial end of the binder cloth is secured. Fig. 4 is a perspective View of a portion of padding material and binder cloth assembled relative to each other preparatory to application to a roller. Fig. 5 is a sectional perspective view of a roller with the padding material applied. Fig. 6 is a detail perspective View of a fragmentary portion of the metallic knitted padding or cushion material. Fig. 7 is a further detail view thereof.

Like parts are indicated by similar characters ofreference throughout the several views.

The cushion or padding material in the present case consists of a pad or blanket 1 formed from metallic fibers, known generally in the trade as steel wool. While steel wire is the usual material from which such fibers are removed, wherefore it receives its designation as steel wool, it is to be understood that to meet special conditions of usage other metals may be employed. The metallic fibers which are of fine hair like character, are removed from the wirestock by a succession of cutting or scraping tools, which produce such fibers as fine continuous, or substantially continuous shavings. These fibers-from the several cutters are brought together to form a strand or roving of suitable size. This strand or roving is usually quite loosely assembled to an approximate diameter of one inch. The, strand or rope may be loosely twisted upon itself, but ordinarily, a light strandor cotton cord is wound helically about.

the assembled strand or roving in rather widely spaced convolutions suflicient to hold the assembled fibers together temporarily, until incorporated in the padding fabric.

The assembled strand or rope of metallic fibers which flow continuously from the fiber forming apparatus is conducted througha knitting machine or analogous apparatus in which the padding material is fabricated. Reversely disposed parallel portions of the roving of metallic fiber are interconnected and inter-tied one with another by a plurality of spaced wires of small diameter, which by the action of the knitting machines, are

' interlocked or looped one about the other intermediate each transverse roving of the fibrous metallic material. Fragmentary views of the completed material are shown in Figs. 6 and 7. This metallic wool fabric is produced in continuous runs of any desired width and is ordinarily one-half inch in thickness, although it may be produced of different thickness by varying the size of the strand or rope of fibers. The metallic fabric thus produced is subsequently cut to various sizes and shapes for use as cushions or padding material for various purposes. In its application to a roller, such as a laundry ironing machine roller, a portion of the material is cut to the size equivalent to the surface area of the roller to be covered.

This padding unit 1 is then secured by stitching or otherwiseto a strip of binder cloth 2 of greater length than the padding 1. This binder cloth extends in opposite direction beyond the margin of the metallic pad 1. For laundry ironing machines purposes, whether of industrial or domestic type, the binding cloth 2 is preferably light canvas or duck or any other suitable textile fabric. In the event that the roller is to be subjected to extremely high degree of heat the binder cloth 2 may be wire gauze or woven wire screen. The binder cloth 2 is sufficiently long to afford one or more initial turns about the cylinder or roller in advance of the metallic wool pad 1, and to afford subsequent to the application'of the pad 1 a few additional external turns of the binder cloth. The initial end of the binder cloth 2 is secured to the cylinder 3 by any suitable means. A

convenient and suitable means of attachment roller 3 through at least two preliminary turns. The metallic wool pad 1 is attached to the binder cloth in such relation to its end that sufficient length of binder cloth is afforded for the predetermined number of turns. Upon continued winding of the cloth 2 the pad 1 is wound-through one complete rotation of the roller, together with the next succeeding turn of the cloth. preferably cut to such size that its opposite margins will meet or abut at the completion of the single turn of such pad. However, it isobvious that if the pad is made of less thickness, two or more turns of the metallic wool pad 1 may be made about the cylinder. Following the winding of the metallic pad 1 about the cylinder additional turns, preferably two or more are made with the remaining end of the binder cloth 2. This serves to 6, which have polished surfaces over which the garments to be ironed are passed beneath the padded rollers 5. Inasmuch as the rollers are in direct contact with the heated surfaces intermediate the passages of the gar- The pad 1 is ments, the padding material is subjected to high temperature. The metallic wool padding will withstand such high temperature without deterioration. A similar condition exists in domestic ironing machines as illussuch fibers are relatively strong and especially resilient," metallic wool is also made from other metals including copper, lead, aluminum, bronze, brass and nickel. It is also produced in various grades or degrees of fineness. Thus knit metallic padding or cushion material may be produced to meet a very wide range of conditions and different.

usage.

While theknitting operation will produce the usual selvage on the margins, it is desirable to bind the edges, particularly the cut margins formed by separating the pad from the knit stock material. The binding material ispreferably wire gauze of thin closely woven Wire fabric, which is wire stitched upon the padding as indicated at 9.

While the metallic fabric, forming the subject matter hereof, has been described, for illustrative purposes, in its application to roll padding, it is to be understood'that it is not limited to such use but may be applied to other purposes wherein a flexible heat-resistant fabric may be desired.

From the above description it will be apparent that there is thus provided a construction of the character described, possessing the particular features of advantage before enumerated as desirable, but which obviously is susceptible of modification in its form, proportions, and arrangement of parts, without departing from the principle involved or sacrificing any of its advantages.

While in order to comply with the statute the invention is described in language more or less specific as to structural features, it is to be understood that the invention is not limited to the specific details shown, but that the means and construction herein disclosed comprise the preferred form of several modes of putting the invention into effect, and the invention is therefore claimed in any of its forms or modifications within the legitimate and valid scope of the appended claims.

Having thus described my invention, I claim:

1. A padding for rolls wherein the padding material is secured upon the roll by a winding of cloth enclosing the body of padding material characterized by a layer of metallic wool fibers interposed between successive turns of the cloth winding and interknitted tie strands uniting the body of metallic wool into a compact form.

2. Padding material consisting of a.

knitted fabric including a succession of parallel rovings formed of elongated massed metallic fibers and a plurality of transversely disposed metallic wires knitted about such rovings.

3. A metallic fabric consisting of a body of metallic wool into which are interknitted with each other a plurality of wire strands to form an elastic metallic fabric.

4. A metallic fabric comprising a knit metallic fabric consisting of a body of metallic wool into which are knitted a plurality of metallic wire strands,- said metallic wire strands being formed into successions of interlocking loops enclosing portions of the metallic wool.

5. A metallic fabric comprising a plurality of wire strands and a succession of. parallel rovings of metallic wool fibers, the wire strands being interknit about the metallic rovings into a fabric of substantially uniform thickness.
