Application November 25, 1947, Serial No. 788,061

'l'he present invention relates to ironing rolls used to smooth or nish fabrics, and has particular reference to improvements in ironing roll coverings of the type including a lead cloth, Padding, and a cover cloth. n l

ironing roll covers conventionally include a lead cloth wound around an ironing roll'or cylinder, and a padding element of heavy fibrous material such as cotton or asbestos, tucked in under the terminal iiap of the lead cloth and wound around the roll to form one or more layers of padding. The cover cloth which may be of heavy cotton duck or other wear resistant material such as asbestos, is inserted under the terminal portion of the padding strip and wound once or twice around the, roller. The end of the cover cloth maybe allowed to flap loosely, or may be secured on the roller with a piece of tape or other material presenting a minimum of surface irregularity to the fabric to be ironed.

An ironing roll or cylinder may vary in length and diameter in accordance with particular work requirements. A standard heavy duty roll may vary from 100 to 120 inches in length, requiring a relatively wide vfabric strip for construction of the cover cloth. Under the extreme pressures of an ironing operation, the cover is pressed Out- Wardly from the center towards the ends of the roll, causing excessive strain and distortion of the center of the cover cloth. This factor necessitates frequent replacementrof cover cloths in order to maintain a uniform pressure surface.

It is an object of the present invention to overcome the aforementioned deficiencies, providing an ironing roll covering having a greater period of use. yet embodying a simple, economically constructed cover. j

A further object is Ito provide a cover for ironing rolls wherein the component parts are assembled as a unit which may be easily applied to the ironing roll by inexperienced personnel.

A further object is to. provide a cover cloth for ironing roll coverings which in operation maintains a smooth Apressure surface, compensating for the tendency of the cover cloth to expand laterally under ironing pressure.

- vOther objects and advantages of the invention will be apparent from the following detailed description thereof and the drawings, wherein:

Figure 1 is a perspective vieW of the ironing roll cover of the invention, broken away with the cover expanded to show constructional details; Figure 2 is a cross-sectional View of the cover in operating position on an ironing roll;

ment of cover cloth for use with the invention;

and

Figure 4 is a plan View of a further embodiment of the invention.

' In its broadest application, the invention provides a cover for an ironer including a lead cloth, a pad, and a cover cloth forming an extension of the lead cloth and including a plurality of fabric strips, overlapped at the edges to form a continuous pressing surface, the warp threads running longitudinally of the strips. The strips are so attached to the lead cloth as to converge inwardly upon the longitudinal axis of the cover cloth when not under pressure, the said strips being displaced outwardly by ironing pressures toy positions paralleling the axis of the cover cloth.

Referring to the drawings, the several gures disclose the invention as applied to a conventional ironing roll 1), the structures being broken away, shortening the normal width of theroll and cover for purposes of convenience of disclosure. The ironing roll cover includes a lead cloth II having secured along the length thereof a padding element l2. The lead cloth Il may be secured adhesively or otherwise at one end to the roll In, the other end I3 thereof being Iree.

As shown in Figure 1, a cover cloth I4 is secured to the free vend of the lead cloth, forming a longi tudinal extension thereof. The cover cloth I4 is shown as comprising two edge strips I5 and I6 and a central strip I1 secured vthereover so as to overlap the inner edges of the edge strips I5 and I6. The several members may be secured together as by stitching I8 and I9 or other means not shown, the invention not being limited in this respect.

y For purposes of strengthening the cover cloth I4, the strips are disposed with the warp threads running longitudinally of the strip in the direction of the arrow shown in Figure l, the ller threads running parallel to the aXis'of the roll. This 'arrangement has been found to minimize distortion of the cloth fibers under the application of pressure incident to an ironing operation,

` preserving a Smooth pressure surface, and mini mizes the effect of bowing of the filler threads frequently found in pieces of woven fabric, which condition tends to accelerate bunching and/or separation of the fibers.

In accordance with the invention, the cover cloth strips I5, I6 and l1 are so arranged as to compensate for lateral pressures exterted thereon during an ironing operation, tending to force the cover cloth towards the extremities of the roll I0. This is accomplished by securing the strips 3 I and I6 to the end I3 of the lead cloth I2 so that the strips normally converge inwardly upon the longitudinal axis of the cover cloth, when not under pressure, as shown in Figure 3. This normal inward bias of the strips I5 and I6 is stiffened or strengthened by stitching 2l) running lengthwise of the strips, anchoring the strips I5 and I5 to the end I3 of the lead cloth and also to the superimposed center strip I1. As pressure is applied to the ironing roll, the edge strips I5 and I6 are gradually displaced outwardly to a position approximating that shown by the dot-dash lines ZI in Figures 3 and 4, in parallel relation with the overlying center strip I1.

In Figure 4, the invention is disclosed in connection with a cover cloth I4 embodying two strips 22 and 23, sewn or otherwise secured to the end I3 of the lead cloth, and reinforced with onev or two rows of longitudinally extending stitching Z4. The strips 22 and 23 normally are biased inwardly towards the longitudinal axis of the cover cloth I4, operating under ironing pressure in the manner described in connection with the embodi ment of the invention shown in Figure 3.

The ironing roll cover of the invention may be employed with any type ironing roll such as for example chest and cylinder types, embodying a single ironing roll or a plurality of rolls. The standard type roll may be from 100 to 130 inches in length with a diameter of from six to fourteen inches. The ironing roll cover of the invention may be employed with the end of the cover cloth free, as shown in Figure 2, or may be secured around the roll with a flat tape member or string, not shown, to eliminate flapping of the cloth and to provide a minimum of distortion of the pressing surface. If the end of the cover cloth is to remain free, it is preferred to make the center strip II suiiciently long to overlap the ends of the strips I5 and I6, in order to eliminate flapping and improper placement of the edge strips I5 and I6 as the roll rotates, in the manner shown in Figure 3.

The lead cloth, padding and cover cloth may be manufactured of any mineral, animal or vegetable ber or mixtures thereof. For greater life of the cover, it is convenient to use asbestos fibers or fabric in making all components of the ironing roll cover. In some instances, it may be desirable to impregnate the cover cloth strips with a resin or plastic to increase the strength thereof and present a more regular pressing surface. Also, a glass fabric or a fabric embodying a glass constituent, may be employed in forming the elements of the cover.

An ironer cover constructed in accordance with the invention has the advantage of a markedly increased useful life, particularly with regard to the cover cloth. The cover is supplied to the trade in assembled form, eliminating the necessity for securing the services of experienced personnel maintain and assemble the parts of the cover. The ironing roll cover is of extremely simple, inexpensive construction, and may be used with any type ironer. It will be apparent that in application, the principles of the invention include the use of any number of strips in forming the cover cloth.

Other expedients within the scope of the invention and possible substitutions of equivalents will be apparent to one skilled in the art, and the invention is to be limited only as defined in the appended claims.

I claim:
