, the work to a mangle. Heretofore it has been thepractice to use aprons inthe form of a single wide band, but it is found fdiliicult to force such an apron'to runstraight and true owing to uneven stretching or tension, with the result that the aprons weresoon worn out and constituted a heavy item of'ex-pense in the upkeep of'the machines. In some cases a number of narrow apron bands have been substituted for the single broad apron, these bands having been made in a strip and their-edges joined together. Such bands very soon tear atthe joint and are also an item of considerable expense.

It is the object of my invention tov produce an endless woven apron band.

Such a band is shown in the drawings,

I igure 1 being a general perspective view,

and Fig.2 is a transverse section on anenlarged scale to illustrate the relative thickness of the face and back of the belt.

As seen from the drawing the band made in accordance with my invention is of double thickness, the face being of heavy material, glving strength and wearing qualities, and

the back being of lighter material, giving stiffness and weight.

The method of manufacture is follows :''The tubular form is given in the weaving, and assuming that the band is to be 3 inches in width, 1 weave first an inch and a half strip of the lighter material for the back, then a three inch strip as A of the heavy material for the face, then a three inch strip of thelighter material, and then I alternate with three inch strips of heavy and Specification of Letters Patent.

These 1J inch strips as B are folded in against the underside of the facing", and the edges joined together and stitched through the facing as C. I also face and at each edge goods made in this I place a row of stitching 1 as D along the edges of the'band, these' stitches going through the face and the back. They stiffen and strengthen the web at the edges, and with the central row of securely unite the face and back of the band; The facing A being of the heavy material will standthc wear to which the surfaces of these bands'are subjected,

and the light back, while not subjected to the same kind of wear as the face, still gives strength and stiiiness'and body to the bands. The essential thing is that in this way I am able to produce a band which is endless and properly strengthened to give it a maximum of resisting qualities.

lVhile I- prefer to make the facing of heavier material than the back, still I do not wish to be understood as being limited to this precise construction,
