' ROLL.

Patented June 1914.

Application filed June 17, 1909, Serial No. 502,732. Renewed February 7, 1913. Serial No. 746,923.

To all whom it may concern:

Be it known that I, HOWARD PARKER, a citizen of the United States, and a resident of Nashua, in the county of Hillsboro and State of New Hampshire, have invented certain new and useful Improvements in Rolls, of which the following is a specification.

This invention relates to improvements in rolls which may be used for various purposes, the roll illustrated in the drawings being designed for use as a couch roll in paper making and pulp treating machinery. These rolls usually comprise a rigid core and have a surface applied to them either of rubber, felt or. some such material.

In the drawingsFigure 1 is a side view partly in section of a roll embodying my inging a which are spaced at suitable intervals about the core and extend lengthwise thereof, giving the eflectof a longitudinally grooved core.- On top of this lagging I wind spirally a strip of felt I) on edge. I slit this strip to any desired depth but not sufiiciently to sever it, as indicated at c. In this slit I lay a binding wire d which binds the felt onto the core. At intervals I may use a smallstaple e which shall straddle the wire and be driven down into the lagging strips. This winding of felt is compacted endwise on the roll so as to give the roll a full and firm surface. If necessary the surface of the roll can be turned off to make it, smooth and of uniform diameter throughout. The slitting of the felt not only provides a means for binding it into place on the roll but also provides a water-way into which the water vwhich is pressed out of the pulp may escape and be led to the end of the roll; the water can also seep down between the strips and pass out through the troughs on the core formed by the lagging strips.

If desired in place of winding astrip of felt or like material onto the roll a single pieceof felt :1: having a width equal to the length of the roll maybe wrapped about the' shown in Fig. 5 it is desirable'to start the winding at the centerand have it run toward each end as in that caseit makes a shorter trelilvel for the water to get to the end of the ro I Still another modification is illustratedin Fig. 6, in which a strip of felt y is Wound spirally about the roll, the binding wire being laidalong the center of the strip and the strip being then folded up to present the edges of the strip to form the surface of the roll.

It is apparent that other materials than felt, for instance rubber, could be used in the same way and to the same advantage as is the felt. It is further apparent that the character of the core is not a material partof the'invention; it may be a solid core or hollow or of other construction.

I claim 1. A roll comprising a core, a covering wrapped about said core, a spirally arranged slit in said covering, and means lo-' cated in the bottom of said slit for securing said covering onto said core, substantially as described.

2. A roll comprising a core, a strip of covering material wound spirally about said core, said strip being slit for part of its depth, and means located in the bottom of said slit for securing. said covering to said core.

slits in said covering, a binding wire located in'the bottom of said slits for binding said cover onto said core, substantially as described.

4. A roll comprising a core, a covering wrapped about said core, spirally arranged slits in said covering, a binding'wire located in the bottom of said slits for binding said 3. A roll comprising a core, a covering wrapped about said core, spirally arranged.

cover onto said core, and staples straddling said wire and adapted to be driveninto sai core.

' 5. A roll comprising a core, a strip of covering material wound spirally about said core, and passages formed between said core and the bottom of said cover and extending lengthwise of said core.

'6. A roll comprising a core, lagging strips secured thereto and extending lengthwise thereof, and a strip of covering material wound spirally about said core on said lagging strips.

7 A roll comprising a core, lag 'ng strips secured thereto and extending fii ngthwise thereof, a strip of covering material wound spirally about said core on said lagging strips, said strip being slit for art of its depth, and means located in sai securing said covering material to said core.

8. A roll comprising a core, lag 'ng strips secured thereto and extending i ngthwise thereof, a strip of covering material wound spirally about said core on said lag 'ng strips, said strip being slit for part 0 its depth, a binding wire located in said slits, and staples straddling said binding wire and adapted to be driven into said lagging strips.
