This invention relates to sliver or roving drawing devices devised for the drawing effected by spinning frames, as also by preparatorymachine's and for drawin gframes. More particularly it relates ,to an improved drawing roll, especially effective for middle top rolls. t a
This application is a division of myU. S. patent for improvements in drawing devices forspinning frames and for preparatory ma-,
chinery No. 1,749,393, dated March 4, 1930, in
vwhich the greater efficiency of drawing rolls p having great resiliency and compressibllity or suppleness 1s set forth, and in which. is
claimed a deformable sleeve for drawing 7 rolls characterized by a hub and an outer skin with partitions forming .a number of hollow compartments therebetween. My present invention is" particularly con:
99 cerned with a form of sleeve or working memher for drawing rolls which is so constructed as to provide a single hollow compartment between the working member andlthe arbor which supports said member.' The single" hollow compartment is,'in effect, an air cush ion for supporting the working portion of the drawing roll, greatly increasing the suppleness and compressibility of the-roll over other forms while maintaining a uniform deiso gree of compressibility about its whole-cir-,
cumfer'ence and throughout its length.
The nature of my invention will be under-- .stood from the following description of the accompanying drawings in which:
Figure 1 is a cross-sectional view of the preferred construction of the drawing roll I,
sleeve; I v
Fig.- 2 is a cross-sectional View of a sl1ghtly modified form of the drawing roll sleeve Fig. 3 is a view, in perspective, of the sleeve before assembly on a metalarbor; and Figs. 4 and '5 illustrate, in longitudinal cross-section, two waysin which the sleeve may be mounted onan arbor.
The sleeve is a moulded product and pref erably is formed of soft rubber having a high degree of resiliency. The mould is formed" to produce a cylindrical'envelope having a comparatively thin circumferential or tubufacture of drawing rolls.

I also believe that I am thefirst to devise a drawing roll having. great suppleness due to a material longitudinally depressible thickness provided betweenthe metal arbor and the outer sheath or skin, a portion of said thickness comprismg a single annular chamber of air anda portioncomprising a flexible sleeve.
The drawing roll ofthis invention is particularly useful as a middle top roll but its use is not restricted thereto.
