Textile cot assembly

A textile cot assembly comprising a rigid cylindrical core;

• a rigid tubular cylindrical supporting means fixed concentrically around said core and having a supporting surface adjoined at opposite edges thereof by a pair of annular shoulders of greater diameter than said surface;
• and an elastomeric sleeve having a tubular inside surface and a plurality of gripping projections extending radially inwardly from said inside surface with each projection having an inner portion engaging said supporting means, said sleeve being disposed in stretched condition with its diameter increased within the range of approximately 3 to 8 percent from its unstretched condition, the outer diameter of said sleeve, when stretched and seated, being greater than the outside diameter of said shoulders, said inner portions of said projections being partially deformed at their area of contact with said supporting means by radially inward pressure exerted by said stretched sleeve, said projections with their partially deformed inner portions preventing rotation of said sleeve relative to said supporting means.
