Abstract
The covers are provided with additional elastic elements which act in the longitudinal direction of the cover connecting points opposite each other in the area of the edge of the short sides, in the longitudinal direction of the board, in such a way that the forces exercised by the additional elastic elements in opposing directions among themselves have values the sum of which is greater than the sum of the transverse forces exercised by the edge of the cover.

The present invention is designed to solve these said disadvanta9es, introducin~ rllearls thl-ough ~ihich the ironing board covers can obtain an easy and effective tensionil-g at the sarne time long-]asting, perl-nitting usage of the cover in opl:imum conditions of 3pplic~tioll on the ironing board llntil the rnaterial of tl~e cover is worn ollt lhrollc3h the repeated at-tion of the fL-icl:irn pr~dllr~d in tl~e ironint-~ .

Norrnally this in ernal foam layer is made of a laminate elelnent of a foam lype on the basis of a .synthetic material. The cover presents a broa;d cpening limiteti by the border -~;- whicll allows it to be fitted to the ircning board, havin~ a resistant corl trl3~tion all round the border which allows its retentioll orl the board.
As has been ~sketche(i in figures 8 and 9, the elastic of any cover which border~s a]l round the material of the cover and is stitched or ~oined or introduced into a hem or attached to it by any other sy.stelll, has an elongation limite~ o t:he l.el~tll of tll? perirnete~ f l:hr? cov-?r, since the co~/er is composed of a no~ e1a.sti.~ fabri.c.
