The invention i~ particularly of use when, in a way known per se, the profile wall ad~acent to t~e slit has been rounded off and has been slightly bent inward. In that case the weight of the curtain will be entirely on the rounded edges adjacent to the sl.it, thus on a small surface.
It has been ob6erved that also in that case a polyvinyl layer ~s highly abrasion-resl~tant and friction reducing.

A curtain rail is preferably provided with reinforcing - ~.
ribs. When, however, 9uch ribs come into contact with the : curtain hanging device~, this may easily lead to abrasion . 15 and thereafter to increas~ng friction. In applying the invention this disadvantage is reduced to a high degree.
further embodiment of the invention accordingly provides that the profile has inward stick~ng ribs acro~s the slit that are positioned in the wldth direction beside the slit.

In practice this can be effected by hanging the rail lengthwise in a deep container fllled with liquid thermoplastic 6ynth~tic materIal and 6ub~equently by withdrawing it relatively 510wly. The part that has ~ust left the liquid is sti.ll warm and is therefore capable of ~ :
dripping dry ~atlsfActorily. When the entire rail has been Ilifted out of the liquid, only the bottom part is left to 35 drip dry, wherea~ the upper part has already cooled down. m- -~...
A rail thus coated wit~ polyvlnyl chloride has a layer of ~aid synthetic material that ls 80 thin (in quantities of .:~
tenths of millimetres) that little material i5 used, which ':
r~- ~ 2 ~ 1~ 2 1 ~ 7 limlts the cost aB well. These cost are certainly low compared to the cost of the finishlng procesB ~ which i~
us~ally carried out prlor to Applying the ~o~ ln accordance with the invention. For a rail made of alu~inum -the finishing consi6ts of hardening the str~ngpressed rail, degreasing it, chromatizing it ~s a protection again6t oxidation and to prevent depo61t in moist surroundings, applying a powder coating at the inside and outside of the rail by ~eans of electroetatic spraying and muffling it.
Such a ~uffled layer may be smooth, but considerably less 80 than, for instance, a layer of~polyvinyl chloride. -~
The invention will hereinafter be further explained, -reference being ~ade tot t~e drawing where: -fig. 1 shows a cross section of a curtain rail according to the invention; and fig. 2 schematically showc the layering structure thereof.
In fig. 1 a cross section of a curtain r~il is shown with a body 1 and upright legs 2. The legs are bent inward at their ends and thus form f langes 3 which have a bending and thlckening 4 at their endc ad~acent to the sl$t 8, which form supporting ridges 5 at the inside of the profile.
Reinforcing ribs 6 reinforce the body 1, in which case it 25 is irrelevant whether they come lnto contact with runners ~ ~
or ~liding devices that are not drawn, because said ribs ~ -are coated with a protecting, friction reducing ~ayer. The thlckenings 7 between the body 1 and the legs 2 likewise serve a~ r~inforce~ent.

In fig. 2 the aluminum of the rail is lndicated by 9, the chromatized ~ilm by 10, the muffled layer by 11 and the layer according to the invention by 12. For the sake of clarity lo and 12 are proportionally drawn too wide.
