Patent ID: 6901639

Claim:
Stentering machine having a horizontal drying zone ( 3 ) for continuous treatment of a web of material ( 2 ) spread out between stentering chains ( 7 ) comprised of chain links ( 23 , 25 ), the two lengthwise edges of which are to be attached to the chain links ( 23 , 25 ) in a coupling zone ( 6 ), in releasable manner, wherein each of the chain links ( 23 ) possesses linking pins ( 22 ) that are to be coupled with an adjacent chain link ( 25 ), in each instance, in pivoting manner, the axes ( 32 ) of which stand essentially perpendicular to the plane of the web of material, and wherein guide rails ( 8 ), which are horizontal in the drying zone ( 3 ), having bearing roller tracks or glide tracks for the chains, are assigned to the stentering chains ( 7 ), wherein the linking pins ( 22 ) are configured as crowned elements, for a tilting angle between the chain links ( 23 , 25 ) that corresponds to a radius of curvature of a deflection zone ( 9 ), which is a 90° deflection zone ( 9 ) of the guide rails ( 8 ) arranged between a vertical coating unit ( 1 ) and the horizontal drying zone ( 3 ).
