ABSTRACT:
Apparatus for supporting and tentering a flexible member on a layer of a gaseous medium. A support member has an array of passages which exit at a surface and which are arranged in at least two outwardly diverging rows which run obliquely to the path of travel of a flexible member. Channels are provided which run parallel to the rows of passages and each of which has a curved edge adjacent to the row of passages. The passages are oriented to emit gaseous medium in a direction having a component in the direction of travel of the flexible member, a component transverse to and outwardly to tenter the flexible member and a component perpendicular to the member. The gaseous medium is exhausted over the curved edges of the channels in a laminar flow.
