PCT No. PCT/IT92/00114 Sec. 371 Date Apr. 13, 1995 Sec. 102(e) Date Apr. 13, 1995 PCT Filed Nov. 2, 1992 PCT Pub. No. WO94/10367 PCT Pub. Date May 11, 1994A device for feeding into and respectively withdrawing from an autoclave (1), of fabric (11) to be continuously decatized under pressure, together with a felt back cloth (3), includes in addition to the already known lead-in center cylinder (5) between the two runs of fabric going in and coming out (3, 11; 3', 11'), a pair of side cylinders (4, 6) cooperating with the above (5) and replacing the already known inflatable gaskets. It is the fabric-felt assembly (3, 11) itself that, by being compressed between the two pairs of cylinders (4, 5; 5, 6) builds a barrier against steam leakages. The center cylinder (5) and/or the two side cylinders (4, 6) may be recessed in order to define, in the nip area, a recess shallower that the thickness of the paired materials. In case all three cylinders (4, 5, 6) are smooth, the distance thereof will be suitably controlled for said purpose, and in both nip areas antifriction material pads (13, 13'), such as teflon, are preferably provided, in order to seal, at both ends of the cylinders, the gaps existing between the end of the felt and the side support members (15) of said cylinders.
