Abstract

1411772 Drying of webs BELOIT CORP 7 Nov 1972 [17 Dec 1971] 51382/72 Heading F4G A paper web W is supported in its sinuous path around heated dryer drums 12-15 and 16-18 etc. by means of one or other of two pervious endless felts 20 and 21, the web W being transferred from one felt to the other at guide rollers 24-28, the arrangement of guide rollers 24-28 being such that air entrained with the web W at A is removed from between the web W and upper felt 20 by sub-atmospheric pressure created at B, so as to prevent flutter of the web W in the run 20a. Similar effects are produced at C and D. Air entrained at 21a with the lower surface of the lower felt 21 positively pressurizes the space 36 causing air to flow through the lower felt 21 into the pocket 30 so as to assist in separating the web W from the lower felt 21 and hold the web W against the upper felt 20 in the run 20a. Moisture-laden air is removed from the ends of the pockets 30-33 by conduits 30a-33a. The guide rollers 24-28 (e.g. 25) may be suction rollers and each comprise a perforated shell and a movable suction baffle, for removing air from A-D. The air passing through the felts may dry the felts completely, but other felt dryers may be provided. The felts are guided and tensioned by rollers (not shown), and felt cleaners may be provided.
