Abstract

809,739. Gas filters. POELMAN, A. J. J., and ETABLISSEMENTS R. SCHNEIDER. Oct. 23, 1957 [Oct. 24, 1956], No. 33086/57. Class 8(2). [Also in Group I] A sheet of paper 1, Fig. 3, is folded into parallel and uniform folds, and at least one side of the sheet is provided with streaks of adhesive, or threads coated with adhesive 2, after which the folds are closed up, whereupon the adhering threads 2 serve to space the folds and secure them (e.g. as described in Specification 763,917). Circular " cakes " of the sheet are cut out by a rotating, axially-movable cutter 4, Fig. 1, and the " cake " 6 is located between cheek-plates 8, 8a, Fig. 6, each having an annular reduced portion 10 or 10a, within a sleeve 9. A suspension of a plastic material having little tendency to contract on setting (e.g. poly-vinyl chloride) is then run into the space between 6 and 9 forming, when set, a mounting 7.
