Abstract

1,012,534. Preparation of filtering medium. FLODINS INDUSTRI A.B. March 3, 1964, No. 8893/64. Heading BIT. Aerosol filters are made by placing a flat piece of filter material on a corrugated resilient foil-like support which is in turn supported on a planar surface, bringing the filter material and foil-like support into complete engagement, gathering the corrugations into a group, and removing the finished folded filter material from the foil-like support. The foil-like support is preferably polyethylene, although thin metal foil may be used. This method of folding reduces the chances of damaging glass fibre filters along their fold lines. The method is applicable to operation on multi-ply layers, and the final shape may be circular, oval, or ring- shaped, and is also applicable to filters having straight parallel corrugations. The resilient support 1 is placed on a table 5 and the filter material 2 pressed into engagement with it. It is then hand gathered against a peg 3 to assist the support 1 in re-asserting its corrugated form, and thereby corrugating the filter material. A retaining ring may be positioned round the filter material before removing it from the support 1. A roller may be used to press the filter material and support into engagement. The process may be mechanical, and the filter material may be sandwiched between two supports 1.
