Title:
SKIR SPACING MEANS AND FORMATION THEREOF
Document Type and Number:
Japanese Patent JPS596916
Kind Code:
A
Abstract:
A pleated media filter element is disclosed which includes pleat spacers which are an integral structural part of the pleated media. The construction of the pleat spacers is accomplished by scoring on the unfolded media a continuous line pattern upon the portion of the media which, when folded, forms a pleat tip of the element. When the scored media is folded into pleats the patterns each define areas on the respective pleat tips which are integral structural parts of the media itself. The configuration of the pattern causes a portion of the media at the pleat tip to project transversely relative to the respective pleat, serving thereby as an integral spacer to space the pleat apart from the pleats on either side thereof.
