Abstract: Pleated filter medium and filters having pleated filter medium are provided. In one embodiment, a pleated filter medium is provided having pleats with rectangular sides and a length direction parallel to the fold between the two sides of a pleat. The pleated filter medium has several rows of distance elements extending in a cross direction relative to the folds in the pleated filter medium. The rows are distanced from each other along a length direction, whereby each row of distance elements is constituted of a line of glue elements distanced from each other and applied to a side of the filter medium. Rows of glue elements are applied to both the inside and the outside of the filter medium, the rows on the inside being displaced in the length direction in relation to the rows on the outside.

Abstract: The invention relates to a pleated filter medium (1) having pleats (2) with rectangular sides and a length direction (L) parallel to the fold between the two sides of a pleat (2), comprising several rows of distance elements extending in a cross direction (C) relative to the folds in the pleated filter medium, said rows being distanced from each other along a length direction (L), whereby each row of distance elements is constituted of a line of glue elements (3) distanced from each other and applied to a side of the filter medium. According to the invention rows of glue elements (3, 4) are applied to both the inside and the outside of the filter medium, the rows on the inside being displaced in the length direction in relation to the rows on the outside. The invention also relates to a filter including such a filter medium.
