Inventor: MICHAELIS UDO
IPC: F02M35/024
Filed: 1991-01-25
Abstract: A filter element made of non-woven fabric formed as a folded package is self-supporting and is composed of thermally sealable non-woven fabric (1). Each of the two outer edges (3) of the folded package (2) is lined by the non-woven fabric material (1) forming the folds (4), which material, at each folded edge (3), is folded over in the same direction and is fixed to the corresponding bent edge of the adjacent end of fold in a tight fitting manner. The non-woven fabric material overlaps each bent edge of the adjacent end of fold by 1.5 to 2.5 times the fold separation. 
<??>To produce the filter element, the flat filter medium (1) is first folded and then a defined fold separation (7) is produced by a limited stretching perpendicular to the folding. The two outer edges (8) of the folded package are then positively clamped into comb-like sections (9) corresponding to the geometry and dimensions of the folds, and penetrating pincer-like into the folds on the upper and lower sides, the filter material projecting over the shaped sections (9) on each side by 1.5 to 2.5 times the fold separation (7). The overlapping material (10) is folded down on both sides in each case by means of a first pressing element (11) having a sideways action thereon, until the overlapping material (10) fits on the adjacent end of fold, so that the edges overlap. Energy allowing thermal sealing is supplied via these pressing elements (11). Further subsequent pressing elements (12) fix the sealed sites during cooling. The comb-like sections (9) are then removed and the folded package is contracted.

Title: Dynamic stitching of inkjet heads
Inventor: KRASTEV OGNYAN
IPC: B41J2/00
Filed: 2018-04-13
Abstract: The dynamic “stitching” of inkjet heads relates exclusively to the design of printing machines, operating by the single-pass method (relative motion of the print media toward the inkjet heads in one direction only). The manufacturing of the main plates (fig. 1a, B), on which the inkjet heads are based (fig. 1a, A) and respectively of the boxes themselves for printing modules in a shape that allows their mutual penetration, allows two or more printing modules, located in one line toward the relative motion of the printing material toward the printheads, to be connected in one larger in order to get a continuous printed image with greater precision, without the need to increase the size of the machine for misalignment of the printing modules. This achieves print quality improvement due to reduction of the total distance of the heads arrangement in the direction of movement of the print media and hence - reducing the impact of speed fluctuations and improvement of the accuracy of the drops (dots) in the overall image. On the other hand, this leads to a reduction in the inkjet heads needed to cover standard printing areas today when printing in several columns (pages) or double-sided printing in one machine and therefore the overall dimensions of the machine, which due to the high cost of heads and others high-precision components, leads to a reduction in both the value of the machine and the operating costs.
