  • Patent number: 7018493
    Abstract: A method produces a connection interface in a tubular filter element for filtering liquids, including a filter mat (10). The opposite ends (14) of the filter mat are interconnected in a connection position by a planar weld seam (28) provided with an embossed strip in the region of the free ends (14) of the filter mat. A region is provided between the embossed weld seam (30) and the beginning of the transition towards the tubular filter mats, in which a smooth weld seam (32) is applied without embossing in a flat strip along the ends (14) of the filter mat. This arrangement enables the ends of the filter mat to be welded together in a strong and long-lasting manner. The embossed weld seam is simultaneously unloaded of any stress by the smooth weld seam.

  • Patent number: 6936126
    Abstract: A drip irrigation hose of the continuous emitter type in which the outlets from the regulating passage each comprise a single longitudinal slit. By controlling the length of the slits and the flexibility of the film, water drips from the outlets when the hose is pressurized without clogging when the hose is depressurized. The slits are sufficiently long and the film is sufficiently flexible so the water drips from the outlets when the hose is pressurized. The slits are sufficiently short and the film is sufficiently rigid so the outlets close completely when the hose is depressurized. An outlet forming wheel has a knife blade on its periphery. A backing wheel engages the outlet forming wheel to establish a first nip therebetween. The backing wheel has on its periphery a circumferential slot into which the knife blade fits at the first nip. A rib forming wheel has around its periphery impressions that define a desired track pattern for the ribs.

  • Patent number: 6902639
    Abstract: A solvent-based adhesive is used to form a continuous, adhesively bonded and welded seam at the longitudinal edge portions of plastic film which have been overlapped. First, a bead of the adhesive is disposed on the edge portion of a web of film passing over an applicator roll. Next, as the film moves between the applicator roll and nip rolls, the adhesive dissolves a portion of the film to form a longitudinal channel having a generally semicircular cross-section. Then the edge portion is overlapped onto the other edge portion with the bead of adhesive between them. Finally the overlapped edge portions are squeezed between the nip rolls, so that the adhesive exudes laterally outward from the groove and is distributed smoothly between the overlapped edge portions, until the adhesive and dissolved film form a uniform band having a rounded hat-shaped cross-sectional profile.
