  • Patent number: 11123949
    Abstract: A textured laminate that contains a coform nonwoven web formed from a matrix of synthetic fibers and an absorbent material is provided. The coform web is positioned adjacent to a cellular film that includes a plurality of cavities encapsulating a gas (e.g., air). By selectively controlling various aspects of the coform web, film, and the particular manner in which the film and coform web are laminated together, the present inventors have discovered that the resulting laminate can achieve an increased bulk that remains relatively stable even in a wet condition. Thus, the resulting laminate can be readily employed in a wet wipe without losing its bulk and overall texture.

  • Patent number: 10647048
    Abstract: A method for tempering preforms in a blowing machine, wherein at least one heating box is arranged along a transport path for the preforms. The heating box has reflective walls and forms a heating channel through which the preforms are guided. The heating box also has a heater for heating the preforms in the heating channel, and a cooling device, having a blower, for cooling the reflective walls. The walls are cooled by a quantity of air flowing along the walls outside the heating channel. The heating output of the heater is adjustable. A control device provides open-loop and closed-loop control of the cooling output produced by the cooling device, in particular the supplied quantity of air, depending on the respective heating output of the heater, depending on a measurement of the heating output.

  • Publication number: 20110012295
    Abstract: A method of stretch-blow-moulding a beverage container for containing a carbonized beverage which method comprises providing a preform (11) having a neck part and a body part. The preform includes an inner layer (24) of a first polymeric composition, an outer layer (12) of a second polymeric composition, and an intermediate layer (22) of a third polymeric composition. The third polymeric composition has adhesive surface properties relative to the first and second polymeric compositions, and the adhesive surface properties are permanently degraded by exposure to irradiation of a certain wavelength or certain wavelengths and intensity. The method further comprises mounting the preform onto a stretch-blow-moulding device and blow moulding the preform into the beverage container by irradiating the body part with radiation at least including the certain wavelength or certain wavelengths and intensity while protecting the neck part from any substantial radiation.

  • Publication number: 20110006462
    Abstract: A method and/or system for forming a plastic bottle from a preform without the use of a mold or a complete mold are provided. The technique includes selectively injecting heat into the preform using narrowband irradiation devices emitting irradiation in a narrow wavelength band matching desired absorptive characteristics of selective portions of the preform according to a predetermined heat signature to achieve a three-dimensional heat profile in the preform. The heat profile corresponds to a desired shape of a finished bottle and facilitates self-limiting stretching of the selected portions of the preform to achieve the desired shape. Using the technique, air is selectively injected into the preform to form in free air the finished bottle having the desired shape.

  • Publication number: 20100295217
    Abstract: The invention discloses a method of heating a preform (50) of thermoplastic material prior to blow molding the same to form a container, with the preform (50) being held at a threaded region (58) during heating thereof. A neck portion (48) of the preform (50) close to the threaded region (58) is temporarily heated more strongly as compared to other regions. The invention further relates to a tempering device for heating such a preform (50), including at least one radiation and/or heat source acting on the preform (50) and defining several impact regions on the preform (50) with different heating intensities each. The preform (50) has associated therewith at least one reflector (52) disposed in the threaded (58) and/or neck region (48) for deflecting radiation proportions piercing the neck region (48) and for heating the neck region (48) on an inside of the preform (50).

  • Patent number: 7708928
    Abstract: Medical device balloons are formed from a tubular parison by a process or apparatus which establishes a controlled location (initiation zone) on the parison where radial expansion is initiated. Initiation within the initiation zone is achieved by heating the parison in that location to a higher temperature than the remainder of the parison for at least a portion of the blowing time. A variety of apparatus configurations are provided, some of which allow for the size and location of the initiation zone to be readily reconfigured. Balloons can also be modified, post-blowing, using heating apparatus and methods described.

  • Publication number: 20100007060
    Abstract: The process and the apparatus serve for the blow moulding of containers (2). A parison (1) composed of a thermoplastic material is first subjected to heat conditioning along a transport path in the region of a heating section (30). The parison is then subjected to a forming process within a blow mould with exposure to blowing pressure to give heat container. The heat conditioning of the parisons is carried out by a plurality of mutually superposed radiant heaters (41). The blow moulding of the container is followed by wall-thickness measurement at at least one level within the height of the container. The heating power of a radiant heater associated with this height level is controlled. The control system receives a prescribed wall-thickness value as required value and the measured wall thickness as actual value.
