  • Patent number: 11877645
    Abstract: A personal care implement that uses less plastic by removing material from a handle of the oral care implement while maintaining a comfortable grip which is similar to a normal grip that a user associates with a personal care implement. That is, the handle has a recess in a rear surface thereof, such that the handle or a portion thereof has a U-shaped transverse cross-sectional area. Portions of the handle may be covered with an elastomeric material to increase gripability and comfort. The handle may also include various rib structures elongated along the recess to increase the strength of the handle so that it does not significantly deform during normal use.

  • Patent number: 11724437
    Abstract: A bending method and a bending device, wherein a composite bar comprising a bundle of reinforcing fibres embedded in a polymer matrix is bent at a bending point. To make it bendable, the composite bar is heated locally at the bending point using an ultrasonic device with a sonotrode. After the bending point has been heated, an infeeding movement between the composite bar and the sonotrode is used to deform a region of the composite bar at the bending point to create a deformed portion of which the outer dimensions are different from the outer dimensions of the bar portions of the composite bar adjoining the bending point. The two bar portions are then moved or angled away in relation to one another, and so the composite bar is curved at the bending point. Once the desired bending has been achieved, the composite bar is cured at the bending point.

    Abstract: A coextrusion apparatus, a single-layer extrusion apparatus, a retrofit kit, as well as to a method for measuring a layer thickness, for producing a plastic film, and for retrofitting an extrusion apparatus. From the state of the art, it is known to add a detection agent in the form of a fluorescent granulate into the starting material at the extruder, in order to be able to measure the layer thickness of the layer in the film composite produced from this starting material. However, it is proposed to feed in a detection agent only beyond the extruder. This leads to a clearly shorter running time of the detection agent through the system and thereby to clearly faster measurability of changes in the production parameters.

  • Patent number: 7763197
    Abstract: A process for the production of a glass run channel is provided wherein the glass run channel has a S-shaped core of a polymeric material, onto which glass and/or frame sealing components are co-extruded. Preferably, a slip agent coating is applied shortly after the sealing components are added so that a completely polymeric glass run channel is produced in a single operation. The polymeric glass run channel is lighter, less expensive and more easily recycled than the prior art glass run channels.

  • Patent number: 7678316
    Abstract: A method that includes coextruding two or more thermoplastic resin streams through a profiled die plate, which die plate is shaped to form a nonplanar film (three dimensional) preferably with a regularly oscillating peak and valley structure that oscillates from a top surface to a bottom surface forming longitudinally extending ridges on both faces of the film. The film is formed by coextruding the film through the oscillating die plate opening causing partitioning of the resins in different zones in the width direction of the film. Flattening of the film results in a film with side-by-side zones formed of different polymers or relative proportions of polymers.

  • Patent number: 7678444
    Abstract: The present invention provides articles comprising a thermoformable composite comprising: a core comprising a renewable polymer having: (a) a Ts value of up to about 90° C.; and (b) a heat distortion index of up to about 90° C.; and a heat-resistant outer layer substantially surrounding the core and comprising a heat-resistant polymer having: (a) a Ts of greater than about 60° C.; and (b) a heat distortion index of greater than about 50° C.; wherein the renewable polymer comprises at least about 60% by weight of the composite, and wherein the heat-resistant polymer has a Ts value and heat distortion index greater than that of the renewable polymer. The present invention also provides methods for coextruding the heat-resistant polymer outer layer and renewable polymer core to provide a thermoformable composite.

  • Patent number: 7674412
    Abstract: The apparatus is for forming a resin film from a resin for a middle portion to form a resin film main body of the resin film and a resin for edge portions to form both side edge portions in a crosswise direction of the resin film. The apparatus comprises: a feed block which includes a joining part where the resin for the middle portion in a molten state and the resin for the edge portions in a molten state are joined in such a manner as to enclose both side edges in the crosswise direction of the resin film main body with the resin for the edge portions; and an extruding die through which the joined resins are extruded to form the resin film. Thus, a method and apparatus for forming the resin film can avoid the inclusion of the resin for the middle portion in the trimmed-off selvages while preventing the film separation of the resins for the middle portion and for the edge portions, and therefore, increase the recyclability and the productivity of the resin film.

  • Patent number: 7422711
    Abstract: A method of forming an extrusion comprises passing a first, plastics material (12) through a first channel (104) in a die, passing a second, plastics material (14) through a second channel (112) in the die, and passing a third, plastics material (16) through a third channel (314) in the die. At least one of the materials is passed through a metering gap into contact with the other materials to cause the at least one material to bond with the other materials as the materials pass through the die.

  • Patent number: 7258827
    Abstract: A method and apparatus for extruding unvulcanized rubber in a tire production process, in which an unvulcanized rubber extruded member can be formed by extrusion. An extruded rubber member having a cross section in which a portion of a second unvulcanized rubber intrudes between portions of a first unvulcanized rubber is formed by extrusion. The apparatus includes a first passage for the first unvulcanized rubber, a second passage for the second unvulcanized rubber, and a flow dividing mechanism where the first and second passages are adjacent or connected, which separates a portion of the first unvulcanized rubber passing through the first passage such that the first unvulcanized rubber is disposed at both sides of the intruded second unvulcanized rubber. In the method, the first unvulcanized rubber is divided into two flows, and a portion of the second unvulcanized rubber is caused to intrude therebetween.
