A method and a device for cutting along a cutting line of a laminate (1), including a first (5) and a second (8) textile layer surrounding an intermediate layer (6) of a porous elastic material. The laminate (1) is pressed together in a local nip (2) between an ultrasound emitting element (3) and a counteracting element (4), and the laminate (1) is moved in the cutting line through and passed the nip during ultrasound cutting of the laminate (1) simultaneous with ultrasound welding of the first and the second surface layers to each other in order to form a smooth, rounded, continuous edge joint (11) between the surface layers at a free edge (10) of the laminate. The invention concerns also a cut product. |

The present invention provides, among other things, a new pipe insulation system that includes a reinforced, elastic foam lap seal closure system that can maintain the integrity of the protective closure around a pipe to be insulated, and can minimize seal failures. One aspect of this invention is the novel closure system that combines a seam seal vapor barrier with a reinforced elastic foam lap seal which bolsters seal integrity and helps prevents seam closure failure. |

Method for bonding a layer of thermoplastic polymer to the surface of an elastomer. A foamed elastomer having, preferably, an open-pore surface is used. The thermoplastic layer is pressed against this surface while it is heated by heat radiation, in particular laser light. The thermoplastic layer is transparent to this radiation, whereas it is they are absorbed by the surface of the elastomer. |

A method for evaluating rubber is provided which can evaluate the degree of crosslinking of a crosslinked rubber product within a short period of time without performing any specific treatment. In the above method, the amount of energy shift of the peak (such as the peak of C12p3/2 of chlorinated butyl rubber) of a constituent element of the rubber is measured by photoelectron spectroscopy, and the degree of crosslinking of the rubber is evaluated from the amount of energy shift. In addition, a method for manufacturing a rubber product is also provided which includes the steps of measuring the amount of energy shift of the peak of a constituent element of the rubber product by a photoelectron spectrometer which is installed in a manufacturing line and then feeding back measurement result to adjust heat molding conditions so as to obtain a desired degree of crosslinking. |

A method of making a molded article from two or more different formable materials having different molding temperatures in a single heating or molding cycle. One of the formable materials is selected as a reference material, and the remaining formable materials are modified so that all of the formable materials reach their respective molding temperatures at substantially the same time. Preferably, each of the remaining formable materials is modified by mixing a suitable amount of an additive therewith so as to adjust the power factor of the formable material. All of the formable materials are then placed in a flow molding apparatus whereby an alternating dielectric field is applied across the formable materials to form the molded article. |

An improved seal or boot for inhibiting contaminants from interfering with operation of a mechanism having two flexibly interconnected components which axially extend from opposite ends of the seal. The seal is formed as a one-piece hollow and elongated body defining an enclosed cavity wherein the pivotal connection of the mechanism is arranged and having first and second annular mounting ends. The first and second annular mounting ends are configured to allow the components of the mechanism protected by the seal to axially extend therefrom. To permit flexural movement of the seal and the interconnected components of the mechanism protected by the seal, a plurality of bellow-like configurations are disposed along a major length of the seal between the first and second mounting ends. Each bellow-like configuration on the seal has predetermined root and crest diameters with wall sections of a predetermined material thickness extending therebetween. To facilitate economic manufacture of the seal, the elongated body is formed from a cost efficient non-blow mold grade thermoplastic polyester elastomer. Forming the seal from a non-blow mold graded thermoplastic polyester elastomer furthermore enhances the durability and life of the seal. |

Devices for packaging and/or cushioning products and objects, the devices including permeable elastomeric sheets sealed together at predetermined locations to form separate and discrete chambers, or intercommunicating chambers, inflated initially with a gaseous medium comprising a gas other than air, oxygen or nitrogen which has a very low diffusion rate from each chamber through the elastomeric sheets, ambient air diffusing more readily through the sheets into each inflated chamber to provide a total pressure therein which is the sum of the partial pressure of the air in the chamber and the partial pressure of the gas in the chamber. Not only does the air diffusing into a chamber increase the total pressure therein above the initial inflation pressure of the gas, but the air in the chamber inhibits outward diffusion of the gas from the chamber or compensates for any loss of pressure caused by such outward diffusion of the gas. |

The opposed molded plastics shells of a shell covered foamfilled structural member suitable for boat hulls and decks are connected by a strip of material extending between the shells and anchored in the foam-filling. Flaps are provided on the connector strip overlying the periphery of the plastics shells in sealing relation therewith. The flaps can be provided on a separate strip with a tongue seated in a recess of the strip anchored in the foam. The connector strip has an outer edge portion secured in the parting line of molds carrying the shells and providing a cavity for the foam which is severed from the connector strip after removal from the molds.

POLYCHLOROPRENE RUBBER IS FORMED INTO A DESIRED SHAPE AND THEN TREATED WITH RADIATION HAVING A WAVELENGTH BETWEEN 2000 AND 35000 ANGSTROMS. THE RESULTING ARTICLE HAS AN EXTREMELY LOW COEFFICIENT OF FRICTION AT THE TREATED SURFACE BUT RETAINS ITS NORMAL FLEXIBILITY AND HARDNESS PROPERTIES. INCLUDING SMALL AMOUNTS OF SURFACTANT IN COMPOUNDING THE RUBBER PRODUCES A STILL LOWER FRICTION COEFFICIENT AFTER RADIATION.
