摘要:
Le système de drapage de bandes de matériau composite (3) comprend, outre une tête de déroulement (20), un ensemble original composé d'une source lumineuse (4) pour échauffer la bande (3) et durcir le composite et une paire de rouleaux (6a et 6b) appliquant la pression voulue pour assembler la bande à un stratifié (2) déjà déposé ou l'appliquer sur le support (1). Comme l'application de chaleur est concentrée à distance des rouleaux (6a et 6b) et avec une incidence perpendiculaire, ceux-ci peuvent être construits en matière élastique sans inconvénient, ce qui leur permet de bien s'adapter à la courbure transversale de l'outillage (1) de support et d'appliquer une pression uniforme.

A razor head (1) comprising a guard member (2), a blade unit (3) attached to said guard member (2), and an adapter (4) mateable with a razor handle, wherein said adapter (4) forms a cap member which is secured onto the guard member (2) on the same side as the blade unit (3).
摘要:
The invention relates to a method for sealing a fibre-based material (1, 4) to a counter-surface to be bonded to it by melting polymer present at the sealing point. In accordance with the invention, the sealing is performed by directing a laser beam (8) through the fibre layer (4) of the material to a radiation-absorbing pigment disposed in the sealing area (9), with the absorption heat melting the polymer (5) and generating the sealing. The method allows sealing of plastic-coated paper or board to itself, to another plastic counter-surface or also to paper or board without any plastic coating. It is also possible to seal uncoated paper or board to paper or board containing plastic, such as plastic-coated paper or board, or to a plastic film. The absorptive pigment, e.g. carbon black, may be admixed in the plastic coating of the board or paper or the plastic film formed on the counter-surface, or the pigment may be located on the surface of the material to be sealed or its fibre layer, or on the counter-surface to which the material is sealed, e.g. as a component of printing ink applied to the counter-surface.
摘要:
The invention relates to a container (1) comprising a mouth opening and a membrane lid (5) arranged with an attachment zone (6) on the edge of the mouth opening for closing the container, wherein the membrane lid consists at the attachment zone (6) over its thickness of plastic. The invention further relates to a method for producing such a container.
摘要:
A fuel injector is described that includes a polymeric housing, a metering assembly, and a closure assembly. The polymeric housing includes a continuous polymeric bore that extends from a first external seal proximate an inlet to a second external seal proximate an outlet of the bore along a longitudinal axis. The metering assembly is disposed proximate the second external seal. The closure assembly is disposed proximate the metering assembly, and a portion of the closure assembly is contiguous to the polymeric bore and disposed between the first and second external seals. A method of maintaining leak integrity is described
摘要:
A combination of resin materials which constitute a first resin member, a second resin member and a third resin member, respectively, wherein the first resin member and the second resin member are made of different materials, wherein the first resin member is non-absoptive for a laser light, and wherein the above members are used for laying the third member between the first one and the second one and subjected the three members to laser welding by the irradiation of the laser light from the first member side, to thereby weld the three members; and a method for the laser welding of those members. The above materials and method for laser welding allows, in the joining of resin members by a laser welding method, the satisfactory joining of resin members made of different materials having no or scarce adhesiveness with each other.
