Abstract: A bagmaking and packaging machine packages articles with a film. The bagmaking and packaging machine includes a laser printing device and a receiving member. The laser printing device prints on a printed surface of the film. The receiving member is disposed so as to oppose a non-printed surface on the opposite side of the printed surface of the film. The receiving member has a reflection suppressing surface. The reflection suppressing surface suppresses regular reflection of laser light emitted by the laser printing device.

Abstract: A bagmaking and packaging apparatus includes a film supply unit that conveys a film, a printing unit, a speed detector, and a control unit. The printing unit applies laser light to the film to print the film. The speed detector acquires data relating to the conveyance speed of the film. The control unit links the operation of the printing unit when printing the film to the conveyance speed of the film based on the data from the speed detector.

Abstract: In a double-belt press, an inner seal has an inner seal flow passage having an intake port via which a sealing fluid supplied into an inner sealing groove is taken in and a jet port via which the sealing fluid taken in via the intake port jets toward belts. The outer seal has an outer seal flow passage having an intake port via which the sealing fluid supplied into an outer sealing groove is taken in and a jet port via which the sealing fluid taken in via the intake port jets toward the belts. The partition wall has a plurality of fluid supply passages that supply each of the inner sealing groove and the outer sealing groove with the sealing fluid and a plurality of fluid recovery passages that recover the sealing fluid accumulating in the space formed between the inner seal and the outer seal.

Abstract: A plastic laminated structure includes a plate member of plate-shaped fiber-reinforced plastic and a core member of trapezoidal-wave-shaped fiber-reinforced plastic. The plate member includes a thermoplastic resin and reinforcing fibers embedded in the thermoplastic resin. The core member is thermally bonded to the plate member, and includes a thermoplastic resin and reinforcing fibers that is embedded in the thermoplastic resin. A part of or the entire area of a main surface of the plate member includes smooth and rough surfaces. The rough surface has larger roughness than the smooth surface. The smooth and rough surfaces are alternately arranged in stripes.
