Abstract:
An automotive body delivered in a direction, and covers such as an engine hood and a trunk lid and doors of the automotive body are opened and held in an open position. Thereafter, prescribed areas of the automotive body are coated, and those doors which are located downstream with respect to the direction in which the automotive body is delivered and those areas of the automotive body which correspond to those doors which are located upstream with respect to the same direction, are coated. Thereafter, the covers and the doors of the automotive body are closed.
Abstract:
An instrument panel manufacturing system including a press forming device for the unit sheet and the core member having a feeding device and a heating device therefor.The feeding device (2) is provided with a suction device (20) for the unit sheet which is movable up and down, and the running rails (14) for the conveying bogie (21) are arranged between the sheet mounting position for the bogie and the conveying position so as to be movable up and down. The heating unit (3) is provided with lower rails (47) and upper rails (46) and includes a heater (48), and further a drying and melting device (101) having a drying chamber (102) and a melting chamber for the adhesive (65a) coated on the surface of the core member (65) is integrally arranged with the heating device (3). The forming device is provided with auxiliary rams (59) which are moved up and down separately from the lower die (55) and support the bogie running rails (61), the lower die (66) can be moved along the rails (223, 233) on the base block (49, 219) and an item expelling block (68, 232), and further the item expelling block (68, 232) can be inclined.
Abstract:
In a method for producing a plastic foam of a desired expanded dimension which is constituted by extruding a melt of a thermoplastic synthetic resin containing a blowing agent through a die of an extruder and passing the extrudate through a shaping device located outwardly of the extruder and secured to the discharge end of the extruder while expanding and solidifying the molten mass so that it fills the shaping device; the improvement wherein at least a part of that area of the inside surface of the shaping device with which the expanded resin makes contact is formed of a plate of a fluorocarbon resin, said plate being secured to the inside surface of the shaping device by fitting portions, said fitting portions having a sufficient space for absorbing an increase in the volume of the fluorocarbon resin plate at the temperature of extrusion molding; and an apparatus for use in the above described process.
