    摘要: In the resin film forming method for extruding a fused resin from an extruder die to form a resin film, the second resin forming both ends in width direction of the resin film uses a resin greater in extension viscosity than the first resin forming the center in width direction of the resin film. Thereby, even if production conditions such as resin condition and operating conditions change, faults such as neck-in and its resultant thickening at both ends of the resin film can be suppressed. In the production of a laminate by nipping a support and a resin film of a thermoplastic resin by means of a nip roller and a cooling roller while coating the resin film onto the surface of the support, the accompanying air following the rotation of the cooling roller to the nip point is shut off by blowing a gas permeable through the resin film from a gas jet nozzle toward the surface of the cooling roller. Thereby, the occurrence of craters can be inhibited, a laminate excellent in surface appearance can be produced and the production of a laminate effective especially at the time of a line speed rise in the laminate production is performable.

    摘要: Method of coating a metallic substrate (1) with thermoplastic coating material, comprising a preheating the substrate in such as way that, just prior to coating, it is at a temperature between 70° C. and 150° C., preferably between 100° C. and 130° C. in the case of a coating containing polypropene and between 80 and 110° C. in the case of a coating containing polyethene; coextrusion, in the first coating station of a sheet (6) comprising a polyolefin covering layer and a modified polyolefin adhesion layer; coating of the substrate (1) with a molten sheet in the presence of ozone by pressing it with the adhesion layer against the surface of the substrate; transportation of the strip (9) coated on one side to a second coating station and heating the strip so that, just before coating, the strip is at a temperature between 70° C. and 130° C., preferably between 80° C. and 120° C., if the coating layer applied in the first coating station is polypropene and between 80 and 110° C. if the coating layer applied at that point is polyethene; coating of the substrate with a molten sheet extruded in the second coating station by pressing it against the uncoated surface of the substrate, use being made of the presence of ozone; heating of the coated substrate so that it assumes a temperature which is above the melting point of the polyolefins applied; cooling of the coated substrate.

    摘要: Rollers, substrates, products and the like are not smeared with a sticky volatile component when a gas is blown from a blower provided near an extruding die to produce laminates. The blower is heated by a heater at a temperature not below the volatilization temperature of the volatile component volatilized from a resin film of thermoplastic resin extruded in molten conditions from the extruding die, and therefore the volatile component cannot stick on the blower and is immediately volatilized on the blower.
