積重ねる台である。 The present invention will be explained in detail below. The continuous manufacturing method of the laminate of the present invention includes a plurality of long sheet base materials 1a,
1b...... are continuously transferred, and each sheet base material 1
a, 1b...... are separated from each other and passed through the thermosetting resin tank 3 to form each sheet base material 1a, 1.
After impregnating each of b with thermosetting resin,
A plurality of sheet base materials 1a, 1b...... are laminated by passing the plurality of sheet base materials 1a, 1b...... between the pair of upper and lower presser rolls 6, and the outermost sheet base material and the presser roll 6 are stacked together. A release sheet 7 is supplied in between, the release sheets 7 are stacked, and this is placed in a drying oven 2.
The laminated plate 9 is formed by continuous heating and pressing with multistage rolls 8, 8 arranged horizontally in a straight line in the drying oven 2, and then the release sheet 7 is peeled off and rolled. The laminate plate 9 is then cut to an appropriate size. Next, the present invention will be explained in more detail with reference to Examples. Sheet base material 1
a, 1b...... are kraft paper, titanium paper,
A long sheet of any fibrous material such as special paper, glass mat, nonwoven fabric, cloth, etc. is used, and these sheets are transported at a constant speed. These transferred sheet base materials 1a, 1b...... are first coated with any thermosetting resin liquid such as phenolic resin, unsaturated polyester resin, melamine resin, urea resin, epoxy resin, curable acrylic resin, resol resin, etc. Soak. In the figure, 3 is a tank for thermosetting resin liquid, and 4 is a scraper rod for squeezing out excess resin liquid. Note that four sheet base materials, 1a to 1d, are illustrated, but the number of sheets is arbitrary, and it is not necessary to impregnate each sheet base material with the same resin, and some sheet base materials may have different resins than others. It may also be impregnated with resin. When impregnating the resin, the sheet base material is impregnated with the resin by immersing it in the resin liquid tank 3 only once. Next impregnation, 2
Impregnation with the resin may be carried out in multiple steps, such as subsequent impregnation. 5 is a guide roll, and the sheet base materials 1a, 1b after being impregnated with resin are guided by the guide roll 5 and then between presser rolls 6, 6. At this time, a release sheet 7 such as silicon-treated paper is fed between the presser roll 6 and the front and back surfaces of the outermost sheet base materials 1a and 1d. After being stacked in this way, the sheet base materials 1a, 1b are led to, for example, a hot air drying oven 2 or a heating oven...
... is pressurized from above and below by multistage rolls 8, 8 in a furnace and heated with hot air to perform lamination molding. However, the number of multistage rolls 8 is arbitrary here, and in some cases, two rolls (two sets) may be sufficient. The degree of pressure applied by the multistage roll 8 may be such that a plurality of sheet base materials coated with resin can be bonded to each other, and in some cases, contact pressure may be applied, and in more extreme cases, the Sometimes the weight of the attached sheet base material is sufficient. Upon exiting the furnace, the release sheet 7 is peeled off and the laminate 9 is removed.
A long object is sent out, and cut into a fixed size using a cutter 10 to obtain a laminate 11. 12 is a conveyor for transporting the laminated plates 11, and 13 is a table for stacking a constant number of sheets.

質のよい積層板が得られるものである。 In the present invention, as described above, a plurality of long sheet base materials are continuously conveyed, each sheet base material is impregnated with a thermosetting resin, and then each sheet base material is placed in a drying oven. are introduced in layers and are continuously heated and pressurized using multistage rolls in a drying oven to form a laminate.
Since the laminate is cut, the sheet base material is continuously fed, impregnated with resin, and continuously formed using multi-stage rolls in a drying oven, producing laminates continuously at a constant speed. The impregnation, build-up, and molding processes, which were conventionally performed as separate independent processes, can be processed as a series of continuous processes. The production efficiency has been dramatically improved, and the build-up process, which conventionally required many people and was complicated, has been automated, saving labor. The mold sheets are piled up and heated and pressed continuously to form a laminate, and then the release sheet is peeled off and rolled up, so even when continuously molded with multi-stage rolls, the mold release property from the multi-stage rolls is good. Furthermore, since the sheet substrates are continuously transported and passed through a tank of thermosetting resin liquid at a distance from each other, multiple sheet substrates can be manufactured at the same time. Not only can the thermosetting resin be impregnated, but each sheet base material can be impregnated uniformly and sufficiently with the thermosetting resin to obtain a high-quality laminate. A plurality of sheet substrates impregnated with the same material are passed between a pair of upper and lower presser rolls to stack the plurality of sheet substrates, and a release sheet is supplied between the outermost sheet substrate and the presser roll. Since the release sheet is laminated, the release sheet can also be laminated at the same time using the presser roll that collects and laminates multiple sheet base materials, and the same presser roll can be used to stack the sheet base materials and the release sheet. Moreover, since the release sheet is laminated at the same time, the release sheet can prevent the thermosetting resin from adhering to the presser roll, allowing continuous operation, and it is also possible to dry multiple laminated sheet base materials. It is introduced into a drying oven and is continuously heated and pressed using multistage rolls arranged horizontally in a straight line in the drying oven to form a laminate. It is possible to obtain a high-quality laminate that can be used for printed circuit boards without warping, sheet base materials shifting from each other, or sheet base materials tearing.
