に大きな問題があつた。 Conventionally, such laminates are made by impregnating the base material with a varnish made by dissolving resin components in a solvent, then drying the solvent to create a prepreg, which is then cut to a certain size, stacked in multiple layers, and pressed in batches. It was manufactured using methods such as heating. In this conventional method, the prepreg must be non-adhesive due to workability and process constraints, which limits the resin components and requires the use of solvents, requiring a complicated manufacturing process. This caused a major problem in productivity.

た設備コスト高となつていた。 In view of the current situation, the present inventors have conducted extensive research into a method for continuously manufacturing laminates that has excellent advantages in terms of cost and productivity, and have arrived at the present invention. The present inventors have already reported in Japanese Patent Applications No. 54-35805, No. 55-1020, etc. that one or more sheet base materials are conveyed continuously and impregnated with a curable resin liquid, etc., if necessary. We have proposed a method for manufacturing laminates or metal foil-clad laminates in which the steps of laminating substrates, laminating metal foils or cover sheets, curing, and cutting to practical dimensions are performed continuously. In the method of the present invention, a strip-shaped resin liquid absorbing material is continuously inserted parallel to and close to the edge end of the impregnated base material,
Then, a metal foil or a cover sheet is laminated, and the excess resin liquid squeezed out at that time is absorbed into the band-shaped absorbent material. In the method disclosed in the above-mentioned Japanese Patent Application No. 54-35805 and Japanese Patent Application No. 55-1020, when laminating impregnated base materials and laminating metal foil or a cover sheet on the laminated impregnated base materials, the impregnated base materials Alternatively, excess resin liquid is squeezed out from the edge of the laminate. This is because, in the continuous manufacturing method described above, it is most important to prevent air bubbles from entering the laminate product. This is because when laminating impregnated base materials and further laminating a cover sheet or metal foil on the outer surface of the laminated impregnated base materials, it is desirable to squeeze out excess resin liquid from the impregnated base materials while preventing air from entering. . However, the excess resin liquid squeezed out in this way overflows from the edge of the laminate, stains the metal foil or cover sheet, and contaminates the receiving roll in the laminate curing oven. In order to prevent this situation, in the continuous manufacturing method described above, the width of the metal foil or cover sheet used is widened, and the width dimension is set to have enough margin to sufficiently hold the excess resin flowing out from the edge of the laminate. I needed it. Additionally, it is necessary to use a laminate with a correspondingly longer width, resulting in wasted materials and increased equipment costs.

ネートする際に余剰の樹脂液の外部への流出が防
止され、前述の欠点を解消することができる。 According to the present invention, if a strip-shaped resin liquid absorbing material is inserted close to the edge of a single impregnated base material or a laminate thereof, excess resin liquid can be removed when laminating metal foil or a cover sheet. The leakage to the outside is prevented, and the above-mentioned drawbacks can be solved.

燥機である。 FIG. 1 is a schematic diagram showing a preferred embodiment of the present invention. Single or multiple sheet-like base materials 1
is continuously impregnated with a curable resin in an impregnating bath 2. Thereafter, the impregnated base materials are laminated with the first squeeze roll 3 to form a laminate. The laminate then passes to a laminating roll 4 where it is coated with a metal foil or cover sheet 5
is laminated. At this time, excess resin flows out from the edge of the laminate, and a band-shaped absorbent material 6 is inserted parallel to the edge to absorb this excess resin. The strip of absorbent material is preferably inserted as close to and parallel to the ear ends of the laminate as possible. Next, the laminated plate 7 is heated and cured in a curing furnace 8, and the cover sheet is peeled off by a peeling roll 9 and wound onto a take-up reel 10. On the other hand, the obtained laminate or metal foil-covered laminate 7 is taken up by a take-up machine 11, cut into a predetermined size by a cutter 12,
This becomes product 13. When using a single base material 1, the first squeezing roll 3 is not necessary. Furthermore, even when a plurality of base materials 1 are used, the lamination of the impregnated base materials and the lamination of the metal foil or cover sheet may be performed simultaneously using the laminating roll 4. When trying to obtain a metal foil-clad laminate, it goes without saying that the laminated metal foil will not be peeled off by the peeling roll 9. Note that 14 is a dryer that dries the base material 1 if necessary.

The strip-shaped absorbent material 6 is stored on a reel and fed to the laminating roll 4 parallel to and close to the edge of the impregnated substrate 1 . The metal foil or cover sheet 5 is supplied to the laminating roll 4 so as to sandwich the laminate of the impregnated base material 1 and the strip-shaped absorbent material 6 from the outside, and is laminated. The excess resin liquid squeezed out at this time is absorbed by the absorbent material 6 and does not flow out to the outside. The reel for storing the strip-shaped absorbent material 6 is mounted on a shaft 18, which is connected to a position control drive device ( EPC) 17. The strip-shaped absorbent material 6 therefore acts as a sensor 16.
By moving the shaft 18 in the direction of the arrow in response to the position of the ear end detected by the EPIC 17, the EPIC 17 is automatically inserted into the correct insertion position. Note that 15 is a guide roll for the strip-shaped absorbent material 6. EPC17
may be of any conventionally known type, such as electrical, pneumatic, or hydraulic.
