板やプリント配線用基板として使用されている。A laminate made of paper, glass cloth, glass paper, etc. as a base material, laminated with a plurality of resin-impregnated base materials impregnated with a resin liquid, and then cured, and a metal foil on one or both sides of the cup laminate. Metal foil-clad laminates, which are made by laminating two metal foils together, are used as insulating plates and printed wiring boards.

５６−９８１３６号等参照。Conventionally, these laminates have been manufactured using a batch manufacturing method in which the base material is impregnated with a resin face, and the resulting burry rugs are layered and formed by pressurizing and heating in a press.
Recently, a continuous method has been developed that performs resin impregnation, lamination, curing, etc. while continuously conveying a long base material, and it is attracting attention. For example, see Japanese Unexamined Patent Publication Nos. 55-4838 and 56-98136 filed by the present applicant.

２７７５３号はそのような含浸および重ね合わせ装置を
記載している。In order to obtain a laminate of excellent quality by such a continuous process, it is necessary that the substrate be sufficiently impregnated with the resin liquid. In other words, the resin liquid must be supplied to the base material, and the supplied resin liquid must permeate into the interior of the base material and substantially completely fill the voids before being combined. Therefore, multiple base materials must be assembled immediately after the resin liquid is supplied. They are individually conveyed for a certain period of time without being combined, during which time the resin liquid is allowed to penetrate into the base material, and then they are combined. Applicant's Japanese Unexamined Patent Publication No. 57-
No. 27753 describes such an impregnating and overlapping device.

しい。However, the resin-impregnated base material, which is individually conveyed to the rolls of the resin liquid supply device during the required time for impregnation, does not have self-supporting properties, so it is necessary to support it with support rolls during conveyance.
Preferably, the substrate is turned along guide rolls in order to make a U- or V-shaped turn imparting a bending motion to the substrate, as proposed in No. 27753.

側縁の不整合等の不都合を生ずることが経験された。However, if the above-mentioned apparatus continues to be operated for a long period of time, the outside portion of the substrate may be damaged on the surface of the substrate conveyance roll, such as the support and/or guide roll, which comes into contact with the substrate before being transferred to the resin liquid supply device. It has been experienced that the impregnating resin liquid adheres and solidifies, causing unevenness on the roll plane, resulting in problems such as meandering and cutting of the substrate, and misalignment of the side edges of the substrate.
本発明はこのような不都合を解消することを目的とする
。The present invention aims to eliminate such inconveniences.

A plurality of elongated base materials 1 such as paper, glass cloth, glass paper, etc. are separated one by one in the vertical direction and conveyed in the direction of the arrow, and liquid resin liquid is supplied by a resin liquid supply device 2. . The base material supplied with the resin liquid is individually conveyed by support rolls 4, guide rolls 5, etc., and then transferred to a combination roll 3.
and then combined into a single-piece laminate. The laminate is then laminated with metal foil and/or a cover sheet on the top and bottom surfaces, and passed through a tunnel curing oven to become a product. Three substrates are used in the drawing, and each substrate has a V-shaped structure. Although it is shown that the substrate is conveyed so as to form the trajectory of the mold, the required number of substrates is determined depending on the thickness of each substrate and the thickness of the product, and the conveyance route also depends on the thickness of each substrate. is arbitrary as long as they are vertically separated. While each base material travels between the resin liquid supply device 2 and the combining roll 3, the support roll 4. When the resin liquid comes into contact with the guide roll 5 etc., a small amount of the resin liquid flows to the outside of the base material and adheres to the end of the roll, solidifies as time passes, and forms a convex part on the roll surface. , 5, etc. by supplying an impregnating resin liquid to the outer part of the base material and keeping the part constantly wet with the resin liquid, formation of resin lumps in the part is prevented. The resin liquid supplied to the rolls 4.5, etc. is collected into a pan or the like disposed below, and if necessary, solid matter can be removed by passing through the mouth, and then reused.
