The laminate may sag and peel continuously, creating a gap between the laminate and the laminate. Once such a gap occurs, the laminate may lose its M' f:・P properties, or the resin may deteriorate. If it is unsaturated polyester, it will come into contact with air and cause problems such as insufficient curing.
本発明はこのような不都合全解消するため、硬化の初期

駆動装置を設けたことを特徴とする。The curing furnace of the present invention has an inlet and an outlet, where an uncured laminate consisting of a plurality of elongated resin-impregnated base materials combined and a cover sheet pasted on at least the lower surface thereof is received from the inlet, and the laminate is In a continuous curing furnace for laminates, in which the laminate is heated and hardened while leaving the outlet, a large number of laminates are used to continuously transport the laminate while supporting it horizontally within the curing furnace. The guide rolls are arranged at an angle of 1α with respect to the transport direction, and at least a plurality of guide rolls on the person [-] side are provided with a drive device for synchronously driving them. .
木発明を添付図面を参照してａ″６しく説明する。The invention will be described in detail with reference to the accompanying drawings.

れる。The drawing is a schematic diagram of the curing furnace of the wood invention, including the combined part of the impregnated base material and the laminated part of the laminated sheet. impregnated group ('A1 is the squeeze roll 3
, 3 and are combined. A cover sheet 9 such as a polyester film is laminated to the lower surface of the combined laminate using a laminating roll 4, and a metal foil or cover sheet 8 is similarly laminated to the other surface.
次に積層物は硬化炉５の人口１１から内部へ入り、出口
１２から出る間に加熱されて硬化し、そのゼ剥離ロール
１０によりカバーシート９が剥離さえて製品２となる。Next, the laminate enters the curing furnace 5 through the port 11 and is heated and hardened while exiting from the outlet 12, and the cover sheet 9 is peeled off by the peeling roll 10 to form the product 2.
上面にもカバーシートを張りぞわせた場合は同様に図示
しない剥離ロールで剥顯する。If a cover sheet is also applied to the top surface, it is similarly peeled off using a peeling roll (not shown).
硬化炉５内には適当な加熱源が設けられ、例兼が熱風が

うに駆動するのが好ましし・。The laminate is in an uncured state while passing through the guide roll 6 on the entrance side of the curing furnace 5, and the cover sheet [9] is easily peeled off. Therefore, the plurality of rolls 6 on the entrance side are each driven in a circular manner by a drive device (not shown). The drive device for this can be any known device, for example driven by individual motors, or driven by a common motor using a belt, chain, etc. Good. The rotational speed of the drive roll 6 must not be slower than the line speed of the board being conveyed by a laminate take-up device (not shown) after the laminate 1, and must not have excessive deviation. It is preferable to drive to give a circumferential speed that is the same as the line speed or 20% or less higher than the line speed.
