The step of driving the cloth along the length direction of the splice 100 using the squeegee includes: the effective cloth scraping width of the scraper is consistent with the groove width of the limiting groove 430, and the scraper is used for driving the guide cloth 200 adhered to the splice body 100 along the length direction of the limiting groove 430. When the device is used, the plurality of pultruded panels 110 can be arranged in the fixing tool 400, then the first limiting arm 410 and the second limiting arm 420 are used for respectively clamping two sides of the width direction of the splice body 100, as shown in fig. 4 and 5, the first limiting arm 410 and the second limiting arm 420 both extend along the length direction of the splice body 100, the first limiting arm 410 and the second limiting arm 420 both protrude towards one side of the first plate surface of the splice body 100, a strip-shaped limiting groove 430 extending along the length direction of the splice plate is formed between the first limiting arm 410 and the second limiting arm 420, and two side walls of the limiting groove 430 are consistent with two side walls of the width direction of the splice body 100; the effective width of scraping cloth of scraper blade is unanimous with spacing groove 430's groove width, the scraper blade stretches out in spacing groove 430 promptly, the both ends of scraper blade respectively with the both sides cell wall contact of spacing groove 430, then the operation scraper blade is scraped to the other end from spacing groove 430 length direction's one end, thereby realize that the scraper blade once only catches up with cloth to diversion cloth 200's comprehensive along length direction, on the basis of guaranteeing to catch up out the comprehensiveness to the bubble, further improve the uniformity of catching up with cloth back bond coat 300 thickness, the corresponding comprehensive fastness that improves bond coat 300 and paste diversion cloth 200, and improve the uniformity of the whole thickness of panel goods 10. Specifically, the width of the scraping plate may be greater than or equal to the groove width of the limiting groove 430, and when the width of the scraping plate is greater than the groove width of the limiting groove 430, the scraping plate is obliquely inserted into the limiting groove 430, and the effective cloth scraping width of the scraping plate is smaller than the actual width of the scraping plate; preferably, the width of the scraper is equal to the width of the limiting groove 430, so that the scraper is approximately vertically inserted into the limiting groove 430, and each part of the scraper can synchronously catch up the guide cloth 200.

Alternatively, in the splice 100, the gap between two adjacent pultruded panels 110 may be 0mm to 5 mm. When the fixing tool 400 is used for clamping and fixing the splicing body 100, the pultrusion plates 110 are in a compression state, the gap between two adjacent pultrusion plates 110 is approximately 0mm, the thickness of the pultrusion plates 110 is limited after the flow guide cloth 200 is adhered to the first plate surface of the splicing body 100, and the pultrusion plates 110 can be bent and deformed only at the joint part towards one side where the flow guide cloth 200 is located, so that when the bottom surface of the mold is an outward convex cambered surface, the flow guide cloth 200 of the first layer of plate product 10 faces the bottom surface of the mold, and the pultrusion plates 110 of the layer plate product 10 can be bent and deformed towards the bottom surface to enable the flow guide cloth 200 to be adhered to the bottom surface of the mold; and then, other layers of plate products 10 are also stacked and arranged on the first layer of plate products 10 in the direction that the flow guide cloth 200 faces the bottom surface of the mold, so that the stacked and arranged layers of plate products 10 are arranged on the bottom surface of the mold. When the bottom surface of the mold is an inwardly concave arc surface, the splice 100 of the first layer of sheet material product 10 can be oriented toward the bottom surface of the mold, and the pultrusion plate 110 of the layer of sheet material product 10 can be bent and deformed away from the bottom surface to be attached to the bottom surface of the mold; and then, other layers of plate products 10 are also stacked and arranged on the first layer of plate product 10 in the direction that the splices 100 face the bottom surface of the mold, so that the stacked and arranged layers of plate products 10 are arranged on the bottom surface of the mold.

When the gap range of two adjacent pultrusion plates 110 is (0mm,5 mm), the pultrusion plates 110 can be bent and deformed toward one side of the flow guide cloth 200 and can also be bent and deformed away from one side of the flow guide cloth 200, when the plate product 10 is laid toward the bottom surface of the mold, the flow guide cloth 200 or the splice body 100 of the first layer of plate product 10 can be selected according to the radian of the bottom surface of the mold and the like to be laid toward the bottom surface of the mold, and the stacking orientation of the subsequent multilayer plate product 10 is consistent with that of the first layer of plate product 10.
