の欠陥があつた。 Conventionally, in the manufacturing method of this type of surface plate, a heat-shrinkable synthetic resin sheet and a heat-nonshrinkable synthetic resin sheet are polymerized, and a plurality of hard core plates are arranged slightly horizontally between these two sheets. At the same time, the two sheets are welded to each other except for the entire periphery and the ends between the hard core plates, and then heated to shrink the heat-shrinkable synthetic resin sheet. There has been a known method in which the entire periphery of a heat-shrinkable synthetic resin sheet is turned over to the contact surface of the heat-shrinkable synthetic resin sheet on a hard core plate by the shrinkage force of the rectifier. In some cases, there are undesired wrinkles that impair the appearance and post-processing between the entire periphery welded part and both ends of the welded part between the hard core plates in the turned part, and the product is not necessarily satisfactory. In some cases, there were defects such as the need to perform a wrinkle smoothing process for the purpose of reducing the wrinkles.

要旨とするものである。 The present invention aims to eliminate the above-mentioned defects by performing partial heating in a two-stage system, and involves polymerizing a heat-shrinkable synthetic resin sheet with a non-heat-shrinkable synthetic resin sheet, A plurality of hard core plates are inserted between these two sheets in a state where they are lined up horizontally with a slight distance between them, and both sheets are placed at the entire periphery of the sheets and at the areas excluding the end portions between the hard core plates. Then, in the heat-shrinkable synthetic resin sheet of this semi-finished product, a narrow portion including the intersection between the entire periphery and the area between the hard core plates is used as a heat-insulating member. The heat-shrinkable synthetic resin sheet was coated with a heat-shrinkable resin sheet to create a heat-blocking state in which it was not subjected to the first heating described later, and the first heating was performed in this heat-blocking state to remove the above-mentioned narrow portion of the heat-shrinkable synthetic resin sheet. By shrinking the entire surface, the entire periphery of the heat-shrinkable synthetic resin sheet, excluding the heat-blocking areas and the corresponding areas, is rolled over to the contact surface of the heat-shrinkable synthetic resin sheet on the hard core plate. Then, after removing the heat shielding member, the above semi-finished product is heated a second time to shrink the parts of the heat-shrinkable synthetic resin sheet from which the heat shielding member has been removed. The gist is to turn over the edges of the heat-shrinkable synthetic resin sheet that correspond to the above-mentioned heat-blocking parts on the entire periphery to the contact surface of the heat-shrinkable synthetic resin sheet on the hard core plate. It is.
以下、本発明の実施例を図面に依拠して説明す

スポンジ１３を重合させた三枚の厚紙製硬質芯版
３，３′，３″を僅かに離して横に並べた状態で挾
入する。 Hereinafter, embodiments of the present invention will be described with reference to the drawings. First, a colorless transparent heat-shrinkable synthetic resin inner sheet 2 of a colored opaque heat-shrinkable synthetic resin outer sheet 1 is polymerized, and both of these are polymerized. Three cardboard hard core plates 3, 3', 3'' on which a sheet-like sponge 13 is polymerized are inserted between the sheets 1 and 2 while being arranged horizontally with a slight distance between them.
然るのち、両シート１，２を其の全周縁個所４
および硬質芯版間の両端部分を除いた個所５，
５′に於て相互に熔着して半製品６を得る。 After that, both sheets 1 and 2 are attached to their entire periphery 4.
and the part 5 excluding the both end parts between the hard core plates,
At step 5', they are welded together to obtain a semi-finished product 6.
次いで、この半製品６の内面シート２に於て上

り返す。 Next, in the inner sheet 2 of this semi-finished product 6, the narrow portions 7, 7' including the intersections between the entire periphery 4 and the areas 5, 5' between the hard core plates are covered with a heat shielding member 8. The entire surface 9 of the inner sheet 2 excluding the narrow portions 7 and 7' is heated for the first time in this heat cut-off state, and the entire surface 9 of the inner sheet 2 excluding the narrow portions 7 and 7' is heated for the first time in this heat cut-off state. By shrinking, the entire periphery 10 of the outer sheet 1 except for the areas corresponding to the heat shielding areas is formed into hard core plates 3, 3',
Turn it over to the contact surface side of the inner sheet 2 at 3''.
然るのち、熱遮断用部材８を取去したのちに上

捲り返す。 After that, after removing the heat shielding member 8, the semi-finished product 6 is heated a second time to shrink the portion of the inner sheet 2 from which the heat shielding member 8 has been removed. Therefore, the edge portion 11 corresponding to the heat-blocking portion on the entire periphery of the outer sheet 2 is turned over to the contact surface side of the inner sheet 2 on the hard core plates 3, 3', 3''.
次いで、内外両面シート２，１の熔着縁１２を

皺伸し工程を施す必要がない等の好ましい利点も
ある。 As described above, the present invention has the remarkable effect of being able to complete a table plate in which the welded edge does not protrude beyond the outer periphery through an extremely simple process. By doing this, there is no need to worry about the formation of unwanted wrinkles that impair the appearance or post-processing between the entire circumference welded part and both ends of the welded part between the hard core plates in the turned part. (In some cases, small wrinkles may remain.) This method has the effect of being able to provide products with high commercial value, and also has favorable advantages such as not requiring a wrinkle smoothing process.
