ールワイヤ[Industrial Field of Application] The present invention relates to a method for manufacturing molded sheets such as Dalashi boards and heel maps for automobiles. [Prior Art] Conventionally, in order to manufacture such a molded sheet, a method has been used in which the original sheet is cut, molded, and then trimmed. [Problems to be Solved by the Invention] However, the conventional method described above involves three steps, and productivity is extremely poor due to the difficulty of continuous processing.In addition, material is broken due to trimming, resulting in material loss. I was sick of wasting money. [Means for Solving the Problems] As a means for solving the above-mentioned conventional problems, the present invention provides the following:
A plurality of curved parts of a predetermined shape are provided in the longitudinal direction on a strip-shaped releasable base material, and while the base material is being conveyed, the molding material is coated and filled into the recessed part by a coating machine, and then the recessed part is filled with the molding material. The molding material is solidified to form a molded sheet, and the resulting molded sheet tf
The present invention provides a method for manufacturing a molded sheet that is removed from the recess. [Releasable base material] Silicone rubber is used as the releasable base material used in the present invention. Teflon rubber, Teflon coated steel belt,
The band V is made of a releasable and flexible material such as a silicone coated steel belt. Stretchable materials such as silicone rubber and Teflon rubber stretch due to tensile stress during transportation, so it is desirable to line or embed steel net, steel wire, steel belt, etc. to prevent such stretching. On such a releasable base material, a plurality of recesses in a predetermined shape, for example, in the shape of a car pad or a heel mat, are provided in the longitudinal direction. The base material is conveyed in the same manner as a belt conveyor, and for such conveyance, the releasable base material is preferably wound into a roll or rolled into an endless shape. [Molding material] As the molding material used in the present invention, plastisol or organosol such as kerosene IJ m-vinyl paste,
Thermoplastic melts such as polyethylene melts and polypropylene melts, urethane prepolymers,
Epoxy resin prepolymers, prepolymers such as unsaturated polyesters, methyl methacrylate, monomers such as styrene, etc. are liquid materials that can be applied, heated and cooled. It is solidified by adding a catalyst or the like. For example, plastisol is solidified by heating and gelling.
If it is a thermoplastic melt, it will solidify as it cools, and if it is a prepolymer, it will react with steam, amine catalyst,
Contact with an acid catalyst, etc. by spraying or coating, preferably by heating, to make it polymeric and /''! or three-dimensional and solidify it, and if it is a monomer, add a polymerization initiator before coating and /''! It is added after being applied and is preferably heated to polymerize and solidify. A commonly used coating machine such as a knife coater, roll coater, curtain flow coater, or spray gun is used to apply and fill the molding material into the recesses of the releasable base material. Two types of coating machines may be used in combination, such as spray filling the molding material with a knife coater and squeezing it with a knife coater. After the molding material is applied and filled into the recesses of the releasable base material, it is solidified into a burst molded sheet by the above-described solidification means, and the obtained molded sheet is taken out from the recesses. [Operation] When a molding material is applied and filled into a plurality of recesses of a predetermined shape provided in the longitudinal direction on the releasable base material and the molding material is solidified and mixed, a shape corresponding to the shape of the recesses is formed. A sheet is obtained. Since the base material has releasable properties, the molded sheet can be easily peeled off from the recess and taken out. Further, since the molding material is applied and filled into the recesses and solidified while the base material is being conveyed, molded sheets can be continuously manufactured. [Effects of the Invention] Therefore, according to the present invention, a molded sheet can be manufactured continuously through only two steps: coating and filling, and solidification, and the trimming step can be omitted, so no broken material is generated.
It also prevents wastage of materials. [Example] The present invention will be explained using a one-shot example shown in Figs. 1 and 2. rxl is a band-shaped body (]) made of Teflon rubber.

される。[1] An m-type base material consisting of B, on which a plurality of recesses fllc in the shape of an automobile Dallathy board are provided at regular intervals in the longitudinal direction. , the releasable base material ( ) is in the shape of an endless belt and is suspended between three transport rolls (21, FIML, +41).
A guide roll (5) for recessing the base material (1) is interposed between the transport roll (4) and the transport roll (2), and a guide roll (6) is also interposed between the transport roll (4) and the transport roll (2). Then, the knife caulk (7) was set on the base material (II) at the position of the conveyance roll (81), and the base material (1) was set between the conveyance roll (3) and the conveyance roll (4). It is guided to a heating furnace (8), and a cold air device (9) is arranged immediately after the heating furnace (8),
In addition, the guide roll (51 direct, below which is the collection tank QQ), and the drive source is connected to the transport roll (21).The thickness of the base material is 4srm, and the depth of the recess is Bnx. In the above configuration, the substrate (1) is conveyed in the direction of the arrow in FIG. 1 by driving the conveying roll [2], and the knife coater (7
], the polyvinyl chloride paste αB is applied and filled into the recesses [1)C of the base material (1), but the polyvinyl chloride paste αυ overflowing from the recesses [])C flows down the base material (1) and is deposited on the guide roll. At the position (5), it is dripped and collected from both sides into the collection tank a1. The polyvinyl chloride paste α'1lfl applied to and filled in the recessed part []) C of the base material (]) is heated at approximately 180° C. for 8 minutes in a heating furnace (8), thereby gelling and forming a dash board mackerel. The Darashi board a2 thus obtained is cooled in a cold air device (9) and then taken out.
