Abstract

PURPOSE:To continuously and efficiently manufacture panel by a method wherein the cutter of rear material is provided at an arbitrary position between an uncoiler and a core material delivery part and preferably at least one position between a preheater and the delivery part. CONSTITUTION:In order to realize a compact production equipment, a second and a first trestles 2 and 15 are installed on the third floor and on the second floor of a three-storeyed house. The decorative surface of surface material A after passing through an embossing part 9 is faced upward so as to easily discover the generation of cracks and the like at embossing. The surface material A and a back material B, which are respectively coiled on uncoilers 4 and 17, are installed at the feed parts 3 and 16 of the surface material and of the rear material so as to feed without strain the decorative surfaces of the surface material A and of the rear material B under the state being faced upward to turning-over parts 11 and 24. Forming parts 12 and 25 consist of groups of pinch rollers, levers and forming rolls so as to form the surface material A and the rear material B. At a delivery part 28, solid reaction mixture P is delivered and filled to the inside of at least either one of the surface material A and the back material B, both of which have been heated at preheater parts 13 and 26 respectively. The cutter 27 of the rear material cuts the rear material B preferably at a position between the delivery part 28 and the preheater part 13 by a command issued from a control panel when the surface material A is used up during operation in order to make the waste of the rear material B as small as possible.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention interposes a self-adhesive core material material between two base materials of a composite plate, and enables continuous and efficient mass production of the composite plate. The present invention relates to a panel manufacturing device.

[Prior Art] Generally, a metal hoop material is used as a surface material, which is formed into a gutter-like body with an arbitrary cross section, passed through a preheating device, a backing material is laminated thereon, and heated to 30 to 150''C. After being fed to a double conveyor equipped with a heating duct, the above raw materials are reacted and foamed to produce a composite plate strip with a synthetic resin foam interposed between the front and back materials, and then cut into regular lengths. An example of a device for this purpose is disclosed in Japanese Patent Application Laid-open No. 1973-123076.

[Problem to be solved by the invention]

However, in this type of equipment, when the front and back materials are made of metal hoop materials with different thicknesses, or when the back materials are connected and used, the end of the front material and the end of the back material are not necessarily the same. In other words, there was an inconvenience that the backing material remained even after the fronting material was finished, and cutting the backing material at a portion of the uncoiler did not eliminate waste.

[Means to solve the problem]

In order to eliminate such drawbacks, the present invention provides a back material cutting machine at any position between the uncoiler and the core material discharge section, preferably at least one location between the preheater and the discharge section, so that the panels can be cut continuously. Moreover, the present invention proposes a panel manufacturing apparatus that can be manufactured efficiently.
