Abstract:
1. An apparatus for forming a panel having a lower mold which is fixed and an upper mold which is provided above the lower mold and reciprocates up and down in a vertical direction, and compressing a plurality of base materials fed to front ends of the lower and upper molds to form the panel, the apparatus comprising: a first mold unit including a right-angled upper mold which is provided on a front portion of the upper mold and reciprocates up and down in the vertical direction, and a right-angled lower mold which is provided on a front portion of the lower mold to correspond to the right-angled upper mold and is fixed, thus compressing the base materials against each other to impart a pattern of a right triangular waveform; a second mold unit including an obtuse upper mold which is provided on a central portion of the upper mold and reciprocates in a direction inclined relative to a direction of progression of the base materials, and an obtuse lower mold which is provided on a central portion of the lower mold to correspond to the obtuse upper mold and is fixed, thus compressing the base materials against each other to impart a pattern of an obtuse triangular waveform; and a third mold unit provided behind the second mold unit, and linearly pressing the base materials compressed by the second mold unit in a direction from front to rear.
