Abstract
In a hot pressing apparatus, a hot-plate pressing cylinder is provided at the center of a moving plate, and a substantially central part of each of the materials to be laminated between hot plates, which are pressed by a fixed plate and a moving plate, is pressed by a hot-plate pressing cylinder of the moving plate. Thus, a uniform pressure can be applied to the materials to be laminated, thereby preventing the occurrence of defects such as wrinkles and bubbles in the products.
Claims4
A hot pressing apparatus comprising:
- a plurality of hot plates in a chamber;
- a moving plate disposed below the hot plates;
- a fixed plate disposed above the hot plates;
- a moving-plate operating means disposed on the fixed plate, for moving the moving plate toward the fixed plate;
- a moving plate-retaining means provided on the fixed plate, for retaining the moving plate;
- and
- a hot-plate pressing means comprising a ram and a ram cylinder, and provided at the center of the moving plate for pressing a substantially central part of each hot plate;
- wherein the moving plate-operating means is provided with a plurality of shaft members for supporting a periphery of the moving plate, and
- materials to be laminated are disposed between the plurality of hot plates, and the moving plate is moved toward the fixed plate along the shaft members by the moving Plate-operating means, so that the materials to be laminated between the hot plates are hot pressed and integrally laminated.
