METHOD AND APPARATUS FOR LAMINATING THERMOPLASTIC SHEETS

摘要

Thermoplastic sheets (X) to be laminated into a laminated assembly (Y) in one cycle are heated while the sheets are arranged in a juxtaposed relationship in the order in which they are to be laminated. The heated sheets (X) are penetrated with needles (31) to detachably hold the sheets while keeping the sheets in the juxtaposed relationship. A support member (17) which supports the laminated assembly (Y) is moved below the sheets (X) held and relative to the sheets in a direction in which the sheets (X) are released from the needles (31) onto the support member (17) to stack the sheets thereon into the laminated assembly (Y) while the support member (17) is being moved relatively to the sheets (X). The support is then delivered into a shaping die assembly. The laminated assembly (Y) on the support member (17) which has been delivered into the shaping die assembly (2) is charged into a charging position in the shaping die assembly (2), and the support member (17) is then pressed into a shaped product with the shaping die assembly (2) after the laminated assembly (Y) has been charged into the charging position.
