Claims
6. A process for producing a multilayer molded article
comprising a core layer and a skin material laminated thereon,
which process comprises the steps of:
mounting a skin material between a pair of upper and
lower molds by fixing an edge portion of said skin material to
a plurality of pre-positioned pins provided on a skin material
fixing frame;
supplying a thermoplastic resin melt between said skin
material and one of said molds;
closing the molds to press and form said resin melt while
simultaneously moving said skin material fixing frame along an
outer peripheral wall of one of said upper and lower molds, to
thereby hold the edge portion of said skin material such that
said edge portion of said skin material is locally cut at one
or more of said pins according to a shape of the molded
article and a tension at any one of said pins during said step
of closing; and
cooling said molds and removing said multilayer molded
article from the molds.
10. In a process for producing a multilayered molded
article which includes the steps of mounting a skin material
between upper and lower molds by fixing an edge portion
thereof to holding pins, supplying thermoplastic resin melt
between said skin material and one of said molds, and closing
the molds so as to form a laminated molded article, the
improvement which comprises:
controlling the tension of said skin material during said
mold closing step by preselecting the location and diameter of
the holding pins such that said edge portion is controllably,
locally cut by at least one of said pins, thereby
appropriately controlling the tension of the skin material and
reducing the occurrence of skin wrinkling and breakage in the
molded article;
wherein said molded article does not contain the edge
portion of the skin material.
