Abstract

Задачей настоящего изобретения является создание способа оснащения листа на основе термопластического полимера эластизированной областью, выполненной с возможностью растягивания и стягивания в ее направлении толщины, без опасности разрыва листа на основе термопластического полимера и к листам, полученным по этому способу. Настоящим изобретением предложен способ оснащения листа 10 на основе термопластического полимера на расстоянии от его внешней наружной кромки 12 эластизированной областью 11, выполненной с возможностью растягивания и стягивания в направлении толщины листа, путем использования неподвижного формующего блока 5 и подвижного формующего блока 6, каждый из которых имеет формующие лопасти 2, при этом указанный способ отличается тем, что формующие лопасти размещены таким образом, что проекции их поперечных сечений на лист образованы подобными кривыми линиями и/или изогнутыми линиями, расположенными вокруг центра подобия, причем указанные формующие лопасти проходят в направлении толщины листа от неподвижного и подвижного формующих блоков с возможностью быть вставленными друг в друга, но не приходить в контакт друг с другом, а способ включает этап размещения листа между неподвижным и подвижным формующими блоками и этап вставления формующих лопастей неподвижного и подвижного формующих блоков друг в друга для растягивания листа между удаленными концами каждой пары смежных формующих лопастей. Также предложен лист, полученный этим способом.
