Abstract

The calendered thermoplastic sheet is produced when one or both of the calender rolls used have surface grooves or pockets to produce a complementary pattern of ribs or spots of increased thickness. The pattern is pref. superimposed onto a freshly extruded feedstock sheet as an intersecting network of ribs with an annular rib at certain intersections to provide a tear resistant collar for support pins etc.
