Abstract

1,125,133. Sheet forming. CALMEC EXTRUFORM Ltd. 26 Oct., 1965 [17 June, 1965], No. 45294/65. Divided out of 1,125,132. Heading B5A. The subject matter of this Specification is identical with that of Specification 1,125,132, but the claims relate to a deep drawing process in which the sheet is pre-cooled in certain regions to prevent wrinkling during the subsequent drawing operation.
