Abstract

PURPOSE:To make possible the formation of tapers of a good section and improve the yield of rolling by forming the pressing tools for forming tapers into a grooved U-shaped sectional shape and grasping the end part of a plate material with the groove parts. CONSTITUTION:The plate material grasping side in pressing tools 8, 8' are formed to a U-shaped cross section having grooves 15, 15'. The cross sectional shape of the grooves 15, 15' is formed at about l=(0.5-1.5)H in a relation between a depth (l) and a plate material thickness H prior to working and about 5-15 deg. in the degree of opening to the outer side direction of the grooves. Owing to the use of these pressing tools 8, 8', the occurrence of folding phenomena and formation of abnormal shapes such as nodes at the plate material end parts is obviated and the good taper formation is accomplished.
