Apparatus for bending channel section members

摘要: An apparatus for bending an elongate member with a pair of spaced parallel planar flanges which normally extend from the web to form channel section. The includes platen shaped close fitting engagement exterior and flange faces in region where is bent. also counter-pressure member, one surface engages face region. capable being selectively advanced or retracted within platen. A movable head interior has projections apply force acting planes on longitudinally portions relative displacement portions. During this displacement, projection maintained while are closely so that position.
