A roll mill comprising:

• a housing;
• a first pad supported in and movable relative to said housing;
• a second pad supported in and movable relative to said housing;
• a first bearing mounted in said first pad;
• a second bearing mounted in said second pad;
• a main roll rotatably mounted in said first and second bearings;
• an auxiliary roll adjacent to said main roll with strip being passed between said main roll and said auxiliary roll, the axis of said auxiliary roll lying in a first transverse plane and the axis of said main roll lying in a second transverse plane, said first plane being parallel to said second plane;
• a control means to control the profile and shape of the strip as the latter is being passed between said rolls, comprising:
• a crosspiece carried on and movable relative to said housing and having a groove provided in one of its surfaces, and having spaced first and second channels extending transversely of and between said groove and a second surface of said crosspiece;
• a wedge slidably received in said groove of said crosspiece;
• a drive means connected to said wedge for moving said wedge along said groove;
• a collet pivotally attached to said crosspiece and having a first groove and a second groove, said collet supporting said auxiliary roll adjacent said main roll;
• a first insert received in said first groove of said collet;
• a second insert received in said second groove of said collet;
• a first cam movably carried in said first channel and interposed between said wedge and said first insert;
• a second cam movably carried in said second channel and interposed between said wedge and said second insert;
• whereby actuation of said drive means causes said wedge to slide along said groove to simultaneously move each of said cams and pivot said collet and the axis of said auxiliary roll relative to the axis of said main roll.
