ABSTRACT:
A method and apparatus are employed to convert a conventional slitter into a four high cold reduction mill. According to the preferred embodiment the blades of the slitter are removed and the upper and lower arbors are separated to place a pair of work rolls in between. A left and right side support unit is mounted on the upper and lower arbors. The left and right support units each carry a pair of upper and lower arbor housings for attachment to the upper and lower arbor shafts and a second pair of housings for mounting the upper and lower work rolls between the upper and lower arbors. Packing sleeves are fitted on the upper and lower arbor shafts so that the converted upper and lower arbors act as back-up rolls for the upper and lower work rolls. According to an alternative embodiment of the invention, the entire slitter head including its inboard and outboard housing is replaced by an entirely new four high head including its own inboard and outboard housing. The advantage of the present invention is that it is possible to perform slitting and cold rolling on essentially the same machine. The device is especially useful where large forces and large reductions in size are not necessary.
