The CJJF is a fully automatic coreless slitter rewinder developed by Jennerjahn Machine. Modeled after the successful JJS and JJF slitter rewinders, the new machine addresses the need for small roll production without using a core. A special rewind shaft designed by Jennerjahn Machine is utilized. The shaft works in conjunction with specially engineered mechanical chucks that automatically expand and contract the shafts. Typical applications include box tape, photo paper, red rosin and counter rolls up to 54 inches wide.
