Abstract
An internal mixer for kneading and rolling includes a mixing chamber containing two parallel spaced shafts. Kneading blades and arcuate roller surfaces are provided on the outer peripheries of the shafts. The arcuate surfaces are so disposed on the shafts such that a gap is formed therebetween when in their innermost positions. The arcuate surfaces and kneading blades are disposed serially in the peripheral direction on the shafts. The shafts rotate in opposite directions and so as to provide the same peripheral speed for the arcuate surfaces.
