- An endless belt 84 is wound around pulleys 85a and 85b-85c-85d from the lower part to the upper part of the kneading roll 11, and an endless belt 86 is surrounded by a pulley 87a around the outside thereof. It is wound around 87b * 87c'87d and rotates in the direction of the arrow.
- the lower surface of the upper end of the endless belt 84 is in contact with the lower surface of the endless belt 86, and the scrubber 89 is in contact with the lower surface of the upper end of the endless belt 86.
- the resin compound 36 introduced into the valley between the kneading rolls 11 and 12 adheres to the kneading rolls 11, but a part of the resin compound falls from the minute gap and falls on the endless belt 86.
- the resin compound 36 is conveyed to the upper part by being sandwiched between the endless belt 84 and the endless belt 86, dropped off by the scrubbers 89 and 88, and again has a valley between the kneading rolls 11 and 12. Fall to
- FIG. 13 shows a modified example of the cleaning roll 22 (see FIG. 1) for cleaning the kneading rolls 1 1 and 1 2.
- the sliding contact surface of the cleaning roll 22 connected to the air cylinder 21 is shown in FIG.
- Cleaning cloth 90 is covered.
- the cleaning cloth 90 is in the form of a long strip, is unwound from a rolled supply source, is wound around the cleaning roll 22 and wound up in a roll, and is always new to the kneading rolls 1 1 and 1 2. A clean cloth surface comes into sliding contact.
- the cleaning cloth 90 may be folded on the folding screen on the supply source side.
