Kneading device and ropesizer
First Claim
Patent Images
1. A kneading device which kneads a raw material of high viscosity and a raw material of low viscosity and continuously delivers a raw material mixture obtained, comprising:
- a casing;
a pair of screw shafts disposed parallel to each other in said casing; and
, a driving unit for rotating said screw shafts, wherein a helical portion is formed at one end of said pair of screw shafts so that said raw material is conveyed from one end of each of said pair of screw shafts to the other end, and a plurality of mixing pins is provided with the other end side of said screw shaft with regard to said helical portion in the circumferential direction of said screw shaft.

10. A kneading device which kneads a main raw material of high viscosity and a secondary raw material of liquid or powder and continuously delivers a kneaded raw material obtained, comprising:
-
a casing having an opened upper portion;
a pair of mixing blades disposed parallel to each other in said casing; and
,a driving unit for rotating said mixing blades, wherein each of said pair of mixing blades comprises a unit blade of a U-shape continuously attached in a wavy shape, and said pair of the mixing blades rotate with their rotational phases shifted so that they do not interfere with each other. - View Dependent Claims (11, 12, 13)

14. A ropesizer, comprising:
-
a sheet forming unit for elongating a first raw material into a sheet shape;
a delivering unit which applies a second raw material onto the first raw material, which is elongated in sheet shape and conveyed by said sheet forming unit, so as to be in a strand form; and
,a wrapping means for wrapping the sheet shape first raw material, while the sheet shape first raw material is being conveyed, so as to wrap the second raw material, which is applied as a strand form, in the first raw material. - View Dependent Claims (15, 16, 17)
