A strand cutting apparatus includes a fixed blade,having a blade edge extending perpendicularly with respect to the traveling direction of a strand, and a rotation blade,which is fixed to the tip portion of a rotation shaft,extending perpendicularly to the blade edge of the fixed blade,and has a plurality of plate-shaped blades,disposed radially at a front surface,The rotation shaft,is supported by a supporting member,through a bearing mechanism,so as to be freely rotatable. The supporting member,is opposed to the one side of the fixed blade,with a clearance therebetween. The supporting member,is guided by a pair of guide plates,so as to be movable freely and linearly along the same direction as the axial direction of the rotation shaft,The rotation blade,is moved linearly to this same direction together with the supporting member,to adjust a clearance between the blade edge,of the fixed blade,and the blade edges,of the plate-shaped blades,and then the supporting member can be fixed by using stop bolts

Method and apparatus for cutting strand

The invention is for mixing at least one kind of an additive with a powdery or granular main material homogeneously so as to continuously supply the same quantitatively. A barrel comprises a front side cylindrical part, a trough part, and a rear side cylindrical part from the upstream side. A quantitative extruding zone comprises the front side cylindrical part and a quantitative extruding part having a full flight provided on the peripheral surface of the axis part of a screw, for quantitatively transporting a main material to the downstream side. A mixing zone comprises the trough part and a mixing part having an agitating blade formed zigzag on the axis part of the screw and a ribbon screw having a distance with respect to the peripheral surface of the axis part, for homogeneously dispersing additives added from additive supply openings in the main material. The scraping out zone comprises the rear side cylindrical part and a scraping out part having forward paddles and backward paddles formed alternately on the peripheral surface of the axis part of the screw, for discharging the mixture from a discharge opening.

Continuous mixing feeder

A die formed of a series of concentric rings is disclosed. An outer body has a series of communication ports for the introduction of a heating medium. An inner body having the same axial thickness as the outer body is placed inside the outer and in the annular space defined between the inner and outer bodies a series of annular rings are placed. The annular rings each have a series of nozzles disposed in a circumferential ring and are formed with grooves on their outer walls to define jackets between the rings. The jackets are in communication with the communication ports to supply a heating medium to the jacket.
