摘要： PURPOSE:To measure abrasion resistance in an actual use state by rotating a test piece on its own axis and revolving other test piece in contact with said test piece in an eccentric state. CONSTITUTION:The end piece 30 on the side of revolution and that of a test piece 84 on the side of rotation are brought to a contact state and the pressure between both pieces due to the operation of a screw shaft 94 is detected by a pressure sensor 32. The piece 84 rotates on its own axis by the rotation of a motor 60 and this rotation is transmitted to a rotary shaft 40 to be further transmitted to a revolving stand 12, and a mount stand 20 and a test piece mount member 26 on the side of rotation revolve around the axis of the stand 12. Therefore, the test piece 30 also revolves around the axis of the stand 12 (the axis of a test piece mount member 82 on the side of rotation). The test piece 84 rotates on its own axis around the axis of the member 82 and the test piece 30 revolves around the axis of said member 82 and an abrasion test can be performed in a contact state wherein both pieces 30, 84 are always changed and, therefore, an abrasion resistance test can be performed in an actual use state.

摘要： PROBLEM TO BE SOLVED: To simply and safely regulate a gap between the edge of a fixed blade body and the edge of each blade plate in a rotary blade body. SOLUTION: This apparatus is equipped with a fixed blade body 2 having an edge intersecting the direction of advance of a strand perpendicularly and with a rotary blade body 3 which is fixed to the fore end of a rotary shaft 13 intersecting the edge of the fixed blade body 2 perpendicularly and also has a plurality of blade plates 15 disposed radially on the front face 3a, and the rotary shaft 13 is supported rotatably by a support member 14 opposed at a space to one side of the fixed blade body 2, through the intermediary of a bearing mechanism 30. The support member 14 is guided by a pair of guide plates 39 so that it can move straight in the same direction as the axis of the rotary shaft 13, and it can be fixed by a set bolt after a gap between the edge 2a of the fixed blade body 2 and the edge 15a of the blade plate 15 is regulated by moving the rotary blade body 3 straight in that direction together with the support member 14.

摘要： PROBLEM TO BE SOLVED: To obtain a uniform flowing velocity in all width direction area of a die head, followed by a wide melt viscosity by providing a pair of flow rate regulating bars rotatable across a resin channel, and changing the flow rate in an axial direction. SOLUTION: Resin material of melted state supplied from an extruder is heated by a heater 9, fluidized in a resin channel 2c while holding its fluidity, and extruded as strands from many nozzles of a die 3. The channel 2c is formed in a low channel section (narrow width) at a center with satisfactory fluidity and in a high channel section (wide width) near both ends with wrong fluidity and regulated in a desired height so that resin material becomes uniform velocity in all width direction area of the channel 2c. The material can be dealt with wide melt viscosity of the material. And, the material can be extruded as the strands at the same velocity from all the nozzles of the die 3 b rotating flow rate regulating bars 11, 12. Accordingly, disassembling and assembling operations of the flow rate regulator for regulation can be eliminated.

摘要： PROBLEM TO BE SOLVED: To make it possible to always maintain the excellent sharpness by cutting a purge resin material to small pieces without using a large driving force by repeatedly crossing the material to be externally discharged of a screw type kneader by a fine-wire. SOLUTION: A resin material of a molten state to be discharged from the end of the inner hole 2a of a cylinder 2 is fed from a lower end surface 6c into the inner hole 5 of a valve case 5 via the lower channel 6b of a piston 6, and discharged from the discharge surface 7b to the outer lower part via the exhaust port 7a of a cover 7. On the other hand, the extruded piston of one hydraulic cylinder 15b is returned, simultaneously the extruding operation of the piston to be returned of the other hydraulic cylinder 15b is repeated, and hence a fine-wire extended in a tensioned state is repeatedly reciprocated and crossed at the port 7a along the surface 7b. The resin material discharged via the port 7a is cut by the fine-wire repeatedly crossed, and dropped down as small pieces.

SOLUTION: A motor shaft 10 for supporting a rotor of a built-in motor 5 is formed in a hollow state, and a cutter shaft 12 is axially movably inserted into the hollow part. A cutter bearing 16 for rotatably and axially immovably supporting the shaft 12 is axially movably inserted into a casing 15 fixed to the side plate 7 of the motor 5. A finely regulating threaded ring 19 is provided by engaging with the casing 15 between the casing 15 and the bearing 16. Thus, the bearing 16 is pressed by a compression spring 25, and the play of the threaded part of the ring 19 is always stained in one direction. A cutter driver having a function of finely regulating the axial movement of the shaft 12 by rotating the ring 19 is provided.
