摘要： PURPOSE:To inhibit cutting of tape material and to enhance productive efficiency of a rubber material preparatory device by pinching the tape material with a screw and a reverse rotated feed roller and controlling the rotation rate of the feed roller and the screw in accordance with thickness, width and hardness of the tape material. CONSTITUTION:In the case of supplying tape material T to the screw 4 of a rubber material preparatory device from an introduction port 3, tape material T is always pinched with this screw 4 and a feed roller 21 reversely rotated and driven therefor and drawn into a cylinder 2 and smoothly and forcibly supplied into the cylinder 2. Therefore at a time for supplying tape material T, levitation of tape material T resulting from back pressure of rubber material at a time for kneading and carrying is prevented. Furthermore the feed roller 21 is rotated at the circumferential velocity of arbitrary constant rate for the screw 4 by an encoders 27, 36, a controlling device 33 consisting of a rate setter 34 and a controller 35 and a driving motor 25 in accordance with thickness, width and hardness of tape material T. This tape material T is supplied into the cylinder 2 at proper feed rate.

摘要： PURPOSE:To improve durability of a tackiness preventing effect by performing knurling work of a metal column member in its peripheral surface and cutting a formed protruding part then performing a plating process in the periphery of the column member, in the case of manufacture for a roller or the like feeding a thin thickness rubber sheet to a punching machine. CONSTITUTION:Knurling work is performed of a column member 6 except its shaft part. Here a formed recessed part 2 is set in its depth H to about 0.4 to 1.55mm. Next the formed recessed part 2 cuts its protrusion part in the peripheral edge to be removed by cutting work with one part of the peripheral surface of the column member 6. Thus a sharp angular part 12 is formed in the peripheral edge of the recessed part 2. Here the recessed part 2 is set in its depth D to about 0.3mm. And the column member 6, applying to its peripheral surface electroplating, forms a plating layer 4. Thickness t2 of the plating layer is set to about 0.03 to 0.05mm. By this constitution, durability can be improved of a tackiness preventing effect.

摘要： PURPOSE:To accomplish the efficient removal of the vulcanizing granular solid by blasting the same granular solid on the surface of a rubber product with compressed air in an apparatus for removing the vulcanizing granular solid attached to the extrusion. CONSTITUTION:A vulcanized rubber product 2 is continuously fed into a equipment body 7 and a compressed air is jetted strongly from a blow-off port 10c of a blast nozzle 10 through a connecting pipe 9. At this point, the granular solid in the blasting agent storage section 5 is sucked up to the blast nozzle 10 via a sucking pipe 13 and jetted out of the blow-off port 10c with the compressed air. The granular solid attached to the rubber surface is beaten off by the solid jetted from the blow-off port 10c. The granular solid thus removed can be reused for the heating medium. In this manner, the re-use of the granular solid removed permits direct, continuous reduction eliminating the trouble of drying the granular solid and the like.

摘要： PURPOSE:To make it possible to control the outline dimensions of a product by a method wherein an extrusion molder can be controlled on the basis of the threshold value of extrusion speed exactly corresponding to the actual extrusion speed and, at the same time, the scattering of the characteristics of molding material and of foaming characteristics can be treated. CONSTITUTION:The outline dimensions of an expanded workpiece 30 are detected with a second outline dimension detecting means 18, while the outline dimensions of a workpiece 20 just after the extrusion from the die 6 of an extrusion molder 1 are detected with a first outline dimension detecting means 8. By comparing the detected outline dimensions with the standard outline dimensions, and correcting the dimensional change due to foaming, the extrusion standard corrected dimensions is obtained corresponding to which the corrected speed is determined. The rotational frequency of the screw 3 of the extrusion molder 1 is determined on the basis of the corrected speed corresponding to the extrusion standard corrected dimensions through a screw controlling means 27.

摘要： PURPOSE:To provide the vented extruder capable of discharging surely the gas contained in rubber material or resin material, and being easily produced. CONSTITUTION:While the outer peripheral surface 6a of a dam 6 is formed in almost parallel to extruding direction, the distance-forming member 9 which has the inclined surface 9a formed so that the distance (d) between the inner peripheral surface of a cylinder 2 and the dam 6 is decreased toward the extruding direction, is arranged on the inner peripheral surface of the cylinder 2. Further, the distance-forming member 9 is made movable in the axial direction of a screw 3.

摘要： PURPOSE:To stabilize the weight of a resin molded product by blowing cool air from a cooling means to a powder accommodating box until the time of starting the action of feeding resin powder filled in the powder accommodating box into a mold. CONSTITUTION:Ducts 19 and 20 are disposed around a skin powder accommodating box 18 and a foam powder accommodating box 21, and as cool air is fed from spot coolers 20 and 23 to said ducts, cool air is blown from air outlets 19a and 22a of said both ducts 19 and 22 to powder accommodating boxes 18 and 21. Thus, the temperature of skin powder S and foam powder F can be maintained almost constant. Therefore, in case multicycle powder slush molding is carried out by using a molding device 4, the temperature of both powders S and F is almost constant, and the weight of resin molded product 1 thus manufactured is stabilized.
