摘要:
A process for producing a tire according to a strip build technique by the use of an injection molding machine, in which strip rubber injection can be performed in the state of being uniform in the blending degree and plasticity level of rubber material. There is provided a process for producing a tire by the use of injection molding machine (A) equipped with material feeding aperture (8) for charging of rubber material, screw (1) for driving forward in the axial direction of the charged rubber material while blending the same, material charging compartment (4) disposed on the distal end side of the screw (1) and material passage (C) for feeding of the rubber material from the distal end side of the screw (1) to the material charging compartment (4). The process comprises the steps of feeding the rubber material from the material feeding aperture (8), driving the rubber material forward while blending the same by means of the screw (1) and through the material passage (C), charging the material charging compartment (4) with the rubber material; causing the screw (1) and material feeding aperture (8) to retreat; advancing the screw (1) and carrying out injection of strip rubber from the material charging compartment (4); and winding the strip rubber (S) while rotating forming drum (B) to thereby make tire configuration.

摘要:
An object of the invention is to provide a brake apparatus which can facilitate slope starting and slope climbing and which can be produced small in size and light in weight. In addition, another object of the invention is to provide a brake apparatus which can obtain a stable brake force under any conditions including running in the rain.The invention provides a brake apparatus in which a restriction is imposed on the rotation of a wheel (101) via a brake drum (3) provided on a rotational shaft of the wheel (101) so as to rotate together with the rotational shaft, the brake apparatus being characterized by comprising a brake shoe (30) for imposing a restriction on the rotation of the brake drum (3) in a forward or backward direction through wedge engagement with an inner circumferential surface of the brake drum (3) when the brake drum (3) rotates either in the forward direction or in the backward.

There is provided a sound-absorbing and a heat-insulating duct comprising a nonwoven cloth layer 1, a reinforcing core 2, a foam strip layer 3, a bonding resin 4 and resin-coating layer 5. The nonwoven cloth layer 1 is formed by wound spirally a nonwoven cloth 10 into a tube-like shape in which adjacent side edges of the adjacent nonwoven cloths 10 are brought in abutment against or lapped with each other so as to form a bonding portion 1a. The reinforcing core 2 made of hard synthetic resin material is wound spirally on the bonding portion 1a while a surface of the reinforcing core 2 being brought into contact with the nonwoven cloth 10 is welded or bonded to the nonwoven cloth 10. The foam strip layer 3 is formed by wound spirally a foam resin strip 30 having a width approximately equal to a width of the nonwoven cloth 10. Both adjacent edges 3a, 3b of the foam resin strip are disposed on adjacent reinforcing cores 2, 2 respectively. The bonding resin 4 is applied to a side surface 30B of the foam strip 30 and a part 2A of the reinforcing core 2. The resin-coating layer 5 is provided to cover an outer circumferential surface of the foam strip layer 3. Accordingly, it is possible to provide a sound-absorbing and heat-insulating functions, which is suitable for use as an air-blow duct, and which is suitable for continuous production so that the duct can be mass-produced inexpensively.
