    摘要： 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.

    摘要： A pipe-end-connecting joint comprisse a nipple 1 inserted in the pipe end, a holder 2 for tightening the outer circumference of the pipe end, and an elastic packing 3 divided into half parts and attached in the holder 2. The nipple 1 includes a tubular portion 11 provided in one longitudinal end side thereof so as to be inserted in the pipe end, a connection portion 12 provided in the other longitudinal end side thereof so as to be connected to another joint, and a flange portion 13 provided in a longitudinal intermediate portion thereof so as to protrude outward. The holder 2 is divided longitudinally into two split parts 2A and 2B so that each of the two split parts 2A and 2B has an semicircularly formed inner circumferential surface 21, and each of the two split parts 2A and 2B has one longitudinal end side in which one of the half parts of the elastic packing is mounted, and has the other longitudinal end side in which a ring-like groove 23 is formed so as to be fitted to the flange portion 13, and further has a longitudinally intermediate portion between the one and the other longitudinal end sides in which a spiral corrugated portion 22 is formed along the outer circumferential surface of the pipe P, the spiral corrugated portion 22 having a spiral protruding portion 24 an inner diameter of which is smaller than an outer diameter of a trough portion r of the pipe P, the two split parts 2A and 2B having holes for insertion of connection bolts.
