  • Patent number: 5589202
    Abstract: A method and apparatus for producing a molded polyurethane foam without using low-boiling solvents such as Freon and methylene chloride which present problems when used as a blowing agent. The polyurethane foam has the same good appearance and soft feeling as that produced with low-boiling solvents. A polyurethane foam is produced by injecting a polyurethane material into an evacuated cavity and permitting it to expand so that it flows and fills the cavity, said polyurethane material being composed of 100 parts by weight of polyol component and 0.1-0.6 part by weight of water as a blowing agent. The cavity pressure may be maintained high spontaneously or low while the polyurethane material is flowing in the cavity. When the polyurethane material has reached the final fill position in the cavity, the fore-end of the polyurethane material is discharged from the cavity.

  • Patent number: 4555069
    Abstract: An improved method and apparatus for winding a yarn on a package are disclosed. The apparatus comprises the package supported on a pair of cradle arms and driven by a friction roller, with a traverse guide disposed between a traverse drum and a cam plate so as to reciprocatingly traverse the yarn from one end of the package to the other. The traverse cam plate is positionally controlled to vary the width of the traverse by an arcuate cam, affixed to the cradle arm, acting on a first pivoting lever connected by a rod to the cam plate such that the width of the traverse is decreased as the package size grows. A second cam, affixed to the cradle arm acts on a second lever during an initial winding period to maintain a pivot axis of the first lever in a fixed position.
