  • Patent number: 4466473
    Abstract: A method of making radial pneumatic tires substantially reduces or eliminates sidewall indentations in the inflated tire. A plurality of cuts is made in one end of each layer of ply fabric where the end of the ply fabric overlaps the other end to form a splice which results in the generally annular shape of the ply layer. The cuts extend in a direction generally transverse to the end edge and preferably have a length which is approximately the same as the width of the overlap of the cut edge with the other edge. The cuts prevent overtensioning of the ply cords, which otherwise result in sidewall indentations.

  • Patent number: 4460366
    Abstract: Medical bags composed of plastic sheets jointed at their edges and a fluid charging/discharging tube sealed between the edges of the sheets have suffered, due to the use of a mold having smooth and straight land conforming with the surface of the tube, various problems such as formation of burrs by the displaced molten plastic material on the inner side of the product bag, weakening or generation of pinholes around the free end of the tube attributable to excessive thinning of the sheets and so forth. According to the invention, these problems are overcome thanks to the use of a mold which has a central first land of an inside diameter slightly smaller than the sum of the tube diameter and thicknesses of sheets and at least one additional land provided at each side of the first land, the additional lands having inside diameters increasing successively and slightly greater than that of the first land.
