    摘要: A pressure vessel includes a vessel body including a cylindrical-shaped straight body portion with a spiral-shaped projection portion formed at an outer peripheral surface of the straight body portion, and a covering portion that comprises a fiber bundle wrapped onto the outer peripheral surface of the straight body portion in a spiral pattern running parallel to the projection portion so as to cover the outer peripheral surface of the straight body portion.

    摘要: An apparatus for forming an inflatable closing plug has a winding head rotatable around a path defining a winding plane. The winding head is arranged to dispense one or more continuous lines from a supply of line via a guide arrangement. A preform is rotationally supported on an axis at a shallow angle with respect to the winding plane such than the winding plane intersects the preform. By providing a spreading arrangement to locate the windings on the preform over a band having a width perpendicular to the winding plane, a smoother distribution of windings can be achieved.

    摘要: A thread-wound golf ball manufactured by concurrently winding a pair of rubber threads spaced 1-7 mm apart from each other on a core to form a wound core, which is then enclosed with a covering material. The covering material reliably penetrates into a rubber thread layer, thereby achieving an improved bonding strength between the covering material and the rubber thread layer. Durability of the golf ball is enhanced and the time period required for winding threads is considerably reduced, resulting in an improved productivity.
