A pneumatic tire for trucks having reduced weight and less material usage. The present invention utilizes an outside-in radial ply construction, which aids to torque the tire bead into the rim of the wheel to which it is mounted and allows the rim to provide greater support for the tire. The size of the bead may be reduced, permitting a reduction in the amount of rubber and reinforcement around and above the bead.

The invention relates to a detachable hemisphere type base body of multiple pressure head board forming device, including a pillar (8), a pressure head (6); one end of the pillar (8) connects to the frame, the other end connects to the pressure head (6); the pressure head (6) is hemispheroid, the working face of the pressure head (6) is plane; a concave sphere support seat (7) is provided between the pillar (8) and the pressure head (6), the sphere portion of the pressure head (6) detachable connects to the concave sphere support seat (7). The pressure head (6) of the base body is not easy to incline when working, the pressing board surface is smooth with little impression.

The invention discloses an adjustable width packaging bag forming device, a bag making device, a packaging machine and a method. The bag making device is included. A traction device and a heat seal device are arranged above the bag making device. A width adjusting device adjusts the distance between different sub bottom plates in a front bottom plate and a rear bottom plate through a lead screw sliding block mechanism, and accordingly bottom plate width adjustment is achieved. The lead screw sliding block mechanism is adopted as the width adjusting device for an automatic adjustable width noodle packaging bag forming device system, the four bottom plates are fixed to the width adjusting device, when the lead screw sliding block mechanism works, the adjusting range is accurate, the adjustable width packaging bag forming device is suitable for multiple widths of packaging bags, and a very important significance is achieved for the three-dimension forming effect of the packaging bags.

One aspect of the present invention can include a friction welding method having a friction step for generating a friction heat by pressing the pair of works (W1,W2) while relatively rotating the pair of works (W1,W2), and an upset step started before generating an approach margin at the pair of works (W1,W2) at the friction step, restricting rotation of the pair of works (W1,W2) relative to each other and applying an upset pressure between the pair of works (W1,W2).

A tire having an outside-in ply construction is provided which torques the tire bead into the rim of the wheel to which it is mounted. The tire has first and second axially-spaced bead cores, a carcass having at least one belt extending under a tread, and a first ply layer having first and second ends. A first end is located axially outside and adjacent a first bead core, and a second end folds from a position axially outside a second bead core to a position axially inside and around the second bead core. The carcass further comprises a second ply layer having first and second ends, a first end is located axially outside and adjacent the second bead core, and a second end that folds from a position axially outside a first bead core to a position axially inside and around the first bead core. The tire may also comprise a first and second axially-spaced bead core, a carcass having at least one belt extending under a tread, and a first ply layer having first and second ends, a first end is located axially outside and adjacent a first bead core, and a second end that is located axially outside and adjacent a second bead core. The carcass further comprises first and second shoulder ply layers each shoulder ply layer having first and second ends, a first end is located under the tread belt, the shoulder ply extending down the side wall region with the second end folding from a position axially outside a respective bead core to a position axially inside and around the bead core.

A cylinder head gasket for an internal combustion engine with a cylinder bore and a fluid hole includes a first metal plate having a curved portion around the cylinder bore and a folded portion extending from the curved portion, and a second metal plate laminated on the first metal plate and having a first full bead projecting toward the first metal plate. The first full bead is disposed on the folded portion. At least one secondary plate is inserted inside the folded portion.
