A nailing machine for assembling wood pallets includes a nailing station and an advancement and guiding component which form a substantially horizontal resting surface at the nailing station configured for the assembly of at least two superimposed wood pieces to be assembled by nailing to provide a pallet. The nailing station includes at least one nailing head, each of which is associated with at least one nailing stem, which can move along a substantially vertical direction with respect to the resting surface between an inactive position, in which the lower end of the nailing stem is spaced from the upper surface of the superimposed wood pieces, and an active position, in which the lower end of the nailing stem is moved closer to, or made to penetrate, the upper surface of the superimposed wood pieces.

An insertable fastener installation apparatus for a flat substrate has a thickness, T. A roller press station is used to press T-nuts into holes in the substrate. An optical vision system detects the location of the holes in the moving substrate and aligns the t-nuts with the holes. A computer controlled pick and place robot takes T-nuts from an escapement of a hopper feed system and aligns, but does not fully insert, the t-nuts in the substrate. A conveyor system feeds the substrates through the optical vision system, the pick and place robot station and the roller press station. A first roller is spaced apart from a second roller by a gap in the roller press station and the gap is less than the thickness of the substrate. The hopper feed system includes a bulk hopper, a bowl, a track and an escapement.

An axial section of a continuous portion where an outer peripheral surface of a spindle portion of a main spindle in which a punch is installed is continuous with an outer peripheral surface of a punch holder is formed of a first circular arc joined to the outer peripheral surface of the spindle portion and a second circular arc joined to the outer peripheral surface of the punch holder. The first circular arc and the second circular arc are in contact with each other. The second circular arc is smaller than the first circular arc in curvature radius.

In a joining method for joining a first plate material and a second plate material b screwing a self-tapping screw from one direction in a state where the first plate material and the second plate material are put on top of each other, a recessed portion is formed in at least one of the first plate material and the second plate material, and in a state where the first plate material and the second plate material are put on top of each other such that the recessed portion is opened in a contacting face between the first plate material and the second plate material, the self-tapping screw is screwed from the one direction. When the self -tapping screw penetrates through the first plate material due to the screwing of the self-tapping screw, an excess part generated from the first plate material flows into the recessed portion.

A joining method is a method of joining a plate set composed by a plurality of stacked plate members including a first plate member and a second plate member by using a tapping screw. When the tapping screw is advanced into the plate set while the tapping screw is rotated in a state of applying a pressure onto the plate set so as to form through-holes in the first plate member and the second plate member, a first pressure applied onto the tapping screw is reduced down to a second pressure at the time when the tapping screw penetrates the first plate member.

A hole punch and a method for piercing a workpiece wherein a hole punch includes a sheet metal part and a piercing body attached thereto which carries out the piercing function and which is provided with a thread cylinder or can be provided with a thread cylinder, for example by pressing a threaded pin into a centrally arranged passage of the hole punch, wherein the hole punch can also be formed in one piece as a piercing body with a sheet metal-like flange. Furthermore a method is claimed for the manufacture of the hole punch.

A fencing system that includes a plurality of fence rails extending between two fence posts. The fence rails may comprise a foamed material core that is enclosed by a weather resistant capping material. One or more hollow passageways may be formed in each of the fence rails to both reduce weight and to receive a metal reinforcing member. A plurality of fence pickets may be installed onto the fence rails using power driven fasteners, such as ring shank nails or staples.

A wooden pallet includes a base layer, and a cargo layer. The cargo layer includes a pair of spaced apart connector boards, and a pair of spaced apart end deck boards orthogonal to the pair of connector boards. Respective ends of the pair of end deck boards overlap respective ends of the pair of connector boards. Nail plates are coupled between the respective ends of the pair of connector boards and the respective ends of the pair of end deck boards. Each nail plate has a first surface having projections extending outwards therefrom and embedded into one of the end deck boards, and a second surface opposite the first surface devoid of any projections and contacting an end of one of the connector boards. Spaced apart support blocks are between the base layer and the pair of connector boards in the cargo layer, and form a gap therebetween for receiving a lifting member.

An arrangement of components, in particular for a vehicle seat, includes a first component and a second component which are interconnected by a connector. The connector includes a nail-shaped pin that has a grooved drive stud.
