A wire mesh rivet (13) is provided which is used to produce a wire mesh isolator (11) in a bore (9) of a substrate such as a heat shield (7) for a vehicle exhaust system. The rivet (13) comprises a unitary wire mesh structure (19) which has a collar (15) and a shank (17). The collar (15) has a higher density than the shank (17), e.g., the collar (15) has the density of the finished isolator (11). The rivet (13) is formed into the finished isolator (11) by compressing the shank (17) to form a second collar, while restraining the original collar (15) from substantially changing its shape. The rivet (13) can include a metal insert (23) which prevents the wire mesh of the finished isolator (11) from experiencing high levels of compression when the substrate is fastened to its supporting structure. The rivets (13) can be carried by a dispensing strip (31) and can be formed into the finished isolator (11) using forming equipment (39) whose dimensions are compatible with the limited space available with some substrates.

A continuous coil string staging system is provided herein that includes at least one coiler configured to output at least one continuous coil string, at least one assembler configured to assemble the at least one continuous coil string into a mattress assembly, and at least one coil string staging apparatus disposed between the at least one coiler and at the least one assembler. The at least one coil string staging apparatus can have an input, a staging buffer, and an output such that the coil string staging apparatus receives the at least one continuous coil string that is output from the at least one coiler and outputs the at least one continuous coil string to the assembler such that there is a buffer of coil string available to the assembler. Various coil string staging apparatuses and methods are also provided herein.

A cutting apparatus for an elongate wire is provided, and includes a housing that supports a first cutter that has a body, a recess, and a cutting blade. The cutting blade is disposed upon a wall of the body that defines the recess, the first cutter is fixed with respect to the housing. The housing additionally supports a second cutter that has a body, a recess, and a cutting blade, wherein the cutting blade is disposed upon a wall of the body that defines the recess. The second cutter is normally positioned with respect to the first cutter such that the recess of the first cutter is aligned with the recess of the second cutter, and is movable to a second position where the recess of the second cutter translates with respect to the recess of the first cutter, such that the respective cutting blades translate toward each other.

A metal lath having an integral hem structure includes a main body. The main body is formed by enclosing the metal lath so that the main body has a ring-shaped side wall. The side wall defines an accommodating space therein. Two ends of the main body are formed with openings to communicate with the accommodating space, respectively. One of the openings is integrally formed with a hem around an end edge of the opening by bending. The hem is integrally formed with the metal lath, which can reduce production time and cost effectively and can prevent the user from being cut by the metal lath.

A device comprises at least two shaping cylinders each comprising a multitude of protrusions radially extending outward from the cylinder. The device further comprises a first drive unit for driving unit for driving at least one of the first shaping cylinder and the second shaping cylinder, a device frame arranged to support the first shaping cylinder and the second shaping cylinder in a rotating fashion such that the multitude of first protrusions is arranged to engage with the multitude second of protrusions and a biasing module arranged to apply a biasing force to at least one of the shaping cylinders. In this device, the biasing module, the first protrusions and the second protrusions are arranged such that when netting is provided between the shaping cylinders, the netting is force fitted between the shaping cylinders at substantially each rotational position of the shaping cylinders.

For forming a multi-layer strand of pocketed springs, a first strand (11) of pocketed springs (21) and a second strand of pocketed springs (22) are connected to each other. For this purpose a first pocketed spring (21) of the first strand (11) is aligned in a coaxial manner with a second pocketed spring (22) of the second strand (12) so that a first seam portion (31) of pocket material at an end of the first pocketed spring (21) overlaps with a second seam portion (32) at an end of the second pocketed spring (22), and the first seam portion (31) is welded to the second seam portion (32), e.g., using ultrasonic welding.

An apparatus for manufacturing a second mesh roll from a first mesh roll is disclosed. The apparatus comprises an unreeling shaft, an edge treatment unit, and a reeling shaft. The unreeling shaft is configured to rotatably support the first mesh roll and provide an unreeled length of the first mesh roll in a longitudinal direction. The edge treatment unit is configured to receive the unreeled length of the first mesh roll and cut the first mesh roll along a transverse axis and treat one or more edges of the first mesh roll to form the second mesh roll. The reeling shaft is configured to receive and rotatably support the second mesh roll.

A rebar tying robot configured to tie a plurality of first rebars and a plurality of second rebars intersecting the plurality of first rebars at points where the plurality of first rebars and the plurality of second rebars intersect. The rebar tying robot may include a rebar tying machine, a conveying unit configured to convey the rebar tying machine, and a control unit configured to control an operation of the conveying unit. The conveying unit may include a crawler configured to move on the plurality of first rebars and the plurality of second rebars.
