The present invention relates to an apparatus for manufacturing reinforcement meshes and spinning stations therefor. Reinforcement rods to be joined with the spinning wires are supplied by advancing means from the rear end of the apparatus, and a special mechanism prevents that the wire breaks during its encounter with the reinforcement rod.

An apparatus for working bars includes a plurality of containing devices disposed adjacent and parallel to each other with an oblong development in respective longitudinal directions to contain a respective bundle of bars. At least one work station is located downstream of the containing devices. The work station includes at least one removal device to remove at least one bar from one of the containing devices, at least one drawing unit configured to move the bars in a direction of feed parallel to the longitudinal directions, and at least one bending device configured to bend the bars At least one drive member is associated with the work station, configured to move work station in a transverse direction with respect to the longitudinal directions in order to take the removal device into correspondence with one or the other of the containing devices, which are substantially fixed in position.

An exemplary embodiment provides a method of manufacturing a string of pocketed spring coils comprising: simultaneously making at least two spring coils; simultaneously transporting the at least two spring coils to a compressor: simultaneously compressing the at least two spring coils; simultaneously inserting the at least two compressed spring coils between top and bottom plies of a piece of fabric; welding the top and bottom plies of the fabric along an edge of the folded fabric parallel to the longitudinal axis of the fabric and opposite the folded edge of the fabric; welding the top and bottom plies of the fabric along lines transverse to the longitudinal axis of the fabric between each of the compressed spring coils to create a plurality of pockets, each pocket encompassing a compressed spring coil; and expanding each of the compressed spring coils within each of the plurality of pockets.

A system for manufacturing a string of pocketed coil springs comprising: a coil-forming subsystem that produces two coil springs; a spring transporter subsystem that receives the two coil springs at a first position and conveys the two coil springs to a second position; a spring compressor subsystem that compresses the two coil springs; a fabric-folding subsystem that receives a piece of fabric and folds the fabric to create an open side; a spring inserter subsystem that receives the two compressed coil springs and inserts the two compressed coil springs between top and bottom surfaces of a folded piece of fabric; two welder subsystems that form first and second welds between top and bottom surfaces of the folded piece of fabric, the first welds and the second welds forming a plurality of pockets in the fabric, each of the plurality of pockets comprising a compressed coil spring.

Apparatus for handling bars (31), in particular metal bars, including a loading unit (22) provided with transporter elements (25) to transfer a series of bars (31) toward a selector unit (34); the selector unit (34) includes a gripping device (35) configured to remove one or more bars (31) from the transporter elements (25) of the loading unit (22) and to release them toward a subsequent collection station (43) and also includes sensors (41) configured to automatically detect at least the number of bars (31) removed and released by the gripping device (35) toward the collection station (43).

A linear member gripping device includes: a first gripping member that abuts a linear member; a second gripping member that abuts the linear member and has a protrusion; a first drive part and a second drive part that change relative positions of the first and second gripping members; and a limitation part that limits movement of the linear member sandwiched between the first and second gripping members at a predetermined limitation position.

Apparatus to bend bars, comprising: a bending unit (35) of at least one bar (B, B′) and a drawing unit (46) configured to define at least a direction of feed (A) of the bar (B, B′) to the bending unit (35). The bending apparatus is provided with: a support plane (11) on which the bars (B, B′) to be bent are put; a removal unit (19) to remove at least one bar (B, B′) from the support plane (11), a feed unit (33) configured to receive the bar (B, B′) removed by the removal unit (19) and to transfer it to the drawing unit (46).
