A mechanism (300) for transferring coil springs from a coil winding device (110) to a conveyor belt (210) of a pocketed coil assembly machine comprises a magnetic lift platform (310) for engaging a coil spring (10) before being released at an output of the coil winding device (110). Further, the mechanism comprises a drive mechanism (315) for moving the lift platform (310) between the output of the coil winding device (110) and the conveyor belt (210).

A method to manufacture a steel wire spring core for a mattress or for seating is described, which comprises the steps of providing a carrier comprising steel wire; repeatedly cold coiling a steel wire spring from steel wire taken from the carrier; and connecting a series of the coiled steel wire springs to each other. The steel wire has a diameter d between 0.8 and 4.5 mm; and has a drawn pearlitic microstructure. The steel wire comprises a steel alloy having a carbon content between 0.35 wt % and 0.85 wt %. The steel wire on the carrier has a ratio—expressed as a percentage—of the yield strength R.sub.po 2 (in MPa) over the tensile strength R.sub.m (in MPa) higher than 85%.

Further, the mechanism comprises a drive mechanism (315) for moving the lift platform (310) between the output of the coil winding device (110) and the conveyor belt (210).

An apparatus for assembling a bedding foundation having spring modules and a frame includes a support configured to receive the frame, a bridge disposed over the support, and staplers movably coupled to the bridge and positioned over the support, each stapler configured to staple a spring module to the frame. The apparatus also includes cameras coupled to the bridge and positioned over the support. Each stapler is operatively associated with one of the cameras and each camera is positioned to provide a field of view toward the support. The apparatus also includes a driver configured to move the frame relative to the support and a controller in communication with the cameras and the driver, the controller configured to receive vision guidance signals from one of the cameras to direct movement of the driver and of the stapler operatively associated with the one of the cameras.
