20080245690 | Flat Packed Mattress Spring Core Assemblies and Method of Packaging Such Assemblies - Package and method of flat-packing multiple pocketed spring core assemblies wherein a stack of multiple pocketed spring assemblies are trapped between a pair of wooden frames. After compression of the stack including the wooden frames, bands are tightly wrapped around the compressed stack. Loops of wire are then inserted through the stack and wrapped about at least one cross element of the frame on each side of the stack. Each loop of wire is pulled taut and its opposite ends connected together so as to prevent the center portion of the stack from ballooning outwardly after removal of compression forces on the rigid frames. | 10-09-2008 |

20090173125 | Method and Apparatus For Creating Stacks of Nested Sinuous Springs - A method and apparatus is disclosed for simultaneously creating a pair of stacks of nested sinuous springs wherein each spring comprises a discrete length of sinuous spring wire having parallel bar wire segments interconnected at their opposite ends by oppositely directed connecting segments. This apparatus includes first and second generally circular forming drums onto which a feeder mechanism is operable to sequentially and alternately pass each of the strips from over a forming mandrel onto the top surface of the first and second generally circular forming drums. A first stripper mechanism is then operable to strip a first one of the arcuate configured strips from over a first one of the forming drums and onto a top surface of a first stacking drum and for stripping a second following one of the arcuate configured strips from over the second forming drum onto a top surface of a second stacking drum. The stripper mechanism is then operable to sequentially and alternately strip following arcuate configured strips from the forming drums onto the first and second stacking drums and over the top of the preceding strips of the stacking drums to create a plurality of arcuately configured springs located on the first and second stacking drums. A second stripper mechanism is then operable after a predetermined number of arcuate strips have been stacked onto each of the first and second stacking drums to strip those stacks from the stacking drums onto a pair of first and second discharge chutes. | 07-09-2009 |
20090260411 | Method and Apparatus For Automating Production of Sinuous Springs - A method and apparatus is disclosed for manufacturing sinuous springs wherein each spring comprises a discrete length of sinuous spring wire having parallel straight bar segments interconnected at their opposite ends by oppositely directed curved connecting segments. This apparatus is operable to adjust the length of the sinuous spring wires exiting the machine without turning off or stopping the machine. An operator need only rotate a handle outside a housing of the machine to increase or decrease the length of the sinuous spring wires exiting the machine. | 10-22-2009 |
20130008555 | SERVO-CONTROLLED THREE AXIS WIRE STRAIGHTENING DEVICE - A wire straightener comprises a wire feed path, a first set of rollers disposed in a first plane along the wire feed path, a second set of rollers disposed in a second plane along the wire feed path, the first and second planes being substantially perpendicular to one another, a first motor operable to adjust a position of at least one of the rollers of the first set of rollers when actuated, and a second motor operable to adjust a position of at least one of the rollers of the second set of rollers when actuated. | 01-10-2013 |
20130239324 | Adjustable Bedding Foundation and Process of Making Same - A bedding foundation used to support a mattress has a mechanism therein for moving the mattress between inclined and flat positions. The foundation combines desirable features of conventional non-adjustable bed bases and adjustable bed bases. A wire assembly and a motorized lift assembly comprising a motorized drive mechanism may be secured to a base of the foundation. The motorized lift assembly pivots a lifter which has two curved portions which function to raise and lower a deck board to incline and lower the mattress. If desired, a second motorized lift assembly may be incorporated into a bedding foundation for use with another deck board. | 09-19-2013 |
20130255823 | Method of Making Border Wire and Apparatus For Practicing Method - An apparatus is provided which makes a border wire having a rectangular cross-section. The apparatus is adapted to receive a roll of wire having a circular cross-section, straighten the wire and change the cross-section of the wire to rectangular. The reconfigured wire is then accumulated, passed through another straightener, cut to size and then bent into a rectangular configuration. Opposed ends of the piece of wire having a rectangular cross-section are welded together to complete the border wire. The apparatus has an ejector which removes the completed border wire from the apparatus. | 10-03-2013 |
