In order to manufacture an innerspring unit comprising pocketed springs and having an increased stability at its edge regions, in a first step, an innerspring main body comprising a plurality of first strings of pocketed springs is provided. In a subsequent second step, at least one second string of pocketed springs is attached to a lateral surface of the innerspring main body, so that the at least one second string of pocketed springs extends in a longitudinal direction of the innerspring main body. The springs of the at least one second string of pocketed springs have a spring characteristic or a spring geometry different from the springs of the plurality of first strings of the innerspring main body. The at least one second string of pocketed springs forms together with the innerspring main body the innerspring unit.

Methods and systems for no-glue pocketed spring unit construction. Rows of pocketed springs, preferably arranged into modules of more than two pocketed springs surrounding a central hole, are ultrasonically welded together when paired vibrating probes and anvils press layers of pocketed spring fabric from the rows of pocketed springs together and a welding pulse is transmitted to the vibrating probe.

Components of a pocket-sprung-mattress sub-assembly having individual metal springs retained within a matrix of fabric pockets are separated. A rotatable tearing drum 405 is driven by a drive motor 406. Tearing devices 407 are arranged to pull metal springs from a pocket-sprung-mattress sub-assembly during the rotation of the tearing drum 405. A feeding assembly 408 compressors an end portion of the mattress sub-assembly and moves this end portion continually to bring an end of the mattress sub-assembly into contact with the rotating tearing devices 407.

A method and apparatus for deconstructing a mattress of the type having steel coil springs held within fabric pockets. The apparatus includes a frame and an opener mechanism mounted to the frame and operable for opening a plurality of fabric pockets at a first end thereof to create an opening in the first end of the fabric pockets and expose the steel coil springs contained therewithin. A gripper mechanism is provided for gripping the plurality of fabric pockets at a second end thereof, opposite the first end. An extractor mechanism is mounted to the frame for extracting the steel coil springs from the fabric pockets through the openings formed in the first end of the fabric pockets.

Apparatus for manufacturing pillows, comprising: at least one first bobbin of a first fabric and a second bobbin of a second fabric, means adapted to place the first fabric on the second fabric along their advancement path, means configured to drag the fabrics, a pair of side welding devices for welding the side edges of first and second fabrics, a transverse welding device adapted to weld the fabrics found in a tubular envelope transversally to the advancement path for forming a pillowcase, a press for pressing the first fabric onto the second fabric when the length of the pillow reaches the desired length, means adapted to insert material inside the pillowcase, means for cutting the fabrics welded by the transverse welding device to separate the pillow from the successive pillow.

A device for producing an edge strip may have a supply unit with at least two openings for separately supplying an edge strip core and a material strip of a casing for the edge strip core. The material strip may be provided with a decorative element, an adapter unit, and a processing unit. The supply unit arranges the edge strip core on a surface side of the material strip which forms the inner face of the casing, and the adapter unit is designed to fold the material strip around the edge strip core. Free ends of the casing protrude from the edge strip core and lie one over the other, and the processing unit connects the free ends lying one over the other together. A method for producing an edge strip using such a device and to a seat cover with an edge strip is also included.

Apparatus for manufacturing pillows, comprising: at least one first bobbin of a first fabric and a second bobbin of a second fabric, means adapted to place the first fabric on the second fabric along their advancement path, means configured to drag the fabrics, a pair of side welding devices for welding the side edges of first and second fabrics, a transverse welding device adapted to weld the fabrics found in a tubular envelope transversally to the advancement path for forming a pillowcase, a press for pressing the first fabric onto the second fabric when the length of the pillow reaches the desired length, means adapted to insert material inside the pillowcase, means for cutting the fabrics welded by the transverse welding device to separate the pillow from the successive pillow.

A pocketed spring assembly comprises a plurality of parallel strings of individually pocketed springs. A dimensionally stabilizing substrate is secured to at least some of the strings on one of the top and bottom surfaces of the strings. A scrim sheet is secured to at least some of the strings on an opposed surface of the strings to maintain the positions of the strings. The dimensionally stabilizing substrate is laterally rigid enough to maintain length and width dimensions of the coil spring assembly. However, the dimensionally stabilizing substrate is flexible enough to allow the pocketed spring assembly to be roll packed for shipping.

A system may include an access engine and a foam part generation engine. The access engine may be configured to access a computer-aided design (CAD) seat surface that represents a seat surface of a seat design and access seat parameters for the seat design. The foam part generation engine may be configured to construct a CAD foam part for the seat design based on the CAD seat surface and the seat parameters.

An apparatus for bonding and combining a pocket spring bed mesh and method, and a pocket spring bed mesh. The apparatus includes a rack, a platform arranged on the rack for driving the pocket spring bed mesh to move reciprocally, a rotating mechanism used for driving the pocket spring bed mesh to rotate, and a combining mechanism used for combining pocket spring strings to form the pocket spring bed mesh. The combining mechanism bonds and combines pocket spring strings to form an unshaped pocket spring bed mesh which is driven by the platform to move to the position of rotating mechanism to be rotated for adjusting the orientation, then the pocket spring bed mesh is moved by the platform to the combining mechanism, and the combining mechanism bonds and combines the side parts of the unshaped pocket spring bed mesh using a pocket spring string of a smaller diameter.
