摘要： An apparatus and method for molding a component onto a stretched blank. The apparatus includes a stretching assembly mounted adjacent to a first mold part. The stretching assembly includes a plurality of clamp assemblies that grasp the peripheral edge of the blank and a plurality of slide assemblies that move the clamp assemblies away from one another to apply a stretch to the fabric. The apparatus further includes a press for closing a second mold part onto the first mold part while the fabric is held in a stretched condition by the stretching assembly. In one embodiment, the stretching assembly may include a float plate that is movable with respect to the first mold part between a stretch position and a mold position. The apparatus may include a robot with tooling for moving the fabric onto the stretching assembly. The tooling may include a plurality of shot pins that push the fabric off of the tooling onto corresponding fabric pins in the stretching machine.

摘要： A seating structure includes a support assembly for supporting the body of a user. The support assembly includes a frame member defining an opening and having a channel formed around at least a portion of a perimeter of the opening and an expandable carrier member expandable between at least a first and second configuration. The carrier member is inserted into the channel when expanded to the second configuration. A membrane of elastic material covers the central opening. The membrane has an edge, at least a portion of which is attached to the carrier member. The membrane is stretched a desired amount as the carrier member is expanded between the first and second configurations. A method of assembling a seating structure is also provided.

摘要： A membrane for a seating structure including a plurality of groups of at least two adjacent and parallel strands of multifilament yarn and a plurality of monofilaments arranged in generally perpendicular interlocking relationship with the strands. The monofilaments weave alternatively above and below the adjacent strands in each group. A plurality of pairs of the monofilaments hold the groups of strands in place by having the monofilaments in each pair cross over between each group of strands. In one aspect, the membrane is attached to a frame member such that the plurality of groups of strands are oriented in the longitudinal direction of the frame member and the monofilaments are oriented in the lateral warp direction of the frame member. In another aspect, the seating structure includes the frame member and attached membrane.
