发明名称 Method for manufacturing a separable fastener for incorporation into a seat bun
摘要 In a device for incorporating a separable fastener in a foamed seat cushion during formation of the cushion in a mold, includes a sheet having fastener elements constituting one half of a touch fastener. A foam wall surrounds the fastening surface, the wall having a height considerably greater than the height of the fastening elements. The fastener is held on a pedestal having a predetermined height extending into the mold volume and having a predetermined cross sectional dimension generally parallel to the interior mold surface as measured at a predetermined distance from said mold surface. The foam wall defines an opening which engages the sides of said pedestal with a force sufficiently strong to resist any removal force caused by tendency of the foaming action to lift the foam wall during creation of the cushion and bonding of the forming cushion to the foam wall.
