The production, by either a batch process or a continuous process, of vehicle seat trim pads or like articles of cured polymer no-gel latex foam and having convex or crowned surfaces free of congealed polymer skin, is disclosed. In the process, a backing fabric is first laid on a pervious supporting surface. A no-gel latex foam is then deposited on the fabric, and an open-bottom open-top grid of a height not greater than that of the deposited mass of latex foam is placed into the latter, excess latex foam above the top plane of the grid being scraped off to impart to each pocket or island of foam a smooth and level top surface. The entire assembly is then subjected to dry heat to effect both a rapid dehydration and a curing of the latex foam. During the initial stage of this operation, the no-gel latex foam expands somewhat so that the top surface of each island thereof becomes crowned without having to be disposed in contact with a mold surface of appropriate contours. The grid is removed after curing has been completed, leaving a plurality of in situ formed channels separating the base-connected islands. An upholstery covering is then applied to the top surface of the finished pad in closely conforming relation to the crown surfaced islands, being secured to the pad by stitching through the bottoms of the channels. This abstract is not to be taken either as a complete exposition or as a limitation of the present invention, however, the full nature and extent of the invention being discernible only by reference to and from the entire disclosure.

摘要:
A method of making a foam cushion for use as a seat, mattress or the like including the steps of foaming a material in an open top mold to form a cellular pad having a dense upper crust, and supportingly positioning an open mesh fabric and an overlying spring assembly in floating relation on the foaming material. The open mesh fabric thereby becomes essentially embedded in the crust to reinforce the same, and the terminal face portions of the spring assembly are adhered to the crust to interconnect the various components. To form an innerspring mattress, the resulting structure is removed from the mold, inverted, and positioned on additional foaming material in a like manner. In a further embodiment, the spring assembly is positioned on the pad after the foaming process is completed. In this case, the originally unattached foam pad may be easily stored or shipped to a point of assembly where the spring assembly is later joined by hog ringing or the like. In order to densify the foaming material in this latter embodiment, a screen member having a weight and outline generally similar to that of the spring assembly may be removably positioned on the foaming material during the foaming process.

An improved method for making three- or four-way taper pillows from a web of soft compressible material that is folded into a batt and encased in a pillow tick. This is accomplished by folding the web along first fold lines to produce a multi-ply web having a plurality of superimposed plies located between opposite edges while positioning some of the fold lines between the opposite edges such that there are a greater number of plies along the center of the multi-ply web then at the opposite edges and subsequently folding the multi-ply web along second fold lines extending perpendicular to the opposite sides of the multiply web to produce a pillow batt having a plurality of layers each having a plurality of plies. The batt is then enclosed in a pillowed tick by compressing the peripheral edge to produce a completed pillow. In one embodiment, a three-way tapered pillow is produced by locating all of the fold lines along one edge of the layers in a common plane while the fold lines along the opposite edge are staggered relative to each other and in an alternative embodiment a four-way taper is produced by staggering the fold lines of the layers along both edges.

A METHOD OF AND AN APPARATUS FOR APPLYING TWO-PART DOUBLE BOLSTER BUTTONS OF SYNTHETIC MATERIAL CONNECTED TOGETHER BY A STAY-PART, AND TWO-PART HOLLOW RIVETS OR THE LIKE EQUIPPED WITH BOLSTER BUTTONS AND SERVING AS A STAYPART IN BOLSTERS, MATTRESSES, CUSHIONS AND THE LIKE, WHICH COMPRISES THE STEPS OF STRONGLY COMPRESSING AND RIGIDLY CLAMPING A BOLSTER ABOUT THE POSITION OF A DOUBLE BOLSTER BUTTON, AND PUNCHING THE BOLSTER AT THE POINT OF THE BOLSTER BUTTON TO BE INSERTED. A SMALL TUBE SLIDES OVER THE SHAFT OF A MANDREL BEHIND CUTTING EDGES OF THE MANDREL AND THE LATTER IS WITHDRAWN THROUGH THE SMALL TUBE AND THE MANDREL AND IS REMOVED FROM THE BOLSTER. A STAY-PART OF ONE PORTION OF THE DOUBLE BOLSTER BUTTON OR OF A HOLLOW RIVET IS INSERTED INTO THE SMALL TUBE ON THE SIDE REMOTE FROM THE MANDREL. THE SMALL TUBE IS THEN WITHDRAWN AND THE OTHER PORTION OF THE DOUBLE BOLSTER BUTTON OR THE RIVET EQUIPPED WITH A BOLSTER BUTTON SLIDES AND IS SECURED ONTO THE FIRST PORTION OF THE BOLSTER BUTTON ALREADY IN THE BOLSTER, AND THE CLAMPING OF THE BOLSTER IS RELEASED.
