摘要： A method of forming a laminate composed of a solid polyester lamina bonded to a block. A block having a matrix composed of polyurethane foam and particles of expanded polystyrene distributed therein is prepared. A layer composed of a solution of a relatively unpolymerized polyester in styrene solvent with fiberglass embedded therein is placed in contact with a surface of the block. The styrene solution of polyester dissolves polystyrene particles adjacent such block surface, leaving recesses distributed in the block matrix. These recesses become at least partially filled with the polyester solution. The solution is then cured to produce a solid resin lamina which is joined with polymerized resin contained in the matrix recesses to secure the lamina to the block.

摘要： An in-line method of forming a laminate of a heat sensitive foam sheet material, and a hot extruded polymeric product comprising hot extruding a polymeric material into a shaped product and while still hot contacting the shaped product with a face of the heat sensitive foam sheet material and thereafter cooling the resulting product. Such face is previously coated with a layer of a heat sealing substance which is activated at a temperature below the softening point of the heat sensitive foam sheet. The heat seal contact takes place under minimal pressure when the surface temperature of the shaped product is still high enough to activate the heat sealing substance but not high enough to damage the heat sensitive sheet. The laminates so made are part of the invention.

摘要： A non-woven rug, or the like, is formed by heat sealing a covering material at spaced intervals to a plastic backing and thereafter shrinking the backing to bulk the facing fabric. The heat sealing of the facing fabric to the backing causes a partial loss of orientation in the seal area therein bringing about a bulking or crinkling of the backing. The backing is preferably of a thermoplastic material having a foaming agent incorporated therein which is foamed after the completion of the heat sealing and heat shrinking procedures. Also included in the disclosure are the features of the backing fabric independently, i.e., incorporation of a foaming agent into a plastic which is extruded and thereafter heat sealed and/or stretch oriented and shrunk prior to the activation of the foaming agent to foam the fabric.

摘要： A method of forming a self-supporting contoured foam plastic laminate, including spraying a relatively flexible open cell plastic foam, preferably polyurethane, on a sheet which is to become part of the laminate, applying a second sheet over the foam layer and promptly forming the contoured laminate under pressure in a die. The disclosed laminate includes a corrugated paper sheet, wherein the corrugations extend into and are bonded to the foam layer and a relatively flexible finish sheet bonded to the foam layer. In the disclosed automotive headliner, the corrugations extend perpendicular to the headliner side edges, providing support for the concave midportion of the headliner and preventing delamination of the paper and foam laminae.

摘要： A shaped synthetic resin article varying in cross-sectional area and shape of longitudinal section along at least a part of the length is continuously produced by introducing a molten synthetic resin composition, extruded from an extruder die, between at least one pair of rolls rotating in the direction of extrusion so that the rolls of each pair contact each other on their periphery, the peripheral surfaces of the rolls being engraved so as to form a cavity corresponding to the shape of said shaped article when the rolls of each pair contact each other while being rotated, in which cavity the molten resin composition is remolded into an article having the desired shape and at the same time the surplus resin composition overflowing from said cavity is cut off by the edges of said rolls contacting each other, and then cooling the molded article to solidify the same. According to the above process, the diameter of the minimum cross-section of the article can be made much smaller than the outer diameter of the die or nozzle.
