Mattress constructions and apparatus for producing the constructions wherein a resilient filler is located in a hopper and a flexible mattress cover is positioned for communication with the open end of the hopper. Means are provided for driving the filler into the cover, and the apparatus provides adhesive dispensers which apply adhesive to the filler surfaces so that this adhesive forms a bond between these surfaces and the associated cover. The apparatus employs engaging members for driving the filler out of the hopper, the engaging members automatically accommodate to differences in filler widths and thicknesses so that proper pushing engagement with the filler is reliably achieved. The resulting mattress is provided with a secure adhesive bond between the cover and filler, avoiding movement between the cover and filler during handling and use.
In an apparatus for filling a flexible cover with a resilient filler for the formation of mattresses or the like, said apparatus including a hopper defining a filler receiving space and an open end, said cover being dimensioned for attachment to the hopper whereby the interior of the cover communicates with said open end of the hopper, and means for driving said filler into said cover, the improvement comprising adhesive dispensing means positioned on said hopper, at least one surface of the filler being located adjacent said dispensing means when the filler is in the hopper, and means for operating said dispensing means during movement of the filler into the cover whereby adhesive is deposited on the filler surface for contact with an opposed cover surface whereby the cover is adhered to the filler.
In an apparatus for filling a flexible cover with a resilient filler for the formation of mattresses or the like, said apparatus including a hopper defining a filler receiving space and an open end, said cover being dimensioned for attachment to the hopper whereby the interior of the cover communicates with said open end of the hopper, and means for driving said filler into said cover, the improvement wherein said means for driving said filler comprises a pair of spaced apart filler engaging members adapted to assume a first position in the hopper spaced from said open end, drive means connected to said engaging members for moving the members toward said opened end, and resilient means interposed between said members for forcing the members apart and toward the hopper walls.
