A press, carried by a first table and having punch and die components, receives a rectangular filler sheet and forms a lateral accordian fold sheet. The accordian fold sheet is lifted from the press by transfer means and placed upon an envelope sheet overlaying a second table. Hinged panels carried by the second table fold the envelope sheet over the accordian fold sheet, forming a rigid compartmentalized panel having an opening along a longitudinal edge. The second table, with the opening upright, moves to a position under a receptacle from which granular loose fill material is entered into the compartments through the opening. Subsequently, flaps extending along the panels move to further fold the envelope sheet and close the opening.

An apparatus for receiving selected components including, a rectangular filler sheet having a pair of parallel longitudinal edges, a pair of parallel lateral edges, and a pair of opposed faces, an envelope sheet having a pair of opposed faces, and a supply of granular loose fill insulative material,
An apparatus for receiving selected components including, a rectangular filler sheet having a pair of parallel longitudinal edges, a pair of parallel lateral edges, and a pair of opposed faces, an envelope sheet having a pair of opposed faces, and a supply of granular loose fill insulative material, said insulative material being of the type conventionally intended for pneumatic or poured application on horizontal surface installations, and for fabricating a rigid insulative panel from said components, said apparatus comprising: a base; a press supported by said base for receiving said filler sheet and impressing selected lateral sections thereof to form a laterally folded sheet therefrom, wherein said press includes: (a) a die for receiving said filler sheet and having a plurality of spaced apart die elements defining a plurality of spaced apart recesses therebetween; (b) a punch having a plurality of spaced apart punch elements extending therefrom, said punch elements being matingly receivable within said recesses between said die elements; and (c) means for moving said punch relative said die and for urging said punch elements into said recesses for impressing lateral portions of said filler sheet into said recesses and forming said folded sheet wherein said punch elements extend longitudinal of said punch, said punch being carried by a guide means for movement relative said die, said guide means includes: (a) a frame movable along said press and secured against upward movement therefrom; and (b) biasing means urging said punch elements downwardly against said die a table supported by said base for receiving said envelope sheet and said folded sheet; first and second rectangular panels, each having inner and outer longitudinal edges, first and second lateral edges, and an inner face, said inner longitudinal edges being spaced apart and hingedly mounted on said table, said first and said second panels being contractively movable to fold said envelope sheet against the faces of said folded sheet to form a partitioned structure having an open top, a pair of lateral flaps, one hingedly secured along either lateral edge of said second panel and inwardly movable to fold said envelope sheet against a respective lateral edge of said folded sheet, including a longitudinal flap hingedly secured along the outer longitudinal edge of said second panel and inwardly movable to fold said envelope sheet and close said opening, including: (a) marginal anvil portions carried proximate the outer longitudinal edge and the first and second lateral edges of said first panel, said anvil portions extending beyond the respective edges of said folded sheet; and (b) an abutment member carried by each of said flaps for pressing the respective marginal portion of said envelope sheet against the respective anvil portion; a receptacle for holding said supply and loose fill insulative material; and filler means cooperating between said receptacle and said partitioned structure for depositing said insulation into said structure through said open top.
