Abstract
Apparatus and a method for assembling a stretchable cover upon a rigidly backed foam cushion wherein the cushion lateral dimensions vary along its length. The degree of stretching of the cover varies during cushion/cover assembly as controlled by cams and cam followers to permit wrinkle-free covering of backed foam cushions of irregular configuration.
Claims14
A method of assembling a foam cushion assembly, comprising the steps of:
- placing a cushion cover inside-out over cantilevered stanchions wherein said cushion cover defines a pocket between said stanchions;
- inserting a foam cushion into said pocket between said stanchions;
- and
- simultaneously stretching said cushion cover laterally to an extent determined by the lateral dimensions of the foam cushion while continuing to insert said foam cushion into said pocket between said stanchions until the foam cushion is completely received within said pocket of said cushion cover to form said foam cushion assembly.

A method of assembling a foam cushion assembly, comprising the steps of:
- releaseably mounting a foam cushion to a reciprocally movable ram;
- providing two pair of similar plate-like stanchions wherein each stanchion of each pair of stanchions is substantially parallel to one another thereby forming a gap therebetween, and each pair of stanchions laterally movable toward and away from one another;
- placing a cushion cover inside-out over said two pair of stanchions wherein said cushion cover defines a pocket between said stanchions;
- inserting said foam cushion into said pocket of said cushion cover by moving said ram toward said pocket of said cushion cover;
- and
- simultaneously stretching said cushion cover laterally to an extent determined by the lateral dimensions of the foam cushion by moving each of said pair of stanchions laterally away from one another while continuing to insert said foam cushion into said pocket between said stanchions until said foam cushion is completely received within said pocket of said cushion cover to form said foam cushion assembly.

A method of assembling a foam cushion assembly, comprising the steps of:
- releaseably mounting a wooden backed foam cushion to a reciprocally movable ram;
- providing two pair of similar plate-like stanchions wherein each stanchion of each pair of stanchions is substantially parallel to one another thereby forming a gap therebetween, and each pair of stanchions laterally movable toward and away from one another;
- placing a cushion cover inside-out over said two pair of stanchions wherein said cushion cover defines a pocket between said stanchions;
- inserting said foam cushion into said pocket of said cushion cover by moving said ram toward said pocket of said cushion cover;
- camming said stanchions to laterally move said pair of stanchions relative to one another;
- simultaneously stretching said cushion cover laterally to an extent determined by the lateral dimensions of the foam cushion by moving each of said pair of stanchions laterally away from one another while continuing to insert said foam cushion into said pocket between said stanchions until said foam cushion is completely received within said pocket of said cushion cover to form said cushion assembly;
- moving said ram away from said pocket of said cushion cover after said foam cushion reaches the bottom of said cushion cover to form said foam cushion assembly;
- and
- simultaneously moving an ejector rod to engage and remove said foam cushion assembly from between said stanchions when said ram begins to move away from said pocket of said cover.
