Apparatus for bonding fabric to seat cushion trenches
First Claim
1. A bonding assembly (10) for bonding portions of a fabric bag (12) to a seat cushion assembly (14) so the fabric bag (12) may be manipulated to remove any wrinkles in the fabric bag (12) prior to bonding the fabric bag (12) to the seat cushion assembly (14), said bonding assembly (10) comprising:
- base means (16) for positioning a seat cushion assembly (14) within a fabric bag (12) to be bonded thereto;
tubing means (28) for providing a passageway for fluids to pass therethrough, said tubing means (28) movable to a compressing position, said bonding assembly (10) characterized bysaid tubing means (28) including a plurality of tubes (30) disposed apart from each other such that portions of the fabric bag (12) located between each of said plurality of tubes (30) may be manually adjusted while said plurality of tubes (30) is compressed against the fabric bag (12) and seat cushion assembly (14) prior to bonding portions of the fabric bag (12) under said plurality of tubes (30) to the seat cushion assembly.

Abstract
The assembly (10) includes a plurality tubes (30) configured to fit into the trenches of a preformed seat cushion assembly (14). The plurality of tubes (30) rotate about pins (56) and force a fabric bag (12) and an adhesive layer located between the seat cushion assembly (14) and the fabric bag (12) into the trenches. Steam passes through the plurality of tubes (30) and out a plurality of holes (32) which are spaced along the plurality of tubes (30). The steam melts the adhesive layer which subsequently bonds the fabric bag (12) to the seat cushion assembly (14) within the trenches of the seat cushion assembly (14). A vacuum (40) is used to create a pressure differential between the passageways within the plurality of tubes (30) and the atmosphere, i.e., the seat cushion (15). The pressure differential is used to remove the steam and any water from the fabric bag (12) and seat cushion assembly (14) to prevent water damage thereto.
