Method of manufacturing a laminated soft good
A layered stack is created by placing webs of adhesive on opposite sides of web of cushioning layer and placing outer webs outside the webs of adhesive. An outer surface of a rotating drum is heated by heating oil inside the drum. An endless belt is heated by at least one heater. The layered stack is pulled between the heated endless belt and the heated rotating drum via a motorized drive assembly which rotates the endless belt. Both sides of the layered stack are heated enough to melt each web of adhesive when the layered stack passes between the heated moving endless belt and the heated rotating drum.
1. A method of manufacturing a laminated soft good, said method comprising:
creating a layered stack comprising a cushioning layer, webs of adhesive on opposite sides of the cushioning layer and outer layers outside the webs of adhesive;
heating an endless belt with a radiant heater;
moving the heated endless belt via a motorized drive assembly thereby pulling the layered stack between a heated rotating drum and the heated moving endless belt downstream; and
heating both sides of the layered stack by passing the layered stack between the heated moving endless belt and the heated rotating drum, heat from the heated endless belt and the heated rotating drum laminating the cushioning layer to the outer layers to create a laminated soft good.
2. The method of claim 1 , wherein the radiant heater is below the heated endless belt.
3. The method of claim 1 , wherein one of the outer layers contacts the heated rotating drum and the other outer layer contacts the heated endless belt.
4. The method of claim 1 , wherein moving the heated endless belt via a motorized driver includes using a motor to rotate a drive roller.
5. The method of claim 1 , wherein compressing the layered stack comprises passing the layered stack between an adjustable pinch roller and the drive roller.
6. The method of claim 1 , wherein the heated endless belt is driven by at least one drive roller.
7. The method of claim 1 , wherein the heated endless belt passes around several idle rollers.
8. The method of claim 1 , wherein the cushioning layer comprises at least one of foam and fiber.
9. A method of manufacturing a laminated soft good, said method comprising:
creating a layered stack comprising a cushioning layer, webs of adhesive on opposite sides of the cushioning layer and outer layers outside the webs of adhesive;
heating a rotating drum with oil;
moving a heated endless belt via a motorized drive assembly thereby pulling the layered stack between the heated rotating drum and the heated moving endless belt; and
heating both sides of the layered stack by passing the layered stack between the heated moving endless belt and the heated rotating drum, heat from the heated endless belt and the heated rotating drum laminating the cushioning layer to the outer layers to create a laminated soft good.
10. The method of claim 9 , wherein the heated endless belt passes around at least three rollers.
11. The method of claim 10 , wherein the at least three rollers includes at least one drive roller and at least two idle rollers.
12. The method of claim 9 , wherein compressing the layered stack comprises passing the layered stack between an adjustable pinch roller and a drive roller.
13. The method of claim 9 , wherein the cushioning layer comprises at least one of foam and fiber.
14. A method of manufacturing a laminated soft good, said method comprising:
creating a layered stack comprising a cushioning layer, webs of adhesive on opposite sides of the cushioning layer and outer layers outside the webs of adhesive;
heating an endless belt with a first heater;
heating a rotating drum with a second heater;
moving the heated endless belt via a motorized drive assembly thereby pulling the layered stack between the heated rotating drum and the heated moving endless belt; and
heating first and second opposite sides of the layered stack by passing the layered stack between the heated moving endless belt and the heated rotating drum, heat from the heated endless belt and the heated rotating drum laminating the cushioning layer to the outer layers to create a laminated soft good.
15. The method of claim 14 , wherein the first side of the layered stack contacts the heated rotating drum and the second side of the layered stack contacts the heated endless belt.
16. The method of claim 14 , wherein the first heater is a radiant heater.
17. The method of claim 14 , wherein the second heater heats oil inside the rotating drum.
18. The method of claim 14 , wherein compressing the layered stack comprises passing the layered stack between an adjustable pinch roller and a drive roller.
19. The method of claim 14 , wherein the cushioning layer comprises at least one of foam and fiber.
20. The method of claim 14 , wherein at least one of the first and second heaters includes a radiant heater.
