  • Web coating apparatus
    Patent number: 5654031
    Abstract: A web coating apparatus includes a supply roll of web and a wind-up spindle for receiving a discrete length of the web. Fluid is discharged from a coating die in a direction toward the wind-up spindle to coat the web as the web is wound about the wind-up spindle. A variable speed pump directs fluid through the coating die at flow rate that is proportional to the speed of advancement of the web. The apparatus is particularly useful for coating discrete lengths of orthopedic splinting and casting tape that is packaged for single patient use.
